Air sheet complex waterproofing method
Patent No. 10-1149745It is a composite construction method of a waterproof sheet with functions such as durability, crack resistance, chemical resistance and elasticity, and an eco-friendly inorganic coating waterproofing agent. It completely solved the problem of the air pocket formation and the seam problem between the sheets, which are problems with the existing sheet waterproofing. It is a method that minimizes changes in the waterproofing layer due to temperature changes and external stimuli as it has a superior protection effect on the concrete structure as it is superior to that of the existing method in blocking external heat.
01Eco-friendly method There is no generation of harmful substances during application
02Insulation method Completely solves problems such as air pockets and seams between sheets, which are problems with existing self-adhesive sheet waterproofing
03Wide application Optimized construction method for waterproofing not only new buildings but also old buildings
04Great flexibility Excellent flexibility to buffer shocks and pressures such as vibration and cracks
05Excellent durability The water-soluble waterproofing agent prevents the rubber component of the waterproofing sheet from melting caused by use of thinner.
06Concrete body protection The double waterproofing of the waterproof sheet and waterproofing film shows an excellent performance in protecting the base surface of the floor.
Exposed and non-exposed waterproofing of the roof of the building, the upper part of the stairwell, the ground exposed floor, and the rooftop balcony

01 Surface preparation
- Scrap off damaged and floating parts of the base surface and use a circular grinder to make the surface smooth and even - V-cut in the place where the cracks are severe on the base surface, and fill it with a crack repair agent and use a high-pressure washer to remove foreign substances. - By mixing Mortar coat and Remital, adjust the water tilling while the water is collected on the substrate.jpg)
02 Waterproofing sheet attachment
- Lay on the completely hardened base surface with a 5mm gap between the curved point and the sheet and between sheets. - Insert the air passage connector between sheets at regular intervals. - Use a water can to pour Hi-powder waterproofing agent between the walls and between the sheets that is 5mm apart to adhere them. - Attach the sheet connecting tape to the connecting part glued with Hi-powder waterproofing agent, and press with a spatula to finish the seam..jpg)
03 Hi-powder waterproofing agent application work
- After stirring Hi-coat (18L) + Hi-powder (14kg) with an electric mixer, apply 1~2 times on the waterproof sheet using a waterproof rake and a large brush. - The total thickness of the waterproofing layer should be 3mm or more including the sheet..jpg)
04 Top coat (exposed)/pressed concrete (non-exposed) application
- When Hi-powder waterproofing agent is completely cured, apply the top coat with a ruler or brush. - When using a non-exposed method, place pressed concrete without a top coater.
