Expansion Joints Waterproofing

Expansion joints can be the joints between walls and concrete slabs. Concrete Expansion Joints are cuts in concrete slabs that go completely through the slab to the base material. The purpose of an expansion joint is to allow the concrete slab to expand and contract with temperature changes without cracking the slab.

As with any concrete repair, proper attention to joint preparation is essential to achieving a successful result. Expansion joints should be swept out to ensure that any pebbles, dirt or loose debris are removed.
