A method of filling a chamber with buoyant macrospheres 10 comprises placing a mass of the spheres into a mould cavity 24. In the mould cavity, packing of the spheres is optimised to form an optimally-packed mass, followed by fixing the spheres in the optimally-packed mass to form a block. The block is then transferred from the mould cavity into the chamber while the spheres of the block remain fixed in the optimally-packed mass. This method enables the production of a buoyant element (54, Fig 12) comprising an envelope (50, Fig 12) defining an internal chamber that contains a mass of buoyant macrospheres each with an external diameter of at least 5mm, packed with a packing factor of at least 50%.
