Have you noticed cracks on your walls recently? Cracks on walls can signify more serious problems than you think, like water damage or even foundation issues.  

Some can be easily fixed with waterproofing, and others need more pressing solutions.  

How can you tell what is causing the crack in your wall? If you are not aware yet, you have come to the right place!  This article discusses types of cracks in walls, their common causes, repair solutions, and other insights.  
 

Types of cracks in walls 
 

A house repair becomes necessary whenever you have cracks in walls. But before proceeding with any permanent solution, you must know about these types of cracks for better understanding -

Hairline cracks -

These are very thin cracks that are often 1/16” wide. They are caused by natural expansion, water intrusion, weather elements, etc.

Vertical cracks -

These often run straight up and down from the floor to the ceiling. They are caused by minor shifts due to temperature changes. 

Horizontal cracks -

These run parallel to the ground and often indicate issues with the building’s foundation, structural movement, or soil pressure.  

Diagonal cracks -

These often intersect with other cracks and are caused by structural movement. Sometimes, they are caused by stress on the building by external forces. 

Stair-step cracks -

These diagonal cracks follow a zigzag pattern across block walls or mortar joints. They are commonly seen in brickwork or masonry and may result from issues with the foundation setting. 

It is important to note that not all cracked walls can be resolved with simple waterproofing solutions. Usually, only hairline cracks and small vertical cracks may be prevented through  house waterproofing, but preventing them is extremely important. 

Other cracks, usually bigger and wider, can be related to your building’s foundation or structure and may require more severe attention.  
 

Wall crack repair and prevention 
 

Repairing walls is best left to experts. However, for knowledge, remember that - wall putty and waterproofing - are two products that help repair walls.  

However, none of the products would work without proper cleaning and application. A lack of proper surface prep and waterproofing often allows moisture to penetrate walls. This leads to water damage that weakens the structure and results in cracks. These types of cracks in walls can compromise the integrity of the building and cause further deterioration over time.  

Here are some preventative measures to ensure long-lasting wall integrity- 

Surface preparation -

Clean and dry the surface of your walls before applying any repair materials. This enables proper adhesion and prevents cracks. 

Waterproofing -

A high-quality waterproofing system is the best solution for preventing hairline cracks in walls and moisture penetration. 

Regular maintenance -

Check your house periodically for water intrusion, discolouration,  peeling paint, cracked walls, and other issues to catch and repair any issues early on.
