Set over 48 acres, Cargiant at East Lane Business Park is London’s largest used car showroom, holding an impressive 6000 cars in one location. To keep the vast number of cars protected, an effective waterproof rooﬁng system was needed for the new build showroom. However, due to the thick insulation and concrete deck on the roof, a traditional mechanically ﬁxed system was not possible, meaning a durable alternative needed to be found.
SW Rooﬁng Solutions Ltd was tasked by main contractors London Cost Ltd with the speciﬁcation and installation of the rooﬁng system. As specialists in ﬂat rooﬁng, SW Rooﬁng Solutions Ltd’s extensive knowledge meant they were able to recommend the best solution to the architect.
Sika Sarnaﬁl® G410-15 EL SA membrane was suggested, as the product would provide an effective and robust solution without the need for mechanical ﬁxing. The new innovative membrane combines Sarnaﬁl’s tried and tested BBA-certiﬁed single ply membrane with new self-adhesive technology, delivering a unique ‘peel and stick’ rooﬁng solution.
The quick and easy-to-apply system proved ideal for the project. Faced with delays from earlier in construction, Sika Sarnaﬁl’s G410-15 EL SA membrane’s ease of use helped to bring the project back on schedule. In fact, the project eventually ﬁnished ahead of time due to the rooﬁng contractor’s skill and product’s quick installation.
Upon successful completion of the installation, the project secured a 15-year Sika Sarnaﬁl guarantee due to the high quality ﬁnish and workmanship throughout. The client was happy with the end result, so much so that they now intend to use the same rooﬁng system across another six to seven further locations as they expand.
