Waterproof Coatings and Treatments, The purpose of cleaning the surface is to remove contaminants and leave the pores open to allow the penetration of the waterproofing compound.
Before starting any procedure or treatment, thoroughly clean the surface of all contaminants like dust, traces of curing compound, oil, and grease. Remove and repair all surface imperfections and protrusions.
Structurally unsound and friable concrete must be removed and repaired with a suitable repair mortar.
Waterproof Coatings and Treatments: Exterior wall treatment
Builders construct external walls with masonry to fill the spaces in the RCC frame containing slabs, beams, and columns. This lends itself to seepage of rain from the external walls to the interiors. Cracks in plasters lead to water seepage. hence, required is a high-performance waterproof coating that would prevent seepage of water from the external walls to the interiors of the building.
Plastered surfaces develop cracks due to deterioration of plaster arising out of bad construction practices, inadequate curing, aggressive climatic conditions, etc. High-performance waterproofing Agent Swishcryl which shall penetrate deep into the surface forming a protective layer protecting the treated surface from water seepages and preventing further crack formation.
Waterproof Coatings and Treatments: Crystalline Treatment (PeneSeal) :
Concrete is porous. Its tunnel-like capillaries are a natural part of its mass and permit the passage of water and other liquids. Chemical treatment fills capillaries, preventing water and liquid penetration from any direction. Utilizing diffusion, the reactive chemicals use water as a migrating medium to enter and travel down the capillaries of the concrete.
PeneSeal CWP is a single-component polymer-modified cementitious waterproofing compound.
The mixed slurry has excellent adhesion and flexibility with concrete/ sand cement screed. During application, it seals the hairline cracks caused by shrinkage or expansion. Moisture channels the mixture, penetrating pores through capillary action, and reaching the lower depths of the concrete. This occurs even in the smallest pores and capillaries.
Waterproof Coatings and Treatments Crack Treatment (Seal n Flux):
Extreme weather conditions, bad concrete mix, bad backfilling and equipment damage can be the culprits to cracks in the structure. Extreme weather conditions entail hot and/or cold temperatures. When pouring a cement wall extreme cold weather can freeze the water in the cement allowing it to expand whereas extreme hot weather dries the cement too fast and shrinks rapidly.
This rapid expansion and compression can crack the cement, especially if there was a bad mix before pouring and the concrete mix had too much water. If the cement doesn’t dry properly, it is fragile and likely to crack. This Waterproof Coatings and Treatments involves identifying cracks and then deeply opening them in a V-shape. We apply Seal n Flux, which has excellent elastomeric properties and water repellency at the molecular level.
Fibreglass Mesh: Waterproof Coatings and Treatments
Alkali-resistant fibreglass mesh offers excellent properties, including water resistance, alkali resistance, flexibility, softness, and resistance to ageing. People widely use it to reinforce walls, natural marble, plasterboard, artificial stone materials, and exterior insulation finishing systems. Fiberglass mesh acts as a bonding agent between the surface and the waterproofing compound.
Waterproof Coatings and Treatments: Pressure / Injection Grouting :
Waterproof Coatings and Treatments -Pressure grouting involves creating pores in the surface using mechanical Drills and injecting grout material into isolated pores. The grouts are cementations, resinous solution chemical mixture. Grouting can strengthen the foundation to support the weight of the overlying structure and also seal water flow through a formation that fills all the void spaces at the structure.
Injecting grout is a cost-effective alternative to excavating and replacing foundations because the polyurethane grout expands to fill all the cracks and voids.
PU Form Grouting :
Injected into cracks and voids via high-pressure pumps, hydrophobic polyurethane grout (PU) effectively stops water leaks in concrete (including honeycombed), soil, pipes, and more. Upon contact with water or moisture, liquid polyurethane reacts and expands, forming a dense, closed-cell foam that effectively blocks water passage. In an unconfined environment, the expansion rate of the material is 20 times its volume.
PU tackles water leaks! It effectively seals cracks and voids in concrete walls, floors, ceilings, joints (expansion and cold), and around pipes. This material repairs leaks in concrete structures. It works on walls, ceilings, and floors in tunnels, even limestone, as well as manholes, sewer lines, and concrete dams.
APP Membrane Waterproofing :
The term APP stands for Atactic Polypropylene which is a waterproofing membrane. The membranes can have fibreglass or polyester as reinforcement. Manufacturers produce APP membrane-modified bitumen membranes from a blend of special polypropylene thermoplastic polymers and distilled bitumen. This combination gives the proven waterproofing qualities of bitumen plasticity, excellent resistance to heat, ageing and weathering, and ease of application by torch welding.
Made with high-quality ingredients and modern techniques, APP Membrane delivers superior waterproofing. Owing to properties like acid resistance, good dispersion, precise pH value and permanent stable colour.
