Basement Waterproofing – A Complete Guide

August 10, 2023 | Posted in brownbuilding

As the lowermost point, the basement is a vulnerable area during seasonal storms. Prioritizing a basement waterproofing solution could save your belongings. It could also protect your home’s structural integrity from disastrous damage.

What is Basement Waterproofing?

In many areas, heavy rains and melting ice cause severe flooding. If that water enters via the basement, cleanup will only be the start of the problems. High-quality waterproofing prevents moisture and leaks from the outside by utilizing methods like a French drain or sump pump, sealant, and even epoxy fillers.

Main Problems Caused by Wet Basements

If you haven’t considered waterproofing your basement, you risk damaging more than just a few belongings in storage. For example, even if you never experience a flood, you could incur expensive damage due to dampness infiltrating your home’s foundation. Common issues include the following:

Wood Rot and Water Damage

When water soaks into any material, it doesn’t evaporate quickly. Structures of wood will soften and gather mold, making them unstable. And concrete will slowly degrade over time under constant moisture.

Development of Mold and Mildew

Without waterproofing, the dark, potentially damp basement provides the perfect environment for mold and mildew to flourish. They can destroy property, and make the indoor environment unhealthy.

Damage to Stored Items

Moisture destroys things quickly, including documents, photographs, electronics, and fabrics. A waterproofed basement may prevent these issues, saving you from stains, mold damage, and more.

Causes of a Wet Basement

What’s one essential before waterproofing a basement? Experts will need to pinpoint the potential weak points that could allow moisture inside. For instance, check for the following:

  • Flat yard areas
  • Clogged drains
  • Improper drainage around the building
  • Gutters and spouts

Waterproofing basement walls and other surfaces become much simpler after locating these exposure points.

Average Costs of Fixing a Wet Basement

How much does basement waterproofing cost? It depends on the square footage, the products, and the methods used. Also, be sure to ask your waterproofing basement contractors for an estimate that includes basement waterproofing paint and labor costs.

Different Basement Waterproofing Methods

The two main methods include waterproofing your basement walls from inside and outside. While interior waterproofing costs less, exterior methods offer a more effective solution.

Precautionary Measures

When seeking services for “basement waterproofing near me,” opt for exterior waterproofing. Interior waterproofing can offer supplemental protection but will not eliminate the leak’s source.
