PARKING GARAGE
REPAIR & MAINTENANCE
IN McKINNEY, TX.
McKinney ranked as the fourth fastest-growing large U.S. city from 2010 to 2019 — population grew from 54,369 in 2000 to over 210,000 today. That growth created two distinct needs: aging historic downtown parking structures past their original maintenance cycle, and early-2000s commercial garages now entering their first major waterproofing and expansion joint replacement window.
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 is both a safety hazard and a leading indicator of ongoing rebar corrosion. We remove deteriorated material, treat exposed rebar, and restore profiles with structural repair mortars matched to the existing concrete's compressive strength.
McKinney's rapid commercial build-out means thousands of parking structures faced their first major hail-damage assessment after the April 2024 event — surface damage from hail opens membrane breaches that allow moisture to reach structural concrete within the following 1–2 years if not addressed promptly.
Expansion Joint Replacement
Expansion joints allow structural movement without transferring crack stresses across the slab. When they fail, water infiltrates through the deck to structural steel below. We remove failed materials, prepare substrates, and install compression seals or poured systems rated for the specific traffic load and movement at each joint location.
Large McKinney parking structures serving employer campuses, retail anchors, and the TPC Craig Ranch corridor have high daily vehicle cycles — we specify heavy-duty systems designed for the actual load conditions rather than minimum specification.
Traffic-Bearing Waterproofing
Parking deck membranes carry both vehicle wheel loads and full responsibility for moisture exclusion from the structural slab below. We install polyurethane or methyl methacrylate (MMA) traffic-bearing systems with aggregate wearing courses that protect the membrane from abrasion while providing traction for vehicles and pedestrians in any weather.
For McKinney parking facilities that must maintain operations during repairs, MMA systems offer the advantage of rapid cure — returning a repaired deck section to traffic within hours rather than days.
Post-Tension Cable Inspection & Repair
Post-tensioned parking decks concentrate structural stress through cables anchored at the slab perimeter. Corrosion at PT anchorage pockets — typically initiated by failed deck waterproofing at perimeter edges — can compromise cable integrity and structural capacity. We inspect anchorage zones, remove corroded material, treat cables, and restore pockets with non-shrink grout before membrane restoration.
When PT cable conditions indicate a need for structural evaluation, we coordinate with engineering resources to ensure repairs address the structure's actual load requirements.

Why McKinney Parking Structures Need Attention Now
McKinney has two distinct parking structure populations. The Historic Downtown Square and county courthouse district contains structures that date to the mid-20th century — past two full service cycles of original waterproofing and joint systems. The Craig Ranch corridor, Stonebridge Ranch retail, and early McKinney National Airport business campuses represent early-2000s construction now reaching the 20-25 year mark where first-generation sealant and membrane systems reach end of designed service life simultaneously.
The Raytheon McKinney campus added a $100M, 178,000-sq-ft Advanced Integration Center in 2021 followed by a 438,000-sq-ft Phase II — large, complex exterior envelopes alongside high-use parking that requires the same precision attention as the buildings they serve. The Prysmian-Encore Wire campus ($500M expansion, 650,000-sq-ft new building) represents equivalent sustained need for industrial exterior and parking maintenance.
McKinney approved Hunt, Tennessee, and Lamar Streets infrastructure reconstruction for 2026–2027 — adjacent building and parking structure owners have a competitive window to upgrade before the street improvements are complete and tenant expectations rise to match the improved surroundings.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures accumulate several failure modes over time: spalled and delaminated concrete from rebar corrosion (particularly on soffits and column faces), failed expansion joints that allow water to bypass deck membranes and reach structural steel, deteriorated traffic-bearing waterproofing membranes, and post-tension cable corrosion at anchorage pockets. In McKinney, the April 8, 2024 hail event measured 2.75 inches and impacted approximately 2,514 properties — parking structures with compromised deck membranes from storm damage accelerate into structural deterioration faster than the visible surface damage suggests.
How do you repair expansion joints in a parking structure?
Expansion joint repair starts with full removal of deteriorated filler 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 load. McKinney's large parking structures — including those serving the Craig Ranch corridor, Stonebridge Ranch retail, and major employer campuses — require heavy-duty traffic-rated systems that can handle high daily vehicle cycles while accommodating North Texas thermal movement.
What is traffic-bearing waterproofing for parking garages?
Traffic-bearing waterproofing is a membrane system engineered for the dual demands of vehicle load and continuous moisture exclusion. These systems include a wearing course — broadcast aggregate or textured polyurethane topcoat — that protects the membrane from tire abrasion while maintaining traction. For McKinney's large commercial parking structures, we specify systems rated for the actual traffic volume, whether light passenger vehicles in retail lots or heavier service vehicles on loading dock aprons and grade-level areas.
Can parking garage repairs be done without closing levels to traffic?
In most cases, yes. We use phased sequencing to take one section or level out of service at a time while the rest of the structure remains open. For McKinney's high-use parking facilities — particularly those serving anchor retail tenants, employer campuses, and the Historic Downtown Square — we design work plans around peak traffic periods to keep disruption minimal. Our 56' and 72' boom trucks eliminate scaffolding on most exterior soffit and column repairs, keeping active work areas compact.
How do you prioritize repairs on an aging parking structure?
We begin with a condition assessment: visual survey plus chain-drag or hammer-tap sounding to locate delaminated concrete, combined with review of available engineering or inspection reports. Repairs are ranked by safety risk first (overhead spall hazards, PT cable exposure), then water infiltration severity (expansion joint failures and membrane breaches that allow water to reach structural steel), then surface deterioration. We deliver a written priority matrix that lets owners phase work across budget cycles. For McKinney's early-2000s commercial buildings now entering their first major sealant and membrane replacement cycle, this phased approach is especially cost-effective.
