Why Waterproofing Exterior Crawl Space Walls is Necessary
Spencer Turner • August 9, 2023

Welcome to our blog, where we will discuss the importance of waterproofing exterior crawl space walls. Crawl spaces are prone to moisture intrusion, and if the exterior walls are not properly waterproofed, it can lead to a host of problems. In this article, we will explore why waterproofing exterior crawl space walls is necessary to protect your home's foundation, prevent water damage, and maintain a healthy living environment.



Keeping Water Out

Keeping water out is essential when it comes to protecting your crawl space and maintaining a healthy home environment. Water intrusion into the crawl space can lead to a range of issues, including mold growth, rotting wood, and structural damage. By implementing effective waterproofing measures, you can keep water out and safeguard your crawl space from these potential problems.


The first step in keeping water out is to properly seal the exterior walls of your crawl space. This involves applying a waterproofing membrane or coating to create a barrier that prevents water from penetrating the walls. Additionally, ensure that the area surrounding your home is properly graded to direct water away from the foundation. Proper gutter and downspout maintenance is also crucial to ensure that rainwater is effectively channeled away from the crawl space. By addressing these key aspects of waterproofing, you can effectively keep water out and protect your crawl space from the damaging effects of moisture.


In conclusion, keeping water out is vital for the health and longevity of your crawl space and home. By implementing proper waterproofing techniques, such as sealing the exterior walls and ensuring proper drainage, you can prevent water intrusion and the associated problems it can cause. Taking proactive measures to keep water out will help maintain a dry and structurally sound crawl space, promoting a healthier and more comfortable living environment.

Why Exterior Crawl Space Wall Waterproofing is a Must

Exterior crawl space wall waterproofing is an essential step in protecting your home from water damage and ensuring the longevity of your foundation. Crawl spaces are particularly susceptible to moisture intrusion, which can lead to a range of issues such as mold growth, wood rot, and compromised structural integrity. By implementing proper exterior crawl space wall waterproofing, you create a robust barrier that keeps water out and safeguards your home.


One of the primary reasons why exterior crawl space wall waterproofing is a must is to prevent water from seeping into your crawl space. Moisture can enter through the exterior walls, especially during heavy rainfall or when the ground is saturated. Waterproofing these walls with an effective membrane or coating prevents water infiltration, protecting your crawl space and preventing potential water damage to your foundation. This helps to maintain the structural integrity of your home and prevents costly repairs down the line.


Moreover, exterior crawl space wall waterproofing also helps to control moisture and humidity levels in the crawl space. By preventing water intrusion, you reduce the risk of mold and mildew growth, which can negatively impact indoor air quality and pose health risks. Additionally, controlling moisture in the crawl space helps to preserve the condition of insulation, HVAC systems, and other components that may be vulnerable to water damage. Overall,
exterior crawl space wall waterproofing is a vital investment that ensures the long-term stability and health of your home.

How Waterproofing Exterior Crawl Space Walls Protects Your Home

Waterproofing the exterior crawl space walls is a crucial measure to protect your home from various potential damages. By creating a strong barrier against water intrusion, you shield your home's foundation and structural integrity from harm. When water seeps into the crawl space through unprotected exterior walls, it can lead to issues such as mold growth, wood rot, and even foundation instability. Waterproofing these walls prevents water from entering, significantly reducing the risk of these problems and ensuring the long-term stability of your home.


In addition to safeguarding your foundation, waterproofing the exterior crawl space walls also contributes to maintaining a healthy living environment. Water intrusion can create an ideal environment for mold and mildew growth, which can release harmful spores into the air. By preventing water from entering the crawl space, you mitigate the risk of mold-related health issues such as allergies and respiratory problems. This protective measure helps to promote better indoor air quality and a safer living environment for you and your family. Waterproofing the exterior crawl space walls is a proactive step to protect your home from water-related damages and maintain a healthy living space.

FAQs

  • Can I waterproof the exterior crawl space walls myself, or should I hire professionals?

    While some homeowners may choose to tackle waterproofing as a DIY project, it is often recommended to hire professionals for optimal results. Professionals have the knowledge, experience, and specialized equipment to assess the specific needs of your crawl space and ensure proper installation of waterproofing materials. They can also address any underlying issues and provide long-lasting solutions.

  • How long does waterproofing the exterior crawl space walls last?

    The longevity of waterproofing on exterior crawl space walls depends on various factors such as the quality of materials used, the climate of your area, and the maintenance of the crawl space.

Asbestos was once hailed as a “miracle material” for its heat resistance, durability, and insulating capabilities. For decades, it was widely used in residential construction—especially in insulation, floor tiles, roofing materials, and textured ceilings. However, growing awareness of its severe health risks prompted a series of regulatory crackdowns. So, when was asbestos banned in homes? The answer isn’t straightforward—but knowing the history is essential for homeowners, renovators, and anyone living in a home built before 1990. Asbestos Use in Residential Construction: A Historical Overview Asbestos use in homes peaked between the 1930s and the 1970s. It was commonly found in: Insulation (especially around pipes and ducts) Vinyl (VCT) floor tiles and adhesives (mastic) Roofing shingles and flashing Cement siding (“transite”) Acoustic ceiling tiles Popcorn ceiling texture Joint compounds - like those found in typical drywall Cement products Although concerns about asbestos exposure surfaced as early as the 1960s, it wasn't until the late 1970s and 1980s that its use began to be seriously curtailed - but not eliminated. When Was Asbestos Banned? Contrary to popular belief, asbestos has not been fully banned in the United States. Instead, its use has been heavily restricted through a series of phased regulations: 1973: The EPA banned spray-applied asbestos-containing materials for fireproofing and insulation. 1977: The Consumer Product Safety Commission banned asbestos in wall patching compounds and artificial fireplace embers. 1989: The EPA issued a full ban under the Asbestos Ban and Phase-Out Rule—but it was largely overturned in 1991. Present Day: Many asbestos-containing materials are no longer manufactured or sold, but asbestos remains legal in certain products under strict regulation. Because of this phased and partial ban, asbestos-containing materials can still be found in homes built as late as the 1980s—and even later in some imported materials. How Do I Know If My Home Contains Asbestos? If your home was built before the mid-1980s, there's a high chance it may contain asbestos. However, asbestos is not dangerous unless it is disturbed and becomes airborne. Common risk scenarios include: Renovation or demolition of older homes Damage to aging building material DIY repairs involving insulation or flooring Professional asbestos inspection and testing are the only reliable ways to confirm its presence. Where Can Asbestos Still Be Found in Homes? Even homes built into the 1980s or early 1990s may contain asbestos. It’s often present in: Popcorn/textured ceilings Vinyl tiles and mastic adhesives Duct and pipe insulation Roofing and siding materials Joint compound used in drywall taping What EAS Environmental Can Do to Help At EAS Environmental, our certified professionals specialize in: Asbestos inspections and risk assessments Sample collection and laboratory testing Safe asbestos abatement and removal Post-removal air quality verification We adhere strictly to federal and state guidelines, ensuring that any asbestos-containing materials are handled safely and effectively. Don’t Take the Risk—Test Before You Renovate Whether you’re planning a renovation or simply want peace of mind, understanding your home's asbestos risk is crucial. Ignoring potential exposure can lead to serious health issues like mesothelioma, lung cancer, and asbestosis. Contact EAS Environmental today to schedule a professional inspection and safeguard your property and your health. FAQ – Common Asbestos Questions Q: Is asbestos still used today? A: Yes. Some imported products may legally contain asbestos (e.g., brake pads, roofing, gaskets). Q: Can I test for asbestos myself? A: DIY kits are available but unreliable. Disturbing the material could create a health risk. It is best to consult with a certified professional. Q: What’s the safest way to remove asbestos? A: Consult with licensed abatement specialists who follow EPA and OSHA standards. Q. Can I find asbestos on new homes? A: Yes. Some newer homes may still contain asbestos in imported materials, leftover stock, or legal non-friable products like certain floor tiles or roofing materials. References 1.
