"A very good and positive experience. Employees Omar and Jumon were very friendly, courteous, and professional. The leveling of my concrete which had a 1? crack and a 1.5? drop is now level as are all the slabs that needed correction, which was every section around my pool. All the cracks and dividers are now sealed as well. The employees worked steady from the minute they arrived until they finished. They well know their job and how to do it correctly. The cost was cheaper than replacing the small damaged concrete area. I highly recommend Groundworks.. They have the right employees, right service, and the right product."

"Superior Excavations Solutions (Brendon) did an excellent job on my brother's anaerobic sewer system! My brother is a disabled veteran so I manage his affairs from New Mexico which can be challenging at times. But Brendon made it easy. He was working against severe rainy weather on a weekend to get this system in and get it up and running. My brother now has a new system and it is working like a charm.. I would highly recommend Brendon to put in any sewer system."

Oasis started in Tulsa in 2024, hauling and doing demo for local contractors — the kind of customers who drop you fast if you're late, sloppy, or slow. We weren't. They kept calling.\n\nNow we're University of Oklahoma students who've brought the business home to Norman — with crews, trucks, and trailers ready, and one of us running Oasis full-time. Licensed, insured, and building our name here the only way we know: show up on time, quote it straight, work harder than anybody, and leave every property cleaner than we found it.\n

Basement Waterproofing FAQs, answered by experts

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

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.
