PARKING GARAGE
REPAIR & MAINTENANCE
IN DENTON, TX.
UNT and TWU together enroll approximately 57,000 students, putting daily heavy traffic loads on Denton's parking structures. Add North Texas Blackland Prairie clay movement and the $2.3 billion May 2024 hail event, and Denton's parking decks face a concentrated set of structural stressors that require specialist repair — not deferred maintenance.
What Parking Garage Repair Includes
Comprehensive structural repair and waterproofing for parking structures — from spalled decks to failed expansion joints.
Structural Concrete Repair
Spalled and delaminated concrete exposes rebar and post-tension cables to chloride attack, accelerating structural deterioration faster than almost any other failure mode. We remove unsound concrete to a sound substrate, treat exposed reinforcement, and restore the section using polymer-modified cementitious mortars matched to the existing concrete's strength and porosity.
In Denton's aging commercial and university parking structures, chloride penetration from decades of road salt and moisture infiltration often extends further than surface spalls suggest — our condition surveys include chain-drag testing to map delaminations before any repair work begins.
Expansion Joint Replacement
Parking structure expansion joints are the most common water intrusion point in multi-level decks. Failed compression seals, cracked nosing assemblies, and deteriorated sealant allow water and chlorides to migrate directly to the slab edge and level below, accelerating corrosion of embedded steel.
Denton's Blackland Prairie clay soil creates cyclical foundation movement that puts additional stress on joint assemblies beyond standard thermal expansion. We size and specify replacement seals to accommodate both thermal and settlement movement for the structure's actual conditions.
Traffic-Bearing Waterproofing
Parking deck waterproofing must withstand repeated vehicle loads while maintaining a continuous moisture barrier. We install reinforced traffic-bearing membrane systems with an integral wear course — systems rated for the specific traffic volume and vehicle types using the structure.
For Denton's high-traffic university and commercial parking structures, we specify systems with documented performance in comparable climates, verified by third-party testing. Proper membrane slope and drain detailing are addressed simultaneously to eliminate ponding water that accelerates membrane failure.
Post-Tension Cable Inspection & Repair
Post-tensioned parking structures require specialized inspection protocols to identify corroded or broken tendons before they cause catastrophic failures. Signs include anchor pocket corrosion, rust staining on soffits, and unexpected slab cracking patterns that don't match typical shrinkage cracks.
We inspect anchor pockets, grout tubes, and tendon profiles, and coordinate with structural engineers when cable repair or supplemental reinforcement is required. Repair scope is fully documented for owner records and future inspection reference.

Why Denton Parking Structures Need Specialist Repair
Denton's position at the I-35E/I-35W confluence gives it two large universities — UNT and TWU with a combined enrollment of roughly 57,000 — alongside a growing commercial base anchored by Peterbilt Motors' 700,000-square-foot manufacturing campus and Rayzor Ranch's 412-acre retail center. That volume of daily traffic concentrates chloride and impact stress on parking structures faster than lower-traffic commercial contexts.
The May 2024 North Texas hail event produced golf-ball to softball-sized hailstones, contributing to more than $2.3 billion in regional property damage. For parking structures, large hail impacts accelerate existing membrane failures and open hairline cracks in deck surfaces, creating new chloride pathways to embedded steel. Structures that weren't inspected after that event are at elevated risk for ongoing deterioration.
Denton's Blackland Prairie clay soil also creates cyclical foundation movement that stresses expansion joints and slab-on-grade sections differently than stable soil conditions. Our repair specifications account for this ongoing movement rather than treating it as a one-time repair scenario.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures in Denton typically need spalled concrete patching, expansion joint replacement, traffic-bearing waterproofing membrane repairs, and post-tension cable inspection. The University of North Texas and Texas Woman's University campuses together enroll approximately 57,000 students, generating heavy daily traffic loads across parking structures that range in age from newer decks to facilities built in the 1970s and 1980s. Heavy vehicle traffic accelerates chloride infiltration and freeze-thaw deterioration faster than almost any other commercial building type.
How do you repair expansion joints in a parking structure?
Expansion joint repair begins with full removal of the failed compression seal or nosing assembly, cleaning the joint substrate, and installing a new heavy-duty seal rated for vehicular traffic. On Denton's parking structures, where North Texas Blackland Prairie clay soil creates cyclical movement pressure, joints must accommodate both thermal expansion and differential foundation settlement. We match the seal type — compression seal, preformed foam, or poured elastomeric — to the joint width and movement range documented during inspection.
What is traffic-bearing waterproofing for parking garages?
Traffic-bearing waterproofing is a reinforced membrane system applied to parking deck surfaces that withstands vehicle loads while preventing water and chloride intrusion into the structural slab below. Unlike standard waterproofing coatings, these systems include a wear course tough enough for repeated tire contact. Denton's May 2024 hail event — which caused more than $2.3 billion in regional property damage — also drives water through any existing deck membrane failures, making timely repair critical before chlorides reach embedded post-tension cables or rebar.
Can parking garage repairs be done without closing levels to traffic?
Yes. We typically work level-by-level, keeping unaffected areas of the structure open while we complete repairs on each section. For UNT, TWU, and Denton's commercial facilities, maintaining access is essential — a full closure is rarely necessary and we coordinate work sequences to minimize disruption. Our 56' and 72' boom trucks also allow us to access elevated decks and soffits without blocking traffic lanes from below.
How do you prioritize repairs on an aging parking structure?
We start with a condition survey that maps delaminations (tested by chain-dragging), visible spalls, joint failures, drainage problems, and any signs of post-tension cable distress. Repairs are then prioritized by structural risk — active delaminations above cables, failed expansion joints admitting water, and membrane voids — before cosmetic or preventive work. Denton's commercial parking stock includes structures from the 1980s through early 2000s, a wide age range where condition varies dramatically by exposure and maintenance history.
