Weep Holes

Installing weep holes in your basement or foundation wall is an essential part of waterproofing your home.

Schedule Free Inspection

Anytime it rains, there’s the possibility that water could accumulate behind the concrete or brick walls in your home. With time, the water can push out and damage your walls if it has nowhere to go. That’s not to mention that rust, wood rot, and wall stains can develop when this water gets into the basement. 

Every homeowner desires to keep their house safe from water damage. There are various waterproofing solutions that help them achieve this goal. Besides the common fixtures – sump pumps and dehumidifiers – one of the least known and celebrated are the weep holes. They’re an invaluable addition to your home’s waterproofing system and can promote the health of your foundation. 

We encourage you to consider how weep holes could help keep your home and family healthy and safe. These holes allow water that collects behind the wall to escape before it causes problems. Read on to learn more about weep holes.

What Is a Weep Hole? 

A weep hole is a small hole that’s drilled on the base of your foundation wall to provide aeration and an escape route for water. The weep hole also does the following: 

Improves drainage: Rainwater or moisture that gets into the concrete block or brick cavity needs to escape. Instead of leaving it to seep into the basement, the weep hole helps move this water to the interior drainage system, which directs the water to a sump pump so it can be removed. 

Eases hydrostatic pressure: Whether the source is snowmelt or rainwater, any water pushing up against your foundation walls has the potential to cause them to bow or crack. This is called hydrostatic pressure. Weep holes are an effective solution as they help reduce pressure buildup along the foundation walls. 

How to Waterproof the Basement 

Installing weep holes in your basement or foundation wall is the first step to promoting better drainage. Here’s how our experts do it. 

Step 1: First, six to twelve inches of concrete are removed along the interior of your basement floor to properly install the specially designed interior drainage system. 

Step 2: Weep holes are drilled on the lowest section of your walls to facilitate water flow. 

Step 3: An interior drainage system is installed along the perimeter of your basement subfloor and the trench is backfilled. 

Step 4: The basement drainage is connected to your sump pump and your concrete floor replaced. 

If water gets in, weep holes will allow water to drain directly into the interior drainage system, which channels the water to the sump pump. From the sump pump, this water is directed outside your basement. 

The Importance of An Interior Drainage System 

As you can see, weep holes don’t work alone. It’s essential for them to be paired with an interior drainage system like the specially designed BasementGutter™. This device is positioned along the basement floor and wall joints to capture water and relieve hydrostatic pressure. In addition, this system protects against water leakage areas in the floor, porous basement walls, and cracks in the mortar joints. Once in place, the device keeps the basement continually dry without using valuable space or exposing you to excavation risks. Its channels are wide enough to handle huge water flows during rainy weather. Best of all, it is clog-resistant, meaning it won’t back up because of silt or dirt. 

Should I Drill Weep Holes? 

By now, you already know what weep holes are and how they work. You are probably thinking of taking the next step, and that’s installing them in your basement. We wouldn’t encourage you to attempt a DIY, especially if you don’t know what type of foundation walls your house has. Let professionals who know how to drill the holes and integrate an interior drainage system handle the job.
