Whenever it rains, water may accumulate behind your concrete block walls. This water can push against the walls and cause structural damage to your home. Additionally, your walls may stain from the seepage, wood can rot, and metal fasteners can rust.
In some cases, your foundation can deteriorate. To prevent this scenario, weep holes are usually drilled near the bottom of your block foundation wall to allow water to escape from your building.
Let’s explore what weep holes are and their purpose in waterproofing your home.
What Are Weep Holes?
A weep hole is a small opening or gap in a concrete block wall that aerates the wall and provides a way for water to escape from your walls. These holes are often used to ease hydrostatic pressure on foundation walls, ensuring a building remains sturdy.
Weep holes are an integral part of basement waterproofing, and they serve the following purposes.
Drainage: The water or moisture that enters your wall cavity needs to escape somewhere. Rather than have it infiltrate your basement, weep holes channel this water into an interior drainage system. From there, the water is directed to a sump pump system that removes it from your home.
Hydrostatic pressure relief: When water gets behind your walls, it creates hydrostatic pressure, which can cause the walls to bow, lean, or buckle. Drilling weep holes along your foundation walls can help alleviate this pressure.
How to Waterproof the Basement
Adding weep holes to your basement wall is an essential part of waterproofing your basement. A typical basement waterproofing job goes like this:
Step 1: To begin with, six to 12 inches of concrete is excavated from your basement floor’s perimeter.
Step 2: Weep holes are then drilled into the foundation walls, typically in the section lowest to the ground. This allows water to flow out.
Step 3: The BasementGutter™ interior drainage system is set around the basement’s perimeter and the perimeter backfilled.
Step 4: Finally, the BasementGutter™ is connected to your sump pump and the floor is replaced.
This solution will channel any water from the basement perimeter towards a sump pump, which ejects it outside.
Benefits of Interior Drainage
Interior drainage systems have many benefits over exterior drainage systems. Here are some of them.
Easy installation – It’s much easier to install interior drainage solutions like the BasementGutter™ system and weep holes than an outdoor drainage system, even if you have a finished basement. The entire process can take 1-2 days.
Stop water ponding – Water ponding is a thorn in the side of many homeowners and can lead to a host of issues such as drywall cracks and mold growth. By installing an interior drainage system, you can avert many problems and create a safer home.
Better protection – Combining weep holes with the BasementGutter™ interior drainage system and a sump pump offers better protection against water infiltration or flood damage than exterior drainage systems alone.
Less invasive – Weep hole installation is less messy and less disruptive than exterior drainage installation, which involves excavation and hauling dirt. Since the weep holes are drilled on the basement interior perimeter, they won’t cause structural damage to the foundation.
Deters mold growth – Interior drainage systems and other solutions like a dehumidifier prevent moisture buildup, which usually creates favorable conditions for mold growth.
Comfortable interiors – Having functioning interior drainage systems also help you avoid problems such as damp floors, cold surfaces, and musty smells, which are common in homes with wet basements.
