Groundworks Provides Professional Foundation and Crawl Space Repair

As the most populated city in Colorado, Denver homeowners deal with their share of foundation, waterproofing, and crawl space problems. If your home is experiencing foundation cracks, uneven floors, musty odors, or sunken concrete slabs, it’s likely the area’s soil and weather conditions are to blame.

Homes, both big and small, new and old, experience problems regardless of foundation type. The soil in Denver is poorly drained clay loam. This is one of the most problematic soil types for foundation construction. Clay soils absorb and hold water, causing molecules to expand. This added water content puts pressure on basement and crawl space walls, causing them to crack and bow inward. During dry periods, which are common since the area sees less than average rainfall per year, the clay loam soil shrinks, leaving voids that are unable to support a home. A sinking foundation leads to cracks and sloping floors throughout your home. Additionally, cracks provide the perfect entry point for water and cause costly damage. 

Groundworks offers various waterproofing, foundation, and crawl space repair options. Our innovative, permanent solutions are backed by long-term transferable warranties for peace of mind. With more than 20 years of living and working in the Denver area, you can trust we aren’t going anywhere and will be there if you need us. Let one of our trained inspectors walk you through our custom solutions to solve your home’s unique problems.

Mike Gold came out to do my yearly inspection. He was courteous and personable, and listened patiently as I identified some areas of concern. He then explained what the inspection process entailed. When he finished, he sat with me and explained the results, even going so far as to compare them to last year’s results and the results from 2018. His taking the time to do this reassured me that my foundation was in good shape. I very much appreciated Mike and recommend him (and Groundworks) without reservation.

We had piers put in over the last couple days. The inspectors (monitored our home over a couple years prior to beginning work) Ryan L. and Anthony G. took their time doing detailed and thorough inspections, then explained their data and discussed options with us. Our pier project crew was excellent. Jake was very informative and professional in leading the project. Omar and Juan did a great job with precision work and left the site tidy. Couldn't have asked for a better experience. Thanks!

Nick stopped by today and was super helpful in looking at my crawl space and the basement of my house. In the end, their services did not make sense for this particular issue but I thought it was incredibly professional that he did not try and "sell me" something for the sake of doing so. Would absolutely use and recommend for their specific services! Timely and prompt too!

Just had Jeff S. walk me through water proofing of our basement, after some horrible experiences with other companies I feel confident and educated about what needs to be done. I appreciated Jeff’s excellent communication and calm and compassionate explanation of what seemed like a nightmare problem. Looking forward to working with Groundworks!

Andrew and Robert came out to insert a crossbeam. They were efficient and professional- explaining everything step by step. They took care to check in w us re the progress and the final pressure exerted on the beams. Couldn’t asked for a better team. For us, it did not totally take away the vibration but that was not due to their work. Most likely needed more than one cross beam so the engineer who reviewed the plans sh hv given us a call. Again the team was great.

My inspector, Curtis, was knowledgeable and explained the issue I was having in a way that I could understand. Luis, Ramon, and KeVaughn did an amazing job with installing my basement solution.

Groundworks is an extremely professional organization and delivers a quality product as well as customer service. We had our crawl space encapsulated. The person (Kalen) who came to review the product and installation was professional, knowledgeable and reviewed their product without pressure. The crew who came to do the work (Aaron, Elijah, Carlos) were all efficient, friendly, and great at communicating their progress. They did an outstanding job. Groundworks also sent a person to do a site checkup while the crew was working. An overall great experience.
