Avoid Crawl Space Waterproofing Mistakes with Expert Advice

Homeowners, do you know what's lurking beneath your home? Crawl spaces can be a mysterious and often overlooked area, but they play a crucial role in the health and foundation of your home. Unfortunately, damp or wet crawl spaces can lead to structural damage, mold growth, and even health problems for you and your family. That's why it's crucial to ensure proper crawl space waterproofing to prevent such issues.

However, many homeowners or contractors make costly mistakes when attempting to fix a flooded crawl space without expert advice. In this post, we'll explore the most common crawl space waterproofing errors, their serious consequences, and how to avert them with the help of professionals. By the end of the blog, you'll have the necessary know-how to maintain a dry and healthy crawl space in your home.

Homeowners, it's time to give your crawl space the attention it deserves. Let's embark on the journey towards a healthier home.

#1 Uncovered Crawl Space Vents: Danger Lurks in Moisture

Many homeowners mistakenly believe that increasing the number of vents in their crawl space will help eliminate moisture buildup. However, the opposite is true. Adding more vents can actually increase moisture levels and lead to pesky mold growth and structural damage. Therefore, covering existing vents to regulate airflow and prevent excessive moisture buildup is crucial. By taking this simple step, you can protect your valuable home and avoid costly repairs in the future.

#2 No-Go Fiberglass Insulation: Mold Menace in Crawl Spaces

Fiberglass is a popular material used for insulation in homes, but it should never be used in crawl spaces. That's because fiberglass is like a sponge and will absorb moisture, creating the perfect environment for the growth of mold and mildew. If you wish to keep your crawl space dry and healthy, it's important to choose an appropriate insulation material that won't trap moisture.

#3 Trapped Moisture Dilemma: When Spray Foam is Not Enough

While spray foam insulation is effective in tight spaces, it may not be the right option for your crawl space. Trapped moisture is a common problem with spray foam insulation, which can lead to mold growth and wood rot. Before choosing an insulation material for your crawl space, consider all the potential risks and benefits.

#4 Key to Drainage: Leak Prevention for Your Crawl Space

Crawl spaces are prone to leaks and standing pools of water, even in homes built to the highest standards. That's why installing a drainage system is important to prevent water buildup and potential damage to your home's foundation. With so many different types of drainage systems available, it's important to research and select the right one for your specific needs to keep your crawl space clean, dry, and free of damage.

#5 Vital Sump Pump: Waterproof Your Crawl Space

When waterproofing your crawl space, it's important to avoid common mistakes that can lead to damage and reduce the system's effectiveness over time. One common issue is the omission of a sump pump basin, essential for ensuring a clean space for the pump to remove water efficiently.

Failing to install the sump pump in a basin can lead to damage from debris buildup, as well as overheating and other issues that can compromise its performance. The best sump pump basin should be installed according to the manufacturer's instructions to ensure your crawl space waterproofing system works at its best.

#6 Don't Risk It: Why Skipping Sump Pump is a Mistake

While it may be more tempting to skip the sump pump and avoid the hassle of installing mechanical devices in your crawl space, doing so could prove much more costly in the long run. A sump pump is typically necessary for flat or lowland areas to effectively remove water intrusion and prevent flooding.

While gravity-feeding waterproofing pipes through the foundation wall may seem like a cheaper alternative, it's important to note that such a setup may not be sufficient to handle heavy rainfall, leading to water overflow and potential damage. Installing sump pumps with a high flow output can help ensure that your crawl space can handle the maximum amount of water intrusion, and multiple pumps may be necessary in some cases to manage the volume of water effectively.

#7 Keep Your Sump Pump Secure: Prevent Damage and Overflow

Your sump pump is a powerful tool for removing water from your crawl space, but it can also be prone to damage and failure if not installed and secured properly. One common mistake is failing to anchor the discharge line to the floor above, which can cause the pump to jump out of the basin or lead to cracks forming in the line. To avoid these splurging issues and ensure that your sump pump can handle the maximum amount of water intrusion, securing it to the floor and anchoring the discharge line as it exits the foundation wall is important.

#8 Check Valves: Protecting Your Waterproofing System

When it comes to a reliable sump pump system, it's not just about the pump itself - you must affirm that you have a properly installed check valve to prevent backflow and potential damage to the pump. Without a check valve, water can flow back into the basin and cause the pump to repeatedly cycle on and off, leading to wear and tear and eventually resulting in failure. To ensure that your reliable sump pump system is functioning correctly and protecting your home from water intrusion, it's crucial to have a check valve installed on every sump pump.

#9 Proper Discharge Line Extension for Effective Waterproofing

If you're installing a sump pump in your crawl space, it's important to ensure the discharge line is properly extended away from the foundation wall to prevent water from re-entering the crawl space or basement. While some contractors may recommend a minimum distance of 15 feet, it's important to consider the slope and terrain of your yard to ensure that water is being effectively diverted away from your home. Ensure your sump pump discharge line is properly installed and extended to avoid potential water overflow and damage to your basement or crawl space.

#10 Biggest Mistake in Waterproofing: Improper Vapor Barrier Installation

A properly installed vapor barrier is essential for long-term waterproofing and humidity control in your crawl space. Unfortunately, many contractors may overlook this crucial step or use an old, ineffective barrier. To ensure that the efforts you put into waterproofing your crawl space are effective and lasting, have a new vapor barrier installed properly by a professional with overlapping and sealed seams and properly secured to the foundation.

#11 Paint or Vapor Barrier? Choosing the Right Wall Solution

When preventing water from entering your foundation walls, you may be tempted to use waterproofing paint as a quick and easy solution. However, without proper application and a high enough rating, these paints may not withstand the hydrostatic pressure inside the walls. Instead, consider using a vapor barrier as a more effective and durable solution that can work in tandem with your waterproofing system.

#12 Avoid Flooding: Invest in Sump Pump Battery Back-Up Systems

When a storm hits hard and your power goes out, your sump pump may not be able to handle the great influx of water that can flood your home's basement or crawl space. That's why investing in a reliable and effective battery backup system for your reliable sump pump is crucial. With an important added layer of protection, you can avoid costly and damaging floods, even during power outages.

#13 Proper Downspout Extension: Protect Your Foundation

If your downspouts are not properly extended away from your foundation, you may be inviting water intrusion and potential foundation damage. Water not diverted from your home can cause flooding in your basement or crawl space foundation and may even lead to bowed or cracked walls. To avoid these problems, ensure your downspouts are extended far enough to safely carry roof water away from your home.

#14 Water Damage Ruins Your Basement? Install a French Drain

Is your basement at risk of becoming a swimming pool? The water that gets on top of your vapor barrier or basement slab is often overlooked in the basement and crawl space waterproofing. Most contractors only concern themselves with flood water under the slab or plastic. But this mistake can be easily avoided with a french drain. This unique product allows water to enter the sump pump basin from above, giving the water access to the pump for discharge. With french drain installation, you can prevent your crawl space or basement from becoming clogged and avoid the damage that comes with it.

#15 Hidden Danger: Poor Crawl Space Door Installation and Water Damage

Your crawl space door may seem like a minor detail, but it can significantly impact your home. Without a properly installed threshold, water can easily seep in and cause expensive damage to your crawl space. This damage can be especially frustrating if you've already invested in crawl space encapsulation. Don't let a poorly installed crawl space door undo all your hard work. Instead, ensure your door is installed correctly with a threshold to prevent water intrusion and protect your home.
