5.2.3 Installation adjacent to surfaces used by
vehicles
If the underground tanks are installed adjacent to
surfaces which are used by heavy vehicles weighing over
3,5 t, the minimum distance away from these surfaces is
at least the depth of the trench.
5.2.4 Connection of several tanks
Two or more tanks are connected via the
assembly surfaces by means of GRAF
special seals and basic pipes (to be
provided at construction site).
The apertures must be drilled to the
corresponding size using only the GRAF special crown bit. It must be ensured that the distance between
the tanks is at least 500 mm. The pipes must project at least 200 mm into the tanks.
