PARKING GARAGE
REPAIR & MAINTENANCE
IN ALLEN, TX.
Allen's One Bethany at Watters Creek campus — 475,000 sq ft of Class A office space — set the standard for corporate presentation in Collin County. The parking structures serving that corridor are now 6-20 years old, and Blackland Prairie clay cycling plus annual hail events are working against every original membrane and expansion joint.
What Parking Garage Repair Includes
Comprehensive structural repair and waterproofing for commercial parking structures — from spall repair to post-tension cable restoration.
Structural Concrete Repair
Spall repair, crack injection, and rebar treatment for columns, beams, elevated decks, and ramp structures. We restore load-bearing capacity to deteriorated structural members.
For Allen parking structures where Collin County's expansive clay soils place cumulative stress on columns and foundations, we specify repair mortars matched to the original concrete's compressive strength — not generic patching compounds — to ensure structural continuity.
Expansion Joint Replacement
Remove failed joint systems and install new traffic-rated expansion joints sized for the structure's thermal movement. Includes nosing repair and header concrete restoration.
Allen's temperature swings from North Texas summers to winter freezes require joints that accommodate significant thermal movement. Failed nosing concrete and header spalling are repaired as part of the same mobilization.
Traffic-Bearing Waterproofing
Vehicular-rated membrane systems for parking decks that seal against water infiltration while withstanding tire traffic, de-icing chemicals, and UV exposure.
The May 2023 Collin County hailstorm caused an estimated $300-$400 million in damage — parking deck membranes compromised by hail impact are an underdiagnosed infiltration source. We inspect membranes for impact fractures not visible to the naked eye.
Post-Tension Cable Inspection & Repair
Locate, test, and repair post-tension tendons showing signs of corrosion or stress loss. Includes pocket repair, stressing, and grouting of compromised anchorages.
Post-tensioned construction is common in Allen's 2000s-era parking structures. Corrosion at anchor pockets — often invisible until concrete spalls — compromises structural capacity. Early detection and pocket repair prevents costly tendon replacement.

Why Allen Parking Structures Need Attention Now
Allen's commercial building stock has a median year built of 2003, meaning the first wave of corporate office parks, retail centers, and their associated parking structures are now 20-25 years old — the window when original traffic-bearing membranes, expansion joint systems, and sealants reach end of service life simultaneously.
One Bethany North — a nine-story, 225,000-sq-ft tower at an estimated project cost over $100 million — is under development in the Watters Creek corridor. Buildings and parking structures serving that corridor face competitive pressure: tenants choosing between existing and new facilities notice deferred maintenance immediately.
Collin County sits within the expansive Blackland Prairie clay zone covering over 60% of its land area. The shrink-swell cycle stresses parking structure columns, ramp connections, and slab-on-grade areas year over year — a factor that accelerates concrete deterioration well beyond what climate alone would cause.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures in Allen experience concrete spalling at columns and elevated decks, failed expansion joints that allow water onto lower levels, deteriorated traffic-bearing membranes, and post-tension tendon corrosion. Allen's Collin County Blackland Prairie clay soils — which can swell up to 12% in volume — place cumulative stress on parking structure foundations and columns. Add the 2-3 annual hail events tracked up US-75 from Dallas and you have a recipe for accelerated deck and facade deterioration. A systematic condition assessment identifies which repairs are urgent and which can be scheduled.
How do you repair expansion joints in a parking structure?
We remove the failed joint assembly completely — including deteriorated nosing concrete and header material — then prepare the substrate by sawcutting clean edges and profiling the concrete. New traffic-rated joint systems are sized for the structure's actual thermal movement range, not the original spec, which may have been undersized. For Allen parking structures serving facilities like the One Bethany campus and Watters Creek retail corridor, we use compression-seal or preformed silicone systems rated for vehicular loads and de-icing chemicals. Nosing repair and header concrete restoration complete the work so the deck surface is flush and the joint is fully functional.
What is traffic-bearing waterproofing for parking garages?
Traffic-bearing waterproofing is a vehicular-rated membrane system applied to parking decks that seals against water infiltration while withstanding tire traffic, de-icing salt, and UV exposure. Unlike standard roof membranes, these systems are formulated to flex under load without cracking and resist the abrasion of tire contact. For Allen parking structures — where Collin County's expansive clay cycling causes subtle structural movement — flexible urethane or epoxy-urethane systems that bridge developing cracks are typically recommended over rigid coatings. We apply these in a two-component system with base coat, reinforcing fabric at seams and drains, and a UV-stable wear coat.
Can parking garage repairs be done without closing levels to traffic?
Yes — phased repair is standard practice for occupied parking structures in Allen, where facilities like One Bethany's 475,000-sq-ft Class A campus require continuous parking access during business hours. We coordinate work on individual bays or levels during off-peak periods, maintain clear traffic routing through the active repair zone, and schedule high-disruption work (concrete saw cutting, joint removal) during evenings or weekends when volume is lowest. Expansion joint replacement and membrane application require temporary closure of the affected drive lane, but the structure remains operational on other levels. A pre-construction phasing plan documents all access restrictions.
How do you prioritize repairs on an aging parking structure?
We assess structural urgency first: active spalling at load-bearing columns or post-tension tendon corrosion takes priority over cosmetic surface deterioration. Next are water infiltration pathways — failed expansion joints and membrane breaches that allow chloride-laden water to reach reinforcing steel. Allen parking structures from the 2000s and early 2010s — the city's median year built is 2003 — are now entering the 15-25 year window where original membranes and joint systems reach end of service life simultaneously. We use a written condition report with a priority matrix, so facility managers can plan capital expenditures and phase work across multiple budget years.
