    Under-slab closed-cell spray foam for heated floors and frost protection on Winnipeg new builds and additions. Installed before the concrete pour.

    Under-Slab Spray Foam. Green Home Insulation

    Under-slab foam goes down before the concrete pour. It creates a continuous insulation layer under heated floors and helps protect slabs from frost heave at grade in Manitoba soils.

    Timing matters. We coordinate with your builder so the foam is in place when the slab schedule opens. Talk to us early if you are planning an addition or new shop.

    Insulation before the pour

    Once concrete is poured there is no going back, so under-slab insulation has to be part of the plan from the start. The foam forms a continuous layer under the slab, with edge details where the slab meets grade.

    Under-slab work is schedule-driven. The foam has to be down before the slab crew arrives, so we treat your pour date as the deadline and plan the job around it.

    Heated floors and frost protection

    Under-slab and edge insulation details are planned with your builder.

    Radiant and heated floors

    Insulation under a heated slab keeps heat going into the room instead of the ground. It is strongly recommended for radiant heat.

    Frost protection

    Under-slab and edge insulation details help protect slabs from frost movement at grade in Manitoba soils.

    Talk to us early if you are planning an addition or new shop so the foam is scheduled before the concrete.

    Working with your builder

    We coordinate with your builder so foam is down when the slab schedule opens. Share the pour date as soon as it is firm.

    New builds and additions

    Under-slab foam is common on new builds and additions. If you are also planning rim-joist or wall foam, ask us what sequence makes sense for your project.
