For the use in both extracted soil or in situ where ASS may or may not be present and is particularly suited to the stabilisation of soils that are soft or peaty. The PMX 500 system is a purpose built mixing device that is fitted to an excavator. As holes are drilled into the soft substrate, cement or lime is mixed with the soil slurry to form solid supportive columns, when the cement sets. Particularly suited to pipe laying through environmentally sensitive areas such as estuarine, salt lakes or mangrove locations.
Deep soil mixing has been used in Scandinavian countries for many years for construction on peaty soils, and the technology is now being adopted in many other parts of the world. DWER GUIDELINE 2015 Treatment and management of soil and water in acid sulfate soil landscapes.
