PVC Waterstops
PVC Waterstop is a conventional waterstop that can be used in a variety of applications. The main usage is to prevent the passage of liquids in concrete joints in many different projects such as Dams, Tunnels, Water & Wastewater Treatment Plants, and other liquid retaining structures.
Typical Properties
water absorption %: 15
tear resistance psi (kg/cm2): 300 (21.1)
specific gravity: 1.38
tensile psi (kg/cm2): 2000 (140.61)
elongation %: 350
ozone resistance: no failur
Bentonite Waterstops
Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant - that means the bentonite waterstop will not expand to point losing much of integrity even being washed away by water during continually expansion
Features & benefits
-Quality sodium bentonite clay and rubber materials
-Moisture activated
-Strong, durable with high cost effectiveness
-High water absorption with excellent compression seal
-High expansion control ability for preserving its integrity
-Controlled internal pressure in surrounding concrete to avoid spalling and cracks
-Withstand high water pressure
-Capable to self-healing
-Easy and fast to transport and install
-Easy to joining
-Non toxic
Applications
-Joints with limited movements
-Construction joints and sheet pile joints
-Water containment and reservoirs
-Water and sewage treatment
-Primary and secondary structures
-Manholes and elevator pits, manure pits
-Tunnels, culverts, dams, water tanks and canals
