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 cracksuneven floorsmusty 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 waterproofingfoundation, 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.

We’ve had some basement flooding issues over the years. In 2023 we hired Groundworks to assist with the mitigation. We just had our 1 year preventive maintenance. Josh Moreno was our inspector. He was polite, thorough, and knowledgeable about our systems in place. He tested everything and walked us through the process as he did it. We’re pleased with Groundworks and Josh!

Ernest, Shahid, and Greyson worked diligently to stabilize our foundation. They were great at communicating arrival times and explaining the process as they went along. They were polite and considerate of our property while installing the 12 Push Piers needed to stabilize and raise our settling foundation. We would highly recommend this crew and their extra helpers who jumped in at times during the project.

I had a great experience from start to finish! Aaron Hudson and Christian Mayfield were professional, knowledgeable, and took the time to explain the entire concrete lifting and repair process. They showed up on time, paid attention to the details, and made sure everything was done right. The finished work exceeded my expectations, and the concrete looks and functions so much better. It’s clear they take pride in their work and genuinely care about their customers. I highly recommend Aaron, Christian, and the entire team to anyone needing concrete lifting or repair!

Groundworks – we were so skeptical. Had so many questions and then tried to resolve the matter on our own (by slanting adjacent soils away from the house). However, our house new (15-18 years old) extension kept sinking. So for us we ordered screw jacks. It’s still too new to know how well this will work but we do know Doors are already easier to operate The warranty is lifelong on the house And, the crew that installed it could in been more professional nor caring if our property. Big shout out to the foreman Silvino Hernandez and his amazing crew Alvin, Jorge, Antonio and Roberto. Thank you for easing our minds that this was the right direction for us.

Overall great experience. Kalen was incredibly thorough in his inspection process and provided multiple options for addressing our crawl space issues. When we selected the best option to help protect the health of my immunocompromised wife, the contract process was both detailed and quick. Communication was great through the whole process. Our installation team of Francisco, Salvador and Rene were on time, thorough, clean and made sure they never disrupted our daily routine. We were very impressed by their professionalism and made sure we had the opportunity to inspect work on a daily basis to make sure it met our expectations. Great experience and includes a solid warranty. Overall a great experience!

We're extremely happy with the work Groundworks' foreman, Francisco, and his associates, Rene and Jose, performed for us. The company was extremely proactive and responsive. They obtained our permit very quickly and subsequently performed the service sooner than expected. The crew, Francisco, Rene, and Jose, arrived early, performed the work with care, cleaned up impeccably, and even left our property in better shape than they found it, fully relaying a brick utility pad that had been half removed due to a previous project. Their lifetime guarantee for the work will fully transfer to future owners, and they come out once a year to maintain quality assurance. I will happily recommend Groundworks to anyone I meet in the future who may need foundation stabilization. Thank you Groundworks for your time and attention to our project!
