Water Proofing
Basement Waterproofing/ Crawl Space Waterproofing
• Water seepage where the floor meets the wall
• Water leaking through cracks in the floor
• Standing water or puddles of water
• Musty or smelly odors in the basement
• Evidence of mold or mildew
• Bowing, bulging or buckling foundation walls
• Efflorescence
(White chalky powder on the walls)
• Cracked walls
(horizontal, vertical or stair-stepped cracks)
• Cracks in floor, or lifting or heaving of floor
• Peeling paint
• Dampness or wetness on wall or floor
• Water marks or stains on sheetrock, paneling, etc.
• Basement wall discoloration
• Termites, insects or termite damage
• Rust stains
Conditions that Contribute to Water Problems
High Water Table…Rain, snow thawing, underground springs and low lying areas (ie coastal/shore areas) all contribute to a rising water table. The elevated water table can enter the basement through cracks or seams in the floor as well as from up under the footing or through the cinder block walls.

Hydrostatic Pressure…pressure exerted against the foundation resulting from water accumulation or high water tables, the higher the water table, the greater the pressure. As the pressure builds up, the water starts to seep or enter the basement through any cracks or crevices in the walls and floor as well as from up under the footing or through the cinder block walls.

Poorly constructed foundations… lack of exterior foundation waterproofing (ie parging tarring), lack of interior drain systems, non-existent footings(more common in older homes) or cracked footings caused by settlement. Lack of window wells, or improperly installed wells, are just some examples of poor construction.

Poor exterior grading/surfaces….property around the home or structure is pitched towards the home instead of away from the home. Type of soil (clay, iron deposits, green marl, clay marl, etc.) around the home or structure can also play a role in inadequate drainage resulting in water in the basement. Cracked or poorly sloped paved surfaces adjacent to the home or structure or open gaps in these surfaces can create a water intrusion problem. Landscaping overgrowth or edging that is too high and allows for water to collect and not flow away from the home.

Improperly working Gutters and Downspouts…they can be clogged, broken not affixed to the home properly, have become detached or discharge(empty) too close to the home.

Capillary Suction…is the movement of water through porous materials (concrete floors and walls are porous)…the water can be drawn laterally through the walls and upward through small pores in the concrete footing. The effect can appear as dampness or even referred to as “sweating”.
