These salts react with the aluminate in the cement, forming an expansive substance. Free water in concrete also swells when it freezes, increasing the volume. Cracks in concrete can also cause the material to expand.
Water will damage the surface finish
When repairing a Concrete Contractor Charleston SC pour, you need to consider whether the concrete is damaged by rain. Although water is an important component of concrete, rain can compromise its finished surface and weaken the mix.

It is therefore advisable to cover the concrete while it is still fresh to prevent the water from damaging the surface.
