Slab® is a great fix for concrete cracks. Slab® is extremely elastic and will adjust with your concrete even when it moves with shifting soils, temperature, moisture, or traffic over the years. Easy to smooth out and clean up, use in joints up to 3” wide with no slump. Slab® is specifically formulated for unbreakable adhesion to concrete. The balance of elasticity and adhesion means that your sealant will last for years, not just months. Why put a shiny caulk in concrete? Eye-sore! Slab® doesn’t just repair the crack, it matches your concrete.
