Why GSS
Parking garages take road salt, water and freeze-thaw every winter. Over time the concrete cracks, the rebar inside rusts, and pieces of columns, slabs and ramps start to let go. GSS is a concrete repair contractor in Toronto. We use the same crews, forms and rebar supply we use on new foundations, and we work to your engineer’s repair spec.
01
Our crews do the work themselves. You deal with the same company from the site visit to the last repair.
02
Forming, reinforcing and pouring structural concrete is our main work. Repair uses the same skills on an existing building.
03
Repair areas, rebar treatment and materials follow your engineer’s drawings. We ask questions before we start, not after.
04
WSIB cleared with $5 million in liability insurance. Certificates on request, before we start.
In short
A repair contractor removes damaged concrete, treats or replaces the rusted rebar, and rebuilds columns, slabs, ramps and walls to the engineer’s repair design. GSS does structural concrete repair for condo corporations, property managers and building owners across Toronto and the GTA, in phases that keep the building working.
We remove loose and delaminated concrete, clean and treat the exposed rebar, add new steel where the engineer calls for it, then form and pour or rebuild the column to its original shape. Temporary shoring goes in first where the design requires it.
We do top-side and underside repairs on suspended garage slabs and ramps, partial-depth or full-depth as the spec requires. We saw-cut the edges, remove the concrete back to sound material, treat the rebar and place new concrete, finished to match the drive surface.
We repair spalled, cracked and leaking garage walls. Damaged concrete comes out back to sound concrete, the rebar is treated, and the wall face is rebuilt, formed or patched to the engineer’s detail.
For active leaks through walls, slabs and joints, we use hydraulic cement to stop running water and injection to seal the crack. The engineer chooses the injection material based on whether the crack is structural or a water leak. Crack injection in Toronto garages and buildings always follows that choice.
Spalling, scaling and exposed rebar on curbs, stairs, walls and other garage concrete. We bring the concrete back to sound condition so it keeps doing its job.
The same repairs on commercial and industrial buildings: spalled columns and walls, damaged slabs and concrete floors, and cracks that need injection. We work to the engineer’s spec and agree the work areas and hours with you before we start.
Condo corporations and their boards, property managers, owners of rental apartment buildings with low-rise and mid-size parking garages, and owners and managers of commercial and industrial buildings in Toronto and the GTA. We also work with the restoration engineers who write the repair specs and run the tenders. We take on repair work across Toronto, Mississauga, Hamilton and the rest of the GTA. Send us your spec and drawings and we’ll price them.
How it works
We are a Toronto concrete contractor with our own crews, our own forms and our own rebar supply: the same crews who pour our concrete footings and foundation walls. When a column or a slab bay needs rebuilding, we don’t have to wait on another trade to form it or pour it. One company does the work, and one contact runs the job.
Columns, slabs, ramps, walls and leaks. Our own crews, phased around your residents. Email info@gssl.ca.
Yes. We repair columns, suspended slabs, ramps and foundation walls in low-rise and mid-size parking garages for condos and rental buildings across Toronto and the GTA.
For structural repairs to columns, slabs and ramps, yes. The engineer sets the repair areas, the rebar treatment and the materials. For smaller leaks and cracks, we can start with a site visit.
Usually, yes. We split the work into zones and close one at a time, and we agree on the schedule and the resident notices with your property manager.
Yes. In garage and building walls and slabs we stop running water with hydraulic cement, then inject the crack to seal it, with the material the engineer specifies.
Yes. Send the tender documents and we’ll price every item on the spec’s form.
It depends on the repair quantities, how deep the damage goes, the shoring, access and the phasing. Send the spec or book a site visit and we’ll give you a clear, line-by-line price.
