Many times proper grading and water control
around the house will take care of minor water infiltration into
a basement or crawlspace. The following are some step by step recommendations,
starting with the first and least expensive. Once the conditions
have been changed, routine monitoring of all of the conditions should
be followed.
- Fill any pockets or holes along the foundation,
create a grade away from the house minimum 1 / 2" per foot.
- Extend all downspouts and other water
discharges a minimum of 10' away from structure.
- Remove any overgrown vegetation, bushes,
trees, or root systems.
- Seal the interior of the walls with a
masonry sealer, fill any holes with a hydraulic cement.
- Verify all existing drain tiles for sump
pumps are clear.
Monitor all conditions.
If the conditions persists
- Install a drainfield around the affected
areas in the basement, below the slab. A draintile embedded in
gravel, gives rising ground water a free path to a sump pump,
and to be discharged away from the structure a minimum of 10'
feet.
- There are soil injections available which
come with a lifetime warranty. A polymer is injected into the
soil around the foundation perimeter which seals any cracks or
holes in the foundation.
- There are some other methods collecting
the water at the inside of the wall. However, these methods may
allow deterioration and water damage to the foundation wall.
For these, a professional basement
water proofing company should be consulted with, only as a last
resort.
