What Goes Wrong

Where permeable paving fails, and how to avoid it

Wrong Sub-Base

A compacted, impermeable sub-base blocks drainage entirely, making the permeable surface above it useless.

Sub-Base Confirmed First

The contractor verifies sub-base permeability and fall in the written scope before installation begins.

Unverified Drainage Rate

Installing without calculating the site’s actual drainage rate risks failing Boulder County SUDS conditions on inspection.

Drainage Rate in Writing

The written project scope states the drainage rate and confirms it meets the site’s stormwater requirements.

UV & Freeze Damage

Standard aggregate fades and fractures under Front Range UV exposure and repeated freeze-thaw cycles, voiding the drainage function.

UV-Stable Aggregate

UV-stable stone specified for high-altitude sun and freeze-thaw cycles keeps the open matrix intact and draining season after season.

No Post-Install Check

Without a follow-up, a drainage shortfall goes undetected until standing water or a county notice forces a costly fix.

Follow-Up Confirmation

We follow up after installation to confirm drainage performance matches the written specification before the job is closed out.

SUDS Drainage

Permeable resin paving that meets Boulder County drainage requirements

Stormwater runoff from impermeable surfaces is a planning and flooding issue, permeable resin paving resolves it through the surface material itself.

Request a Scope

The drainage mechanism in permeable resin paving is the open aggregate matrix: water passes through the voids between stone particles rather than running off the surface. The contractor confirms sub-base permeability and fall in the written project scope, ensuring the drainage rate meets the site’s stormwater requirements before installation begins.

Boulder County SUDS-compliant drainage requirements apply to driveways, car parks, and large paved areas. A permeable resin-bound surface satisfies those requirements without adding soakaways, channels, or attenuation tanks in most residential applications. The written scope confirms the drainage design for your specific site conditions.

UV-stable aggregate maintains surface integrity and color through Front Range freeze-thaw cycles and high-altitude sun. The scope covers experience specifying permeable resin paving for both residential and commercial Boulder sites. We follow up after installation to confirm drainage performance matches the written specification.

Common Questions

Questions about permeable resin paving in Boulder

  • Does permeable resin paving actually satisfy Boulder County SUDS requirements?

    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.

  • What happens if the sub-base is already impermeable?

    Sub-base permeability is assessed during the site inspection. If the existing base blocks drainage, the scope specifies the remediation needed, whether that is a new open-graded sub-base or a different drainage path, before any resin is laid.

  • Will the surface hold up through Boulder’s freeze-thaw cycles?

    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.

  • What happens if I delay replacing a cracked or impermeable driveway?

    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.

  • How do I know the drainage will perform as promised after installation?

    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.

  • Can permeable resin paving be used for commercial car parks as well as driveways?

    Yes. Boulder County SUDS requirements apply to car parks and large paved areas as well as residential driveways. Every scope covers permeable resin-bound surfaces specified for both residential and commercial sites in the area.
