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 (28). 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 comprising an envelope (50, 52) defining an internal chamber that contains a mass of buoyant macrospheres (10) each with an external diameter of at least 5mm, packed with a packing factor of at least 50%.
