PARKING GARAGE
REPAIR & MAINTENANCE
IN PLANO, TX.
The Legacy Business District's first buildings date to Frito-Lay's 556,000-sq-ft campus in 1985 — 40 years of North Texas weather, DFW hail events, and daily vehicle cycles on parking decks where original waterproofing and expansion joint systems have long outlived their designed service life. AT&T's $1.35B global HQ arriving at 5400 Legacy Drive raises the standard for every structure in the corridor.
What Parking Garage Repair Includes
Comprehensive structural and waterproofing services for parking facilities — from spall repair to full deck membrane replacement.
Structural Concrete Repair
Spalled and delaminated concrete on soffits, column faces, and deck edges creates overhead hazards and exposes structural steel to accelerating corrosion. We remove deteriorated material, treat rebar, and restore profiles with structural repair mortars engineered for the compressive strength and porosity of the existing concrete.
Plano's Legacy District parking structures built in the late 1980s through mid-1990s are at the age where rebar corrosion cycles — initiated by membrane and joint failures decades ago — have reached spalling stage. The J.C. Penney HQ complex (now The Park at Legacy, built early 1990s) and comparable vintage campuses represent exactly this profile.
Expansion Joint Replacement
Expansion joints allow the slab movement that thermal cycling and structural loads demand. When they fail, water routes past the deck surface to structural steel below — initiating corrosion that compounds invisibly until concrete spalls or steel section loss becomes visible. We remove all deteriorated material, prepare substrates, and install compression seal or poured systems sized for the actual movement and vehicle traffic at each joint.
For Plano corporate campus parking — structures serving 4,000+ daily employees on Toyota's campus alone — we specify systems rated for high daily vehicle cycles with the thermal movement tolerance required by North Texas temperature extremes.
Traffic-Bearing Waterproofing
Parking deck membranes carry simultaneous demands: vehicle wheel loads and complete moisture exclusion from the structural slab below. We install polyurethane or methyl methacrylate (MMA) traffic-bearing systems with aggregate wearing courses that resist tire abrasion while maintaining year-round traction.
For Plano's high-use corporate and retail parking, MMA systems offer rapid cure — returning a repaired section to traffic within hours — making them the preferred choice for facilities that cannot tolerate extended closures. Full-deck membrane replacement on Legacy District garages is often combined with joint replacement to eliminate redundant mobilization costs.
Post-Tension Cable Inspection & Repair
Post-tensioned decks concentrate structural stress through cables anchored at the slab perimeter — exactly where waterproofing failures begin and where moisture exposure is highest. Corrosion at PT anchorage pockets compromises cable integrity and structural capacity well before it presents visible surface damage. We inspect zones, remove corroded material, treat cables, and restore pockets with non-shrink grout before deck membrane restoration.
When PT cable conditions indicate the need for structural evaluation, we coordinate with engineering resources to ensure repair scope addresses the structure's actual load requirements and any implications for the existing cable stress profile.

Why Plano Parking Structures Need Attention Now
The Legacy Business District was conceived by Ross Perot in the early 1980s and now spans 2,665 acres. Frito-Lay's 556,000-sq-ft campus — one of the first major occupants, joining in 1985 — has 40 years of exterior exposure requiring multiple rounds of caulking, waterproofing, and facade repair. The broader district contains dozens of campuses where sealant and waterproofing systems originally installed in the late 1980s and early 1990s have long exceeded their designed service life simultaneously.
AT&T's January 2026 announcement of a $1.35B, 54-acre global HQ at 5400 Legacy Drive — with Plano City Council approving $20M in incentives on February 23, 2026 — changes the competitive standard for every surrounding parking structure. The former J.C. Penney HQ (1.8M sq ft, 50 acres, built early 1990s) is undergoing $1B redevelopment into The Park at Legacy — comparable vintage campuses are under the same pressure to restore Class A standards.
The DFW hail corridor runs directly through Plano. The May 2024 event caused $2.3B+ in regional damage; June 2023 storms caused $7-10B in insured losses. The high density of glass curtain-wall towers makes post-storm envelope inspection — including parking structure decks — a recurring annual expense. Structures with already-aging membranes suffer compounding damage from each event.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures develop several compounding failure modes: spalled and delaminated concrete from rebar corrosion, failed expansion joints that route water past deck membranes to structural steel below, deteriorated traffic-bearing waterproofing membranes, and post-tension cable corrosion at anchorage pockets. In Plano's Legacy Business District, original sealant and waterproofing systems installed in the late 1980s and early 1990s have long exceeded their 20-25 year designed service life — and the May 2024 hail event that caused $2.3B in regional damage, plus the June 2023 storms that produced $7-10B in insured losses, have opened membrane breaches in structures across the city.
How do you repair expansion joints in a parking structure?
Expansion joint repair starts with full removal of deteriorated filler material and any degraded concrete at joint edges, then saw-cutting, cleaning, and substrate profiling before installing a new compression seal or poured sealant system. System selection is based on the joint's movement profile and traffic volume. For Plano's large corporate campus parking structures — where Toyota's North American HQ alone spans seven buildings across a 100-acre, 2.1M-gross-sq-ft campus — we specify systems rated for high daily vehicle cycles and the full thermal movement range of North Texas weather.
What is traffic-bearing waterproofing for parking garages?
Traffic-bearing waterproofing is a membrane system engineered for the dual demands of vehicle wheel load and continuous moisture exclusion. These systems include a wearing course — broadcast aggregate or textured polyurethane topcoat — that protects the membrane layer from tire abrasion while providing traction. For Plano's corporate campus and Class A office parking structures, we often specify methyl methacrylate (MMA) systems, which cure in hours rather than days and minimize the disruption to high-use facilities during active repair windows.
Can parking garage repairs be done without closing levels to traffic?
In most cases, yes. Phased repair sequencing takes one level or section out of service at a time while the rest of the structure stays operational. For Plano's high-occupancy corporate parking facilities — including campuses serving 4,000+ daily employees — we design work plans around shift patterns and peak use hours to minimize disruption. Fast-cure MMA membrane systems allow repaired sections to return to traffic within hours. Our 56' and 72' boom trucks keep exterior column and soffit repair footprints compact without scaffolding.
How do you prioritize repairs on an aging parking structure?
We begin with a condition assessment: visual survey plus sounding to locate delaminated concrete, combined with available engineering or inspection reports. Safety-critical items come first — overhead spall hazards and exposed PT cable anchorages. Water infiltration sources come second: failed expansion joints and membrane breaches that allow water to reach structural steel. Surface deterioration is addressed last. We provide a written priority matrix so owners can phase work across budget cycles. For Plano's Legacy District buildings where sealant and waterproofing systems installed in the late 1980s are being replaced in their entirety, a phased approach distributes the investment over two to three years without deferring safety-critical work.
