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

EXPAND-Tite Waterstop differs from other expanding waterstop sealants due to its controlled expansion characteristics. Figure 1.1 indicates the manner which EXPAND-Tite Waterstop expands when exposed to full immersion in water.
