A new synthetic waterproofing
installation method is launched
The installation of synthetic waterproofing membranes is now easier than ever, thanks to the
RhinoBond attachment system which is designed for TPO and PVC membranes. Soprema explains how
Regarding the installation of synthetic
waterproofing membranes (commonly
referred to as single-ply membranes),
there are many installation methods
available for these systems: e.g. fully
adhering with glue adhesive, mechanically fixing,
loose laying with welded laps and ballast.
For some time, there has been a demand for a
synthetic waterproofing installation method that can

fast-track the waterproofing installation and increase
security for large-scale commercial projects.
An alternative to traditional synthetic
membrane fixing methods has been developed,
tested and launched in the UK waterproofing
market by Soprema. RhinoBond is an
alternative insulation and membrane attachment
system for TPO and PVC membranes. The
system uses the same fastener and plate to
secure both the insulation and the waterproofing
membrane to the deck, without penetrating the
The result is a system that does not create
any point of entry for moisture, requires fewer
fasteners (from 25-50% compared to traditional
mechanically-fixed applications) and provides
superior wind uplift performance.
RhinoBond is based on patented electromagnetic
induction welding technology. Just place the
RhinoBond tool on the membrane, directly over
the specially coated plate and activate it to bond
the underside of the membrane to the plate.
There are no side-lap fasteners required with
the RhinoBond system. Since the fastening points
are spread across the entire roof in a grid pattern,
the uplift load is distributed more evenly, and the
system can achieve higher wind ratings with fewer
fasteners compared to other fixing methods.
Combined with the Flagon single-ply
membranes by Soprema, this system guarantees
security and peace of mind for the client,
whilst providing significant performance and
The Rhinobond induction fixing method is
fully approved by Soprema and has been through
rigorous testing with Flagon membranes.

IKO and Sussex Asphalte scoop
roofing award for St Paul’s Cathedral
Last month, IKO and Sussex Asphalte
scooped the Best Mastic Asphalt Project
award at The UK Roofing Awards 2018
for their work on the Stone Gallery in St
Paul’s Cathedral in London.
The NFRC ceremony, which took place at
the Park Plaza hotel in Westminster on May 11,
2018, celebrates outstanding standards of design
workmanship and safety in the industry, and the
work on the Stone Gallery was a prime example.
It is the first of two galleries above the
Whispering Gallery that encircle the outside of
the dome of the cathedral. At 53 metres high, the
gallery’s exposure to the elements and surface
deterioration had caused water ingress damaging
artwork inside the dome.
Sussex Asphalte replaced the asphalt
originally laid in 1906 with IKO Permaphalt, a
specially formulated, polymer-modified mastic
asphalt. Works were phased to ensure continued
public access and the asphalt was stripped and
re-laid in sections to ensure watertightness – as
the asphalt provides a seamless installation.
During the process a disused stairwell was
revealed, which remains as a feature, having been
made safe by the contractors.
The gallery includes a central gutter covered
by iron grills that were removed, cleaned and
refitted on the new asphalt. To ensure the correct
width of asphalt was applied, a gutter template
was fabricated and used as a guide by the
asphalters, requiring skilled precision work. Other
detail work involved adjustments to rainwater
outlets to improve drainage, and vertical upstand
into a chase, including a double angle fillet around
the galley’s circumference – 286 linear metres!
The height and highly sensitive fabric of the
building meant that all materials were transported
to the gallery via three hoists, requiring careful
operation and management.
