concrete joint repair products
Perdure EJF
Perdure EJF is a 100% solids flexible epoxy joint filler used
to protect saw-cut joints in concrete slabs on grade or repair existing
damaged joints. Perdure EJF absorbs the impact and shock of heavy
loads and steel wheeled traffic, preventing erosion of control joint
edges.
