The front porch of this Longmont, CO home was starting to sink. The homeowners noticed a drastic separation of the left pillar from the cement. This was a major concern, as the pillar requires stabilization to support the overhang properly. The PolyLevel crew, led by Jacob, used our specialized injection methods to raise the slab back up to a safe height and level out the pillar again. The porch is now stable and the homeowners can rest assured they won't have to worry about any collapses!

Raise your Concrete Slab with PolyLevel™ in Greater Denver

Is your concrete slab shifting due to a weak soil base underneath your home? When your home's surfaces are not level, you are exposing your family to a falling hazard and reducing the overall image of your home. 

Calling another contractor will lead them to treat your concrete slab with a generic slabjacking or mudjacking. This would involve a contactor smashing your slab, leaving you with a messy yard and a distracting job.

The PolyLevel® solution from Rod Martin's Complete Basement Systems is cleaner, more thorough and stress-free. One of our trusted technicians will drill holes into the slab, inject a polymer solid that will fill the space beneath it, which will ultimately raise and level it.

Also, Rod Martin's Complete Basement Systems now offers the ideal concrete sealing solution: SealantPro. After just one application, SealantPro will triple the lifespan of your concrete, shielding it against the elements. Protect your concrete from damage and stains for years to come with SealantPro.

Job Stories From Longmont, CO
Longmont, CO PolyLEVEL

A home in Longmont, CO was in need of concrete leveling and crack repairs. The homeowners wanted their garage to be crack-free and the porch to be leveled. They had heard many great reviews about Rod Martin's Complete Basement Systems concrete repair jobs and wanted only the best to work on their home. After getting their free estimate, the homeowners were very comfortable with the plan. 

Our experienced foreman Jacob and his installation team were ready for the opportunity to help these homeowners out. In order to give the homeowners the best results, the team made sure to use the best products. To level the porch PolyLEVEL 250h was injected underneath the concrete so that the foam leveling product would rise up and make the slabs even with one another. Next to fix the cracks in the garage, NexusPro Joint Sealant was used to seal the cracks back together like a gel glue. 

After Rod Martin's Complete Basement Systems left the job, the homeowners were excited to start using their concrete space again! 

Longmont Concrete Repair

Trey of Longmont, CO was in the market to get his concrete driveway and front walk-up entrance repaired. He was experiencing displeasure because every time he drove up to his home he would only look at the cracks. Wanting to achieve peace of mind when he comes home from work, Trey decided to find a contractor that he could trust to help him out. After being referred by a neighbor, he scheduled his project with Rod Martin's Complete Basement Systems. 

Jacob, our expert foreman, and his installation team discussed with design specialists about how they were going to relieve Trey's stress. The team decided on the right course of action and set out on the job. First to level out the concrete slabs and walk-up, a foam leveling product was injected underneath the slabs. Once the foam is injected it rises up the concrete up, making the slabs level with one another. After the leveling was complete, to seal the deal the installation crew filled in the cracks with a joint sealant. Once the project was finished, the exterior of the home look great once again!

Rod Martin's Complete Basement Systems was happy to help Trey achieve a high quality of life at his home.

Experienced Crew & Quality Products Repair Cracked Crawl Space Wall in Longmont, CO

Even though the crawl space under a home isn’t a part of the home that we spend a lot of time in, it’s a part of the house that can make a big difference in the safety and health of the rest of the home. David H. was surprised to find a crack in the wall of his Longmont home’s crawl space. Not wanting to take the chance of it getting worse, David immediately looked up local foundation contractors and after reading reviews from happy customers, decided to give Complete Basement Systems of CO a call.

After showing foundation expert Rick Donohoe the problem, Rick assured David that this was something that could be effectively repaired using the company’s quality products installed by their experienced contractors. Alejandro Limones and his crew got to work and began installing push piers to help stabilize the foundation. They also repaired the cracks. David couldn’t have been happier with the results. So happy in fact, that he contacted the company again to reduce radon levels in his crawl space. The crew installed CleanSpace vapor barrier and SilverGlo wall insulation to prevent radon from entering the home and to keep levels at a safer amount.

Our crawl space has several piers running down the middle of the house. Two of those are near a pit dug to fit a water heater and boiler. The dirt has been falling away from those piers into the pit and they now need to be repaired. A structural engineer recommended we extend the piers below the depth of the pit.

I have a small house (1008 Sq ft) built in 1979. It is a modular built in a nearby factory and placed on the site. Over time, the center of the house has begun to sag and needs to be jacked up. This is apparently a common problem in the neighborhood, more so in larger homes and in homes with more people living there. 4B's said they would do the interior detail work, but were reluctant to do the initial lifting of the floor. If you do such work, I would like to get an estimate. Thanks so much.

We live in a townhome complex, and we've begun to notice that almost every other house on the block has their sump pump go off regularly every day. You can see them discharge into the common grounds. But I've never once seen our sump pump discharge on its own. I've tested the sump pump itself, by pouring water into the well and it will pump that water out, so I know that it the sump pump works, but I'm concerned that the pit might have been installed incorrectly and doesn't collect any water. Is there any way to investigate the sump pit and see if it was installed properly?

Hi - I recently discovered wet carpet in my basement. I tore out the carpet along the wall and then removed about a foot of the drywall along the wall. I found some mold and the carpet tack strips were black and rotting. It seems like the water is seeping in along the perimeter of the base of the wall. I cleaned and dried it all out but overnight a small amount of water had seeped back onto the floor in a few areas. We have had 2 big rain storms this month but it hasn't rained at my house in 8 days. I need some help solving this problem! Thanks, Judd Nutting
