Resin Steps & Entries Questions

Resin-bound aggregate flexes slightly under freeze-thaw stress rather than fracturing. The key is confirmed sub-base depth before installation. A shallow or poorly compacted base is what causes heave, the written scope locks in the preparation standard before any material is mixed.

The open resin matrix embeds aggregate across the full tread width, producing a textured surface similar to fine gravel. It outperforms smooth concrete or pavers in wet conditions. For entries with heavy ice exposure, the contractor can specify a coarser aggregate grade in the written scope.

A cracked nosing collects water in the gap. Each freeze cycle widens the crack and can undermine the step’s structural bond to the riser. What starts as a surface repair becomes a full step replacement, and a trip hazard in the meantime.

Yes, if the concrete substrate is structurally sound and free of active movement. The contractor assesses the existing surface during the site inspection and notes any remediation required in the written scope. Resin applied over a failing substrate will delaminate regardless of binder quality.

Most resin-bound installations cure to foot traffic within 24 hours, depending on temperature and humidity. The contractor confirms the cure window in the written scope. Cold weather below 40 degrees Fahrenheit slows the binder cure and may require scheduling adjustments.

Resurfacing existing steps typically does not require a permit in Boulder. Structural changes to step height, width, or the supporting base may trigger a review under Boulder’s building code. The contractor confirms permit requirements during the site inspection before work begins.
