Bentonite, Bedrock and Foundation Damage in Colorado

olshan man crawl space repairColorado is known for its volatile, expansive bentonite clay. When coupled with an arid climate and occasional floods or snow, it creates soil conditions that leave many Colorado homes vulnerable to foundation damage. This happens because an increase in subsurface moisture can lead to swelling, and a decrease in subsurface moisture can lead to shrinking.

It’s important to assess signs of foundation problems such as; cracks in walls, floors that sag or a wet crawl space, early, before the damage spreads. Fortunately, our team of Denver foundation repair experts are here to help. Our team includes a Structural Engineer on staff, available to provide you with a free, no-obligation foundation assessment and custom repair plan.

One of our Certified Structural Technicians will inspect your home and provide you with a detailed job assessment and quote. About 20% of the homes we inspect do not require repairs. In those instances we will be glad to provide you with a foundation maintenance program that can help mitigate future problems.

We also work hand-in-hand with 3rd party Structural Engineers to execute repair plans of all sizes, for both residential homeowners and commercial business owners. If you already have a repair plan, let us complete the project on time and on budget.

Crawl Space Encapsulation & Structural Repair

About 35% of the homes we visit in Colorado have crawl space foundations. Like basement homes, crawl spaces like the pier and beam foundation are susceptible to both structural, water and air quality problems. Common signs of crawl space problems include; sagging floors, cracks in walls or doors that stick and musty odors.

To address structural issues we offer:

To treat air quality problems in crawl space homes we offer crawl space encapsulation.

Due to the process known as the stack effect, much of the air you breath inside your home comes directly from the crawl space. For homes with wet crawl spaces, this usually results in a dank smell throughout the house. To remedy this we provide drainage solutions designed to keep water out and away from the foundation as well as crawl space encapsulation.

Crawl Space EncapsulationSafeSeal™ Indoor Air Quality control, using Moisture Barriers, water-resistant liner, and a Dehumidifier or Air Exchange System.

Concrete Driveway, Sidewalk and Flatwork Repair

repaired sidewalkPeriods of flooding or snow followed by dry heat can result in soil erosion. This never-ending cycle does a number on the concrete work here in Colorado, as evidenced by this recent article on local sidewalk damage. As the soil erodes, gaps between the dirt and concrete form, resulting in things like cracked sidewalks, heaving driveways or uneven patios.

A sunken driveway, sidewalk or sunroom is more than just eyesore, it’s a safety hazard! The good news is expensive concrete replacement can usually be avoided.

To repair sunken concrete, we offer PolyLift™. This 2-part environmentally safe compound is injected underneath the surface to fill voids and gaps between the structure and soil. The sunken concrete is gently lifted and restored to an acceptable level.

PolyLift™ is gentle, quick, easy and clean. If you’re looking to repair sunken or cracked concrete in as little as 1-day, click here to learn more about PolyLift™.

Repairing Concrete Slab Foundations

To repair foundation damage for homes with slab foundations, we offer a variety of effective repair methods. Our most popular repair plan utilizes the Cable Lock ST Plus system. This system includes the greatest aspects of steel pilings with the greatest aspects of concrete pilings to achieve a deeper, more secure repair.

The system is driven deep underneath the home, lifting the sunken foundation and leveling it to as close to the original build as allowable.

Since each home and landscape is different, our custom repair plans may call for other methods of repair, such as; helical piers, bell bottom piers, steel piers or pressed pilings. Here is a quick overview of the different piling types that are commonly used to repair foundations:

Alternatively, PolyLift (a more effective alternative to mudjacking) is sometimes recommended to fill voids in the soil and lift the foundation to an acceptable state.

Did a very professional job waterproofing the basement. When issues came up during the 100 year flood, came back and did additional work free of charge, as a part of their warranty. While their original waterproofing system turned out not to be sufficient to deal with that major flood, it kept our basement dry for 8 years before that. Before the original system was installed, the basement used to flood twice a year.
