A system consisting of a non-bulging, flexible PVC pipe with small oblong holes which act as one-way valves to prevent concrete from getting inside and blocking the pipe during concreting. Instead, they allow the resin to flow to the construction joints. Said openings on the tube ensure a uniform distribution of the injection resin. The tube is placed on the top and in the middle of the joint, also when pouring concrete, it forms a cover and a wall.

Features

• ease of installation and versatility; the product can be injected locally to seal leakage at points
• the multiple elongated holes allow the resin to flow without loss of internal pressure and thus injection pressure
• watertight sealing due to the ingress of resin on both sides of the joint
• a low-cost and quick remedy when it is necessary to seal a water leak through cold joints
• improves the effectiveness and efficiency of standard injection systems based on polyurethane
• great versatility; the tube can be adapted to the place and type of work carried out on concrete structures and joints
• high flexibility of the product that can be used on horizontal, vertical and ceiling surfaces
• non-invasive system, excluding the risk of concrete damage; you do not need to drill a hole first, and the injection packers are connected directly to the ends of the tube section
• suitable for single-component injection system
• good resistance to crushing or other damage that may occur during pouring and laying concrete
• good abrasion resistance; the product is good for "hard" handling during installation work

Application

• sealing structural joints in concrete and masonry structures, generally with MI-LV, where the system has been previously installed
• cutting off water, sealing and flexible filling of gaps and cracks in: structures below ground level: tunnels, basements, cloisters, retaining walls, foundations, garages, etc .; - water supply networks and water retention structures: dams, reservoirs, canals, basins, etc .; sewage system - sewers, manholes, waste water tanks, etc.
• controlling the capillary rise of moisture in masonry
