How it goes in
No poured footer below grade
A buried vault sits on a bed of crushed, compacted stone — no footing to form, pour or wait on. A building set above ground requires a poured footing, so frost can't shift it.
Sealed and watertight
Every panel seam is sealed with polyurethane and through-bolted. The structure is watertight once the last seam closes.
Grouted, then backfilled
On a buried kit, the precast floor sections sit inside the walls with a small gap all round. The gaps are grouted solid before any backfill goes in.
If your building department needs stamped plans, our engineer seals your layout once you have signed off on the drawing, with the structural calculations attached. His stamp covers the states he is licensed in — tell us where you are building, and we will say what your soil, frost depth or seismic category adds.
Questions about this kit
Why is the hatch priced separately?
The access hatch is set on site by Freestone, so it is quoted with your job. The price shown covers the wall and corner panels, the precast lid and the floor sections.
Can it be bigger?
Yes. Length steps in 4 ft panels and clear height comes in 8, 10 or 12 ft. Size one in the configurator and it lists every part it can count, with the rest confirmed on your quote.
Can it be waterproofed?
Yes. Waterproofing is available per panel on any buried kit except the cellars, which need their humidity.
