Stopaq Aquastop 2100 is used to seal cable and pipeline penetrations through structures providing both a watertight and gastight seal to the ducts and pipes into which they are applied. They stop ground water leakages and penetration of possible gas leakage. The Aquastop is confined within the duct by STOPAQ Mortar FR (FLAME RETARDANT) or STOPAQ Mortar WR (WATER RESISTANT) which provide a permanent water tight barrier. STOPAQ Aquastop 2100 can be easily applied and provides a permanent flexible seal to liquids and gases.
