Waterproofing method that creates a waterproof membrane on concrete surfaces, suitable for large-scale repairs.
The waterproof layer is highly reliable and can adapt to the conditions of the construction site.
There are various types of "waterproof materials and waterproof construction methods," but for the waterproofing of building rooftops, materials and methods that create a waterproof membrane on the concrete surface are common. Such waterproof layers are highly reliable and are widely used in many buildings. Since each waterproof material and method has its own characteristics, the choice of which method to adopt is determined by considering the type, structure, size, and location of the building, as well as the conditions of the construction site. ■ Construction Examples - Kanagawa Prefecture Housing Supply Corporation - Yuru no Kidai Housing Complex - Azukizawa Family Park - Clean Cove Minami-Ozawa - Chambord Mita

basic information
**Types of Waterproofing Methods (Details)** ■ Asphalt Waterproofing Method - A method that involves pouring melted asphalt onto the substrate while overlapping sheets called roofing. - It creates a highly reliable waterproof layer, but its hardness can change drastically with temperature, and smoke and odors are produced when melting the asphalt. ■ Modified Asphalt Waterproofing - Torch Method - Modified asphalt is a material that enhances flexibility at low temperatures by mixing synthetic rubber with asphalt. - This method involves heating sheets made from this material with a torch burner to melt and adhere them to the substrate. - There is almost no generation of smoke or odors. ■ Sheet Waterproofing Method - A method that involves adhering waterproof sheets made from synthetic rubber or polyvinyl chloride resin to the substrate using adhesives. - It excels in design and workability, but the use of adhesives can produce odors. ■ Coating Waterproofing Method - A method that involves applying liquid resin such as urethane rubber to the substrate and curing it to form a waterproof layer. - The waterproof layer has no seams and is aesthetically pleasing, but there is a possibility of quality variation due to temperature and weather conditions immediately after construction.
