Why fix your wet basement?

For a homeowner or any property owner, a wet basement is one of worst problems to have. When water can come into the basement on a regular basis, a number of bad things happen.

First of all, the space becomes unusable. Any items that are resting on the basement floor need to be moved up and out of the way to avoid direct contact with standing water. Standing water can damage HVAC equipment located in the basement and make a washing machine and dryer unsafe to operate.

Water in the basement also creates ideal conditions for mold to grow on wood, paper, cloth and other surfaces. Eventually mold will destroy most “host” materials, and it can cause wood framing to rot and lose its structural value.

Because it spreads by means of airborne spores, mold can become a serious indoor air pollutant, adversely affecting the health of family members.

What makes our waterproofing system different?

As waterproofing specialists, we understand that in order to be successful, any waterproofing strategy must include a number of critical mitigation measures. In other words, no single waterproofing solution will work effectively to eliminate water in a typical basement or crawl space. Instead, a multi-pronged “battle plan” will be put into play to ensure the long-term effectiveness of this overall waterproofing strategy.

Our basement waterproofing solutions:

  • Exterior water control. It’s important to direct roof runoff and surface water away from the building foundation. A waterproofing specialist will assess the effectiveness of your home’s gutter and downspout system at directing roof runoff away from the house. The specialist may also suggest grading and exterior drainage improvements that move water away from the foundation.
  • Foundation repair. A foundation that is badly cracked, or has settled or shifted, is certain to be susceptible to water problems. A full-service foundation repair contractor like us has the training, technical support and specialized products to make structural repairs to damaged foundations, and to provide complete waterproofing services as well. Instead of hiring separate contractors for foundation repair and waterproofing, it’s more cost-effective and more convenient to let a single qualified contractor do all the work.
  • Interior drainage system. The most-effective waterproofing technique for existing basements (and crawl spaces) is to have a perimeter drain installed where the foundation walls meet the floor. This drainage system collects water that wants to leak into the basement because of hydrostatic pressure, and directs it to a sump pit where it can be pumped out away from the house.
  • Interior sump pump. A sump pump is designed to pump water out and away from the house after the water has been collected by a drainage system and brought by gravity to a sump pit located inside the foundation. The pump turns on automatically when the water in the sump pit reaches a preset level. Better-quality sump pumps have battery backup power so that they can continue working even when electricity from the electric utility isn’t available.
  • Dehumidification. Because masonry naturally absorbs and releases water, a basement is likely to have high humidity levels –even when it has been properly waterproofed. An effective way to remove this excess humidity is to have a dehumidifier installed in the basement. To avoid the hassle of manually emptying the dehumidifier’s reservoir when it fills up, a basement dehumidifier can drain into an existing perimeter drain or sump pit. Many standard dehumidifiers available from appliance dealers don’t have the heavy-duty features to handle basement and crawl space humidity conditions. It’s smart to ask a basement waterproofing specialist about dehumidifiers that will perform well in basement applications.

Our system comes with a lifetime written warranty that's transferable to the next owner, so not only does our system restore value to your house, but it also gives homeowners and buyers confidence that their home is protected.
