PARKING GARAGE REPAIR
IN SAN ANTONIO, TX.
Downtown San Antonio expects a parking structure to finish its street side. The city's Downtown Design Guide discourages garages without an external architectural skin and asks the ground floor to hold an active use or screening, and it points the top deck toward stormwater treatment and photovoltaic panels. A structure built to that standard has repair scope in three places at once: the frame that holds the cars, the deck that sheds the water, and the elevation the sidewalk reads. All three are surveyed before a quantity is written.
What Parking Garage Repair Includes
San Antonio Public Works reviews how private development affects the drainage already in place, so a garage scope here follows the water off the deck as carefully as it follows the cracks across it.
Structural Concrete Repair
A garage deck hides most of its damage. Sounding across each level finds the delaminated areas that have not yet broken through, and those are marked, measured, and photographed before a saw cut is made. Removal runs back to sound material, exposed steel is cleaned and treated, and the patch is built up in a mortar matched to the slab around it. Full-depth loss changes the job, bringing shoring, traffic diversion, and a formed pour in place of a hand-applied repair.
The city's Downtown Design Guide pushes garages to carry an external architectural skin rather than show the street a bare frame, which puts a second system on the same concrete. Panel and louver anchors land in edge slabs and spandrel beams, the sealant behind them drains onto those same members, and the whole assembly sits over a sidewalk. Repair sequence at a street elevation is set by the pedestrian route as much as by the concrete.
Expansion Joint Replacement
An expansion joint is the one detail on a deck that has to move, seal, and carry a wheel load at the same time. Replacement takes the seal and the nosing out together with the concrete edges that support them, because a seal is only as straight as the edge it sits in. The new system is sized for the movement measured at that joint and the traffic it actually sees, then tied into the coating on both sides so the transition stays continuous.
The city's Storm Water Design Criteria Manual sets a 24-hour rainfall distribution as the basis for hydrograph runoff work and publishes design rainfall for storms as rare as the 500-year event. A deck's water load is a published number. Joints decide where that water goes. We record which ones are holding it, which are routing it inboard to a beam, and which have already stained the structure underneath, and that record sets the replacement order.
Traffic-Bearing Waterproofing
A traffic coating is a wear surface and a waterproofing layer in one product, and it usually gives out at the wear surface first. We choose between polyurethane and methyl methacrylate on the closure window an operator can actually give up, treat moving and static cracks differently before anything is applied, and build the film to the thickness the survey calls for. Ramps, turn lanes, and the concrete around drains take the heavier build, because that is where tires work hardest.
The Downtown Design Guide wants more from a top deck than parking: stormwater treatment, renewable materials picked for proven longevity, and photovoltaic panels where they can be fitted. A top level carrying any of that is no longer a plain slab. Pads, curbs, and penetrations interrupt the membrane, so we detail the coating around what is already mounted and leave terminations a later installer can tie into without opening the field of the deck.
Post-Tension Cable Inspection & Repair
Post-tensioned decks concentrate their stress at anchorage pockets around the slab perimeter, which is also where water collects and where coatings and joints give out first. Corrosion in a pocket takes capacity long before the surface shows anything. We inspect the anchorage zones, remove corroded material, treat the cables, and restore the pockets with non-shrink grout ahead of deck membrane work. Where conditions indicate a structural evaluation, we coordinate with engineering resources before scope is fixed.
San Antonio's adopted code set has included the 2024 International Building Code, the existing-building code, and the property maintenance code, with local requirements, since May 1, 2025. A post-tensioned garage is one of the few structures where a maintenance obligation and a structural question meet in the same patch of concrete, so what we find at a pocket is written up for the engineer of record and for the owner's file whether or not it changes this year's scope.

San Antonio Garages Answer to Structure, Street Wall, and River
San Antonio's Downtown Design Guide discourages parking garages without an external architectural skin, and it asks the ground floor to hold an active use or screening that keeps bumpers and headlights out of view. Downtown, that guidance is already built. The garages here wear panels, louvers, or precast, and many of them lease their street frontage to a tenant. A contract written for the deck alone leaves an owner holding the rest: the anchors, the sealant joints behind the panels, the soffit over the sidewalk, and a second contractor to bring in for them. We scope the elevation and the structure together, off the same access equipment, so the block is opened once.
The largest parking asset the city has on paper is the planned airport Ground Transportation Center structure, estimated to hold 2,500 vehicles at 450 to 500 spaces per level, with a top floor designed to support possible future electric vertical takeoff and landing operations. Aircraft aside, that is a statement about expectations. New capacity here is being detailed for heavy daily turnover and for loads nobody has committed to yet, and a structure built on that premise holds up only if its joints, coatings, drains, and anchorage zones stay reachable. An existing garage earns the same standing by having its condition recorded level by level, so the next lender or engineer has measurements to work from.
A garage near the river does not discharge into a neutral place. A city planning document puts the San Antonio River Improvements Project at $384.5 million over 13 miles, combining flood control with habitat renewal, recreation, and public amenities. Water leaving a deck joins a corridor someone engineered on purpose, and the property's own collection points are the last part of it anyone maintains. Our survey records where each line discharges, what condition those collection points are in, and which below-grade walls are taking water from the site rather than from the structure above. That record is what an owner hands a civil engineer when the leak turns out to be the site's problem rather than the deck's.
A single asset at that capacity concentrates an operator's parking into one maintenance history and one closure plan.
New design here is organized by level, and so is everything that follows it: the survey, the coating lot, the closure, and the invoice.
Authorized across 23 drainage and flood-control projects, which is the scale of public system a garage's discharge line eventually meets.

Parking Garage Repair FAQ — San Antonio, TX
Our garage has a screen over the parking levels. Is that part of a concrete repair scope?
It should be. San Antonio's Downtown Design Guide discourages garages without an external architectural skin and asks the ground floor to carry an active use or screening, so a downtown structure here usually has a second system hung off its frame. Panels, louvers, and their anchors share the edge slabs and spandrels the concrete work is aimed at, and the sealant behind them is often the joint routing water into the member below. We survey the screen with the structure, price panel removal, storage, and reinstallation as their own line items, and note which panels have to go back in a set order for the elevation to read the way it did. Leaving the skin out of a garage scope generally buys a second mobilization on the same frontage.
Water stands on the top deck for a day after a storm. What does that tell you?
Usually that the deck is no longer draining the way it was designed to, and sometimes that it never did. San Antonio's storm water design criteria run on a 24-hour rainfall distribution, so drainage here is evaluated against a whole day of water rather than a single downpour, and a pond still sitting the next morning says the path is blocked or gone rather than overwhelmed. Standing water points at one of three conditions: slope the slab has lost, a drain that has silted or settled, or a curb or joint holding water against the coating. We clear and inspect the drains first because that is the cheapest answer, shoot the low points against the original deck profile, then choose between a localized re-slope, a drain correction, and a coating lot. Ponding also ages a traffic coating faster than tires do, which is why that finding carries a date in the report.
We want to put photovoltaic panels or stormwater treatment on the top deck. What has to happen first?
The deck has to be sound, drained, and sealed before anything is mounted on it. The Downtown Design Guide encourages that kind of addition and names the top deck as the place for it, which is a fair reading of where a garage has spare roof. Sequence is the whole issue, because every pad, curb, and penetration added afterward cuts a membrane the coating crew has just made continuous. Where the schedule allows, concrete repair and the traffic coating finish ahead of the installation. Where it does not, we detail terminations and flashings the mounting contractor can tie into and mark them on the close-out drawings. The condition record also gives a structural engineer the starting point they ask for first when new load goes onto an existing slab.
Does a garage repair in San Antonio bring the city into the drainage question?
Only when the repair changes how the site sheds water. San Antonio Public Works reviews commercial stormwater development plans so private work does not make existing drainage systems worse, and a scope that puts back what was already there rarely raises that question. A re-slope, a relocated discharge point, or a new connection can. We separate the restorative half of a garage scope from the half that alters drainage behavior, put the second in front of the owner's civil engineer early, and keep the first moving while it is answered. Where a garage drains into a site system that also serves the building, both get documented, since the two usually sit on different maintenance contracts.
Our garage is post-tensioned. What does that change about the repair?
It changes where the survey looks first and what we will not cut without a drawing. On a post-tensioned deck the stress sits in cables anchored at pockets around the slab perimeter, which is also the strip that collects water, loses its coating first, and shows the least on the surface. Corrosion there takes capacity long before it takes concrete. We get into the anchorage zones before the deck work starts, clear the corrosion, treat what is there, and grout the pockets closed, and no saw cut or anchor goes into the slab until the tendon layout is documented. When what we find in a pocket calls for a structural evaluation, that goes to the engineer of record before the scope is fixed, and the finding sits in the owner's file either way.

Commercial Waterproofing
A garage rarely leaks alone. The below-grade wall behind it, a planter deck over occupied space, or a stair tower that has never been dry belong to the same water path, and those corrections happen while the access equipment is already standing.
