Using 'Sanmatel Crack Repair'! A case of stopping leakage inside a box culvert.
We would like to introduce a case where we stopped water leakage inside a box culvert due to a large amount of water contained in the embankment during a river improvement project in Okinawa Prefecture. After injecting "Sanmatera Aqua" and "Sanmatera Aqua EX" into the cracks, we applied ultra-fine particle cement (water + special resin mixture) and, after drying, removed the excess material using a grinder or similar tool. The water leakage at the repaired crack areas has been stopped. 【Case Overview】 ■ Location: Certain area in Okinawa Prefecture ■ Period: July to August 2022 ■ Products Used: - Sanmatera Aqua (ultra-fine particle permeable concrete modification reinforcement agent) - Sanmatera Aqua EX (ultra-fine particle permeable concrete modification water-stopping agent) - Sanmatera Crack Repair (ultra-fine particle cement, special water-based resin, inorganic black pigment) *For more details, please refer to the PDF document or feel free to contact us.
