Patio Repair & Resurfacing in Evans, CO

Residential patios in Evans are typically rear-yard slabs poured when the home was built — often in the late 1970s through the 1990s, when mix designs and site preparation standards were less consistent than today. Many of these slabs were poured without an adequate expansion gap at the house foundation, and decades of thermal movement have created a stress fracture along that transition. Others settled when the clay soils beneath them dried out during drought years, leaving one or more sections lower than the adjacent portion and creating drainage toward the house rather than away from it. Summer entertainment on an Evans patio involves outdoor grills, furniture, planters, and heavy pots that concentrate loads on slabs not always designed for that use. When those loads fall on a slab section that is bridging a void in the subbase — caused by clay shrinkage during dry summers — cracking is the predictable result. The intense summer sun at Weld County's elevation also bleaches unprotected concrete surfaces to a washed-out gray and promotes surface dusting as the cement paste carbonates and erodes.

One of the most common structural problems we find on Evans patios is a failed or missing expansion joint where the patio slab meets the house foundation. When this joint isn't properly installed or maintained, the patio slab and the foundation press against each other through thermal expansion cycles, and one of two things happens: the concrete spalls and cracks at the contact point, or the slab pushes against the foundation and contributes to pressure on the structure. Neither is trivial. During patio repair work, we always address this joint — routing out the failed material, installing a proper closed-cell backer rod, and filling with a flexible polyurethane sealant rated for Colorado conditions. This is not an upsell item; it's a structural element of the patio that should be part of any complete repair. Ignoring it and simply resurfacing over the problem area leads to cracking at the same location within a year or two.

We've worked on patios throughout the Greeley-Evans area and bring specific knowledge of how these slabs have aged in Weld County conditions. Most patio jobs are completed in a day or two and don't require you to be home throughout.
