How Bentonite Clay Damages Grand Junction Foundations
Why Western Slope Homes Experience Foundation Shifts, Cracks, and Crawl Space Failure
Grand Junction and the surrounding Grand Valley (including Fruita, Clifton and Palisade) are famous for beautiful landscapes, but local homeowners face a hidden structural threat: highly expensive bentonite clay soil. Common north of I-70 and near the Colorado Riverbend, this unique soil behaves exactly like a sponge. When winter snow melts or heavy desert storms hit the clay absorbs moisture and expands with immense hydraulic pressure.
In spring and summer, moisture causes the clay to expand, pushing aggressively against concrete basement walls and slab foundations. In the dry fall and winter months, the soil shrinks drastically. This continuous expansion and contraction cycle causes foundations to settle unevenly, walls to crack and crawl spaces to shift completely out of alignment.
Warning Signs of Bentonite Soil Damage in Mesa County:
Sticking door and windows that won’t close smoothly in the summer months.
Stair-step cracks appearing in exterior brickwork or interior dry wall.
Cracked, unlevel or sloping concrete floors in your basement or garage.
Gaps opening up between your walls and celling or floor.
