Effective Waterproofing & Foundation Repairs

Whether you have foundation problems or your basement frequently floods, we have solutions that can help stabilize and protect your home. Here are just a few of the services we provide throughout Nashville, Cookeville, and beyond:

If you’ve noticed cracking and other irregularities around your home’s foundation, it’s time to call in our foundation repair experts. We can fix absolutely any issue related to a foundation, including replacing the entire foundation of the home. While this may seem extreme, there are occasions when this is necessary. Taking preventive measures now will ensure your foundation’s security and safety, as well as help you avoid more extensive — and expensive — repairs later on.

This process involves sealing the interior underside (concrete walls and dirt floor) of your home from the exterior as best as possible. This is accomplished with rigid foam insulation, liquid foam insulation, caulk, polyethylene tape, wall fasteners, and a thick high-density polyethylene barrier to cover the floors and walls.

Crawlspace encapsulation has many benefits for homeowners. It can lower your energy bills, improve air quality, and keep pests out. 

This process can also help to prevent fungal/mold growth and termite infestations, which can damage your home’s infrastructure.

If you suspect that your basement is wet, give us a call today. There are several basement waterproofing methods we can employ to keep it dry. Exterior waterproofing systems featuring high quality waterproofing membranes are a great way to waterproof your exterior basement walls and prevent future moisture and water buildup. You’ll be amazed at how quickly and efficiently this process can be done!

Interior waterproofing systems enable us to work on the inside of any structure regardless of the foundation type. If your concrete floors are heavily cracked, interior waterproofing is another option to prevent your home from flooding. If your home is prone to hydrostatic pressure seepage, an interior drain tile system complete with a sump pump is another solution. Utilizing interior waterproofing methods is also effective if your home has an adjacent garage on a slab foundation, a porch footer that does not extend down to the depth of the basement foundation, or other large and immovable obstacles such as swimming pools, underground cisterns, and enclosed patios on a slab.

Crawl space repair is any work done in the crawl space prior to installing a crawl space encapsulation system. Some of the processes that we commonly use are:

  • Batt insulation removal (joist insulation) and fungal/mold treatments are normally the first step. The fungus is always removed under a negative pressure to prevent upward movement of active mold spores towards the living space.
  • If water enters the crawl space through the foundation walls, we may recommend interior French drains and a sump pump or positive gravity drain.
  • If wood floor joists are rotted, cracked, or over spanned, causing a bouncy feeling in the home, they will be sistered or removed and replaced.
  • If the sill plate is rotted, causing an unlevel feeling in the home, we will replace and /or splice it as necessary.
  • If the floor joists are sagging (creating humps in the living space floors) at the intersection of the joist and girder or band board, we will cut them free and use joist hangers to raise, level, and permanently support the floor.
  • For excessively sloped floors (>1” over 20 feet) inside the home, we use drop girders and permanent jack posts and footer systems to support and level the floor.
  • For excessive bounce in the floor or if the foundation piers are not contacting the girder, or if wood shims are used, we will replace them with steel shims.
  • If the crawl space door is in poor condition or rusted (allowing hot humid air into the crawl space), we will install a new custom crawl space door.
  • For unsealed below grade penetrations through the foundation wall, we may recommend digging from the outside and sealing cracks to prevent water and animal intrusion.

Discover the ultimate solution for a healthier, more resilient home with crawl space repair. Our expert team is equipped with cutting-edge techniques and top-quality materials to fortify your crawl space against water damage, high humidity, and pests. From sealing cracks to providing effective moisture control, we tailor our services to suit your crawl space’s unique needs.

As you embark on building your dream home, we’re here to ensure a solid foundation and watertight basement. New construction is an excellent opportunity, since it’s the most cost-effective time to install a permanent polymer based waterproofing system that will protect your foundation for good. Our team of experienced professionals is well-versed in cutting-edge construction techniques, offering expert waterproofing and foundation work to keep water out of your basement and crawlspace for a lifetime. Your builder may not be though… 

Ask your builder whether they plan on dampproofing or waterproofing your foundation.  They may use these terms interchangeably, but the difference in meanings can cost you tens of thousands of dollars in future repairs.  Make sure you understand the difference between dampproofing and waterproofing!  Dampproofing is basically a tar coating that is applied to your exterior foundation walls and is currently code in Tennessee.  It generally lasts 2 to 4 years, as your warranty from the builder is usually only one year.  Consider this fact: 50% of the houses that we waterproof are 5 years old and newer.  We have made a living off of builders who dampproof instead of waterproof. 

For our new construction waterproofing process, we use a modified polymer membrane that withstands 8 feet of hydrostatic head pressure as compared to ½ inch of hydrostatic pressure for tar.  The elongation of the modified polymer membrane is greater than 800%, so our waterproofing membrane can expand and contract as your foundation walls move.  Call us today to learn more about the difference and protect your greatest investment.today!

FAQs about Waterproofing & Foundation Repairs

Some of the most obvious signs that you need foundation repair help are:

  • Stair stepped cracks in exterior brick walls
  • Cracked poured concrete walls
  • Stair stepped cracking in concrete block walls of basement
  • Drywall cracks and nail pops
  • Cracked concrete floors (cracked walls may be simply a sign of damage to the drywall or wallpaper; however, if the cracks are large, jagged, or extend into the basement walls or ceiling, there may be an issue with your home’s foundation).

 

Your home’s foundation is a crucial part of its safety. The foundation supports the entire structure of your house, including its walls, floors, and roof. If it’s cracked or weakened, you will need to make repairs before foundation damage worsens. Foundation issues can also cause high indoor humidity and increase your electricity bill. However, with proper solutions, you can keep your property safe, supported, and comfortable. Contact us today for a free evaluation of your foundation!

If your basement is experiencing cracking and bowing walls, it’s time to get help from our experts. Cracks in the foundation walls can indicate several things, depending on the location and orientation. Stair-step cracks are usually indicators of foundation movement from settlement. Horizontal cracking is often an indicator of extreme hydrostatic pressure pushing the walls inward. Bowed walls are also an indicator of major hydrostatic pressure. Settlement and hydrostatic pressure are not good for your home’s longevity.

In the event you have any of these issues, our professionals can evaluate your home and determine the best course of action for repair or replacement of the foundation damage. Most issues can be resolved without requiring replacement of the foundation walls. If you do happen to need new foundation walls, our Barrier crews can handle that too.

Depending on your budget and future plans, damaged foundations can be excavated, straightened, rebarred, and core-filled from the exterior for a permanent and long-term fix. For a more short-term and lower-budget option, the walls can be reinforced from the interior with steel I-beams, carbon fiber strapping, wall anchors, or an intricate web of rebar reinforcement with non-shrink grout.

 

Whichever option you choose, the sooner the issue is addressed the better. Waiting will only result in additional damage and subsequently additional cost for the repair. If you wait too long, the problem could lead to collapsed walls, which will cause extensive damage throughout your home or even render it uninhabitable.

All hardwood floors will naturally expand when exposed to moisture. When only one side of a plank is exposed, that single side will expand. This causes the whole board to warp away from the damp side. Over time, the plank edges curl up, resulting in an unsightly “wavy” appearance.

These problems may arise from seasonal changes, such as rising humidity levels during summer. In these instances, the expansion tends to naturally correct itself when the seasons change and humidity falls. However, cupping, buckling, and otherwise uneven floors may also occur due to faulty plumbing, improper ventilation, poor drainage, and a variety of other circumstances all having to do with excessive moisture in the home.

Regardless of the potential cause of your cupping or buckling floors, this problem requires closer inspection by waterproofing professionals. We can determine the source of this issue and provide you with options to effectively correct it.

The difference between sealing and waterproofing basement walls lies in their respective purposes and methods. Sealing basement walls involves applying a water-resistant coating or sealant to fill small cracks and pores of the interior concrete walls, aiming to reduce moisture and humidity levels inside the basement. This approach helps to control minor moisture issues and prevent unwanted dampness but does not provide a comprehensive solution for stopping significant water intrusion.

On the other hand, waterproofing basement walls goes beyond surface-level treatment. It involves using specialized materials and techniques to create a robust barrier on the exterior foundation walls, that prevents water from entering the concrete walls altogether. Basement waterproofing solutions address not only small cracks or gaps in mortar joints, but also larger openings such as water line or sewer line penetrations and other potential entry points for water. By using a high-tech polymer waterproofing membrane along with a properly installed drainage system, we can effectively manage water and protect the interior of the basement for the life of the home.

Depending on the severity of water issues, a combination of sealing and waterproofing may be recommended to ensure a dry and protected living space. Consulting with our professional basement waterproofing contractors can help you determine the most appropriate solution for your home’s needs — and since we offer free estimates to homeowners, you can’t go wrong by giving us a call today!

Radon is a radioactive gas that results from the natural decay of uranium, which is found in almost all soil. It usually travels along the ground into the air overhead and enters your home through cracks and other holes in the foundation. Your home traps radon gas where it can accumulate. That means old and new homes, well-sealed and windproof homes, and homes with or without basements can all experience radon gas buildup.

If you suspect your home has high levels of radon, you should test for radon concentrations at least once a year. Experts recommend that you test your home twice before installing a radon reduction system. However, you should be aware that the amount of radon in a home can fluctuate seasonally and over time, so a certain test result is not necessarily indicative of an elevated level.

Radon gas buildup is possible in any home, so the type of house you live in will determine which radon reduction system is best for you. Generally, houses are classified by their foundation design: a basement, slab-on-grade, or crawl space. Some houses have a combination of foundation designs, so you may need to combine several different techniques to lower radon concentrations.

Radon mitigation systems utilize a fan to create a negative pressure zone under the slab or vapor barrier. This fan moves the radon gas away from the home, preventing it from accumulating. The system is very quiet and the radon fans can be placed in multiple accommodating areas. Radon fans require minimal maintenance and can operate for years without needing any repairs.

John, Jamie, and the Barrier crew were a pleasure to work with! Jamie provided an easy to understand proposal (cleaning fungal growth, sump basin, vapor barrier) and took the time to explain each aspect and the why's and benefits. The crew was professional and did a fantastic job. Jamie followed up after the job was complete and went through the finished product. I have no hesitation recommending Barrier to anyone!

My home is a one hundred years old English Tudor bungalow in the Belle Meade area that I have owned since 1975. Like many older homes with a basement, it has a dirt shelf in one half. The dirt had been eroding into a concrete floor for some time but I was reluctant to spend money to correct the problem and to find competent people to fix it was a challenge until I met John and Bruce from Barrier. I am not an engineer ( my Dad was) but I knew they could do what I needed done. The work they did far exceeded my expectations. Their workers are dedicated, conscientious and punctual. Overall I am very satisfied.

Family owned and operated, ethical company providing customized solutions for water resolution. The work in my crawl space was completed in a timely manner by a great crew leader-Jeronimo who was in constant communication through completion of all work. I called the rest (about 12 other companies) and used the best - BARRIER IS THE BEST!

We hired Barrier Waterproofing to do my father-in-laws 1950s home, they did an absolutely spectacular job. The owner of the business personally oversaw the work, and helped out to give his team a break, as breaking through the old concrete was not easy or fun! They were easy to talk to and easy to deal with! Highly recommend!

We were are very happy when we found them on the internet to help us with our outdoor drainage issues. John came several times to come up with solutions for our complex issue. He installed outdoor sump pumps and Spee-D channel drains to correct the problem. His employees were very hard workers, did an excellent job and cleaned up everything when they left. Our neighbor even said "they did a great job". We would recommend them and we will use them again, if needed.

My project was underground downspouts extension. All other companies gave quotes for three downspouts extension but BWS gave me one with all seven downspouts extension with PVC pipes including the front ones which required to make a hole under concrete slab. This is far thorough idea which I like considering climate change and more rainfalls in the future.It took three days, the 1st day digging the land, the 2nd day installing pipes, and the 3rd day covering the land. You never know what's under the ground even after having 811 mark all utility lines. There were downspout extension merged line with a neighbor and unmarked gas line for unused street light. Both made my neighbors upset, but BWS took care of it very responsibly and patiently. They were all kind and professional.

John and his team performed way beyond our expectations! When we learned that our foundation was beginning to sink we thought we were going to have to stop our remodeling. In a frantic attempt to find a solution we called Barrier and spoke with John. He was out at our home the next day looking everything over with us. Within 30 minutes he knew what was wrong, why we had water intrusion, and how we were going to fix it. We scheduled a time to have him lift the foundation and place piers to support it. It took 3 days in the sun and rain, but they not only lifted our building, they fixed cracks in the bricks, planted grass in all the areas they dug, and even placed hay to promote the new grass growth. His bid was also great in comparison to two other companies we asked to look at it. Do I recommend Barrier? YES!

My husband and I had been having water issues in our basement for years, it was time to find a company to help us alleviate the problem. Reached out to Barrier Waterproofing and John and his associate made an appointment with us to evaluate the issues and offer us the best solution. I'm happy to say the project was completed on December and we couldn't be happier, no more water!!! The process took 4 days of exterior work on the problem areas with the site supervisor Geronimo explaining every step along the way. He and his assistants were friendly and professional, leaving us with positive feelings that our problem was going to be remedied, and it was. We would highly recommend them to any homeowners or business owners who are experiencing water problems, you won't be sorry. Anita and Bob Bay, Cookeville, TN.

Juan is the hardest working crewman we have ever seen. Arrived each morning on time. Did 90% of the work by hand and by himself in the sweltering heat!! Jose did the excavator work and was the site supervisor. Jose is great, was very nice and also communicated with us well. Bruce was great to work with and communication was top notch. John came to our home a couple of times to answer questions and review job site. Work was extensive but completed as quickly as possible and done sooner than expected since we were told new jobs were 10-12 weeks out on their schedule. (We expected Sept & it was done in Aug). Work was done in 14 days when I expected at least 3 weeks. Job done very well & they cleaned up our yard and completed all work as promised!! We can trust the work and are assured knowing we have a lifetime warranty and never have to worry about our basement leaking again. Thank you!!
