Stamford, Connecticut (PressExposure) September 06, 2006 -- "The corrections of early detected drainage problems are easy, costly reparations of your lawn and foundation are not," says the American Homeowners Association (AHA)(R) President Richard Roll. Early detection is essential. Keep your property safely draining by heeding this timely advice.
Comments: Keeping water away from the foundation is one of the most critical responsibilities of a homeowner. When water has an opportunity to pond (stand), it can lead to severe interior damage to both finishes and furnishings. Water vapor can migrate through concrete as well as through cracks in the soil beneath the foundation. All "soils" must maintain a minimum vertical distance of 6 inches from finish floors / any portion of the wood floor that is subject to decay, to top of finished soil. The 6 inch distance can be reduced to 4 inches if the surface that surrounds the foundation is a hard surface, i.e. concrete or asphalt.
Any water that is standing or ponding within 6 feet of the foundation should dissipate within 24 hours after a rain. Under extreme weather conditions, ponding or standing water may take longer to dissipate. Water that stands or ponds under extreme conditions is considered normal.
Recommended Use and Maintenance:
â¢ Always maintain the required slope away from the foundation. It is advisable to check slope requirements with the local building department, since some cities and counties require slopes to be more than 2%. This means that the soil next to the foundation will be at least 1/4 inch higher than the soil one foot away from the foundation.
â¢ Be especially careful (1) during the installation of landscape materials, where the existing grade could be modified by leveling it out, causing either a negative slope or a flat slope, or (2) when hiring a landscape company that modifies the grade during soils preparation and planting, also causing either flat or negative slope.
â¢ It should also be noted that if gutters and downspouts are not installed, you may want to consider installing them yourself, or having a qualified and licensed expert install them for you. If downspouts are installed, the water should discharge onto approved splash blocks or into a pipe collector system and never towards the foundation.
â¢ Keep all swales, sump pumps, and drains free of silt and other debris.
â¢ Repair any erosion that occurs during a rainstorm. NOTE: If you modify the existing grades that surround the foundation this may cause the soils to subside. You are responsible to monitor and correct this condition.
â¢ Yard drains should be flushed with a garden hose prior to the start of the rainy season and should show evidence of free flow at the curb or at the sump (if applicable).
â¢ If the house is equipped with a subterranean drainage system around the foundation or through the foundation, the cleanouts (if applicable) of this subdrain should be flushed prior to the start of the rainy season. There should be evidence of free-flow through the curb or into the sump.
