Sika-Trocal supplied
the waterproof solution for a multiple roof installation at a high-end care
home development which was stunning in appearance, performance and complexity.
The Hawthorns is a
new, all-inclusive, luxury retirement community complex designed to encourage
activity and independence in its residents.
The four-storey
building located in Northampton is an exemplar in style and practically, hence
the need for a high-quality roof which enhanced the property’s aesthetics and
offered optimum, long-term waterproof protection.
In order to achieve
this, contractors, Ithaca Roofing, installed Sika-Trocal’s Type ‘S’ system to
the building’s two main roofs which covered a 2,300m2 area. Aided by the membrane’s light, easy-handling ability,
installers worked quickly and concisely to minimise disruption to other nearby
trades and avoid project delays. This required implementing the highest safety
standards to eliminate the potential for on-site injury.
Initial
waterproofing works involved the installation of “loose laid” Sika-Trocal S-VAP
500E, a vapour control layer based on Polyethylene, to the building’s
substrate.
As well as
installing waterproofing to the roof’s main body, Ithaca fitted its 1.5-metre
parapets. This presented a challenge, as each huge section had to fit precisely
in order to create a crisp, uniform finish to the building’s edges. A man-safe
rail was also installed to ensure future roof inspections or maintenance can be
carried out without incident.
The project’s
complexity was enhanced with the inclusion of six balconies, two terraces and a
car park podium. Each required a high-quality waterproof system in the form of
Sika-Trocal SGmA, ballasted roof waterproofing membrane build-up and
paving finish.
Lee Dunking, Single
Ply Manager at Ithaca Roofing, said: “The retirement community complex is a
superb, high-end development. It therefore required a quality waterproof roof
system to match.
"With its
easy-handling ability and well-founded reputation for offering long-term
weathertight protection, Sika-Trocal’s Type ‘S’ system proved the ideal
solution for this project. Our installation team enjoyed working with this
excellent system; our clients are delighted with its look and performance.”
In total, 3,000m2 of waterproof roofing was installed
during the Hawthorns project. The installation - despite its complexity - was
competed ahead of the client’s deadline; with Ithaca’s workmanship, combined
with the quality of the Sika products used, ensuring the retirement community
complex opened on schedule in summer 2018.
