PoliRoof is an FRP coating waterproofing material that incorporates the excellent properties of FRP for waterproofing, and the waterproof layer has many features. PoliRoof FRP waterproofing is a coating waterproofing created by mixing liquid unsaturated polyester resin with a hardener and combining this mixture with reinforcing materials such as glass fibers to form a unified layer. Therefore, the resulting waterproof layer has a seamless structure without joints. ● For more details, please contact us or download the catalog.

The "Poly Roof PP Method Series" achieves cost reduction in structural materials of buildings by lightweighting the materials. While the "Asphalt Waterproofing + Protective Concrete Finish" weighs 130 kg/m², the "Poly Roof Pp-1V Method" weighs only 5.1 kg/m². There is no need for protective concrete, joint materials, or finishing boards. Since it can be constructed solely by waterproofing specialists, speedy construction is possible. It is fully equipped to handle salt damage and bird damage, and it is resistant to gasoline and oil, boasting excellent stain resistance and aggregate retention performance. Maintenance after construction is easy, and ancillary equipment can also be installed. For more details, please contact us or download the catalog.

The Purela method is an FRP lining technique for water supply facilities. It is a waterproofing and anti-corrosion method that maximizes the characteristics of FRP lining by combining vinyl ester resin with glass mat, which excels in water resistance, corrosion resistance, and crack-following ability. The finished state after construction is seamless, ensuring a thick layer and resulting in the installation of an FRP molded tank on the inner surface of the distribution reservoir.

The waterproof pan of a collective housing bathroom that is over 20 years old poses a risk of leakage due to aging. To prevent troubles before they occur, we recommend repairing or replacing the old waterproof pan. You can choose the construction method based on the shape and condition of the bathroom. Additionally, for the renovation of traditional bathrooms (tiled bathrooms), "bathroom space" is the best option. We will renovate the floor, walls, and ceiling of the bathroom that cannot accommodate a unit bath to have a 'unit bath style.'
