COMMERCIAL
PARKING GARAGE REPAIR
IN HOUSTON, TX.
Houston's off-street parking ordinance ties a building's required parking and loading to the whole period it is occupied or in use, so a garage here is repaired around a count it has to keep. The city's residential buffering amendments, which apply to commercial building-permit applications from February 25, 2023, add garage exterior-cover and lighting standards meant to keep headlights and garage lighting off neighboring residences. Both land on the same scope: how many spaces come out at once, and what the structure is allowed to show the street while they do.
What Parking Garage Repair Includes
A Houston garage repair is written against the city's current code package, adopted with the 2021 construction codes and effective January 1, 2024 across nine building codes, from the moment a slab or a joint is opened.
Structural Concrete Repair
Corrosion does the damage; the concrete only reports it. Griffin removes back to a sound bond line around each delaminated area, cleans and coats the exposed reinforcing, and rebuilds the section with a mortar matched to the slab for strength and porosity. When the deterioration goes through the slab, the item is written as full-depth replacement, shored and formed, and priced that way from the start.
Depth changes the paperwork as much as the price. Houston's adoption of the 2021 construction codes took effect January 1, 2024 and reached nine building codes, and a repair that reopens a structural slab gets read against that package rather than against the drawings the garage was built from. We mark the items likely to draw a permit review while the survey is still in the field.
Expansion Joint Replacement
A failed joint announces itself one level down, as a stain under the line rather than a defect on it. Replacement takes out the seal, the nosing, and the broken concrete edge carrying them, rebuilds that edge, and sets a system sized for the movement and the vehicle count at that location. Where the joint meets the deck coating, the two are terminated into each other rather than butted, because that seam is where the repeat leak usually starts.
Joint lines are the reason garage work here gets measured in spaces rather than square feet. One line can cross several bays and a ramp, and Houston's off-street parking ordinance expects sufficient parking and loading to be available while a building is occupied or in use. We set the closure sequence against the count the property has to hold, run the work in lengths that fit it, and weigh the joint system partly on how long it needs before cars come back.
Traffic-Bearing Waterproofing
Ramps and entrance levels take the hardest service in the structure: steering loads, braking, trapped heat, and whatever runs down off the street. Griffin coats them as their own lot, with a coarser broadcast for traction on grade and terminations detailed into the curb and the apron rather than stopped short of them. The transition at the entrance is treated as a joint between two water systems, the street's and the deck's.
Which levels sit inside the mapped boundary is worth settling before that lot is priced. City program guidance puts both the FEMA 100-year and 500-year floodplains inside Houston's Special Flood Hazard Areas, and the city's public flood-hazard map carries a dedicated 500-year layer for the 0.2-percent-annual-chance hazard. For a garage that lands on specific pieces: the apron, the entrance ramp, the lowest slab, and drains that are meant to discharge and can instead receive.
Post-Tension Cable Inspection & Repair
Pockets at the slab edge are where a post-tensioned deck keeps its strength, and they sit under the strip that loses its coating first and holds water longest. A pocket can give up a great deal before the surface above it shows a thing. Griffin opens the anchorage zones before any membrane goes down, takes out corroded material, treats the cables, and grouts the pockets closed with non-shrink grout. Some of what a pocket shows belongs to the engineer of record, and when it does, that evaluation happens before the scope is fixed.
That same perimeter usually carries the building's exterior cover. Houston's residential buffering amendments have applied to commercial building-permit applications since February 25, 2023 and set garage exterior-cover and lighting standards intended to keep headlights and garage lighting from reaching neighboring residences or streets. Where cover has to come off to reach a pocket, the schedule carries it back up as its own item, with the lighting checked against that standard before the elevation is handed over.

Houston Garages Are Repaired Around Capacity, Screening, and the Flood Map
The binding constraint on a Houston garage program is usually a number, and it is not the budget. The city's off-street parking ordinance requires new developments and redeveloped buildings or tracts to provide sufficient parking and loading facilities while they are occupied or in use, which makes available capacity an obligation attached to the property. Repair has to work inside it. We establish the count that stays open before sequencing anything, then size work areas to that count: how many bays at once, which ramp stays live, how long a coated area is out. Settle the number first and you get a schedule you can publish to tenants.
Whoever lives across the street is the other constraint. Houston's residential buffering amendments apply to commercial building-permit applications from February 25, 2023 and include garage exterior-cover and lighting standards meant to stop headlights and garage lighting from spilling onto neighboring residences. A structure permitted under that rule wears part of its compliance on the elevation, which turns panel and fixture work into items with a performance test behind them rather than a finish schedule. Our survey records the cover and the lighting alongside the concrete, because a panel swapped for a more open one can put the elevation back in front of a reviewer.
Underneath both sits a boundary the city publishes. City program guidance places both the FEMA 100-year and 500-year floodplains inside the Houston Special Flood Hazard Areas, and the city's flood-hazard map carries the 500-year layer as the 0.2-percent-annual-chance hazard, so the boundary governing an entrance ramp or a lowest level can be looked up. Houston plans its own assets that way: the 2026 IAH program pairs an 8,100-space employee parking lot and Terminal C pedestrian-bridge repairs with expanded detention at Reinhardt Bayou, Garners Bayou, and Turkey Creek. Parking, the walk in, and where the water goes are one program there. On one property they belong in one scope, so we record discharge points as carefully as deck area.
Houston builds parking at that scale alongside the pedestrian links and detention work that serve it, which is the pairing a single property's garage, walkways, and drains deserve as well.
Seven projects are funded together at one airport, which is what it looks like when parking, drainage, and access are planned as one asset rather than three budget lines.
From that year, commercial permit applications carry garage cover and lighting standards, so an exterior repair near residences answers to a performance target and not only a finish.

Which parts of a Houston garage does the flood map actually change?
The map changes the bottom of the structure and the ways in and out of it. City program guidance puts both the FEMA 100-year and 500-year floodplains inside the Houston Special Flood Hazard Areas, and the city publishes the 500-year layer on its own flood-hazard map as the 0.2-percent-annual-chance hazard, so a parcel can be screened against both before a scope is written. What that screening changes is specific: the entrance apron and ramp, the lowest slab and its drains, the wall the ramp runs against, and the assumption that a deck drain is always discharging rather than backing up. On a structure inside the mapped area we price the lowest level as its own condition, note where drainage and electrical equipment sits relative to the boundary, and keep those items out of the general deck lot. Above that level the work is an ordinary deck repair, and knowing which levels are which is half the value of the report.
Our last deck repair was designed under the previous code package. Does that matter now?
Houston's code package moved on January 1, 2024, when the city's adoption of the 2021 construction codes took effect across nine building codes, so a detail carried forward from an older project cites a document that has since been replaced. For in-kind work that is usually a paperwork question and nothing more. The exception is a repair that opens a structural assembly: full-depth deck replacement, anchorage work, guard and barrier elements, drainage that gets rerouted rather than restored. We identify those items in the survey, put them in front of the owner's engineer with the current package named, and keep the in-kind concrete and coating work moving while that review runs. What costs money is a schedule built on the assumption that last time's approach still applies unchanged.
Three bids on the same garage came back a factor of two apart. What separates them?
Usually what each one assumed rather than what each crew charges. The items that move a garage number are measured deteriorated area against an allowance, whether joint edge repair is carried with the joint or left as extra work, whether drains and slope corrections are in or out, shoring for full-depth areas, and the closure line itself. That last one weighs more in Houston than owners expect, because the city's off-street parking ordinance ties required parking and loading to the period a building is occupied or in use, and a bid assuming a whole level at a time is quoting a different job from one built around a capacity the property must hold. Ask each bidder for the deteriorated area they measured, the bays out of service per week, and the return-to-traffic time of the system they specified. Those three answers usually explain the spread without anyone reopening the scope.
The building's exterior work is already scheduled. Should the garage go into the same contract?
Often yes, and the reason is access rather than bookkeeping. A garage and the building it serves share elevations, lifts, staging ground, pedestrian routes, and the weeks in which any of that can be closed, so splitting them across two contracts tends to buy a second mobilization on the same frontage. Houston's own operators work the other way. In September 2026 the city approved $129.9 million in initial airport-system funding inside a seven-project, $229.9 million infrastructure program at George Bush Intercontinental Airport, carrying buildings, parking, canopies, and drainage as one program. There are fair reasons to keep them apart, usually different budgets or different approval calendars. We price the two as separate line items under a single schedule, so the owner can split them later without repricing either.
We can fund one phase this year. What has to be in it?
The first phase carries whatever can close a bay and whatever is still getting worse while you wait. Overhead spalls and loose soffit material come first, since they take spaces out of service on their own schedule. Joints and membrane breaches routing water onto beams, columns, or the level below come second, because every month they run adds concrete to next year's quantity. Cosmetic work comes last, and we will say when an item belongs there. The phase should also carry the cheap measures that protect what you are deferring: drain clearing, localized crack treatment, and sealing the joints above the areas being left. Deferral is a legitimate budget decision when the deferred items are named, dated, and photographed. It turns into a liability when nobody wrote down what was left.

Commercial Waterproofing
Below the lowest deck a garage stops being a concrete problem and becomes a water one: ramp walls, elevator and stair pits, and the slab where the structure meets the site. Griffin corrects those surfaces on the same Houston mobilization, which matters most on a parcel the city's flood layers already flag.
