*Modern Concrete is not liable for concrete cracks caused by water drainage and freezing under concrete pads. Water drainage must be diverted away from concrete.

**Use of salts or other de-icing chemicals may damage concrete. Modern Concrete warns against the use of salt, calcium, chloride, fertilizers, or commercially prepared de-icing chemicals on concrete surfaces. Salts aggravate freeze/thaw damage, causing the concrete surface to “flake” or spall off. Any substance containing ammonium sulfate or ammonium nitrate will chemically destroy the concrete surface. For safety, Modern Concrete recommends the use of clean traction sand where conditions are icy, as opposed to chemical de-icing. Because some areas use salt on city streets, melt-off of salty slush from your vehicle may also cause damage. Damage caused by de-icing chemicals is not covered by your warranty.
