An expansion joint divider is a material placed in the joint between concrete slabs when the concrete is poured. They are designed to protect the slabs from cracking when they contract and expand from the changes in tempreture. The material acts as a shock absorber to reduce the stress from the slab’s movement and keeps water from getting under the slabs which can eventually start to lift the slab.
Overtime, the expansion joint material will dry out and rot. Once this happens, it is time to have them replaced.
CONCRETE EXPANSION JOINT REPAIR
If your concrete expansion joint needs repaired, its important to have it fixed and avoid cracks from forming. Repairing these joints professionally insures that the materials being used are correct and more problems are not being created.
ProTec will clean out, prep and replace the joints using a special caulking designed to flex with the movement of the concrete. This will eliminate water and debris from getting under the slabs and provide protection from the elements.
