Parking Structure & Deck Waterproofing in Bakersfield, CA

The primary reference standards are IBC Section 1807 (waterproofing and dampproofing of foundations and below-grade structures), ASTM C836 (high-solids content cold-liquid applied elastomeric waterproofing), and ASTM C1770 (traffic-bearing waterproofing systems). For parking decks above occupied space, local jurisdictions may impose additional requirements beyond minimum code - confirm the specific requirements with the Bakersfield building department during permit application. We include code compliance documentation in our permit submittals as a standard practice.

ADA documentation at parking deck closeout includes: slip resistance test results (ASTM C1028) at all ADA-designated accessible spaces, accessible routes, and ramp surfaces; photographic documentation of accessible space striping restoration after membrane work; and confirmation that curb cuts, accessible route transitions, and signage were restored to pre-construction condition or improved. The slip resistance test report is included in the project closeout package and is available for ADA compliance file.

Concrete grinding and scarifying operations require dust containment - typically wet grinding methods or vacuum-assisted dry grinding that captures dust at the source. If asbestos-containing materials were used in the original deck construction (pre-1980 structures), abatement documentation is required before waterproofing can proceed. Solvent-containing primers and adhesives are applied in compliance with CA's VOC limits. All waste materials are disposed of in compliance with CA's solid waste regulations, with disposal manifests provided at closeout.

A building permit is typically required for parking deck waterproofing in Bakersfield when the work involves concrete removal (structural repair), drain replacement, or expansion joint reconstruction. Pure membrane replacement on a structurally sound deck may qualify as a maintenance repair in some jurisdictions - confirm with the building department before assuming no permit is required. Permitted work requires inspection at substrate preparation (before membrane application), pre-cover (before topcoat), and final (completed and cured). We manage the permit application and inspection scheduling as part of our standard pre-construction process.

Polyurethane and MMA waterproofing materials used in enclosed parking structures are required to meet fire code requirements for materials installed in parking garages - typically Class A flame spread rating. Primer and adhesive products used in enclosed or semi-enclosed structures must have VOC content and flame spread characteristics acceptable for use in occupied garages per NFPA 88A (Standard for Parking Structures). We specify only products with compliant fire code ratings for garage-type occupancy and provide product data sheets confirming compliance with the permit submittal.
