In the links below, you can watch videos recommended by Titan experts for effective waterproofing of bathrooms, roofs, and roof gardens using the Stop Leak waterproofing membrane. 1- Roof Waterproofing: Waterproofing the roof is one of the most common types of waterproofing performed in buildings. Although there is generally no negative water pressure on roofs, due to the direct contact of this part with the atmosphere, paying attention to the climate of each region and having a correct understanding of its changes in selecting the type, method of application, and durability of the membrane is very important. How to Waterproof the Roof? Roof waterproofing is one of the most common types of waterproofing in the construction industry and is commonly done with bitumen-based membranes. Bitumen sheets and asphalt rolls are among the most common membranes used to waterproof roof surfaces. Just as with technological advancements, asphalt replaced bitumen sheets; nowadays, with advancing technology, new mainly polymeric membranes are replacing asphalt rolls by addressing their deficiencies. Choosing the right membrane for the roof is one of the key steps in roof waterproofing. What points should we consider when buying a suitable waterproofing membrane for a building? * Climate: One of the most important factors in selecting a membrane for roof waterproofing is paying attention to the climate where the building is located. Hot weather causes many membranes to soften, which manifests as: * Dripping of the membrane (mostly bitumen) from under the ceiling * Flow of membrane into drains and blocking them * Inability to walk on the roof during hot hours due to membrane softening Cold weather causes many membranes to dry out and crack. Cracking means loss of waterproofing. In the past, contractors addressed these two problems in bitumen sheets by mixing various proportions of hard and soft bitumen according to air temperature, which was a professional job. But more important than the average air temperature is the difference between night and day and seasonal temperature changes. In desert areas where day-night temperature differences are large, and in mountainous areas with significant seasonal temperature variations, the work encounters challenges because even professional mixing cannot fully resolve the problem. * Adhesion of membrane to the surface: This property of the waterproofing material must be examined from two perspectives: 1. Adhesion of the membrane to the dominant surface material 2. Adhesion of the membrane to other materials used on the surface The waterproofing membrane must reliably adhere firmly to the surface and not detach. Therefore, identifying the dominant surface material and estimating membrane adhesion strength is important. Note that sometimes the membrane adheres well to the dominant surface material but because the surface is not uniform and other materials are also present, if the membrane does not adhere well to those parts, detachment there can compromise the entire waterproofing. Considering building surface materials like concrete, cement, brick, stone, mosaic, wood, and metal, it is better to choose a membrane that adequately adheres to all these materials. * Elasticity of the waterproofing membrane layer: Another important factor in membrane selection is its elasticity. If the membrane lacks elasticity, small structural vibrations or thermal expansion/contraction cause cracks and loss of waterproofing. A common example is car tires where cheaper tires are less elastic and crack sooner; likewise, an elastic waterproofing membrane can cover small cracks and maintain waterproofing. * Continuity of the membrane layer: Continuous, seamless membranes are always preferred over strip membranes. With strip membranes like asphalt rolls, joints exist between strips which can allow water infiltration. Overlapping strips partially addresses this but does not eliminate the problem and increases costs. Bitumen sheets and many polymer membranes are seamless, while asphalt rolls are strip membranes. * The slope on which the membrane can be applied: Many membranes like bitumen sheets and asphalt rolls are designed for horizontal surfaces and perform well there, but when applied mistakenly on vertical surfaces, they detach causing loss of waterproofing and potential falling of top layers like tiles. Usually, these membranes are not applied more than 40 cm on vertical walls or are mechanically fixed if applied higher. Roof edges and parapet walls, which are vertical, must also be waterproofed, so membranes capable of application on vertical surfaces are preferred. * Membrane color: Color is a secondary but relatively important consideration. In hot climates, dark bitumen membranes absorb more sunlight increasing heat transfer to lower layers, raising energy consumption for cooling and causing softening of the membrane thus reducing waterproofing quality. Polymeric membranes can be colored as desired, with dark colors preferred in cold climates and light colors in hot climates. This also benefits architectural aesthetics for spaces like roof gardens and allows membranes to be used as a topcoat without additional covering. * Ease and speed of application: The easier and faster a membrane can be applied, especially with fewer equipment and less pollution, the higher its ranking in selection. Method of Roof Waterproofing with Polymeric Membranes: Given these criteria, newer polymeric membranes rank higher for roof waterproofing. One of the best membranes you can use for roof waterproofing is Stop Leak. This membrane is applied as a seamless paint by brush or roller, is very elastic, can stretch up to 4 times its length, and maintains performance between -50°C to +150°C. First, apply a primer layer uniformly on the roof surface, parapet walls, and any place to be waterproofed. Then reinforce only the corners with a 10 cm wide fiberglass mesh. The mesh adheres well to the primer without needing extra fasteners. Finally, apply two layers of Stop Leak in your desired color over the entire surface. Your roof is waterproof. The provided image titled "How to Waterproof the Roof?" shows the application method and appropriate membrane for roof waterproofing. 2- Fountain Waterproofing: In waterproofing of fountains as decorative elements, the most important principle is to avoid affecting their final aesthetic. Additionally, placement next to other elements like moisture-absorbing plaster walls makes fountain waterproofing an engineering and artistic task. How to Waterproof a Fountain? Fountains vary greatly; therefore, one waterproofing method does not fit all. Fountains can be wooden or stone, may be a water wall connected to a wall, or standalone. Adjacent materials vary widely - from moisture-absorbing plaster sensitive even to vapor, to wood that deforms or cracks with moisture changes, or non-porous materials like plastic. All affect fountain waterproofing. For best methods, you can contact us for free consultation from Titan experts. Meanwhile, here are some general guidelines: General rule in fountain waterproofing: The key principle is to preserve the fountain's decorative value; waterproofing should not reduce the artistic merit. Therefore: Always use colorless membranes for fountain waterproofing. How to waterproof a stone fountain? If the fountain is stone, waterproofing is similar to stone facade protection, using either penetration or coating methods. Details are explained in the stone facade waterproofing section. How to waterproof a wooden fountain? For wooden fountains, woods must be completely waterproofed for submerged use. Only water-repelling is not enough. How to waterproof wood and materials useful for full wood waterproofing are thoroughly explained in the wood insulation section. In the images titled "How to Waterproof a Fountain?" suitable products and usage are presented. * 3- Roof Garden Waterproofing: In choosing membranes for roof gardens (roof gardens), besides controlling irrigation runoff, important factors include resistance to hydraulic root pressure, root secretions, and non-reactivity with acids from organic soil decomposition that can degrade the membrane. How to Waterproof a Roof Garden? Consider these points for roof garden waterproofing: Do not forget drainage. Pay attention to root pressure, which can even break asphalt and concrete. Remember that soil and irrigation runoff, due to fertilizer decomposition, root secretions, organic matter, and decaying plant residues, are acidic. Therefore, choose a membrane resistant to acids and corrosion. Since soil and pots need periodic replacement and maintenance like fertilizing and weeding, which involve tools that can physically damage the membrane, choose a membrane resistant to impacts. For waterproofing the roof garden, you can proceed as follows: 1. Cover the surface with a 1 cm thick layer of Isoct, creating a strong barrier against roots and preventing substrate cracks. 2. Reinforce joints between vertical and horizontal surfaces with mesh to prevent cracking at corners that bear the most stress. 3. Use Stop Wet, a two-component polymeric cementitious membrane capable of simultaneously handling positive and negative water pressure, applied with brush or roller. Two layers totaling 2 mm thickness completely waterproof the roof garden. Images titled "How to Waterproof a Roof Garden?" show suitable products and usage for building and waterproofing roof gardens. 4- Brick and Tile Waterproofing: One of the highly practical waterproofing tasks in construction is direct waterproofing of brick and tile surfaces. How to Waterproof Brick and Tile? First, use a colorless, penetrating waterproofing liquid to block all pores and capillaries inside the brick or tile. For this, you can use Top Proof. Top Proof is a colorless liquid resembling water, quickly absorbed by the surface without leaving marks. By penetrating deeply, it blocks all pores preventing water ingress. Remember to spray twice for complete waterproofing - the second application after the first layer dries, applied the same way. After the second layer dries, for increased durability and confidence, apply a coating layer of Prolak on the surface. This also improves surface gloss. Images titled "How to Waterproof Brick and Tile?" show suitable products and their application for brick and tile waterproofing.

In the links below, you can watch the videos recommended by Titan experts for effective waterproofing of bathrooms, roofs, and roof gardens using Stop Leak waterproofing. 1- Stop Leak (Positive Pressure Water Control Waterproofing): Stop Leak is a single-component waterproofing or sealing and protective coating based on water-based copolymers, white in color, with the ability to change color to the employer's desired color. Its properties include flexibility, long durability, and very high adhesion to concrete, metal pipes, and other materials. This waterproofing is specifically designed and developed to control positive water pressure and is not effective for controlling negative water pressure. To control negative water pressure with Stop Leak, the surface must first be coated with a special primer for negative water pressure control, namely Clearband, and then Stop Leak is applied on top. * Applications:  Roof waterproofing  Pool waterproofing  Waterproofing of concrete, stone, and brick tanks  Leakage and dampness fixing in bathrooms, basements, and balconies  Simultaneous painting and waterproofing of facades, especially cement-engineered side facades (western facade) * Features: Stop Leak is highly elastic and can stretch up to 4 times its length. This elastic property allows the waterproofing layer to bridge small cracks that may develop over the years after application, maintaining waterproofing performance. Stop Leak can be easily applied on vertical, horizontal surfaces, and even under ceilings with no height limitations. Stop Leak is applied as a seamless, continuous layer. This increases waterproofing reliability and eliminates extra costs for overlapping and material waste. Stop Leak can be used as a topcoat with the desired color and texture. Thus, it can serve as a decorative element for creating roof gardens and similar applications, fulfilling architects' aesthetic requirements. Stop Leak has very high adhesion to all construction surfaces, including concrete, stone, and even glazed tiles and glass. Vertical tiling and stone setting using adhesive methods is possible on Stop Leak, and for floors, surface covering with mortar is also feasible. Due to its high resistance to UV rays, in addition to indoor use for waterproofing spaces such as bathrooms, it can be used outdoors on facades and roofs for moisture and waterproofing control. Its application is very easy and produces no unpleasant odors or fumes during application and use. * Stop Leak Application Method (Positive Water Pressure): If using Stop Leak for positive water pressure control: First, remove and repair damaged areas such as cracked concrete. The smoother the surface, the lower the consumption of Stop Leak and the more economical the waterproofing. Clean the surface thoroughly, remove dirt and dust, and dry completely. Spray a thin layer of a primer specifically for positive pressure water control onto the surface (1 kg covers about 5 square meters). If spray equipment is not available, you can apply the primer with a brush, which will increase primer consumption slightly. At this stage, reinforce the junction of horizontal and vertical surfaces with a 10 cm wide fiberglass mesh. It is not necessary to cover the entire surface with mesh. Place the mesh on the surface before the primer fully dries while it is still tacky, pressing it gently with your palm. After primer drying, apply Stop Leak. To test primer dryness, place your palm on the surface; if it does not stick, the primer is dry. Drying time is about 2 to 3 hours depending on environmental conditions. Stop Leak should be applied in at least two layers. Usually, two layers suffice for waterproofing, but more may be applied depending on project conditions. Before application, stir the opened bucket for 5 minutes, preferably with a drill and mixer. If mixing manually, increase mixing time to ensure complete homogenization. To change the white color of Stop Leak, add color pigment or acrylic paint (max a few cc or up to 1 kg per 20 kg bucket) at this stage and mix thoroughly. If multiple buckets are used, measure added color carefully for uniformity. Apply the first layer with spray, brush, or roller and let it dry. Drying usually takes 3 to 5 hours but allowing 24 hours is strongly recommended. After this, apply the second layer perpendicular to the first and let dry. This layer dries within 24 hours, but the final drying and testing time is one week for Stop Leak to reach full strength. If using Stop Leak for negative water pressure control: • The steps are similar to positive pressure control; only the primer changes. Use Clearband or Clearproof as the special primer for negative water pressure instead of the positive pressure primer. * Stop Leak Consumption (Negative Water Pressure):  Approximately 700 grams to 1 kg per square meter depending on surface porosity * Safety and Precautions:  This material is not classified as hazardous or harmful to health or the environment; however, ingestion and eye contact must be avoided.  Stop Leak is non-toxic but gloves, goggles, and work clothes should be worn during application.  In case of accidental contact with skin or eyes, rinse immediately with plenty of fresh water.  If swallowed, seek medical attention immediately.  This material is not flammable. * Notes:  Shelf life: 1 year in original sealed packaging  Storage conditions: sealed container, away from moisture and direct sunlight  Optimal storage temperature: 10 to 30 °C  Packaging: 10 kg bucket (8 liters)

Supply of almond sand, chickpeas and washed sand in Asalouye area\r\nIn industrial areas, Asalouye\r\nTypes of sand\r\nCrushed sand: sand obtained by breaking dense rocks such as limestone or granite. Because these sands are artificially produced and not formed by wear, they have a rough surface and sharp corners; Which makes them suitable for making concrete.\r\nWashed sand: It is sand that is washed after processing to remove dust and dirt. This will increase their adhesion in the mortar.\r\nDouble-salted sand: Double-salted sand, as its name suggests, is washed twice. This work makes all the pollution and particles on it to be cleaned efficiently and it is a very suitable option for concreting.\r\nWind-blown sand: Wind-blown sand is a type of natural sand that the wind has caused to move over each other and wear them. The grains of this sand are very small and therefore not suitable for making concrete.\r\nSoil sand: This sand has very small particles like soil and is gray in color.\r\nWhat is sand?\r\nGravel, like sand, is an aggregate obtained by crushing natural stones. The size of gravel is bigger than sand. Based on their shape, sand can be divided into pea sand, almond sand, needle sand and flake sand.\r\nBoth sand and sand are created together, but differences such as size, shape and granularity separate them from each other. The most important difference between sand and sand can be seen in the following cases:\r\n\r\nThe first difference between sand and sand is their size. The size of sand grains is 60 to 2 mm and the size of sand grains is 2 to 0.6 mm.\r\nThe next thing is the price difference between sand and sand. In the construction of large structures, using gravel for the foundation is cheaper than sand.\r\nAnother difference between sand and sand is in the settlement of the structure; This happens less often in structures that are in sand.\r\nSand is more porous than gravel.\r\nAnother important difference between sand and sand is that they use sand in making concrete, but not sand.\r\nAnother difference between gravel and sand is that because there is a larger space between the sand particles, it is easier to move.\r\nThe difference between sand and sand makes it easier for water to move through sand.\r\nSand is mainly quartz and is formed from the weathering of igneous rocks such as granite.\r\nThe difference between natural and broken sand is that natural sand is found in the same way in nature (mainly river beds). But broken sand is made artificially in factories by breaking large rocks.\r\nThe difference between sand and sand according to publications 101 and 55 is that sand is coarse aggregate and sand is fine aggregate.\r\nAnother difference between sand and sand, according to publications 101 and 55, is that sand is obtained from the river or broken stone or a mixture of these two, or from the top of the furnaces. But sand is prepared in natural or broken form.

Supplying and sending matte and shiny masbara in different sizes\r\nThe manufacturer of the highest-quality masbara approved by the employers of large industrial projects in the oil and gas industry\r\nIn industrial areas, especially Asalouye, Chabahar, Jask and other parts of the country\r\napplications\r\nUsing high pressure blasting equipment, this product is the most suitable material in terms of quality and price to remove rust, deposits and prepare surfaces for painting (such as ship hulls). which is used in shipbuilding, bridge construction, steel industry, etc.\r\nThis product is also used in sandblasting operations in the automotive industry, where sandblasting is used to remove some impurities and precisely clean the metals used in car parts.\r\nWhat is Masbara?\r\n Copper slag is a by-product of the process of melting minerals and used metals, which is formed during the separation of metals from impurities in the furnace.\r\nDuring the melting of minerals, the impurities remain floating on the molten metal, which after cooling produces angular granules called mesbareh, which have irregular granulations that are used as abrasives. In general classification, slags can be classified according to processing conditions into blast furnace (BF) slag, air-cooled blast furnace (ACBF) slag, basic oxygen furnace (BOF) slag, and electric arc furnace (EAF) slag.\r\nMasbara specifications\r\nGrit slag is a byproduct of the copper mining process. Due to its hardness and high density, this product has a higher speed and surface cleanliness than other abrasive materials and is the best alternative to common abrasives such as silica. Due to the low percentage of silica, there is no danger to human health, and its price is also low recently due to its large production.\r\n Masbareh and its superiority over silica sand\r\nConsidering that the use of silica sand as an abrasive is more common and in demand than other abrasives in Iran. The advantages of masbara compared to silica sand are stated as follows:\r\nAccording to the classification of slag abrasives in the important and international standard SSPC-AB1, this product is in category A with minimum free silica (crystalline silica) which is less than 1%. This means that there is no It does not cause environmental pollution, while the percentage of free silica in silica sand reaches over 90% due to its purity. That is, the dust produced during blasting is the cause of two dangerous diseases, silicosis and lung cancer. ) becomes\r\nThe minimum hardness of copper slag based on the international standard (ISO-11127-4) is seven mos. which is measured by the glass slide method and has a much higher hardness compared to silica sand. As a result of the contact of this abrasive with the surfaces, it is easy to clean any dirt and rust, rolling oxides and old coatings with high thicknesses, and the surface preparation is done in the best way by providing the maximum adhesion between the surface and the coating.

Grout Polad-2 looks like Grout Polad-1, with the difference that its expansion is very small and only to the extent of compensating the shrinkage of the cement.\r\nBy making further modifications in the formulation of this grout, its mechanical properties have been improved so that its compressive strength has reached at least 650 Kg/cm² with an increase of about 20% compared to Polad-1 grout.\r\n\r\nIndications:\r\n\r\nPrefabricated concrete structures such as walls, columns and beams connecting bolts to foundations, column plates, machinery foundations, crane rails, bridge foundations.\r\n\r\nAdvantages:\r\nPolad-2 grout has more abrasion resistance than Polad-1 grout, so this grout can also be used for hard floors.\r\n\r\nMethod and dosage:\r\nIn order to prepare and use a suitable and ideal grout, it is necessary and necessary to prepare the preparations for doing this work correctly.\r\n\r\nThe suitable temperature for preparing and using grout is 10°C to 30°C, and the working environment and materials should be kept at this temperature. Cold weather slows down the setting time and does not reach the resistance and the ability to work on the grout is lost.\r\n\r\nThe place where the grout is used must be clean and free from dust, oil and grease. This place must have been completely moistened before. At the time of pouring the grout, the proper angle of the grout should be maintained for the unhindered movement of the grout, and the grout should be poured continuously to prevent the formation of air bubbles.\r\n\r\nGrout Polad-2 (G2) is a ready-to-use product that only needs to be added with water of the right quality (without additional potable salts). The amount of water needed to make this mortar varies from 13% to 16% of the weight of the dry materials, depending on the required plasticity.
