"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

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.
