.3.3 Loadings:
If the tank is installed in an area where traffic or other superimposed loadings can be applied, consult a
structural engineer for the design of a reinforced concrete slab to prevent the load being transmitted to
the tank (or its concrete surround). If this slab is constructed immediately above the tank, it should
be separated from the concrete surrounding the tank by a compressible material. Installation guidelines
are available on www.ie.tricel.eu.
10.3.4 Control of groundwater:
During installation tanks must not be subjected to buoyant
forces.
Incorrectly installed tanks that are subject to movement, rotation or floatation may become damaged,
for which we cannot accept liability.
Contact a qualified engineer if there are difficulties on site due to adverse water
logging.
10.4 Gravel installation:
A gravel surround can be used in dry site conditions if the inlet invert is less than 810mm (maximum
250mm riser).
A dry site is one where the water table never rises higher than the base of the Tricel
Duos tank.
