Butyl Rubber Waterstop For Concrete Constructions

Note:

1. Before installation
2. , do not forget to clean and dry the surface of the concrete.
3. Butyl waterstops should be stored in cool, dark and dry environment, away from moistures. 
4. Not appropriate for expansion and moving joints.
5. Please make sure a minimum 2 inches of concrete coverage is left before installation to reduce spalling and cracking of surrounding concrete caused by expansion pressure of the waterstop. When it comes to lightweight, low strength and insufficient concrete with low compressive strength less than ***0 psi, please increase the coverage.
6. Before the second pour of concrete, check the waterstop for premature swell, discontinuity and debris contamination. If so, immediately replace it with a new one.
7. Concrete nails are acceptable to fix the butyl waterstop if necessary.
