A buoyant, nonabsorbent, high-strength, low-density, bulk filler material which can be readily mixed and cast for use in the displacement of sea water at great ocean depths. The material of varying pellet-size is formed by dropping epoxy resin into a bed of microspheres under ambient conditions. The droplets absorb the microspheres thereby forming uncured pellets, the size of which is controlled by the size of the droplet. They are then cured for several hours at an elevated temperature.
