We can help solve your damp, wet or musty smelling basement problems
Exterior basement waterproofing is an effective way to prevent water from entering your basement by way of seepage through foundation walls, mortar joints or by way of the joint between your homes footing and foundation wall.
The benefits are extensive, and with waterproofing the exterior of your home, you’ll save money in the long run.
The most common foundations in Connecticut are either stone and mortar, poured concrete or concrete block and mortar construction. Concrete and block masonry materials are porous and absorb and transfer water much the way a sponge does. To maintain a waterproof basement, you need to either prevent water from contacting your foundation wall or install a system that collects the water and pumps it away from your foundation.
Exterior waterproofing is a heavy membrane that is attached to your foundation wall using a mastic or adhesive which extends from grade level to the base of the wall, across the top and down the side of the footing to create a waterproof seal.
Value Dry adds the extra steps of securing the edges with a metal bar fastened to your foundation wall and protecting the membrane from physical damage with drain-board or foam-board.
Rainwater flows across the surface of your yard, as well as below grade. Water flow is influenced above grade by gravity and obstructions and below grade by gravity and differing soil structures. You have some control over above grade water flow by ensuring the ground slopes away from your foundation and gutters direct water at least 5 feet from your foundation.
Because your house was built by starting with a big hole in the ground, the soil structure is always denser where the soil was not disturbed to build your foundation than the 4-to-5 feet of space against your foundation wall that was loose fill making the control of subsurface water significantly harder.
This creates an area of soil next to your foundation which collects and holds water. Over a relatively short time, the tar that was used to damp proof your home when it was built breaks down allowing water to contact your foundation wall.
While exterior waterproofing may be preferred by homeowners who don’t wish to remove walls and flooring of their finished basement, it will not address hydrostatic pressure forcing water up through cracks in your basement floor. Some method of interior basement waterproofing system would be required to address this condition.
Exterior waterproofing also requires clear working space along the foundation wall. Trees, shrubs, HVAC condensers, propane or oil tanks and similar equipment would need to be removed and replaced by skilled trade’s people to install an exterior waterproofing system.
Despite the difficult installation, exterior waterproofing is the most effective waterproofing solution for preventing wall and cove joint seepage. Unfortunately, the stone foundations of Connecticut are rarely good candidates for exterior waterproofing due to the uneven surfaces limiting the seal that is critical to achieving success.
