Check carefully for the appearance of any of these 8 major danger signs that suggest your basement is being damaged by water:
Wet spots on basement walls
Cracked walls in basement or crawlspaces
Fungus, rot, mold and mildew
Insects and bugs
If your basement has a musty smell, damp walls or floods after a rainstorm, it may benefit from waterproofing. Let our experienced professionals step-in to provide a full inspection and make recommendations for long-lasting results.
Basements are often subject to extreme HYDROSTATIC PRESSURE from the outside of the structure. This pressure often builds up and presses against basement walls causing bowing and cracking. Poor drainage can allow water to seep in through walls, floors, windows and porous concrete. All kinds of problems result from water entering your home. We have found the most common problem area to be where the floor and wall meet.
Even if none of the above problems seem to exist, continue with a more detailed inspection of your basement walls.
Poured concrete walls
efflorescence (a whitish powder) could indicate seepage and porosity that tend to worsen.
Search for vertical or horizontal cracks. Some may have fully penetrated the wall, opening routes for water entry – depending on local water table and soil conditions.
Explore for openings where basement walls and floors meet. Such gaps can admit water and insects, as well as lead to cracked floors.
Inspect mortar joints, especially around below-grade piping and conduits. When leakage appears, your floor space could be rendered unsafe for storage, carpeting or laundering use.
Examine corners where frames butt against foundation walls. These junctures are often uneven, resulting in gaps.
The appearance of efflorescence warns that basement water seepage is threatening your foundations and that cracks will endanger your basement floors.
Check your pipes for excessive condensation.
Masonry block walls
Look for signs of staining in the block closest to the basement floor. This could mean water is building up inside the wall and deteriorating the block’s integrity.
This diagram illustrates additional points of water intrusion (beyond the most common: cover joint). These include leaks from a sump pump, window well, mortar joint, foundation top, wall crack, tie rod, pipe issue, porous concrete, floor drain and floor crack.
