quick overview :

• Sand table, 300mm diameter
• Sliding suction control chamber giving tension range 0-800mm of water (using sandy-loam)
• Complete with three soil sample retaining rings (80mm diameter), instructions and manual.

Description:

These equipment consists of a free-standing circular tank filled with saturated sand (not supplied). Equilibrated soil samples placed on the sand are then subjected to a known variable suction range of 0- 800mm of water. The suction is applied by means of a buried porous pipe and an associated sliding control chamber. In order to maintain the suction an uninterrupted low volume water supply is required.

A lightweight cover is provided to prevent evaporative water loss during experiments and the table is large enough to permit the simultaneous evaluation of several samples.
