Claims21
-49. (canceled)
A pressure resistant material for use under submerged conditions, said pressure resistant material shaped in one or more blocks covered by one or more membranes of very low permeability to water, comprising
- porous mineral beads of light expanded clay agglomerates,
- said porous mineral beads being generally of rounded or spherical shape and having a diameter of 1 to 8 mm and distributed in a matrix of a polymer material,
- said porous mineral beads generally not in bead-to-bead contact,
- wherein all porous mineral beads near an outer surface of said material are entirely enveloped by said matrix,
- said pressure resistant material withstanding a hydrostatic pressure of 200 Bar or more for 1000 hours.

A method of manufacturing a pressure resistant material for use under submerged conditions, comprising
- providing porous mineral beads of light expanded clay agglomerates in a polymer material;
- forming a matrix of said polymer material, said matrix enveloping each and all of said porous mineral beads, said porous mineral beads generally not in mutual non-bead-to-bead mineral contact,
- forming said pressure resistant material in one or more blocks,
- consolidating said matrix with said porous mineral beads to form said blocks of pressure resistant material
- covering one or more of said blocks of said pressure resistant material with one or more layers of water resistant membrane.
