Foundation to finish since 2007.

One contractor. Every trade.

Founded in 2007, Poseidon Concrete started with a simple premise: homeowners shouldn't need five different contractors to build a foundation, waterproof it, pour a driveway, install a septic system, and finish with masonry. One crew with the right equipment and expertise should handle it all.

Nearly two decades later, that premise hasn't changed. We still show up with our own equipment, our own crew, and our own accountability. No subcontractors. No finger-pointing. One contractor from first shovel to final finish.

We're BCIN licensed for septic systems, WSIB certified for workplace safety, and carry $5M+ in liability insurance. We serve the entire GTA and communities up to 150km from our Woodbridge base.
