ICF 101: How Insulated Concrete Forms Work

Suspended Slabs: In-Place vs Precast
When a poured-in-place slab beats precast panels, what shoring is for, and why the engineer’s stripping schedule is not negotiable. Plus: when to choose InsulDeck® insulated stay-in-place forms instead.

FAQ · ICF
Questions we hear every week
Is ICF worth the extra cost?
For most owners, yes — as a package. You pay more for the wall, then save on heating and cooling every year, and you never pay for rot, pest or storm repairs. Ask us for an assembly comparison on your specific build; the payback math is very project-dependent.
Can ICF walls go below grade?
Absolutely — many homes use ICF for the basement walls, then frame above. The foam insulates the below-grade wall, and the concrete core handles the earth load. Waterproofing and drainage still apply, and we coordinate those too.
What does “certified installer” mean?
It means our crew leads have completed manufacturer-recognized ICF installer training and documented supervised pours before running walls on their own. Ask us for the training records — we keep them in the project file.
Can we buy the blocks ourselves and hire you to install?
Yes — install-only is a common arrangement with builders. Many clients also buy through our store at trade pricing, which simplifies warranty and material coordination.
How long does an ICF wall take to pour-ready?
Depends on size and complexity, but a typical house envelope is stacked, braced and ready in days, then poured in a day. We’ll give you a day-by-day schedule with your quote.
FAQ · Suspended Slabs & Decks
Elevated concrete, explained
What exactly is a suspended slab?
Any horizontal concrete slab that is supported above the ground — a floor over a basement, a second storey over a garage, a deck over a walk-out. It’s “suspended” because it spans between supports instead of sitting on grade.
Why use conventional formwork instead of precast?
Precast panels need crane access and standard geometry. Conventional forms let us build any footprint on any site — including tight Halton renovations — with one crew handling everything from forms to finish.
Who designs the shoring?
A licensed engineer provides or reviews the shoring layout for every elevated pour we do. We build exactly to that drawing and keep it on site for inspection — that’s the non-negotiable part.
How long before we can walk on / build on the slab?
Two different questions! Light traffic can usually happen within days, but formwork and shoring stay in place until the engineer’s stripping criteria are met — typically a couple of weeks for residential spans. We schedule around your build.
Can a concrete deck really replace a wood deck?
Yes — for a walk-out or ground deck, a poured slab is the “forever” option: no boards to replace, no rot, no annual staining. We build the drainage, insulation and finish details so it performs like an outdoor room, not a sidewalk.
Can an elevated slab be insulated too?
Yes — two routes. With conventional removable forms, insulation and thermal detailing are built into the assembly at the slab edges and underside. Or, where the design calls for an insulated slab assembly (an addition floor over a garage, a walk-out deck), we install InsulDeck® — an insulated concrete forming system for floors, roofs and elevated slabs that stays in place after the pour as insulation, chase space and finish backing. The manufacturer cites minimal shoring, no form stripping, clear spans up to roughly 33 ft for typical residential loads, and radiant-heating compatibility. We confirm Ontario availability and engineer the assembly before quoting. See our InsulDeck® explainer →
