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.

Kalen, Certified Field Inspector, came to our house for a foundation inspection. Denver had snow the night before and he was still on time. He was very friendly and knowledgeable and was detail in explaining everything. My husband and I appreciate Kalen's expertise so much and recommend to contact Groundswork for your home foundation concerns.

Our garage was too high in the middle, so Groundworks lifted it so the door could close properly. They also filled under our porch & driveway so it will not sink. Great job. Mike Wrenn & Benita Algiene were excellent at support and going the extra mile. Thanks

Groundworks Field Inspector Mike Gold was excellent in communicating with us the results of his work/measurements on our property. He explained that we now have a baseline for comparison in future years re: our house's foundation settling. He also informed us about the effect of moisture content of soil below the foundation and how to mitigate the potential problem. He is indeed knowledgeable in his area of expertise and has excellent communication skills!

I recently contacted Groundwork for an estimate and subsequently contracted with them to have my front porch lifted, my driveway leveled, and my crawlspace encapsulated. The estimate process was thorough and scheduling was prompt. The work was completed on time without any surprises. I felt the price was fair for the job done. Andres Martinez and Mariano Padilla did a great job—efficient, professional and knowledgeable.

You never know if a big company is just telling you what you want to hear. When your house is starting to fall apart, big ticket items like fixing your foundation is scary. For a moment, we weren’t sure if we went with the right company. And then Jeremy Elston showed up. It felt like the first time someone was telling us the truth and not scamming us. He was so incredibly thorough and respectful of our home. He took his time and explained to us what he was doing and why. Foundation repairs aren’t always one and done. When the time came to make some adjustments, Jeremy was back and walking us through next steps. We feel confident in the work done and its impact to our home. I’m not exaggerating when I say I’ve actually stopped having nightmares about the house falling apart. Every professional needs to take a page out of Jeremy’s book.

We hired Groundworks to encapsulate our crawlspace and Aaron and Howdy did a fantastic job. Even with being a man down, they still got the job done on time, and took the time to review the space when it was completed with us. The before and after is incredible and we are very happy with their work and communication!!
