Sealing Devices must be ordered separately, see below.

This fully automatic apparatus is designed to carry out water permeability tests on concrete cube specimens up to 150mm and cylinder specimens up to 160mm diameter. The specimens are submitted to hydrostatic stress for a pre-set period. The water permeated through the test specimen is directly collected and measured into a graduated cylinder. It is therefore possible to determine the permeability coefficient in cm/sec. (Darcy coefficient) by the following formula: The equipment consists of a strong metallic frame holding four cells which are hot-galvanized for anti-corrosion protection. Each cell includes a pressure control manometer. A re-chargeable compensation plenum chamber is included as part of the test.

The pressure is adjustable from 0 to 30 bar. Pressure is supplied by an automatic pump of variable supply, to achieve the most suitable installation for the specimen under test. Water feed is direct from water inlet. Seal pressure is obtained through special and practical seal devices, which maintain and simplify the use of the machine. It is possible to use one or more cells together. The specimen’s sealing system is achieved through a practical and speedy, user-friendly device.
