Basement Waterproofing refers to techniques used to prevent water from entering the basement of a house or other building. Effective below ground waterproofing will include both drainage and sealers.

Waterproofing is needed anytime a structure is built at ground level or below ground. Waterproofing and drainage considerations are especially needed in cases where ground water is likely to build up in the soil and raise the water table. This higher water table causes hydrostatic pressure to be exerted underneath basement floors and against basement walls.


Hydrostatic pressure forces water in through cracks in foundation walls, through openings caused by expansion and contraction of the footing-foundation wall joint and up through floor cracks. Hydrostatic pressure can cause major structural damage to foundation walls and is likely to contribute to mold, decay and other moisture related problems.
 

In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be readily sealed from the interior. Epoxies or urethanes are pressure injected into the openings, penetrating the foundation through to the exterior, thereby cutting of the path of the seepage. These repairs will last for a long time. Many contractors provide 10 year to lifetime warranties on these repairs.

In masonry foundations, interior sealers will not provide permanent protection from water infiltration where hydrostatic pressure is present. Interior sealers are good for preventing high atmospheric humidity inside the basement, from absorbing into the porous masonry and to prevent spalling.

 

Spalling is a condition where constant high humidity or moisture break down masonry surfaces causing deterioration and shedding of the concrete surfaces.

When the foundation is constructed of concrete blocks, an interior drain tile system, described below, can capture the water entering the block system and drain the water into a sump. Typically, weep holes are drilled into the lowest course of block, allowing the drainage to occur. This system will provide a dry and moisture free basement for years to come.
