Definitions
- the filter 19 for use in a concrete press mould 10 according to a first embodiment.
- the filter 19 comprises a fabric which is knit or woven from a hydrophobic yarn 30 to produce a fabric having a density which permits the passage of water 18 therethrough but prohibits the passage of particulate material such as sand or cement 17.
- the fabric is preferably heat set, so that it retains its integrity when exposed to use in the press mould.
