The dimensions of ground containment structures are determined by the horizontal thrust of the contained ground. Expanded clay is particularly useful as a replacement for traditional aggregate fill behind existing or new containment structures, because it reduces the thrust and offers various other advantages.
Advantages
Thermal insulation in earth retaining walls
In addition to the advantages mentioned above, Laterlite Expanded Clay also gives effective thermal insulation (lambda value 0.09 W/mK) in earth retaining walls that surround habitable rooms, tanks, or swimming pools.
For effective additional protection against damp in these types of application, it is advisable to use special Laterlite Plus hydrophobic expanded clay, if necessary in conjunction with TermoBag modules. For further information, see the specific documentation.
