Patio Repair & Resurfacing in Como, CO

Como patios are often attached to cabins, vacation properties, or full-time mountain homes that see heavy outdoor use during a compressed summer window. Many of these patios were poured without the freeze-thaw-rated concrete mix designs and protective sealers that the elevation demands, and they show the results: pop-outs, surface spalling, wide control joint gaps, and the sunken or heaved panels that come from active soil movement below the slab. The expansive clay soils beneath many Park County properties are the root cause of more patio damage than any other single factor. A patio slab poured directly on grade without adequate compacted base course sits on soil that swells each spring as snowmelt saturates the ground. The result is a patio that looks level in July and has a two-inch differential by October. When that heave is localized — occurring under one panel but not an adjacent one — the concrete cracks along the stress concentration. These cracks let water in, the water freezes, and what started as a clean construction crack becomes a fractured, scaled edge within a few seasons.

Patio repair with Concrete Doctor begins with a site assessment focused on understanding what's causing the damage, not just documenting what it looks like. We probe beneath slab edges to check for voids, assess crack patterns to determine whether they're from thermal movement, soil heave, or subgrade washout, and evaluate whether the overall slab geometry is still close enough to level to be a viable resurfacing candidate. For patios where resurfacing is appropriate, we use polymer-modified overlays applied over a properly prepared surface. The preparation stage — grinding or scarifying the surface to remove scale and create mechanical bond profile, routing and filling cracks, and applying a bonding agent — accounts for a significant portion of the project time and is what makes the difference between an overlay that holds for 20 years and one that delaminates in its second winter. For more significantly damaged or settled patios, we may combine panel repair or edge rebuilding with the overlay application. Finished surfaces can be broom-textured for slip resistance, stamped for decorative character, or sealed with a UV-stable topcoat.

The most common patio repair request we get from mountain Colorado properties is addressing differential settlement — where one panel of a patio has heaved or dropped relative to its neighbor, creating an edge that catches a foot. In Como's soil conditions, these elevation changes can happen surprisingly quickly, particularly in years with heavy snowpack followed by a dry summer that dries and contracts the ground beneath the slab. Depending on the severity and whether the movement has stabilized, options range from grinding the raised edge smooth, to filling and capping the low side with an overlay, to panel replacement if the concrete has fractured beyond repair. We assess whether the soil movement is ongoing or has reached a new equilibrium — ongoing movement needs to be addressed at the subgrade before surface work can succeed. This is a distinction between a repair that lasts and one that requires the same intervention every few years.

A patio in Como needs to handle snowmelt runoff as well as rain, and surface texture is part of how that works safely. A patio that pitches toward the house, lacks proper slope away from the structure, or has a slick sealed surface creates both drainage and slip problems in a climate that cycles between wet and icy conditions repeatedly each season. When we resurface a patio, we confirm the slope and address any areas where the finished overlay surface will pool water. Texture options for resurfaced patios include broom finishes for consistent non-slip character, exposed aggregate for a more natural mountain aesthetic, and light stamp patterns that add visual interest without sacrificing the functional surface quality. The topcoat sealer — if one is used — is selected for UV resistance and for maintaining traction when wet, not just for sheen. At Como's elevation, a glossy wet patio surface is a genuine hazard from May through October and we don't install finishes that create that condition.
