TEKINJECT PU 1C STOP – Anti-infiltration PU injection resin

TEKINJECT PU 1C STOP is a single-component, low viscosity, solvent-free polyurethane injection system, used with a catalyst (+CAT). On contact with water, it reacts quickly to form a semi-rigid closed-cell foam, capable of stopping water infiltration, even under very high pressure. This resin is designed for the durable sealing of cracks, joints, infiltration points and to create internal waterproofing barriers in structures. MAIN FEATURES Low viscosity: excellent penetration into fine cracks. Instant reaction upon contact with water. Formation of a high density semi-rigid foam. Closed cells: total impermeability after expansion. Solvent-free, high stability and durability. System adaptable according to humidity level and site conditions. FIELDS OF APPLICATION TEKINJECT PU 1C STOP is versatile and suitable for: Waterproofing of concrete structures Fine cracks (from 0.2 mm) up to several centimeters. Construction joints and cold joints. Walls, slabs, slabs, footings, buried walls. Stopping water flow Infiltration under pressure greater than 100 bars. Active leaks in tunnels, basements, technical galleries. Emergency works in the event of structural flooding. Other apps Injection into sealing hoses. Waterproofing of the ground by creating water-repellent barriers. Point consolidation of porous materials. DIRECTIONS FOR USE (Summary) (I can complete this part as soon as you give me the rest of the original document.) Preparation of the support Clean the crack or infiltration area. Drill and install the injection packers. Injection Use an injection pump suitable for low viscosity PU resins. Inject slowly until refusal or until the water stops completely. Polymerization Immediate reaction upon contact with water. Expanding the foam and creating a waterproof plug. Finishing Remove the packers. Fill and smooth.
