PZ waterstops are hydrophilic strip sealing products which are mainly made of quality vulcanized rubber with smaller size yet high watertight properties.
PN unvulcanization waterstop has less than 300% lower expansibility and better impermeability for underground constructions to prevent infiltration.
Hydrophilic bentonite waterstops with high expansion control ability are economical moisture activated products for all types of water containment projects.
Butyl rubber waterstop is an excellent watertight product taking advantage of its expansion, self-control abilities and harsh temperature resistance.
Mastic waterstop is a hydrophobic watertight product with high adhesion to surrounding dry concrete as well suitable for all types of weather and temperatures.
Tunnel segment gaskets with aging resistance, high compressive strength and good waterproof, can be used in subway, culvert and many underground constructions.
