Celebrating America’s 250th Anniversary (1776–2026)
When to use
Usual start for pipe abandonment. The lightest published Volume cellular fill — 27 PCF, about 82% foam, ~107 psi. Same 108 PCF neat-cement base slurry as the rest of the cellular family. Annular space, abandoned pipe, void fill, and low-pressure foundation backfill.
Most pipe abandonment starts at 27 or 33 PCF. Use 38 or 45 PCF only when the engineer specifies higher strength or density. Size the fill with the Pipe Abandonment Calculator.
