PARKING GARAGE
REPAIR & MAINTENANCE
IN BONHAM, TX.
Bonham's commercial building stock has a median year built of 1975 — most parking structures serving the VA Medical Center campus, historic Courthouse Square, and the Highway 82 industrial corridor are 50+ years old. Blackland Prairie clay soils measuring up to 14,000 lbs/sq-ft of expansion pressure accelerate joint and deck deterioration beyond what age alone would cause.
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 Bonham parking structures serving the VA Medical Center campus and the federal facilities that must meet strict facility-condition index standards, we use polymer-modified repair mortars and corrosion-inhibiting rebar treatments specified to federal and ICRI standards.
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.
Fannin County clay soils exert measured pressures up to 14,000 lbs/sq-ft — among the highest in North Texas. Parking structure joints in Bonham must be sized for soil-driven differential movement in addition to standard thermal cycling. Original 1970s joint assemblies are wholly inadequate for this load environment.
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.
A June 2025 severe thunderstorm struck Bonham with winds up to 90 mph and quarter-size hail. A 2012 supercell in Fannin County caused an estimated $905 million in North Texas damage. Parking deck membranes exposed to repeated severe hail require inspection for impact-related fractures that bypass visual surface inspection.
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 structures built in the 1970s-1980s are now 40-50 years old — the window where tendon corrosion at anchor pockets becomes structurally significant. For Bonham's federally managed facilities, post-tension condition is a key facility-condition index item requiring documented inspection and remediation.

Why Bonham Parking Structures Need Attention Now
The majority of Bonham's commercial building stock is at or past the 50-year mark. The Sam Rayburn Memorial VA Medical Center — Bonham's largest employer and one of its most complex facilities — is a multi-building federal campus where facility-condition index scores directly affect capital improvement funding allocations.
Vector Systems Inc.'s 2026 relocation from McKinney to a new 56,000-sq-ft facility off Highway 82 — projecting 230 jobs at full build-out — signals that Bonham is attracting professional manufacturing operators who will bring DFW-caliber facility standards. Existing commercial properties face tenant-retention pressure from a newer competing facility within the same market.
Griffin Restoration is headquartered in Whitesboro, approximately 35 miles west of Bonham. We operate regularly in Fannin County and understand the specific soil, weather, and structural challenges of the area — from the Blackland Prairie clay pressures to the severe storm exposure documented in Bonham's recent weather history.

Parking Garage Repair FAQ
What types of repairs do parking garages typically need?
Parking structures in Bonham 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. With a median commercial year built of 1975, most of Bonham's parking infrastructure is now 50+ years old — well past the threshold where original waterproofing systems, joint assemblies, and surface treatments have failed. The Sam Rayburn Memorial VA Medical Center campus, Bonham's largest institutional employer, represents a multi-decade facility with strict federal facility-condition index requirements. A systematic condition assessment identifies which repairs are urgent and which can be phased over multiple budget cycles.
How do you repair expansion joints in a parking structure?
We remove the failed joint assembly completely — deteriorated nosing concrete, header material, and the old joint filler — then sawcut clean edges and profile the concrete substrate. New traffic-rated joint systems are sized for the structure's actual thermal movement range. For Bonham parking structures where Blackland Prairie clay soils on the eastern edge of the clay belt exert pressures up to 14,000 lbs/sq-ft — among the highest measured in North Texas — we specify flexible joint systems that accommodate the differential movement from both thermal cycling and soil-driven foundation movement. Nosing repair and header concrete restoration complete the work in the same mobilization.
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 flex under load without cracking and resist abrasion from tire contact. For Bonham's older parking structures — particularly those serving the VA Medical Center campus and historic Courthouse Square — retroactive installation of a traffic-bearing urethane membrane stops ongoing rebar corrosion and extends structural life at a fraction of reconstruction cost. We apply these in a multi-layer system with reinforcing fabric at seams, drains, and transitions.
Can parking garage repairs be done without closing levels to traffic?
Yes — phased repair is standard practice for occupied facilities. For Bonham structures including the Sam Rayburn Memorial VA Medical Center campus (where continuous patient and staff access is non-negotiable) and commercial parking supporting the downtown historic district, we coordinate work on individual bays or levels during off-peak periods. High-disruption operations like concrete saw cutting and joint removal are scheduled during evenings or low-volume windows. Expansion joint replacement and membrane application require temporary closure of the affected drive lane, but the structure remains accessible on adjacent areas. A pre-construction phasing plan is provided to facility management before work begins.
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. Bonham's commercial median year built of 1975 means most parking structures are at or past the 50-year mark, the threshold where concrete carbonation commonly reaches the depth of reinforcing steel in original construction. We provide a written condition report with a priority matrix. For Bonham's federally managed facilities like the VA campus, this report format aligns with standard facility-condition index documentation requirements.
