Hydrostatic pressure problems

Hydrostatic pressure is a term used to describe a high or rising water table.  In St Louis, water tables can fluctuate dramatically depending on rain fall amounts, snow melt, and drought.  If the water table rises enough, water can come up through cracks in the floor or around the perimeter at the floor and wall seam.  Basement Waterproofing, the installation of interior drainage systems and sump pumps, relieves the hydrostatic pressure and keeps the water table below the basement floor.


EXTERIOR WATER ISSUES

Exterior water issues include standing water in yard, water coming in over top of foundation, window wells filling up, and downspouts dumping next to foundation.  Correcting yard grade, installing french drains, and extending downspouts are effective simple solutions to these problems.

FOUNDATION CRACKS

Foundation cracks can occur for many reasons.  Not all cracks are structural concerns and simple epoxy/urethane injections can be completed to prevent water from entering the basement.  If cracks widen, run diagonally or horizontally they may be a symptom of a larger issue and further structural repairs may be needed.


BRICKS AND DRYWALL CRACKS

Cracks in brick and mortar along with drywall cracking may be a result of foundation movement.  Additional damage may include windows and doors not working properly or sticking.

BOWING OR Rotating WALLS

Bowing or rotating walls are normally a result of lateral movement caused by expanding clay soils.  Expansion occurs during times of heavy and prolonged rains.  The installation of tieback anchors or soldier columns are used to provide structural reinforcement to the foundation walls.  In some cases of highly expansive soils, excavation and exterior pressure relief systems may also be needed to fully solve the issue at hand and not provide just a band-aid to the problem.


SETTLING FOUNDATION

Differential settlement of a foundation can occur for a few different reasons.  One common reason is the shrinkage of clay soils during periods of drought.  Settlement can also occur due to soil erosion, fill material not being compacted properly, etc.  The installation of piers (helical pier or resistance pier) can be used to support the foundation to prevent further settlement.  In some minor cases, water management solutions may be beneficial to help with settlement prevention.
