PARKING GARAGE
REPAIR & MAINTENANCE
IN HOWE, TX.
Howe's US-75 commercial strip grew from a 1880s grain-shipping railroad town into a gateway community serving the Sherman-Denison metro. The Union Pacific corridor still runs through town — and the persistent ground vibration it generates is a documented accelerant of sealant and joint failure in nearby parking structures. We repair and protect parking facilities built to last.
What Parking Garage Repair Includes
Comprehensive structural and waterproofing services for parking facilities — from spall repair to full deck membrane replacement.
Structural Concrete Repair
Delaminated and spalled concrete — especially on soffits and column faces — is the most visible sign of a parking structure in decline. We remove deteriorated material by hydrodemolition or hand tool, treat exposed rebar for corrosion, and restore profiles with structural repair mortars matched to the existing concrete's strength and porosity.
Howe's Grayson County clay soils and the ground vibration from the Union Pacific corridor accelerate microcracking in concrete slabs over time. Early intervention on spall repair prevents the rebar corrosion cycle from expanding and triggering costlier deck replacement.
Expansion Joint Replacement
Expansion joints are the planned weak points in a parking structure — designed to absorb movement without transferring stress to the slab. When they fail, water bypasses the deck membrane and reaches structural steel below. We remove failed materials, prepare joint substrates, and install compression seals or poured systems rated for the specific traffic load and thermal movement of each location.
North Texas temperature swings — from sub-freezing winter nights to 100°F+ summer days — demand joint systems with high elongation capacity. We specify accordingly.
Traffic-Bearing Waterproofing
Parking deck waterproofing must handle both vehicular wheel loads and continuous moisture exclusion. We install traffic-bearing membrane systems — typically polyurethane or methyl methacrylate (MMA) with broadcast aggregate wearing courses — that protect the structural slab while providing skid resistance for vehicles and pedestrians.
These systems are specified for the deck's expected traffic volume, whether light passenger vehicles or heavier delivery trucks, and are designed to allow future topcoat renewal without full membrane removal.
Post-Tension Cable Inspection & Repair
Post-tensioned parking decks concentrate enormous stress through cables embedded in the slab. Corrosion at anchorage pockets — typically caused by failed waterproofing at the deck perimeter — can compromise cable integrity and structural capacity. We inspect PT anchorage zones, remove corroded material, treat cables, and restore anchorage pockets with non-shrink grout.
PT cable repair requires specialized knowledge of the structure's stress patterns. We coordinate with engineering resources when cable conditions suggest structural evaluation is warranted.
Facilities We Serve in Howe
Why Howe Parking Structures Need Attention Now
Howe grew from exactly 2,600 residents in 2010 to 3,571 in 2020 — a 37% increase driven by southward spillover from the Sherman-Denison metro. That growth accelerated commercial development along the US-75 Business Route and US-75 frontage strip, producing a wave of structures now reaching 20–40 years old without systematic maintenance programs.
Two factors make Howe parking structures particularly vulnerable: the Grayson County heavy clay soils that shift with seasonal moisture and exert lateral pressure on foundations, and the Union Pacific rail line running through town whose vibration accelerates joint and sealant deterioration beyond what you'd expect from age alone. Deferred maintenance is common — the local median household income of $51,108 signals that repair cycles have historically been stretched.
As the southern gateway to the $35+ billion Texas Instruments and GlobiTech semiconductor corridor on US-75, Howe properties face rising competitive pressure from the Sherman metro. Facilities with deteriorating parking structures lose a first impression before a visitor reaches the front door.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures accumulate several categories of damage over time: spalled and delaminated concrete from rebar corrosion, failed expansion joints that allow water to penetrate to lower decks, deteriorated traffic-bearing waterproofing membranes, and post-tension cable corrosion in PT slab systems. In Howe and Grayson County, the Union Pacific rail corridor adds persistent ground vibration — an underappreciated factor that accelerates sealant and joint failure in nearby structures faster than you'd see in calmer environments.
How do you repair expansion joints in a parking structure?
Expansion joint repair begins with full removal of the failed filler material and any deteriorated concrete at the joint edges. We saw-cut, clean, and profile the substrate, then install a compression seal or poured sealant system rated for the structure's anticipated movement and traffic load. On parking decks exposed to vehicle traffic, we use heavy-duty compression seals or hot-applied rubberized systems capable of handling both wheel loads and the thermal movement that North Texas temperature swings — from freezing winters to 100°F+ summers — demand.
What is traffic-bearing waterproofing for parking garages?
Traffic-bearing waterproofing is a membrane system designed to handle both vehicle wheel loads and moisture exclusion simultaneously. Unlike standard roofing membranes, these systems include a wearing course — typically a broadcast aggregate or textured polyurethane — that protects the waterproofing layer from abrasion while maintaining traction. For Howe-area parking structures, we use systems that withstand Grayson County's clay soil–driven differential movement as well as the freeze-thaw cycling that opens small cracks each winter.
Can parking garage repairs be done without closing levels to traffic?
In most cases, yes — phased repair sequencing allows one level or section to be taken out of service at a time while the rest of the structure remains operational. We plan work areas, equipment staging, and cure windows to minimize disruption. Our 56' and 72' boom trucks eliminate the need for scaffolding on many exterior column and soffit repairs, further reducing the footprint of active work zones.
How do you prioritize repairs on an aging parking structure?
We start with a condition assessment — visual survey plus sounding (chain drag or hammer tap) to identify delaminated concrete, followed by review of any existing engineering reports. Repairs are prioritized by safety risk first (overhead spalls, PT cable exposure), then water infiltration severity (joint failures that allow water to reach lower levels or foundations), then surface deterioration. We provide a written repair priority matrix so owners can phase work across budget cycles rather than facing a single large mobilization cost.
