Pouring The Foundation Frost Footing

It’s time to build the new addition foundation! Freezing Minnesota winters and hot summers can cause the ground under the foundation to shift. Concrete is poured into a wooden form to create frost footings to support the new addition. Building the footing below the frost line helps prevent settling and soil movement called frost heave that could damage the new structure. Once the concrete is set, it’s time to lay the block.


The excavated area is prepped with wooden forms for pouring the frost footings.

Laying The Block

Masons lay the CMU (concrete masonry unit) block to create the foundation walls. Then a black sealant is painted on the block, creating a waterproof layer. Next, rigid pink foam insulation is added to the foundation exterior. Once the foundation is finished, framing can start.
