How Do I Know When I Need Foundation Repair?

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!

My Basement Has Bowing And/Or Cracked Walls — What’s Going On?

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.

What Is Causing The Buckling And/Or Cupping In My Hardwood Floors?

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.

What Is The Difference Between Sealing And Waterproofing Basement Walls?

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!

What Is Radon And Can It Be Removed From My Home?

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.
