Traffic Membranes for Decks That Stay Open
Our crews work occupied office, medical, mixed-use and residential garages, phasing every section around tenants and business hours so the rest of the deck keeps parking cars. Backed by 12 years in business and our 2-year workmanship warranty, we have delivered over 1,187 projects, and owner and manager references are available on request.
From the deck survey and crack mapping to the membrane, the wear coat and the restriped stalls, our team handles the parts of a deck job that decide whether it finishes on schedule. Serving Riverside and neighboring Diamond Bar, Yorba Linda and Claremont, we keep to the owner's schedule, work nights and weekends when the garage is quietest, and reopen each section restriped and ready for traffic.
Request a bid with your deck size, level count and the hours your garage can close a section, and we will walk the structure with you.

Why Parking Decks Need a Membrane
On an elevated deck the coating is waterproofing for the structure, not just a wear surface, because every crack that lets water through also lets it reach the reinforcing steel inside the slab. Water that drips onto cars below is the symptom the tenants notice; rust and spalling in the concrete is the damage the owner pays for later. Sharon's deck near the Mission Inn showed the first stage: an upper deck section with cracks letting water through onto the cars parked below. A traffic-bearing membrane seals the top of the slab so rainwater and washdown run to the drains instead of into the structure.
Cracks, Joints and the Slab First
Every active crack and expansion joint is routed and sealed before the membrane, because a deck coating that bridges an open crack splits right over it. We map every crack on the deck, rout the active ones, fill them with a flexible sealant, and detail expansion joints, drains, curbs and column bases so the membrane runs continuous across them. Spalled spots on San Antonio Heights and Villa Park decks get patched flush, and the whole field is ground to a CSP 2 to CSP 3 profile so the membrane grips sound concrete. Decks in Diamond Bar and Yorba Linda office parks often need more joint work than field work.
Traffic Membrane Systems and Wear Layers
A traffic membrane is a layered system: a primer, a flexible waterproofing base coat, then a harder wear coat with aggregate broadcast into it. The base stays soft enough to bridge hairline movement on El Sobrante and Woodcrest podiums, while the wear coat takes tires, turning wheels and foot traffic. Ramps, turns and entry lanes get a heavier aggregate load, since that is where tires scrub hardest. Open top decks get a UV-stable aliphatic topcoat that will not amber or chalk in the sun, while covered levels can use a lower-cost topcoat where no sun reaches.
Deck Coating Specifications
- Surface prep
- Mechanical diamond grinding to a CSP 2 to CSP 3 profile on every floor, never acid etching
- Dry film thickness
- 15 to 35 mils on a multi-coat flake system, 40 to 120 mils on high-build and self-leveling floors
- Basecoat solids
- 80% to 100% solids by volume, so the coat does not shrink thin as it cures
- Topcoat
- UV-stable aliphatic polyaspartic clear coat that will not amber in the sun through an open garage door
- Moisture testing
- Every slab tested; above 3 lbs per 1,000 sq ft per 24 hours it gets a moisture-mitigating epoxy primer
- Hot-tire resistance
- Rated for tire contact heat from 140°F to 180°F
- Slip resistance
- 0.60 to 0.85 DCOF with aluminum oxide or polymer grit in the clear coat
- Hardness
- 75 to 85 Shore D, so a dropped wrench or a jack stand does not gouge it
- Compressive strength
- 8,000 to 12,000 PSI, well above the 3,000 to 4,000 PSI of the slab underneath
- VOC content
- 0 to 50 g/L, inside South Coast AQMD limits
- Walk-on time
- 4 to 8 hours on polyaspartic, 18 to 24 hours on 100% solids epoxy
- Park-on time
- 24 to 36 hours on polyaspartic, 72 to 96 hours on 100% solids epoxy

Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Parking deck coatings are typically budgeted per section, at an estimated $5,500 to $14,000 for each 1,000 to 2,000 sq ft, and crack and joint footage, membrane thickness and the aggregate load on ramps move the price most. Sharon's upper deck section of about 1,900 sq ft came in at an estimated $9,800 to $13,900 with crack routing included, and a two-section run typically lands at an estimated $14,000 to $24,000.
| Job type | Est. investment | Est. duration on site |
|---|---|---|
| Commercial or multi-car facility floor | Est. $5,500 to $14,000 per section (1,000 to 2,000 sq ft) | Est. 3 to 5 days |
| Upper deck section, traffic membrane with wear coat | Est. $9,800 to $13,900 | Est. 3 to 5 days |
| Two-section deck run, phased | Est. $14,000 to $24,000 | Est. 3 to 5 days per section |
Deck figures here are budgetary estimates and are subject to change. Your written quote, confirmed on bid after the deck survey and the crack map, sets the final price and the closure schedule, and it depends on the square footage, the crack and joint footage and how many sections the garage can close at once.

An upper deck section with cracks letting water through onto the cars parked below
Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Sharon manages a building in the Mission Inn district of Riverside, where an upper deck section with cracks letting water through onto the cars parked below had tenants complaining. We recommended routing and sealing the cracks, then a traffic membrane with an aggregate wear coat, closed one section at a time. The upper parking deck section, about 1,900 sq ft, in a polyurethane traffic membrane, aggregate wear coat, came in at an estimated $9,800 to $13,900 over an estimated 3 to 5 days. There are no more drips on the level below, and tenants kept parking on the rest of the deck.
Phasing a Garage That Cannot Close
A garage is coated section by section or bay by bay, so parking stays open through the whole job. We cone off one section of a North Tustin or Norco garage, post a dated notice ahead, and route traffic around the closure with the owner's attendant or security team. Each section typically closes an estimated 3 to 5 days from crack routing to the wear coat, and a fast-cure topcoat typically allows foot traffic in an estimated 4 to 8 hours. Medical and office garages in Claremont and Riverside usually close their sections over weekends, when stall demand is lowest.
How a Deck Job Runs
A parking deck job runs in five steps, the same on a two-level Eastvale garage as on a downtown Riverside podium.
- Deck survey inside our 45-mile radius, mapping every crack, joint, drain and spalled spot.
- Written bid per section, typically an estimated $5,500 to $14,000 for each 1,000 to 2,000 sq ft, with a phase map.
- Crack routing, joint detailing and patching, then the grind to a sound profile.
- Membrane base coat, wear coat with aggregate and the topcoat, typically an estimated 3 to 5 days per section.
- Restriping, stall numbers and the 2-year workmanship warranty against peeling, delamination and hot-tire pickup in writing.
Why Owners Choose Riverside Epoxy Flooring Group
Owners choose us because 12 years of phased commercial work has taught our crews to keep a garage earning while we coat it, and the crew that maps the cracks is the crew that seals them. Our owner walks each deck before a system is chosen, and coating makers' product warranties, typically 5 to 10 years on professionally installed systems, pass to you in writing.

Parking Deck Coating Questions
Why does a parking deck need a waterproofing membrane?
A membrane keeps water out of the slab and its reinforcing steel, as on Sharon's Riverside deck, where cracks were dripping onto the cars below.
Can the garage stay open while you work?
Yes, we close one section at a time, so the rest of the deck keeps parking, the way tenants in the Mission Inn district kept their stalls.
Do you fix cracks before coating?
Yes, every active crack on Diamond Bar and Yorba Linda decks is routed and sealed, and every joint detailed, before the membrane goes down.
How long is each section closed?
Most sections close an estimated 3 to 5 days, and a fast-cure topcoat typically allows foot traffic in an estimated 4 to 8 hours.
What does a parking deck coating cost?
Deck coatings typically run an estimated $5,500 to $14,000 per 1,000 to 2,000 sq ft section, and your written quote sets the final price.
Do you restripe after coating?
Yes, stalls, arrows and stall numbers in Claremont and Eastvale garages are restored once each section cures.
Which levels need the toughest system?
Open top decks and ramps take the most sun and tire scrub, so they get the UV-stable aliphatic topcoat and a heavier aggregate load on Norco and Woodcrest structures.
