Geofill for firming up unstable soil or heightening and widening embankments or constructing bulwarks. With increasing road traffic and a sharp rise in delivery traffic with heavy vehicles, the burdens on roads have increased enormously. Today, planning new thoroughfares or reconstructing existing ones entails considerable challenges. More than ever, in this connection, planners have turned their attention to the lightweight construction material expanded clay.
Thanks to a high proportion of entrapped air voids, expanded clay impresses with a very low density and simultaneous high compressive strength. Expanded clay can be spread easily over a large area and requires no compaction. Beginning with a minimum installation thickness of 0.3 m, professional compaction is required. The most important effects include the firming up of the subsoil and very low settlement after loading. This also applies to differential settling in embankments and ramps.
Expanded clay is a sustainable natural product
Made from the raw material clay, expanded clay is an extremely versatile natural product. In road construction, there is no need to worry about burrowing animals or temperature fluctuations, because expanded clay is absolutely neutral and impervious. Moreover, it evidences impressive resistance to oils and salts, acids and alkaline solutions or organic solvents. Likewise, expanded clay is not attacked by carburettor substances and fuels.
There is an exceptionally wide range of potential applications. We will be happy to advise you personally about applications or particle sizes and can supply the product to you in expedient units from bags to entire vehicle loads.
