How Poor Drainage Can Damage Your Brick Masonry

GET A FREE QUOTE

Have you noticed white, powdery stains on your brick walls? Maybe some tiny cracks showing up across the surface? These might seem small, but they’re often the first signs of a bigger issue—poor drainage. When rainwater doesn’t drain properly, it seeps into bricks and mortar, causing them to weaken over time. 

Don’t wait until those cracks spread—reach out to the top-rated masonry contractor in Mobile for a quick inspection.

How Poor Drainage Damages Brick Masonry

Water is the silent enemy of masonry. Without proper drainage, moisture causes several problems:

1. Efflorescence—The White, Chalky Stain

When water evaporates from bricks, it leaves behind salt deposits. They look like white, powdery stains. Even though efflorescence is not always harmful, it is a sign of excess moisture. Over time, trapped water weakens the structure.

2. Spalling—Crumbling Bricks

Bricks expand and contract due to frequent freezing and thawing. In Mobile’s climate, even mild winters can cause damage. When water gets inside, it freezes, creating pressure. Eventually, the brick surface flakes off—a process called spalling.

3. Mortar Erosion—Loose Bricks & Gaps

Mortar is like a glue that holds bricks together. Constant water exposure washes it away. Gaps can be formed, which makes walls unstable. If ignored, entire sections may collapse.

4. Mold & Mildew Growth

Trapped moisture encourages mold. In addition to being unsightly, mold can damage bricks and be harmful to one’s health. Proper drainage is necessary to keep the walls dry and safe.

5. Foundation Shifting

Water pooling around the foundation exerts pressure. It can eventually shift the entire structure. Cracked walls, uneven floors, and sticking doors are warning signs.

How to Protect Your Brick Masonry

Preventing drainage issues saves money and extends masonry life. Here’s what homeowners should do:

1. Check Gutters & Downspouts

Clogged gutters overflow, dumping water near walls. Regularly clean them. Water from downspouts should be directed at least three to five feet away from the foundation.

2. Install Proper Grading

The ground should slope away from the house. If it tilts inward, water pools near the foundation. It helps to improve the yard.

3. Use French Drains

A French drain is a gravel-filled trench with a perforated pipe. It redirects water away from the structure. This is especially useful in low-lying areas.

4. Repair Cracks Immediately

Small cracks let water in. Sealing them early prevents bigger issues. Professionals can assess and fix damage before it worsens.

5. Waterproofing Sealants

Special sealants protect bricks from moisture. However, not all sealants work the same. An expert can recommend the right product.

6. Inspect Regularly

Look for the following signs:

  • Discolored bricks
  • Crumbling mortar
  • Puddles near walls

Early detection prevents costly repairs.
