A grout injection tube system for water tight cold joints. Easy to install with no damage to the concrete and composed of durable materials. PVC tube with holes, constructed to withstand pressures of freshly placed concrete. Covered by two woven membranes to protect the inner tube from the entry of cement particles (filter, membrane one) and abrasive effects of the concrete aggregates (protector, membrane two).
Designed for use in concrete structures which contain joints where a hydrostatic load on the face of the structure is expected. After injection it reliably prevents water seepage through concrete joints in structures such as parking garages, stadiums, subways, tunnels, swimming pools, water reservoirs, locks, canals, dams, sewage treatment plants, water tanks and similar structures.
