Waterproofing a Single Skin Garage Wall: A Comprehensive Guide

Your garage is an essential part of your home that helps protect your vehicles, tools, and other valuables from the elements. However, many garages, especially those with single skin brick walls, are not always waterproof. Water leaks and seepage can cause damage to your belongings, weaken the structure of your garage, and even lead to mold growth.

We will guide you through the process of waterproofing a single skin brick garage wall and ensure that your garage remains dry and protected for years to come.

Why Waterproof a Single Skin Brick Garage Wall?

Single skin brick garages are built without any insulation or vapor barrier, which makes them vulnerable to water damage. Water can easily penetrate through the bricks and cause damage to the interior of your garage.

If left unaddressed, water damage can cause significant structural damage and lead to mold growth, which can be harmful to your health and the environment. Waterproofing your single skin brick garage wall is a crucial step in protecting your garage from water damage and ensuring its longevity.

Choosing the Right Waterproofing Solution for Your Single Skin Brick Garage Wall

There are several waterproofing solutions available for single skin brick garages, including exterior waterproofing, interior waterproofing, and a combination of both. The right waterproofing solution for your garage will depend on various factors, such as the age of your garage, its location, and the severity of the water damage.

Exterior Waterproofing

Exterior waterproofing involves applying a waterproof coating or membrane to the exterior surface of your garage’s brick wall. This solution is ideal for garages that are located in areas with heavy rainfall or high water tables. Exterior waterproofing provides a barrier between your garage and the elements, preventing water from penetrating the bricks and causing damage to the interior.

Interior Waterproofing

Interior waterproofing involves applying a waterproof coating or membrane to the interior surface of your garage’s brick wall. This solution is ideal for garages that have already suffered water damage or have a high risk of water damage due to a high water table or heavy rainfall. Interior waterproofing can also be used in combination with exterior waterproofing for added protection.

Combination Waterproofing

Combination waterproofing involves both exterior and interior waterproofing solutions. This solution provides the most comprehensive protection against water damage and is ideal for garages located in areas with heavy rainfall or high water tables.
