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 were lucky to work with Kalen for our quote to prevent further foundation damage in our 1960s home. He was very helpful in answering our questions, providing an overview of what was going on with our foundation, and various options for addressing the issues. Jesus Sanchez and Jose Ramirez came to execute the first half of the job and they were respectful, knowledgeable, and left our home clean. Great experience so far!

On Friday, Jon and Seth came out to lift the driveway. These guys are awesome! Very professional and knowledgeable about their work. Explained to me what was going to happen and answered all my questions. This morning, Jayden, Caitlyn and Mandi came out to seal the cracks on the driveway. It was great seeing an all female team. They explained what they were going to be doing and answered all my questions. They are very professional and knowledgeable about their work. Thanks Groundworks! Mary Pool

Thank you to Aaron Kanter, Groundworks Service Technician for recently doing the annual inspection of the foundational work and crawl space liner encapsulation that was previously done at my home. I am incredibly pleased with the level of support Aaron provided to me during the service. Aaron took baseline readings of my home's main floor that will be used in future annual inspections to more precisely measure whether any shifting or movement occurs. Aaron was thorough in his overall evaluation, answered my questions, and provided suggestions as to how Groundworks may be able to help remediate other problems that I described to him. I will definitely request Aaron for future service inspections as well as for any additional work that I take on. Thank you, Aaron and Groundworks. 5 stars for both!

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.

Groundworks sent an excellent crew headed by Gabriel Amaya with Juan, Mauro and John. Their first action was to ensure the work area of the basement would be dust free by enclosing the area with plastic. They were familiar with the bentonite clay soils below and had proper equipment to install new pile foundations and the two columns for support of the upper floor. I was impressed with Groundworks' versatility in handling the adverse soil conditions and their neat work habits.

Big project in our basement, and it couldn’t have gone better! Luis, Ramon, and Rodrigo are experts at what they do and are true professionals! Installing 2 sump pumps, a water barrier, cutting a trench in the concrete for a French drain, and burying the exit pipe outside to make it as indiscreet as possible in the front of our historic home. Their communication throughout the entire project was excellent- they filled us in on and showed us what they were doing every step of the way. They treated our home like it was their own, taking extra time to make sure the work looks excellent, cleaning up after themselves, and even going the extra mile to blow all of the leaves off of the sidewalk in front of our house to not track them in! We couldn’t recommend Luis and his crew enough!
