Abstract

A method and a resulting PLDCC slab formed by that method results in elevating the lowest floor (LFE) of a proposed structure to be built on a selected building site to a height at or above the base flood elevation (BFE) as each term is defined under 44 CFR 60.3. The BFE is retrieved from the Flood Insurance Rate Map (FIRM) by locating the building site thereon. The proposed structure defines the LFE. With a height of the existing grade beneath the LFE, a difference between the BFE and the height of the existing grade beneath the LFE determines a PLDCC height. A form constructed to contain a volume of cellular lightweight concrete (PLDCC) having a PLDCC height that equals the difference. A pour of sufficient PLDCC volume then fills the form to a depth at the LFE equal to or exceeding the PLDCC height.

Dependent claims

The method for elevating the lowest floor elevation (LFE) of a proposed structure to be built on a selected building site on an existing grade to a height at or above the base flood elevation (BFE) as each term is defined under 44 CFR 60.3, the method comprising:

determining the BFE from the Flood Insurance Rate Map (FIRM) by locating the building site thereon and retrieving the BFE;
determining, based upon the proposed structure and the LFE the proposed structure determines;
determining the height of the existing grade beneath the LFE;
calculate a difference between the BFE and the height of the existing grade beneath the LFE;
constructing a form to contain a volume of permeable lightweight cellular concrete (PLDCC), the volume having a PLDCC height that equals the difference;
and
pouring sufficient PLDCC to fill the form to form a PLDCC slab, the PLDCC slab having a depth at the LFE equal to or exceeding the PLDCC height.
