Are Weep Holes Effective For Wet Basements? Lombard, IL
Wet basements often occur as a result of water seeping into the basement through cracks as well as crevices in the walls. It can, therefore, seem counterproductive to drill holes in walls. However, these holes (also known as weep holes) are an effective way to protect your basement from flooding.
What Are Weep Holes?
Concrete blocks and cinder blocks make for a robust foundation. However, these hollow blocks are porous. Water from the surrounding soil will seep into the basement through the crevices in the cinder blocks. The exterior of the foundation wall has tar spread as a measure to prevent water from penetrating the concrete or cinder blocks.
Tar is a practical waterproof barrier. However, it degrades over time. It has an average lifespan of about 40 years. That means that if you have an older home with a cinder block or concrete block foundation, there is a good chance that water will begin to seep through the foundation walls soon.
When water seeps through the blocks, it becomes trapped within the hollow of the blocks. Due to the fact that it has no exit, it looks for the path with the least resistance. That is often a crack or crevice, which leads to water seeping into the basement.
Weep holes are just only holes drilled in the blocks. The holes provide an easy path through which the water that has penetrated the blocks can flow. The weep holes direct the water into the French drain.
How Weep Holes Work
Weep holes get drilled into the cinder blocks or concrete blocks that make up the lowest level of the foundation wall. Any water trapped within the walls of wet basements gets directed to the drainage system. These holes are useful for relieving hydrostatic pressure within and on the exterior surface of the walls. They, therefore, protect the foundation walls from bowing and cracking.
The holes also ensure that water from the surrounding soils gets directed into the French drain. The water then gets directed into a well where it collects before being pumped to an external pipe by a sump pump. It ensures the basement remains dry.
Weep holes are, therefore, an essential part of a comprehensive waterproofing system. They are particularly useful for alleviating hydrostatic pressure against block foundation walls. Talk to a foundation waterproofing contractor about having weep holes installed in your basement if you have a cinder block or concrete block foundation.
