BAMC, Inc. will install a liner that is 20 mil thick and similar to a pool liner. The top edge of the CleanSpace membrane is sealed to the walls with polyurethane sealant. All seams are sealed with a special sealant and 4 inch wide tape made especially for the CleanSpace membrane. BAMC, Inc. seals the polyethylene to the top edge of the foundation wall.
A properly sealed, moisture-protected, and
insulated crawlspace will increase comfort,
save on energy costs, improve the durability of
the home, and reduce entry of moisture, radon,
and other potential irritants or pollutants into
the home. Whichever design is followed, the
keys to an effective crawlspace are:
Moisture control – using a water-managed foundation system to drain rainwater and groundwater away from foundations.
Airtight construction – sealing all air leaks between the conditioned space and the outside prior to insulation installation.
Complete insulation coverage – properly installing the correct insulation levels and making sure the insulation coverage is continuous and complete.
A crawlspace is susceptible to moisture and deterioration problems because of contact with the earth. The best approaches for preventing these problems will depend on the local climate and style of construction, but the following general rules apply to most crawlspace designs.
