EXPAND-Tite Rate of Expansion

A Highly-Adhesive Sealing Gasket For Use On All Poured-In-Place and Precast Concrete Structures

EXPAND-Tite Waterstop is a unique sealing compound which expands in a controlled fashion when exposed to moisture. EXPAND-Tite Waterstop is manufactured utilizing a specialized mixing process which encapsulates hydrophilic materials into a rubber base creating a controlled, moisture activated sealant. EXPAND-Tite Waterstop has the structural integrity of a rubber-based sealant as well as the ability to expand to create a SELF-HEALING JOINT MATERIAL.

Typical Applications for EXPAND-Tite Waterstop include manhole, box culverts, concrete pipe, septic tanks, manure pits, foundations, slabs, parking garages, retaining walls, storage tanks, tunnels, and similar NON-MOVING, COLD CONSTRUCTION JOINTS.

WHAT DOES CONTROLLED EXPANSION MEAN?

Unlike many of the traditional clay-based products, EXPAND-Tite Waterstop will not expand to a point that the hydration process itself leads to the eventual destruction of the sealant. In-field experience has proven that products which continually expand lose much of their structural integrity and begin to wash away when subjected to a constant flow of water.

The controlled –expansion properties engineered into EXPAND-Tite Waterstop reduces the internal pressures created in cast-in-place applications. Internal pressures can act to cause spalling in foundations and wall structures
