Traditional aggregates used as fill above underground structures (tunnels, parking garages, etc.) impose a high permanent load that restricts the possibilities of re-using the existing structures and requires new structural elements to be oversized to take the extra load.
The construction of lightweight fills and embankments on underground structures with Laterlite Expanded Clay drastically reduces the weight of the fill layers, and its high strength enables maximum flexibility in how the spaces above are used.
