Are Tar Coatings Effective?
Waterproofing your home to protect it from the many effects of moisture can be complex, as you have many options.
In a previous article, we talked about DIY wall sealants vs. hiring basement waterproofing professionals.
On a related note, this article explains commonly used tar coatings and why they are not permanent basement waterproofing solutions.
Let’s jump right in.
What Is A Tar Coating?

When constructing a home, builders commonly apply a waterproofing substance, known as tar coating or dampproofing, to the walls to prevent moisture infiltration. Another step includes installing a drainage pipe alongside the foundation’s footing to collect any water seepage.
While this time-honored method is relatively inexpensive to apply and can be effective as long as it is not damaged, it’s not without its flaws. The protective tar coating can deteriorate over time, affected by installation practices, cracks or holes in the wall, and exterior humidity and moisture.
Additionally, the drainage pipe can become damaged or filled with debris over time, compromising its effectiveness.
Some homeowners replace these systems, but doing so is problematic for several reasons. Replacement doesn’t prevent the same issues from recurring; the procedure is expensive and involves extensive digging that could severely damage your landscaping, extending well into your yard.
How Do I Know If My Tar Coating Is Failing?
It’s not practical to dig outside your basement walls to check the exterior tar coating’s condition, but you’ll know it is damaged if your basement has these telltale problem signs:
Don’t hesitate to contact your local basement waterproofing professionals at Foundation Recovery Systems when you notice any of these issues. The longer they continue, the damage worsens, and repairs become expensive.
We implement less invasive, longer-lasting basement waterproofing solutions through early intervention.
What to Know Next
Tar coatings are traditional waterproofing methods but do not guarantee long-term protection from moisture. Even if your home’s exterior tar coating remains intact, investing in a comprehensive basement water management system that includes interior drainage and sump pumps is best.

FAQs
Although mold has a distinct odor, other factors like damp materials or plumbing issues can also cause musty smells in basements.
A dehumidifier can help reduce humidity and minor condensation on the walls but will not resolve underlying issues causing the wetness, such as leaks or poor drainage.
Employing waterproofing solutions like interior drainage and sump pumps is the most effective strategy. Additional measures like vapor barriers, dehumidifiers, and insulation provide further protection. Contact us for a free crawl space inspection and repair estimate.
