Portland, OR Parking Deck Restoration & Waterproofing Services
Concrete Repair, Traffic Coatings & Expansion Joints for Portland Parking Garages
Parking Garage Restoration Contractors in Portland, OR
Portland’s parking garages serve the downtown core, the Pearl District, the Lloyd District, the South Waterfront, OHSU and the other hospitals, Portland State and the airport. Months of steady rain keep their decks wet, and water slowly works through worn coatings, cracks and failed joints until it reaches the reinforcing steel. Studded tires in winter wear down traffic surfaces, and the occasional ice storm brings de-icer. Once the steel starts to rust, it swells and breaks the concrete apart.
Presto Restoration has more than 25 years of experience restoring parking structures and above-grade concrete across the country. In Portland our crews remove deteriorated concrete, treat or replace corroded steel, rebuild joints and install traffic membranes that keep water out, scheduling coating work for dry weather and phasing it so the garage stays open.
OUR PARKING GARAGE RESTORATION SERVICES IN PORTLAND
Constant moisture is the main threat to a Portland garage. These are the repairs that keep it in check.
A traffic membrane keeps rain on top of the deck and out of the slab. After broken and cracked concrete is repaired, we install urethane or epoxy layers with grit for traction, durable enough for studded tires, during dry stretches so they bond properly.
Expansion joint seals in Portland garages wear out from traffic and stay wet for months, and a failed joint drips water and grime onto the level below. We remove the old joint, rebuild the edges and install compression or elastomeric seals.
Where a garage meets walls, columns, stair towers and neighboring buildings, the joints move in several directions. Flexible seals there keep water from running down the structure.
Water that sits on a deck for weeks finds its way into the concrete. We correct slopes and drains, seal the slab and joints together and protect stair and elevator cores.
Small cracks that stay wet all season give water a path to the steel. We rout and seal them with flexible material before they spread.

Portland Parking Garage Restoration FAQs
How often does a Portland parking garage need restoration?
Most garages need concrete and joint repairs every 8 to 12 years, with the traffic coating renewed on a regular cycle.
What are the warning signs of parking garage damage?
Rust stains, concrete that sounds hollow or breaks off, exposed rebar, worn coatings and joints that drip all winter are all signs of trouble.
Can the garage stay open during restoration?
Usually, yes. We close one zone at a time and work around hospital shifts, classes and events.
Can parking garage work be done during the rainy season?
Concrete repair can often continue under cover, but traffic coatings need dry surfaces, so we schedule them mostly from June through September.
How long does a parking garage project take in Portland?
A focused repair can take a few weeks, while restoring a large garage may take several months.
Does Presto handle permits for parking garage repairs?
Yes. We work with the City of Portland’s Permitting and Development office when permits are required, and with your structural engineer on load-bearing repairs.
