Permeable Resin Paving in Boulder
Permeable resin paving uses UV-stable polyurethane resin mixed with 3-6mm stone aggregate to create water-infiltrating surfaces that meet Boulder County SUDS drainage codes. Driveways, parking areas, and walkways allow rainwater and snowmelt to pass through the surface into engineered sub-base layers, eliminating runoff pooling that triggers city violations.
Installation includes permeability testing to confirm infiltration rates meet strict Boulder regulations, plus documentation for permit compliance. The resin bound system handles vehicle loads while managing water flow through a 50mm permeable base layer over compacted aggregate.
Frost-resistant formulations survive 20+ Front Range freeze-thaw cycles without cracking or heaving. Surfaces resist UV degradation from high-altitude sun exposure and require no resealing, though periodic pressure washing clears debris from aggregate pores to maintain drainage performance.
