PASCO Aquastop Waterstop is a flexible hydrophilic polymer rubber waterstop for sealing construction joints and precast panels. When installed Aquastop expands in a controlled fashion on contact with water.
PASCO Aquastop consists of tightly packed charged microscopic platelets. Between and within these platelets there is a separation of charges positive and negative. Water molecules are attracted to the unique clay structure of positive and negative charges and wedge themselves between the platelets causing them to separate & swell. The hydrated bentonite forms a seal preventing further migration of water. As hydrostatic pressure is increased the platelets compact forming a tighter seal.
20mm x 25mm x 5m per roll, 6 rolls per box
Areas of Application Include:
- Underground structures, tunnels, underground stations, box culverts, pits, retaining walls, manholes, basements, precast panels etc.
- Aquastop is used to stop water infiltration through both vertical and horizontal non-moving construction joints, irregular surfaces and around penetrations through concrete.
- Aquastop should not be used as an expansion joint sealant. It is designed to replace conventional waterstops in construction joints.
- The sodium bentonite in Aquastop is the key to its success.
- Bentonite swells when in contact with water to form an impermeable barrier.
- A permanent pressure seal is formed.
