Many homeowners have the problem of a wet basement at one point or another. The main cause of this is water infiltration coming from the ground on the outside into the concrete or even through solid foundations. There are several options on the market, as far as concrete sealants go, but you must solve your water problem first. Its completely useless to paint the inside of your basement with sealer if there is water seeping in from the outside. Assure your gutters and downspouts are free of debris, check the slope of your landscaping, and lay gravel around the base of your home. Once the water has been stopped from leaking in, make sure you choose a basement sealer that is sodium silicate-based. These type of sealants keep humidity from permeating through the concrete. It will also prevent mold and mildew. This sealer is easily applied with a roller or brush on concrete walls and even floors. Make sure any areas where the paint will be applied, are free of any chemical residues, such as glues or paint. If the problem becomes too much to handle, call a water remediation service, such as DryPatrol.
