Dome Construction
The dome consists of a
pre-tailored polythene membrane, which is anchored
both around the
perimeter to a concrete foundation, with a network
of plastic coated wire ropes covering the membrane,
and also to the foundation. The wire
rope network relieves the membrane of most of the
stresses and strains when the structure is inflated
by a fan that is located outside the dome.
Dome Foundations
A continuous concrete
ring beam is required, size approximately 75cm x
75cm (2' 6" x 2' 6"), grade 20-25 N/mm˛ concrete,
surface to be trowel finished to facilitate air seal
with polythene membrane. The anchor fittings are
drilled into the concrete after it has set (left
picture).
Ground Anchors
If ground conditions
permit, we can install a series of Ground Anchors
(right picture) instead of a concrete ring beam.
This is ideal where a dome is being added to
existing courts. The disruption of digging a trench
and getting rid of the soil is avoided, and costs
are slightly less than a ring beam.
