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 mold, mildew, and termites, which can damage your home’s infrastructure! 

Some encapsulation systems include a drainage system, sump pump, and dehumidifier to maintain a dry environment in addition to eliminating excess moisture from the space beneath your home. 

High quality ventilation systems help remove moisture and noxious odors from your crawl space, including radon gas. Active radon mitigation systems utilize an electric vent fan that runs continuously and exhaust soil gases that may be contaminated with radon.

If you suspect that your basement is wet, you may be wondering how you can get 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. In the end, you will be glad you did it – you’ll be amazed at how quickly the process can be done!

From cracks to subfloor damage, interior waterproofing is necessary 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 the best solution. Interior waterproofing is also important if your home has a septic tank, as any excavation can be done inside the structure.

If your basement is experiencing cracking and bowing walls, it may be time to have your wall repaired. Cracks in the wall may indicate a water seepage issue. Leaning walls also contribute to cracking and bowing, and this damage can spread throughout the entire basement. Repairing your basement wall is essential to prevent further, more serious damage.

If you’ve noticed cracking and other irregularities around your home’s foundation, it’s time to call in a foundation repair expert. While some damage is too severe to fix, most is repairable. Taking preventive measures now to ensure your foundation’s security and safety can help avoid having to end up paying for more extensive repairs later on.

Sagging floors and sinking slabs are typically an issue when the current support system is spaced too far apart, when soil wasn’t packed sufficiently, when termites have caused damage, or when a house has suffered water damage. By installing a series of stabilizers that are adjustable, the structure can be lifted and supported evenly, reducing damage to the structure.

John Trusa came to our house and gave us great advice based on his knowledge of drainage issues. He pinpointed exactly what needed to be done in minutes! We have been having flooding in our basement for many years and John knew exactly what was going on and how to fix it. We are so thankful he was referred to us.Donna and Charles Goldman

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!!

FREQUENTLY ASKED QUESTIONS

Unlike interior waterproofing, this process involves digging around your house to the base of the foundation walls. Next, a waterproof coating is applied to the foundation walls and finished with drainage panels. Once the coating is dry, drainage panels are installed to carry water away from the house. Exterior waterproofing usually requires a professional contractor for completing the project accurately and efficiently.

In the event that your home doesn’t have a proper drain system, you should consider installing an interior drainage system. This system collects water from below the footing and channels it to a sump pump. An interior drainage system is installed on the inside of your basement wall or footing, reducing mess and expense. Then, a new sump pump will be installed. 

Most crawl space encapsulation methods involve sealing crawl space vents, removing soil to create a subtle grade, and installing a vapor barrier. Crawl spaces are often vulnerable to moisture from the ground below your home. This water can seep into your crawl space, air, and sub-structure, resulting in increased wood damage.

Poor ventilation and improper grading can further compound this problem. Damp wood can attract termites, mold, and mildew and can even lead to costly structural damage. Encapsulation prevents these problems from occurring, lowering your energy bills and preventing excessive outside air from penetrating into your home.

One of the most obvious signs of foundation repair needs is if your walls or floors are cracked. If these cracks are large or have a ragged appearance, the problem may be rooted in the foundation. Cracked walls can even be a sign of damage to the drywall or wallpaper. If the cracks extend into the walls or the ceiling, this could be a sign that the foundation is weakened.

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’re likely to need to make some repairs before the foundation gets worse. A low-quality foundation can also cause high indoor humidity and increase your electricity bill. However, with proper solutions, you can keep your entire house efficient and safe.

Radon gas buildup is possible in any home. Radon is a radioactive gas. It results from the natural decay of uranium found in almost all soils. 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.

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 over time, so a low test result is not necessarily indicative of an elevated level.

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.

Passive radon mitigation systems work with a fan that is installed at the foundation level. It is used to move the radon gas away from the home, preventing it from accumulating in your living spaces. The system is completely silent and the radon fan is not visible as it sits beneath the home. Moreover, it requires minimal maintenance, and the fans can operate for years without needing any repairs. The major drawback of passive systems is that they can’t be used in older homes because their effectiveness decreases as the radon level increases.

If your basement is experiencing cracking and bowing walls, it may be time to have your wall repaired. Cracks in the wall may indicate a water seepage issue. Recent heavy rains may be to blame for a significant increase in damage. Leaning walls also contribute to cracking and bowing, and this damage can spread throughout the entire basement. Repairing your basement wall is essential to prevent further damage.

In the event that there is a severe amount of bowing in your home’s foundation walls, you may need to consider foundation wall replacement. While repairs can temporarily solve the problem, they often are not long-term solutions when hydrostatic pressure is the cause. For walls that are bowing only a few inches, you can consider concrete block repair.

If you wait too long, the problem could lead to collapsed walls, which will cause extensive damage throughout your home. In extreme cases, the walls can even collapsing, which could render your house uninhabitable.

Interior waterproofing in your basement is often the corrective solution after water has already entered the house. Exterior waterproofing, in contrast, is more of a preventative measure for keeping your basement dry and protected.

An internal system is designed to keep water out of your home and away from your foundation. This includes digging a trough that collects water and directs it to a sump pump unit, also known as a French drain.

The installation of an internal drain tile around the perimeter of the foundation is most often done after the construction of the house. This is because they are usually installed in response to a damp basement or sometimes just before finishing a basement remodel. An exterior waterproofing installation is more extensive. These systems are installed outside the foundation to prevent water from entering the basement in the first place, not in response to it.

This process requires excavation around the house to expose the foundation so that a durable waterproof sealant can be applied. Although more extensive than interior waterproofing systems, this type of waterproofing is most effective and preventative.

A sump pump, most often made of cast iron and working at 110 volts of electricity, is designed to sit at the bottom of a pit where the water is collected before being eliminated from the interior of the home to the exterior of the home. When it is working correctly, as the water level rises, a float switch also rises, turning the pump on once it reaches a certain height.

In the event that the sump pump should fail for whatever reason, a secondary backup pump is also installed that runs off of a 12-volt battery backup. This should ensure that in an emergency, the basement will still evacuate the moisture and not become flooded. A trickle charger makes sure the battery is always charged for emergency use. In most cases, once the battery backup kicks in, you might get about a day’s worth of pumping out of it before the battery drains of power. Most units will blare an emergency siren to let you know that the emergency mode is operating.

A crawl space dehumidifier can be part of an effective solution for high moisture level areas, sufficiently maintaining a dry environment even in encapsulated areas. High quality dehumidifiers have a durable design with corrosion-resistant aluminum coils to ensure its integrity. A dehumidifier can remove many pints of moisture a day, and is great for keeping your crawl space dry, even if it has been encapsulated.

If you smell this odor coming from your crawl space, you are not alone!

The odor actually originates from the decomposition of organic material in the soil under the home. This can be compounded by elevated moisture levels in the soil that occur post encapsulation. Once a space is encapsulated, the evaporation of moisture from the soil is greatly reduced. This can result in an increase in moisture which can then reactivate dormant microorganisms that then break down organic material at an accelerated rate—that’s why a crawl space that may not have smelled before the encapsulation may start to smell.

The ammonia released in this process is what creates the cat pee smell. This is because cat pee contains ammonia, the substance that creates the significant smell we associate with cat pee. When organic matter breaks down in the soil, the microorganisms decompose the organic matter back into more basic components. As a result of this process, ammonia is released in high pH soils and less toxic Ammonium in lower pH soils.

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. Consequently, the plank edges can curl up resulting in an overall wavy appearance.

These problems can arise from seasonal changes, like the summertime when humidity levels rise. In these instances, the expansion tends to naturally correct itself when the seasons change and humidity falls. Cupping can also occur due to faulty plumbing, bad ventilation, and a variety of other circumstances all having to do with excessive moisture in the home.

This problem requires closer inspection by waterproofing professionals. We can determine the source of the moisture issue and provide you with options to correct.
