-
Water can be a big problem for concrete. Poor drainage and
clay filled base lead to movement and cracking. Proper water run-off
is key to ensuring concrete stays in good condition.
-
Concrete cracks are caused primarily by water getting under
the concrete and poor ground conditions. Rain spouts are often the
source of drainage problems. Make sure water flows away from the
concrete surface - not alongside or underneath it.
-
Water is a bigger problem in winter because of freeze-thaw
cycles lifting and causing excessive movement. In addition, ice
melting chemicals can damage concrete surfaces if not careful. Concentrated
amounts that refreeze on concrete after melting can cause damage.
Ice melting materials refreeze at 20 degrees. Sweep or shovel excess
ice melting materials off concrete to avoid problems.
