Abstract : The invention is a method of supplying buoyancy to a sunken object using a water emulsified polyester resin and hollow microspheres. What is claimed is: A method for supplying buoyancy to a sunken object, which comprises: mixing water, a water emulsified polyester resin, catalyst and hollow glass microspheres; pumping the resulting mixture through a single hose while in the uncured state to any ocean depth; injecting the mixture into a sunken object to displace a volume of seawater substantially equal to the volume of said mixture at sea level; and, allowing the mixture to cure into a rigid material whereby said glass microspheres are rigidly suspended within the unfoamed cured polyester resin.
