How House Construction
The floor of the garage is a 4-inch-thick concrete slab poured very late in the
process. Four inches of gravel were placed on the ground and covered with plastic
and reinforcing wire. Around the edges, half-inch thick homosote will allow the
slab to contract and expand with temperature changes. Once the prep work was finished,
a concrete truck came and poured about 7 cubic yards of concrete to create the slab.
