PARKING GARAGE
REPAIR & MAINTENANCE
Parking structures are among the most demanding environments for concrete and waterproofing systems — constant vehicle traffic, thermal cycling across large deck spans, and chloride exposure from road salts and tire pickup all accelerate deterioration. Griffin Restoration Inc. provides self-performing parking garage repair and maintenance across North Texas and Southern Oklahoma, with 26+ years of experience in structural joint repair, traffic coating, concrete restoration, and deck waterproofing on municipal, institutional, and commercial structures.
What Parking Garage Repair & Maintenance Includes
Full-service parking structure maintenance — from traffic-bearing joint systems to structural concrete restoration and deck waterproofing.
Structural Joint Repair
Expansion joints in parking structures carry a heavier burden than those in any other building type. They must accommodate thermal movement across large concrete deck spans, deflection under moving vehicle loads, and seismic racking — often simultaneously. Traffic-bearing expansion joint systems consist of a flexible nosing material, a waterproofing element, and a compression seal or header system, all of which must remain intact for the joint to perform. When any component fails, water penetrates to the reinforcing steel below, initiating the corrosion cycle that causes concrete delamination and spalling.
Griffin Restoration removes and replaces failed parking structure expansion joints using products rated for vehicular traffic and the specific movement range of each joint location. We match joint system types — compression seals, foam-backed systems, or armored nosings with membrane waterproofing — to the structural engineer's joint design and the deck's observed movement. On post-tensioned concrete decks, which are common in newer North Texas parking structures, we coordinate closely around tendon locations and avoid any saw-cutting or anchoring without proper documentation of the tendon layout.
Traffic Coating Application
Traffic coatings are the primary waterproofing and wear surface on exposed parking decks and the upper levels of enclosed structures. A properly installed traffic coating system — typically a multi-component polyurethane system applied over a prepared concrete substrate — protects reinforcing steel from chloride-induced corrosion, resists petroleum products and tire abrasion, and provides the slip resistance required by code at pedestrian circulation areas. Coating systems that are improperly applied, applied over a contaminated substrate, or specified at insufficient thickness fail by delamination, often within two to five years.
Our traffic coating work begins with thorough surface preparation: shot blasting or scarifying to remove contamination and open the concrete surface profile, followed by crack repair and joint detailing before any coating is applied. We work in sections that maintain traffic flow on the remaining deck bays, coordinating with facility management on sequencing that minimizes operational disruption. North Texas summer heat creates application windows that must be carefully managed — fresh concrete and high surface temperatures both compromise polyurethane coat adhesion and cure, and our crews are experienced in working within these constraints.
Concrete Restoration
Delaminated and spalled concrete in parking structures is both a structural and a liability concern. Concrete that has lost bond to the underlying deck or column substrate can fall, and even a small falling piece represents a serious injury risk in a public parking environment. Restoration begins with systematic delamination sounding — hammer-tapping the entire deck and column surface to identify hollow areas that will fail under traffic loading — followed by saw-cutting the perimeter of each repair area, removing all loose and contaminated concrete, cleaning the reinforcing steel to bare metal, treating corroded steel with a rust-inhibiting treatment, and placing polymer-modified concrete or cementitious repair mortar to grade.
For parking structures where corrosion has progressed significantly — common in structures that were left without waterproofing protection for extended periods or that received inadequate initial waterproofing — a comprehensive condition assessment using carbonation depth testing and chloride profiling allows us to forecast the repair cycle and provide owners with a realistic 10- to 20-year maintenance budget rather than a reactive cycle of emergency repairs. Griffin Restoration self-performs concrete restoration without subcontracting, which maintains quality control at the crew level and eliminates the coordination delays that multi-contractor projects introduce.
Deck Waterproofing
Below-grade and enclosed parking levels that are not exposed to direct traffic typically require a membrane waterproofing system at the slab level rather than a traffic coating. Waterproof membranes at these locations protect the occupied or mechanical spaces below from drainage water and groundwater intrusion, and they must be integrated with the drainage system — typically a drainage mat or composite drainage board over the membrane — to manage water that enters through surface cracks before it can accumulate under hydrostatic pressure.
We specify and install membrane systems appropriate to the specific exposure condition: self-adhering modified bitumen membranes for protected applications, fluid-applied urethane membranes where irregular geometry or penetrations make sheet goods impractical, and bentonite systems for below-grade walls with soil-contact conditions. Regardless of system type, detailing at drains, curbs, columns, and wall-to-slab transitions requires field skill and deliberate attention — these details represent a small percentage of total membrane area but account for the majority of post-installation failures. Griffin Restoration's 26+ years of waterproofing experience in North Texas and Southern Oklahoma means our crews have encountered and resolved these conditions repeatedly.
