PolyRenewal™ Concrete Leveling and Lifting in Thornton, CO

A shifting, weak soil base can cause your concrete slap to be sunken in. When your home's surfaces are uneven, you are limiting your home's full potential and exposing your loved ones to a dangerous falling hazard.

The standard leveling system from other companies is a slabjacking or mudjacking, which involves a contractor smashing your concrete slap, causing a loud distraction to you and your neighbors and a mess on your lawn. So choose the best system that will level your home without all the stress and the mess.

PolyRenewal™ solution from Complete Basement Systems is clean, reliable and stress-free. Our highly-skilled specialists will drill small holes in the slab, inject a polymer solid that will fill the space underneath it, and ultimately raise and level your slab. Our system is guaranteed to last for your Thornton, CO home!

Fixing a Leaky Basement in Thornton, CO

Patricia M., a longtime resident of Thornton, Colorado, noticed that her carpeted floors in her basement were damp after a particularly strong rain. However, she didn't really think much of it, because it had never happened before, and it might have been caused just by the sheer amount of rain. Six months later, she noticed her floors were damp again, especially around the edges of her basement floor. She also began to see water dripping in from her window wells. Knowing that this problem would certainly only get worse, Patricia decided to call Rod Martin's Complete Basement Systems for a free estimate.

When one of our Design Specialists made it out to Patricia's Thornton home, it was determined that, in order to mitigate the water intrusion, Patricia would need our BasementGutter drainage system, attached to a SafeDri Triple Sump Pump system. Patricia's old sump pit, which was little more than just a bucket dug into the unfinished part of her basement, was replaced with the SafeDri Triple. Also, to handle the latent humidity in her basement, we installed a self-draining dehumidifier in Patricia's basement, and attached the device right to the SafeDri Triple.

Now, Patricia's basement is clean, and, most importantly, dry, all thanks to Rod Martin's Complete Basement Systems!

Thornton Concrete Leveling

A Thornton, CO homeowner was having concerns about cracked concrete in his home. Cracks in his walls and in between the wall and the floor (wood and tile) were starting to get to large and the homeowner wanted to find the right company to make his basement beautiful again. After seeing a commercial for Rod Martin's Complete Basement Systems he decided to get a free estimate and set up a scheduled project!

Our talented foreman and installation team decided the course of action to take and started the project in Thornton. To begin the project they removed some of the existing flooring in order to get enough space to inject the poly product. They raised the floor by injecting the poly product underneath the concrete which lifted it up and leveled it with the wall and the remainder of the concrete floor slabs. They did this process both by the walls and by the entrance tile floor.

After completing the project, the Thornton homeowner has been able to achieve peace of mind!

Thornton Crawl Space

Rachel of Thornton, CO was having crawl space concerns. She was aware that she needed to seal her crawl space for future water damage and insulate it as well for lasting protection. She wanted her crawl space to stay dry and insulated as well as be able to drain water out. She had heard of Rod Martin’s Complete Basement Systems through neighbors and decide it was the most trusted company in the area.

Our expert installation team set out on the job and had the best solutions for Rachel’s crawl space needs. The team first put down good soil in the crawl space. After putting down the soil they sealed the crawl space which not only looks great but will also fully protect the space from water damage. The walls of the space were lined and insulated and sealed off. For even more drainage protection the team installed drainage matting and a vapor protection product.

After the team left the home, Rachel has been able to feel a peace of mind knowing her crawl space is in amazing condition!

Thornton, CO
After 2 years of procrastination and multiple bids I recently contracted with CBS to encapsulate our crawl space.  The crawlspace always emitted a musty smell.  I elected to install ExTremeBloc insulation, crawl space insulation and Drainage Matting along with the CrawlSeal vinyl to ensure that I obtained highest level of sealing and insulation. Scott Widick, our Design Specialist, was very professional and knowledgeable.  He answered all of my questions and was very patient in working with me as I'm very detailed.  The installation team of Rogelio and Jesus were "outstanding" especially Rogelio.  He handled everything in a very timely and professional manner, was polite, paid attention to the little things and was a pleasure to work with.  He's the type of employee that any company would love to have on their team.  I'm highly satisfied with my decision and the quality of the work. Congratulations to Rod Martin for developing an excellent team of people who enjoy their job and take pride in their work!

From sales to install, Rod Martin’s team was honest, easy to work with and punctual. Jose and his install team were communicative, friendly and helpful. They did a great job sealing our crawlspace while dealing with very low clearance, finished before they expected and stayed to budget. Jose went the extra mile to assure my alarm was wired to an area where I would hear it, which I was not expecting but really impressed me.

Humberto and Jose are excellent professionals and go beyond their assigned duties. They fixed a leak in crawlspace pipes after identifying problem. They could have had us call a plumber! I am very impressed with these 2 gentleman.

I am the listing agent for the owners. The house is going on the market and my concern is the severe heave in the basement floor. The owners understand they will most likely have to pay for repairs/corrections. We are looking for an estimate/report on what is needed before the house goes under contract and a home inspection is done.
