You Can Not Seal the Gap Between Your Basement Floor and Wall

Everyone wants to protect their homes from water and moisture. One particular area in every home that is vulnerable to water seepage and requires waterproofing is the cove joint. And know that you cannot just seal the gap between your basement floor and wall to fix the cove joint seepage. Learn regarding the problem and waterproofing solutions associated with it below.

What is a Cove Joint? 

The area where your basement wall and floor meet is called a cove joint. Cove joints exist because of the way a home’s foundation is built. During construction, after the foundation footings are constructed, basement walls are poured into the slot. It is after the walls are cured that the basement floor is poured. Due to this, there remains a small gap between the floor and the walls, which is termed as cove joint. A cove joint requires waterproofing.

Why Does the Cove Joint Leak? 

Due to heavy rain, the groundwater around your home rises, which begins to get inside the foundation of your home via any potential openings. Cove joint, a necessary part of the structure is a common entry point for water. As the rains continue, water begins to force itself in through such gaps, which is due to hydrostatic pressure.

Why Can’t the Gap Between Your Basement Floor and Wall Just be Sealed? 

A sealant applied along a cove joint may be a temporary waterproofing solution as it prevents leakage but it eventually fails either as the water finds another gap to enter the home or as the sealant is forced off by the water. This phenomenon occurs due to hydrostatic pressure.

The Best Waterproofing Solutions to Protect Cove Joint 

As learned above, sealing the gap is not recommended, but you have two other options to protect your home from water damage at the cove joint. One waterproofing solution is interior drain tile, and the other is the exterior drain tile system.

Interior Drain Tile 

Drain tile system is the most commonly used solution for cove joint leakage. A drain is installed below your basement floor, which reduces hydrostatic pressure as it directs groundwater away.

An interior drain tile system can be installed without harming your exterior landscaping. Also, it has a lower potential for damage from the roots. If your home does not have any obstructions in the form of nearby buildings for excavation purposes, this waterproofing solution is recommended.

Exterior Drain Tile System 

An exterior membrane installation functions similarly to an interior drain tile system, just that it is installed outside of the foundation rather than inside. Due to outside installation, your basement interior remains intact. The method also prevents moisture saturation in the soil. This can be a far less expensive system to install.
