Permeability Moulds
100mm and 150mm diameter steel moulds complete with aluminium permeability bases with inlets and outlets, porous plates, surcharges and loading plates. The 100mm diameter mould is supplied with a sample confinement clamp. The moulds are designed to facilitate the compaction process by using Geo-Con Type A compaction or CBR mould bases and collars, which are included.

Mould Preparation
Waxing equipment for the application of a thin layer of paraffin wax to the inside of the moulds, to prevent piping of water between the mould and specimen. The moulds are mounted inside the wooden jig then placed on the roller mill. The roller mill rotates the mould allowing an even and consistent application of the molten wax with use of the waxing funnel in its stand.
