Pupils at a South
East London school can now enjoy sport at height thanks to the timely
completion of a rooftop ‘multi-use games area’ or MUGA.
Flat roof specialist
Byford Roofing tackled the job knowing that the installation was complex and
demanding but also that the schedule was tight.
Byford chose BMI
Icopal’s Parabit Holt Melt Duo that it applied to the concrete deck of the
roof. Over that went a layer of inverted insulation and paving slabs ready to
receive the MUGA pitch finish.
“I chose Parabit because it’s a system we know
well, we’re comfortable laying it and therefore it gave us confidence in
achieving the target programme completion date. Not only is it suitable for a
zero falls roof, it is also very robust,” explained Andrew Byford, Director at
Byford Roofing.
He added: “Because
of the limited storage space on site, we needed to get the hot melt laid as
fast as we could so that we could use the roof area for storage of the other
roofing materials. That meant it also had to be tough enough to cope with
movement of people and materials around it.”
From an installation
perspective, the most challenging aspect for Byford Roofing was ensuring that
it provided a totally flat surface for the application of the sports surfacing.
This meant accuracy in installing the insulation layer and the paving slab ballast.
“It had to be completely level to ensure the MUGA could be laid to the correct
tolerances,” said Byford.
To ensure the
contractor met that requirement, Byford chose a paving support system that
offered minimal build up with the most support. “After that it was all about
making precise cuts, taking time to get it right and achieve that level
finish,” he continued. “We increased our labour on site to include the highest
skilled operatives to make sure we did that.”
Most of the 800m2 roof area was applied in an initial
period of two-to-three weeks. Beyond that, Byford made return visits to site to
work with the sequencing of other works by the main contractor. One of the
later tasks was waterproofing with BMI Icopal Elastoflex around the fence posts
that had been installed into the waterproofed parapet wall around the roof’s
perimeter.
Given the demanding
nature of the contract, Byford was pleased with the result. “I was happy with
the spec we put forward,” he said. “It has worked well and it enabled us to
complete the project on time and within budget. Working with materials that we
trust such as BMI Icopal Parabit Hot Melt Duo, helped us achieve a really
satisfying outcome.”
