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 that combines liquid unsaturated polyester resin mixed with a hardener and integrates this mixture with reinforcing materials such as glass fibers. Therefore, the resulting waterproof layer has a seamless structure with no joints. ● For more details, please contact us or download the catalog.

We have standardized stable quality with excellent performance in high water resistance, durability, and chemical resistance, primarily using FRP, through method design suitable for various applications. Additionally, we have achieved "low odor" and "low solvent" to consider the construction environment. We have obtained certification based on the "Concrete Corrosion Prevention Guidelines" from the Japan Sewage Works Agency. ● 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 capability. The completed state after construction is seamless, ensuring a thick layer and finishing with an FRP molded tank installed on the inner surface of the water distribution reservoir.

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

The "Poly Roof PP Construction Method Series" achieves cost reduction in structural materials for buildings by lightweight 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 also fully equipped to handle salt damage and bird damage, and is resistant to gasoline and oil, boasting excellent stain resistance and aggregate retention performance. Maintenance after construction is easy, and auxiliary equipment can also be installed. For more details, please contact us or download the catalog.
