Signs You Need Basement Waterproofing

21 Jul 2021, 09:24 GMT+10

Many homeowners have a basement, which is great for extra storage and living space. However, the basement is a prime location for excess water since it's beneath the ground.

You don't want to wait until you have a water problem to act. It's extremely important to protect your basement from excess moisture.

There are some telltale signs that you need basement waterproofing including:

Water Stains

Examine your basement walls and floor for stains. If you notice water stains, beware. If you can spot signs of seepage from outdoor water intrusion, then you have a problem. Waterproofing is the best way to keep the water out and prevent further damage.

Musty Smell

Basements are notorious for having a 'musty' odor. While the basement will feel cooler and a bit different than your main level, it should not have a strange smell. Basement appliances often create humidity, but they shouldn't cause a smell. A persistent musty smell is a sign of mold and mildew brewing.

Puddles of Water

Never ignore puddles of pooling water on your basement floor. Water can seep in from a source above the ground and create a wet basement. Check outside for standing water as well. Puddles of water in your yard are likely a result of improper drainage, which can eventually lead to leaks in the basement.


Bugs are attracted to cool, moist environments. A basement with excess moisture and water is a bug breeding center. Extermination won't solve the problem if bugs are coming because of water. Instead, waterproofing is essential for keeping the bugs out.


Efflorescence is a white powdery substance that can form on walls. When salt comes to the surface of concrete, it creates this dusty material. Leakage from water to the surface is the cause of efflorescence. If you spot this, it means you need waterproofing.

Cracked Walls and Floors

Check your basement walls and floors for cracks. If you spot them, it's time for waterproofing. Cracks will allow water in, which can wreak havoc on your basement. Waterproofing as soon as possible is more affordable than dealing with water damage.

Bowed Walls

Does the concrete look curved? Is it bulging? Bowed walls are the precursor to cracks that will allow in water. If you have bowed walls, you may need a foundation repair in addition to basement waterproofing to protect your space.
