Celebrating America’s 250th Anniversary (1776–2026)
When to use
The densest published Volume cellular fill — 45 PCF, about 69% foam, ~230 psi. Same 108 PCF neat-cement base slurry as 27 / 33 / 38. Annular space, abandoned pipe, void fill, and foundation backfill when the spec wants more unit weight.
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.
