Bloxx Foundations is York Region's dedicated ICF (Insulated Concrete Form) foundation contractor. We do one thing — and we do it right.
ICF is the modern standard for residential and commercial foundations — stronger, better insulated, and built to outperform traditional poured concrete in Ontario's climate.
Reinforced concrete walls that exceed building code requirements and stand up to Ontario's freeze-thaw cycles year after year.
ICF delivers dramatically higher R-values than poured concrete or block, cutting heating and cooling costs for the life of the building.
Continuous insulation reduces moisture migration and lowers the risk of water intrusion — a critical factor in York Region's climate.
Custom home builds, multi-unit residential, light commercial — ICF performs across all project types.
The ICF systems we work with are manufactured in Canada. No tariff exposure — reliable pricing and consistent supply.
Forms stack quickly and stay in place after the pour — your framing crew gets on site sooner and your schedule stays on track.
We work with two of the most trusted ICF systems in the industry — both manufactured in Canada, both proven on job sites across Ontario. No imported materials, no supply chain surprises.
Nudura is the industry benchmark for ICF construction — the largest ICF block in North America at 8’ × 18”, meaning walls stack faster than any competing system. Their patented Duralok technology locks webs together vertically, eliminating form uplift and settlement during the pour. Made in Canada at facilities in Ontario, Quebec, and Alberta.
Amvic has been manufacturing ICF in Canada since 1997. Their patented FormLock™ interlock system delivers the highest independently tested forming capacity strength in the industry — 865 lbs/ft² per the Canadian Construction Material Centre (CCMC). The 5-in-1 system combines structure, insulation, air barrier, vapour barrier, and finish attachment in a single form. Headquarters in Toronto, Ontario.
Real projects, real pours. Follow along on Instagram as we document what goes into getting a foundation right.
Straightforward. Methodical. No guesswork — just a proven process that gets your foundation right the first time.
We visit the site, review the drawings, and give you a straight quote. No runaround, no surprises.
Footings are formed and poured to spec. The base has to be right — so we make it right before anything goes on top of it.
Forms are stacked to height with rebar placed to structural requirements. Precision at every course.
Wall systems are braced and laser-checked for plumb and alignment before any concrete is placed.
Concrete is placed in controlled lifts, vibrated thoroughly, and monitored for the full pour duration.
Bracing comes off, the work gets inspected, and we hand off a foundation that's ready for the next trade.
If you're a custom home builder or GC working in York Region, this section is for you. Here's what working with Bloxx looks like.
We don't do concrete driveways, flatwork, or general construction. ICF foundations are the only thing on our plate — which means we're very good at them, and we're available when you need us.
We block our calendar for your job, show up when we say we will, and flag issues early — not after they've become your problem. Your schedule is our schedule.
Every person on our crew works ICF full-time. No learning curve on your job site, no unfamiliar systems, no "we usually do poured walls" conversations mid-project.
The foundation we leave is inspection-ready and frame-ready. Plumb, braced, and finished exactly the way a framing crew expects to find it.
Single-family custom homes, semi-detached, townhouse blocks, multi-unit residential — we work across project types and scales. Residential and commercial both.
Whether you're building a custom home in Aurora or a commercial foundation in Bradford, our crew handles the scope. We're familiar with both OBC residential and commercial requirements.
We're based in and focused on York Region. Newmarket, Aurora, Stouffville, East Gwillimbury, Bradford, Keswick — these are our home markets and we're on job sites here regularly.
York Region-based and York Region-focused — with reach into surrounding municipalities. If your project is within range, we likely cover it.
