"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.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.
