The Welsh National Sailing Academy and Events Centre designed by Ellis Williams Architects boasts stunning seafront architecture and design, but was a challenging build. Anglesey-based Weatherwell Roofing was contracted to waterproof the roof and walls during a winter project that required the skilful application of a variety of Sika Liquid Plastics products.

Due to the location of the sailing academy between the dunes and marina of Pwllheli, the main requirement of the architect was to achieve a striking design that could withstand the elements. Any products used on the project had to offer a flawless finish alongside durability and strength, backed by guarantees.

Sika Liquid Plastics’ liquid applied waterproofing systems fitted the bill and were specified across the building envelope. On the gabion walls, a Decothane Gamma 20 system was used, while on the concrete walls, a Sikalastic 618 15 year coating. All of the gabion walls were waterproofed down to the foundations of the building, with the liquid system seamlessly joining the walls to the roof areas. This created a 100 percent waterproof junction between the two, an extremely important factor for a building that must weather the coastal environment. In addition, Decothane has excellent elastic properties, making it UV stable and tolerant of thermal movement.

For the cold roofs, warm roofs and green roof area, totalling over 1000 square metres, Decothane Delta 25 was applied onto various primed surfaces, from concrete deck to a mix of flat board and tapered Decotherm insulation. All the roof areas were covered by timer decking for use as viewing galleries and cafe seating areas, where a Sika Liquid Plastics protective layer was also used.

Kristian Lewis, Weatherwell company manager, said: 'We completed our portion of the project in 14 weeks, despite working through difficult winter conditions. Even in low temperatures we were able to expertly apply the Sika Liquid Plastics waterproofing membranes. The liquid applied nature of the products allowed us to get a great finish, even around the more complex detailing.

'It’s great to be involved in a project that will give so much back to the local community and open the door for new sailors in the area.'

The Sika Liquid Plastics technical team were on hand throughout the project to offer expert guidance, from initial design and specification to quality control during installation and final inspection, resulting in the issue of single point guarantees.

The National Sailing Academy, commissioned by Gwynedd County Council, secured funding of more than £8 millon for its construction, in order to increase opportunities for the surrounding community and boost the local economy. The facility has been constructed to BREEAM ‘Excellent’ standards with sustainable features including biomass heating, solar panels and rainwater harvesting. Officially opened in the summer of 2015, the centre acts as a hub for national and international sailing events, as well as hosting a number of other clubs and training activities.

Decothane is available throughout the UK from Sika Liquid Plastics. For more information and technical support visit: gbr.liquidplastics.sika.com
