CONCRETE
Concrete is a hard, white-to-grayish
material used for driveways, sidewalks,
patios, basements, garage floors and
foundations.
Cement is created with a finely
pulverized mixture of clay and limestone,
or other ingredients. When mixed with
other materials such as sand, gravel and
water, cement will set itself into what we
know as concrete.
Because concrete will absorb such things as petroleum-based
products, solvents and paints, it is recommended to use a surface
sealer on your concrete.
Liquid can seep into concrete from either the top or the bottom.
Cracks
Exterior concrete will crack.
Repair cracks with waterproof concrete caulk to prevent moisture
from penetrating to the soil. The caulk will not perfectly match the
concrete.
Although flatwork concrete is generally constructed with expansion
and contraction joints to minimize cracking, some cracks will occur.
Do not park or drive heavy vehicles on your driveway. Stains
Use a stain remover immediately to remove or lessen the
appearance of stains.
Drainage
Check that water is draining away from the exterior concrete and
foundation.
Water should not collect or saturate the ground beside your
concrete.
Landscaping should allow water to drain away from the exterior flat
concrete surfaces.
Proper drainage around the foundation is important. Water that
seeps through basement walls, can damage wall finish materials,
rot wood framing and cause mildew.
Use waterproof sealants or mortar on cracks.
Foundation
Avoid planting shrubbery directly next to the foundation.
Don't edge your flowerbeds with materials that will impede
drainage away from the home and retain water and cause seepage
into basement or crawl space.
Standing water on stoops is not uncommon.
Don't wash your exterior concrete with cold water from an outside
faucet when temperatures are high and the sun has been shining
on the concrete. The change in temperature can damage the
surface bond.
