External walls are your commercial building’s first line of defense against environmental factors and water damage. To prevent damage to external walls, you must ensure that the correct waterproofing measures are in place and that repairs are made promptly.

What Causes Damage to External Walls?
UV Rays – If the external walls are not properly protected with a UV-resistant coating or sealant, the UV rays can cause the wall to crack and become brittle. The UV rays can also fade and damage external paint.
Water Intrusion – Cracks that are not properly sealed can become a point of water intrusion. The water can seep into the building, damaging the interior materials and causing structural damage.
Debris Buildup – Over time, dirt and other debris can build up on the surface of your external walls. This can not only stain the walls, but also cause them to deteriorate.
Thermal Movement – It is natural for buildings to expand and contract with temperature changes, and as the building settles. If expansion joints are not correctly installed or fail, this can cause the wall to crack.
Signs of Water Damage to External Walls
- Cracks in the Surface of the Wall
- Cracks Around Windows and Doors
- Efflorescence (white, chalky deposits on concrete and brick)
- Peeling Paint
- Damaged Sealant or Coating
- Internal Leaks
- Unexplained Musty Odors Inside the Building
Waterproofing External Walls
Waterproofing Observations – When our team checks a commercial building for water damage, we look at external walls and expansion joints to ensure they are properly waterproofed. We will check the current waterproof membrane and assess if it is still in good condition or if it needs to be replaced. We will also check for cracks or gaps that could be a source of water intrusion.
UV-Resistant Sealants and Coatings – In climates like Houston, UV-resistant waterproofing systems for exterior use are a must. These sealants and coatings will prevent water infiltration, extend the life of the wall, and help maintain your building’s energy efficiency.
Seal Cracks – If our team sees any cracks or gaps during the observation, we will apply a flexible polyurethane or elastomeric sealant. This will prevent further damage from occurring.
Cleanings – Keeping the external walls clean not only enhances the appearance of the building, but also protects the wall as well. Depending on the type of cleaning, this can be done by waterblasting or soft washing. Waterblasting will also prepare the wall for a sealant or coating to be applied if needed.
