Traffic-Bearing Coatings, Expansion Joint Replacement & De-Icer Damage Repair for Above-Grade Parking Structures
Above-Grade Parking Deck Restoration Specialists in Boise, ID
Few parts of a commercial property work harder than its parking structure, and in Boise the hardest month of the year is January. Garages serving Downtown Core offices, the state government campus, and BoDo carry vehicle loads, tire abrasion, and dripped fluids all year. Then winter arrives and adds three things a mild climate never delivers: magnesium chloride and salt tracked in on every wheel that came off a treated street, a top deck that freezes and thaws again and again between December and March, and plow blades working directly across the traffic membrane. Chloride-laden meltwater is the specific problem. It soaks into any crack or pinhole in the coating, reaches embedded reinforcing steel, and drives the corrosion that lifts and spalls the slab from within.
Presto Restoration delivers parking deck restoration and waterproofing for above-grade parking structures across Boise, including elevated decks, freestanding garages, and rooftop parking levels alike. Pedestrian and vehicular traffic-bearing membranes get installed, horizontal and vertical expansion joints get replaced, and a higher-performing system is available on request. Drive lanes, parking bays, and stair towers also get full waterproofing and joint sealing. This practice does nothing but above-grade parking work, which is why the crew that arrives at your structure is already specialized in it.
OUR PARKING DECK RESTORATION SERVICES IN BOISE
From traffic coatings to expansion joint replacement, Presto offers a full lineup of parking deck restoration and waterproofing services built around what a Boise winter does to an above-grade parking structure.
Nothing on a parking structure works under less forgiving conditions than its waterproof membrane. It has to keep water out of the occupied levels below while standing up to constant tire scrubbing, vehicle loads, oil and chemical spills, and a substrate that expands and contracts every single day. In Boise it also has to survive de-icing chemicals and the steel edge of snow-removal equipment on exposed top decks. Presto installs high-performance traffic-bearing membranes for vehicular drive lanes and parking bays, along with pedestrian-rated systems for walkways, stair towers, and rooftop decks. These systems are applied as seamless liquid urethane and polymer coatings that bond tightly to the concrete, eliminating the seams where chloride-laden meltwater usually finds its path and creating a wear surface built for decades of winter service. Every installation follows manufacturer specification and is fully documented to protect your warranty coverage.
The horizontal expansion joints crossing a garage’s drive lanes let the structure flex with temperature swings and shifting loads, and in a climate that moves a deck thirty to forty degrees in a day they are working constantly. When their seals or hardware give out, meltwater carrying road salt pours straight through the deck to the parking levels beneath. Horizontal expansion joints are taken out and replaced in full, original hardware included. We can match the existing joint system in kind, or, when the owner prefers, upgrade to a newer, higher-performing product line. Having installed systems from virtually every major expansion joint manufacturer, our crews select the product best suited to your Boise structure’s movement range and traffic volume.
At the lines where a deck meets walls, columns, and adjoining building sections, vertical expansion joints take up movement that behaves nothing like drive-lane movement, and installing them well is its own technique. Vertical joint work covers the whole range here, from whole-system replacement and hardware swaps through resealing and spot repair. Getting these joints right closes off one of the most persistent water-entry points in Boise parking garages, and it keeps salted meltwater away from the reinforcing steel in the surrounding concrete.
A garage only stays dry when every route water can take has been closed. The traffic membrane is only part of it: control joints, construction joints, cold joints, and the dozens of places where drains, conduit, and structural members pass through the slab all count. Presto assembles a full deck waterproofing program from silicone, polyurethane, and polymer sealants, matching the chemistry to each joint profile and how exposed it is. On a Boise top deck the detailing around drains and scuppers matters more than the raw volume of water suggests, because a drain that backs up in a February thaw refreezes overnight and holds a block of ice directly against the membrane termination.
Some of the hardest-working sealant in a garage sits in its control joints, cold joints, and minor construction joints, and almost none of it gets looked at until it lets water through. Under wheel loads, ponded meltwater, and a daily freeze-thaw cycle, these sealants crack and debond early, and dry summer air stiffens whatever survives the winter. We cut out the spent material, bring each joint up to the manufacturer’s prep requirement with backer rod and primer where the spec calls for it, then install traffic-rated high-performance sealant. Intact joint seals are what keep water from slipping around the traffic membrane and straight into the slab, and that failure turns up again and again in garages waterproofed piecemeal over the years.
Our Parking Deck Restoration Process in Boise
Every Boise parking deck restoration project moves through a proven five-phase process built to pinpoint the real problem, specify systems that survive de-icing chemistry and freeze-thaw, and get the coatings down inside the season when they will cure.
Parking Structure Assessment
The walk covers the whole garage, traffic membranes through horizontal and vertical expansion joints, joint sealants, drains, and any live leak or stain showing on the levels underneath. On the exposed top deck we also look for plow scars and the chloride staining that marks where de-icer has been sitting.
Diagnostic Testing
Leaks in a parking structure rarely surface where the water actually gets in, and in Boise the water is often meltwater that entered weeks earlier. Targeted water testing and tracing pinpoint the joints, membranes, or penetrations actually causing the problem.
Scope & System Selection
We select traffic membranes, joint replacements, and sealants matched to your structure, its traffic patterns, and its de-icer exposure, with phasing planned to keep the garage as usable as possible and to finish before the first hard freeze.
Restoration Installation
Work moves through the deck in sections so some of it stays in service throughout. Materials go in per manufacturer spec, with tight control over substrate prep, moisture content, and cure times, which is what decides whether a coating survives its first Boise winter.
Closeout & Warranty
You receive full warranty paperwork, product data sheets, before-and-after photos, and maintenance guidance for every system installed, including a winter routine for keeping deck drains clear so meltwater never stands and freezes on the membrane.

Boise Parking Deck Restoration FAQs
How often should a commercial parking deck membrane be replaced in Boise?
Traffic-bearing membranes typically last 10-20 years depending on the system, traffic volume, and maintenance history. In Boise the exposed top deck is always the short straw: it takes de-icing chemicals, repeated freeze-thaw, ultraviolet at 2,700 feet, and occasional plow contact, so it usually needs replacement well before pedestrian membranes in covered areas do. A full parking structure inspection every 5 years catches deterioration before chlorides reach the reinforcing steel.
Which warning signs mean a parking deck needs restoration?
Watch for water dripping or staining on the levels beneath the deck, cracking or bubbling in the traffic membrane, gouges or worn strips where plow blades have run, expansion joint hardware that is loose or leaking, sealants pulling away from joint walls, efflorescence on concrete, and rust staining running down the slab. Rust staining in particular is a late signal rather than an early one, and warrants a professional inspection promptly.
Does the garage have to close during parking deck restoration?
In almost every case, yes. Phasing across deck sections keeps most of the garage usable, scheduling is set with property management, and tenants hear about any temporary lane or level closure before it happens. Membrane systems need uninterrupted cure time above a minimum substrate temperature, which is why Boise deck work is normally scheduled between spring and autumn rather than in midwinter.
Sealing an expansion joint versus replacing it: what changes?
Sealing replaces just the sealant material and leaves the existing hardware in place, which is the right call when the hardware still works and only the sealant has failed. Replacing means pulling out the old hardware or joint system entirely and installing new, which becomes necessary once the hardware is worn or corroded. We read the real condition of the joints in front of us and put forward the approach that fits, a newer joint system included where that is the better buy.
How long does a parking deck restoration project typically take in Boise?
Timing depends on the size of the structure and the scope of work, and on the calendar. A tightly scoped membrane replacement on a small deck lands in the two to four week range. A large multi-level garage taken all the way through traffic coatings, joint replacement, and full sealing occupies three to six months. Because coatings need warm, dry substrate to cure, we plan Boise projects to finish before the first hard freeze and lay out a detailed timeline during scoping.
Does Presto handle permits for parking deck work in Boise?
Yes. Our project management team files permit applications for parking deck restoration work directly with City of Boise Planning & Development Services, or with Ada County for structures outside city limits, and we coordinate with the General Contractor when one is managing other work at the property. Presto carries nationwide general liability and workers’ compensation insurance and complies with all applicable local and state requirements on every project.
