Geofill LD Marine cellular (foam) concrete is specifically formulated for use in underwater placement applications. Geofill LD Marine is a lightweight, low permeability material which remains in a cohesive, well blended mix when placed or pumped into a submerged environment.

This lightweight, low permeability material effectively displaces water, does not segregate, is highly flowable and is designed to resist wash-out in underwater or tidal zone applications.


Geofill LD Marine offers several advantages, especially underwater:

  • Lightweight, but heavier than water
  • Low permeability
  • Displaces water effectively
  • Will fill small or hard to reach voids
  • Extremely flowable and pumpable
  • High Bearing capacity
  • Protect timber piles from marine organisms
