The planning aid can used to

for the foundation earthing system

2. Alternatively, wall penetrations sealed against
pressurised water (type RD10) should used.
Connections from the ring earther into the building
should located above the maximum groundwater
level.g.
Connections between foundation earthers/functional
equipotential bonding cables and the reinforcement,
or between functional equipotential bonding cables
and the ring earther, and with the connection lugs,
can take the form bolted joints, clamped joints or
welded joints.
