"Couldn't be happier with the results, but the best part of the experience is all the amazing, hard-working, highly dedicated and profesisonal people who work for this company. We have an older home (1984 build) with a very large open, back patio. Water erosion and tree roots had wrecked havoc on the concrete causing joint erosion, extensibe wide cracks, shifting and lift. I didn't want to jack it all up and go to the expense of re-pouring and hoped this would be a smart solution. Joe, Kaly and Mark worked an absolute miracle and the results are exactly what I was hoping for. Their approach was thorough and meticulous and I knew from the get-go I was in good hands. I highly recommend you turn to them for all your concrete repair solutions and I won't hesitate to refer my clients to them in the future. You won't regret it!"

"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

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.
