Prefabricated permanent formwork structure
Prefabricated permanent formwork structure 10, for forming a pit, comprising a vertical side wall 16 around the periphery of a base 12 and having an outer layer 18 extending from the base and an inner layer 20, with a space between the inner and outer layers defining a first cavity, a floorpan spaced above the base and extending between the inner layer to define a chamber of the pit, the space between the floorpan and base defining a second cavity, wherein concrete can flow from the first cavity into the second cavity and when set the concrete and the formwork form a unitary wall and base of the pit. The first cavity may have a strengthening element 34 in the first cavity about a corner in the outer layer coupled to the outer layer on either side of the corner along its height. The side wall may be formed from a plurality of modular wall elements 28 each having an outer wall portion and an inner wall portion, and a plurality of modular corner elements 30 each having an outer wall portion and an inner wall portion. The formwork may be for manholes, draw pits, or inspection chambers.
