Get matched with top basement waterproofing pros in Tularosa, NM

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

• Using dehumidifiers 

• Silicate concrete sealers

• Vapor barriers 

• Baseboard channels 

• Drain tile systems

• Waterproofing paint

• Drainage systems

• Epoxy injection

• Interior French drains

• Exterior excavation and waterproofing

• Cement waterproofing

• Weep tiles

• Liquid membrane

• Sheet membrane 

• Yard grading

• Gutters and downspouts

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

• Water in your basement, including damp walls or puddles on the floor

• Mold spots in your basement

• Musty smells or odors

• Warped doors or walls

• Cracks in walls

• Insect issues, such as cockroaches and termites

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.
