An effective water-stopping method for large-scale leaks using hydrophilic water-stopping agents! A waterproof barrier is created on the backside of the structure, ensuring that the water-stopping effect is maintained stably for a long period.
The "Backfilling Method" is a water stop construction method that simultaneously pumps a hydrophilic one-component water stop agent "Rescue Shut S" with water using a dedicated machine in a 1.5-shot method. The "Rescue Shut S" injected under pressure from the drilling penetrates well into the voids in the ground and expands while gelifying the contacted water in a short time. Since it gelifies the contacted water quickly and solidifies while stopping the flow, it achieves excellent water stopping effects even in cases of large amounts of groundwater or leakage from the ground.

Detailed information
-
Drill holes in the structure, install valves, and pump water and sealing agents. During injection, they are mixed in a ratio of 80% water to 20% Rescue Shut S using a Y-shaped pipe at the tool's tip (standard formulation). Due to the pressure from the pump and the expansion pressure from the hydration reaction, the mixture spreads from the drilled holes to the leaking areas and the ground behind the structure, gelifying the water and bonding with soil particles to solidify. This forms a strong waterproof barrier.
