7 Fixes to Avoid Major Foundation Problems
Water is not always our friend. Sure, we drink it, swim in it, and need it to survive, but when it comes to homes, it can destroy the foundation, says home inspector Thomas Dabb of Immaculate Home Inspections in South Orange, N.J. Water can enter a home from the exterior and interior, so buyers and homeowners need to keep their eyes open for signs of its presence—or worse—its damage.
The good news is that there are many experts available to spot and diagnose a problem and suggest the best fix. Water expert Steve Barckley with Exceptional Stone Products in Livingston, N.J., believes that homeowners should start by doing everything possible on the outside of the homes to correct problems and divert water away from a foundation.
Share these seven solutions with clients to help them minimize a foundation’s damage in various scenarios.
1. Improve grading. The slope of a property may direct water toward the base of a single-family house or multifamily dwelling rather than away. Cracks or openings in the foundation then allow it to enter, as well as through higher-level walls, the roof, and other entry points. Fix: “Be sure the grade slopes away from the house,” says Bill Coulbourne, a structural engineer whose eponymous company is near Annapolis, Md. A berm of soil or a swale with planting can prevent water from making its way to a foundation, says Cary Jozefiak, a home inspector with HomeTeam Inspection in Chicago. Caveats: This approach requires periodic maintenance to be sure the berm doesn’t erode. “It also needs to be directed so water doesn’t move toward a neighbor’s property,” Coulbourne says. Using a French drain to allow water to dissipate slowly from near the foundation into the landscape is more environmentally friendly than introducing it into the street to wash away, says Barckley. French drains also require some preventive maintenance to avoid clogging, Jozefiak says.
2. Waterproof a foundation. Keeping the foundation dry will prevent moisture from accumulating on the outside or entering inside. Fix: If wet, the best fix is to waterproof the exterior perimeter and interior walls of a basement or crawl space to prevent capillary action from building up, says New York City architect Victor Body-Lawson of Body Lawson Associates. “What we try to do is create an envelope around a building so water can’t enter through its skin, sometimes with a rain screen that drains water down and out to a storm drainage system,” he says. A sump pump will help if there’s moisture and water inside. It must drain far enough from a house, so water doesn’t recycle back inside if the property slopes or there’s an opening. Home inspector David Rose of Astute Home Inspections in Plainfield, N.J., suggests the drain be at least 5 feet from a house. A backup battery will prove useful if power fails.
3. Install gutters and downspouts. Water flowing off a roof will land near a house and possibly cause damage over time. Fix: A good line of defense is to have both gutters and downspouts installed around a home or building’s perimeter. The downspouts should extend far enough to carry away the water rather than have it sit near a foundation. Jozefiak recommends six feet away from a house. To keep gutters and downspouts functioning, they must be cleaned. How often to do so may depend on the trees near a house, Coulbourne says.Click on the link below to see the remaining 4 foundation fixes: Link
