Why do we need them.

Expansion joint between concrete slabs.

Without a concrete expansion joint your sidewalk or driveway would crack. It allows for thermal expansion and contraction without inducing stress into the system. Expansion joints are put in place before the concrete is poured. Concrete expansion joints are used to separate slabs and concrete from other parts of the structure.

Do the same for the gaps between the concrete slabs but stop filling the gaps about 2 inches from the top of the slabs. Lightweight over 11 times lighter than traditional products.

Trim a slab trim a slab is made from a rubber like material that flexes and holds itself into the gap between concrete slabs. Expansion joints are used to allow the slab to move and not put stress on whatever it abuts.

It is durable lightweight and flexible enough to shape to contours. It is immune to rot moves with slab expansion and contraction and is not affected by moisture. 1 58 in x 1 68 in x 300 in walnut 1 piece polyvinyl concrete expansion joints. These joint are placed where a slab meets a building where a slab meets another slab and where a pool deck meets the coping.

This material acts as a shock absorber absorbing the stress from the slab s movement. Like i said in the intro these joints allow concrete pads to expand and contract during freeze thaw cycles. Concrete undergoes expansion due to high temperature when in a confined boundary which leads to cracks. An expansion joint is a material placed in the cracks or joints between concrete slabs to protect the slabs from cracking when they contract and expand as the temperature changes.

Expansion joints are placed in concrete to prevent expansive cracks formed due to temperature change. The product includes a 0 5 in.
