"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

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you.
