With the aid of water the Philippi sand is forced through 3.2mm aperture screen to ensure that all vegetation is removed. Although the clay/silt content is naturally below the 3% cut-off for the concrete envelope, the washed sand in essence contains no clay/silt. This is the purest form of Philippi sand available.
