New Control Joint System Available

MAR-FLEX® has announced the introduction of a new system to reduce random cracks in concrete foundations. This is accomplished by creating vertical control joints on both sides of the foundation wall. Shrinkage cracking is confined to the control joint area and the outside control joint is sealed to make it waterproof and watertight. MAR-FLEX offers this economical and easy to use system with an additional cost estimated to be $100 to $200 per foundation.

The joint forming material is a reusable plastic extrusion which easily attaches to the edge of any concrete forming system. The joint comes in either +” or 1-1/4” depths and produces a “V” for crack inducement and is available in 8’, 9’ and 10’ lengths. The control joint system should be installed at pre-determined locations where cracks are most likely to occur.
