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.

Luis, Ramon, and Rodrigo were amazing! The work they completed looks great and the crew were hard working, detailed orientated, and very respectful! Luis went above and beyond to explain about the work being done and what each installed feature did. He was very helpful in explaining how to take care of the french drain, sup pump, and wall braces going forward. 5 out of 5 stars!

We have been a customer of Rod Martin and now Groundworks for several years. Our initial Fun started with a complete encapsulation of our crawl space and installation of sump pump. Later work included wall anchors, a basement perimeter drain and installation of additional drain pipe under a new basement pad. Big expense over the years but results have been extremely positive!! Annual service has been great. Today, due to a prior job going longer than expected, our serviceman Mike was delayed. Instead of having to re-schedule, Matt Davidson came out to perform the work on his way home. We really appreciated his timeliness, thoroughness and explanations. Ground Works should be proud of Matt's involvement and expertise.
