Why GSS
01
We own our forming system, so your pour never waits on a rental yard or another crew’s calendar.
02
Concrete and framing under one contract. No gap between trades, and no arguing over walls that are out of square.
03
Built to your engineered drawings. Footings are inspected before every pour, and underpinning follows the engineer’s sequence.
04
WSIB cleared with $5 million in liability insurance. Certificates on request, before we start.
A basement floor is only as good as what is under it. We prepare the base, vapour barrier and insulation your drawings call for, handle the under-slab plumbing, and pour a level floor the next trade can work on.
No waiting on rental stock or another crew
