Soil compactors

Martens en Van Oord has two different types of soil compactors: smooth rollers and padfoot drum rollers. Both types are used to achieve the right level of compaction for certain types of material, one for sandy soil and crushed rubble, the other one for clay soil. 

Smooth rollers are used to compact foundation layers of roads and (sand) cores of dykes. 

Padfoot drum rollers can be used to compact clay soil. A padfoot drum roller has tractor tyres (highly profiled), allowing it to manoeuvre well in clay soil.
