The foundation is prepared by your local contractor before our panelised package arrives on site. There are several types of foundations for you to consider - slab on grade (pre-engineered concrete), full depth basement, crawlspace or pier foundation.
Slab on Grade
In areas where basements are not common or required, a concrete slab is a common alternative. Concrete slabs require local engineering to account for soil conditions. Walls can be easily anchored to the slab using poured-in-place anchors, chemical or mechanical fasteners. A foam gasket is used between the bottom plates and the concrete in order to prevent moisture wicking into the wall panels.
Full Basement / Crawlspace
Full Basements and Crawlspaces are essentially the same except for height. A full basement is typically eight feet (or more) in height whereas a crawlspace is usually four feet. After the foundation is complete, the sub-floor is installed before any wall panels are installed. The sub-floor process starts by installing any required columns, beams and sill plates. Next the floor joists, boxing and sheathing are installed. This brings the house to the point where it is ready for the first floor walls.
Pier Foundation
Pier foundations rely on a series of piers and beams to carry the load of the house. With a pier foundation a sub-floor is installed first before any wall panels. The process begins by installing the beams required to carry the sub-floor. The floor system follows with the floor joist, boxing and sheathing. This brings the house to the point where it is ready for the first floor walls.
