With over 120 years of experience and a highly trained team, we can provide you with the best possible guidance on choosing the right swellable waterstops.
A gunned or place material that is designed to expand to stop water passing through joints in cast in concrete.
Swellable waterstops are placed on one face of the concrete joint prior to pouring the second face of the cast-in concrete.
Swellable waterstops are only used in construction joints (non-movement joints).
Some swellable waterstops are affected by salt or contaminated water. If the ground water is expected to be salty or highly contaminated, it is best to check that the waterstop chosen can perform.
