Water leaking from wall in basement is one of the common and severe forms of trouble experienced by a homeowner. The cracks can not only cause dampness and mould due to the seepage of water into it, but also will damage the structure of it. Learning about the causes of their emergence, how they should be examined and what methods should be used to fix them is important. In this article, we will help you in recognizing and repairing a water leak.
Understanding Why Basement Wall Cracks Leak Water
Hydrostatic pressure cracks in basement walls usually seep as a result of the pressure applied by groundwater against the basement walls. Our homes are affected by this pressure when the water causes the soil around our homes, gets filled with water and starts to push water through the cracks or every part of the wall that can absorb water.
The other significant one is the freeze-thaw cycle. During cold weather, water that fills small cracks will freeze and expand, and deepen the cracks over a period of time. Furthermore, deteriorating materials and careless workmanship as well as ineffective waterproofing of buildings, are contributing factors to cracks in basement wall and leaking water.
Common Types of Basement Wall Cracks and Their Causes
There are some types of crack in basement wall leaking water:
- Hairline cracks: These are the thin cracks that occur as a result of shrinkage or slight settling; they may also permit penetration of moisture.
- Vertical cracks: This is usually as a result of the settling of the foundations or the soil pushing unevenly on the wall.
- Horizontal cracks: These are worse, and they are evidence of high pressure in the soil or construction pressure; they must be addressed soon.
- Stair-step cracks: Occur on joints on block walls where mortar has been used. Mostly a result of the settlement of foundations or soil.
Inspection of a Cracking Basement Crack
The initial measure dealing with basement water leaks is examination. Investigate moisture behind cracks and near the walls with a moisture meter. Then inspect to identify some obvious indications and this includes discoloration, mould or even efflorescence (the presence of white powder deposits). Inspect the exterior drainage, such as their gutters, downspouts and soil grading to make sure it drains away water that could end up at the foundation. Finally, check and see any cracks and water stains not only on the interior but also on the exterior of the basement wall.
