"Both Hunter and Carter were very professional, courteous and above all friendly. They arrived on time and began to evaluate the situation of lifting the badly sunken areas of our back patio which in certain areas was at 6? to 7? along the foundation. Hunter then proceeded to explain the whole operation involving the drilling, application of the polyurethane foam and sealing process. He did address a few areas of concern which involved the cracks where half of the concrete panel had lifted 3? to 4? higher than it?s original surface, and that it may not drop back down. After observing the beginning of the operation for a short time it was clearly evident that Hunter and Carter were true professionals and were intent on performing great quality and workmanship, which in the end will always provide and produce a great product. What they were able to do and accomplish of lifting our back patio was truly remarkable, and I cannot commend them enough for their hard work and due diligence."

"We connected on the net , they responded quickly. We decided on a time for the next day. They were on time, ( something unheard of here in St George) got the job done in NO time. I could not be happier or pleased with their ability and knowledge as to how the concrete needed to be opened up without damaging any water lines beneath it. I am a happy camper and would recommend this company totally."

Basement Waterproofing FAQs, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
