Bathroom renovation method 'Yokuhari Space' proposed by FRP waterproofing manufacturers.
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."

Additionally, we also offer "Water Proof" for porous stone and brick. 【Features】 ■ Mold-resistant specification ■ Forms a silicone waterproof layer ■ Recoatable ■ No cloudiness due to alkaline crystals ■ Prevents water penetration into deteriorated tiles and joints *For more details, please refer to the PDF document or feel free to contact us.
I want to remove asbestos-containing finishing materials! For sites where I want to proceed to the next step while preserving the base adjustment material! It is possible to completely remove even the slightest residue of the coating material.
The "Water Clean Stripping Method" is a technique that allows for unevenness adjustment while preserving the underlying leveling material after removing asbestos-containing finishing materials. It can completely remove even the slightest residue of the coating material and can remove materials regardless of whether they are organic or inorganic. The applicable conditions are that only the finishing material contains asbestos, while the underlying leveling material does not, and it can be applied in sites where the next process (such as repainting) is desired while preserving the underlying leveling material, or in sites where no underlying leveling material has been installed. 【Features】 ■ Unevenness adjustment can be performed while preserving the underlying leveling material ■ Complete removal of even the slightest coating residue ■ Removal possible regardless of the components of the finishing material (organic or inorganic) ■ No additional work required like multiple applications of the stripping agent method *For more details, please refer to the related link page or feel free to contact us.

Even if rainwater penetrates the waterproof layer, a specially shaped metal plate with a slope ensures a drainage path!
The open joint method of the "Sky Promenade" is designed to match wooden houses that exhibit seismic resistance by dispersing forces through movement. The play at the joint sections, or "relief," helps avoid situations that could lead to surface cracks, preventing cracks that could cause water leaks. Additionally, even if rainwater penetrates the waterproof layer, a specially shaped metal plate with a slope ensures a drainage path. It drains through a four-layer structure. This joint, which "allows rain to escape and prevents rainwater from entering," is a necessary structure for wooden houses to survive without resisting natural phenomena. 【Features】 ■ Allows rain to escape and prevents rain from entering ■ Drains through a four-layer structure ■ Weighs 1/16 of traditional Japanese tiles, resulting in a lower center of gravity and reduced load *For more details, please refer to the related link page or feel free to contact us.
