Permeable Resin Paving Questions

In most residential applications, yes. An open aggregate matrix drains stormwater through the surface layer itself, meeting SUDS-compliant requirements without separate soakaways or attenuation tanks. The written project scope confirms the drainage design for your specific site before work starts.

The contractor assesses sub-base permeability during the site inspection. If the existing base blocks drainage, the scope will specify the remediation needed, whether that is a new open-graded sub-base or a different drainage path, before any resin is laid.

UV-stable aggregate specified for high-altitude conditions resists both freeze-thaw expansion and Front Range sun. The material specification in your written scope names the aggregate grade selected for your site’s exposure.

Impermeable surfaces concentrate runoff, which can trigger drainage conditions on new builds or major renovations under Boulder County rules. Delaying replacement risks a formal drainage condition being attached to your next permit, adding cost and complexity to the project.

We follow up after the surface is laid to confirm drainage performance matches the rate stated in the written specification. If there is a shortfall, it is identified and addressed before the job is closed out.

Yes. Boulder County SUDS requirements apply to car parks and large paved areas as well as residential driveways. We connect you with contractors who have specified permeable resin-bound surfaces for both residential and commercial sites in the area.
