This was the problem faced by the London
Borough of Hackney officials; something
was needed to protect the tree roots of
the many established trees that lined its
streets. Officials from the London Borough
of Hackney appointed Civil Engineering
Contractor Volker Fitzpatrick to solve this
problem.
The solution was RonaDeck Eco Tree
Pit, a natural aggregate finish surround
for planted trees in public and private
areas, it was recommended for its SuDS
compliance, ease of maintenance, and
for the appearance of the resin bound
gravel. Sub-contractor AJ O’Connor was
appointed to install the system which has
gradually been applied over a large area.
RonaDeck Eco Tree Pit surrounds the tree
with a resin bound aggregate surface that
is easily swept clean and has a porous
structure that allows rainwater to seep
immediately through to the root system
and reduces the burden on surface water
drainage.
AJ O’Connor excavated around each
tree to a depth of 150-200mm and filled
the excavation with gravel to within 50
mm - 75 mm of the surface, the required
depth of RonaDeck Eco Tree Pit system.
The two-part resin was mixed with a drill
and paddle before being added to the
kiln-dried aggregate component in a high
capacity forced action mixer. The mixture
was then laid on the prepared gravel base
and levelled off.
EcoPath for Golfers - Enfield
A new highly sustainable product in the
RonaDeck range RonaDeck EcoPath MT
was used to provide a slip resistant surface
for golfers waiting at the first tee at Enfield
Golf Club.
The loose gravel waiting a rea next to the
first tee at Enfield Golf Club was causing
maintenance problems; the gravel was
migrating to grassed areas and it became
muddy and slippery in wet weather, a
particular problem in the winter months.
RonaDeck EcoPath MT was specified to
provide a slip resistant, attractive, easily
maintainable waiting area for golfers and
spectators. The area also needed to be
accessed safely so the design included
a set of steps, surfaced with RonaDeck
EcoPath MT, leading down to the tee.
As its name suggests RonaDeck EcoPath
MT is sustainable, with recycled rubber
tyres being used to produce the rubber
granules. It is also porous; applied to Type
3 aggregate, the permeable construction
is SuDS compliant. As well as helping
the environment, this permeability
prevents surface ponding, an important
consideration for this project.
RonaDeck EcoPath MT was applied to
the prepared base of compacted Type 3
aggregate, levelled and smoothed with a
float. The surface was allowed to cure and
was ready for foot traffic within 24 hours.
RonaDeck EcoPath MT provided a visually
attractive and slip resistant surface for
golfers and spectators to wait on while
they watched the first shots being played.
RonaDeck systems have also been used in
sporting venues including Lords Cricket
Ground, Twickenham and Wembley.
