Cracks in the concrete are not only a horrible sight; they can also lead to bigger, more costly problems. You don’t only need to focus on foundation cracks – you need to be cautious of wall cracks and control joint cracks too. You should seal a control joint crack to prevent water, debris and gas entry.
You should seal control joint or expansion joint cracks with the use of sealants designed for that specific use. Your sealant should have the ability to:
- Bond with the sides of the crack.
- Remain flexible, despite changes in temperature or moisture.
- Withstand compression and expansion of moving concrete.
Here are some materials that are suitable for filling or sealing poured concrete slab control joints:
- Pre-fabricated control joint strips of plastic or other material.
- Flexible (usually polyurethane based) radon sealant caulks or masonry caulks.
- Special poly urea caulks that are designed to fill joints and polyurethane foam injection for sealing cracks.
- Semi rigid epoxy resin crack fillers.
- Epoxy products manufactured for concrete expansion joints.
- Hydraulic cements for concrete cracks and leaks in walls, floors or foundations.
Don’t wait till it’s too late to fix the crack. Do it now or get it done by the experts right now. The choice is yours! Your foundation is one of the most important aspects of your home because it supports your entire house. Even if you don’t think of your foundation as your first floor, your house does. Both the structure and the air quality of your basement have an effect on that part of your home that you live and sleep in. Wood rot, cracks, mould, moisture, water and pests can all cause harmful damage to your living spaces and the people who occupy them. Most can be attributed to foundation problems.
