UPDATE 3: Foundation
Pouring The Addition Frost Footings
Concrete frost footings will support the new Addition’s foundation. Minnesota’s climate, with frigid winters and hot summers, can cause the ground under the foundation to shift. Pouring footings below the frost line helps prevent soil movement called frost heave. The footings also prevent settling that could damage the new structure. Concrete is poured into wooden forms to create the footings. Once the footings have set, we can lay the foundation block.
Laying The Foundation Block
Block, also known as CMU (concrete masonry unit), is used to build the foundation walls. A waterproofing layer is applied to the block, making it look like it’s been painted black. Next, rigid pink foam insulation is installed on the foundation exterior, and reflective sheathing foam insulation lines the interior. Once the foundation is finished, we’ll be ready to start framing the new Addition.
