 Have you ever encountered a situation where you need to stop leaks immediately from concrete structures that are deteriorating due to sudden guerrilla downpours caused by recent linear precipitation zones? In such situations, "Sokutome-ru" is useful. You can grab it in powder form, press it with your palm, and apply it to the leak for about 10 to 30 seconds. It reacts with water and stops the leak. It's an essential maintenance item for daily use! It can be used in powder form without pre-wetting (except for excessive leaks). Available for sale in a 1 kg box (containing two 500 g recyclable bottles), making it easy to use.

 Non-drying polyolefin-based one-component waterproofing putty "TometaroⓇ", along with the underground beam penetration/external wall penetration FEP waterproofing method "FEP Penetration Waterproofing Kit", two-component mixed liquid resin and curing waterproof material "Raxil-WG", are essential waterproofing materials for "leak prevention and leak treatment" in flood prevention and waterproofing construction. Furthermore, the innovative technology "Water Pressure Resistant Waterproof Manhole Cover" is indispensable for waterproofing work. Manhole covers and machine hatches, which are also essential for the urgent need for "waterproofing" in various structures, are included. These materials are being adopted in various "flood prevention construction" and "waterproofing construction" projects. We kindly ask you to consider our products. Contact : EPJ INC.
