CETINJECT is a waterstop injection system consisting of an 11 mm (7/16”) diameter hose that functions as a delivery channel for CETCO AKWASEAL waterproofing resins that are injected into the structure after concreting is completed; thus sealing the interfaces and voids within concrete construction joints. Equipped with perforated PVC inner 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).
