Waterside Shopping Centre: Delivering a facade transformation

In 2019 a comprehensive programme of works commenced to revitalise the elevations. The majority of the failed render, measuring approximately 1,100 square metres, was removed and replaced with weberpral M monocouche render, selected for its durability and consistent through-colour finish, complemented by PVCu render beads from Renderplas.

 

Principal contractor Barwin, a specialist in facade restoration and refurbishment with more than three decades of experience, understood that achieving a high-quality render finish depends on more than just the render itself. The detailing defines the result. Over 2,500 linear metres of beads were required across the scheme, including bellcast beads, stop beads, corner beads and movement joint beads. These components would determine the straightness of lines, the sharpness of corners and the long-term durability of vulnerable edges.

 

Although Renderplas PVCu beads were not included in the original specification, Barwin made the deliberate decision to use them. The choice was based on prior experience and confidence in their performance. Inferior beads can distort during installation, corrode over time or compromise the crispness of architectural detailing. On a prominent retail scheme undergoing complete rejuvenation, those risks were not acceptable.

 

Martin Hill, Senior Estimator at Barwin, explains the reasoning clearly: “Renderplas beads complement the quality finish of the render really well. It was a no-brainer to use them. They are readily available and don’t distort or fall apart. They also remain dead straight and give a perfect, crisp finish.”

 

His comments reflect a common challenge within facade refurbishment projects. Contractors are often asked to rectify problems caused by substandard beads that have warped, cracked or rusted, leading to uneven lines and premature failure of the render system. 

 

In contrast, Renderplas PVCu beads are engineered to remain straight and dimensionally stable while offering enough flexibility for efficient installation. Their corrosion-proof composition eliminates the risk of rust staining, and their structural integrity supports clean movement detailing and long-term facade performance.

 

Importantly, Renderplas external render beads are fully BBA certified and guaranteed for 25-years or the lifetime of the render system. This assurance provides specifiers, contractors and building owners with long-term confidence that the detailing will perform as intended without costly maintenance interventions.

 

The completed facades at Waterside now present a bright, contemporary backdrop to a revitalised retail and leisure environment. Crisp corners, sharp edges and consistent lines enhance the monocouche finish and contribute to a cohesive architectural appearance. The transformation has helped reposition the centre as an attractive, modern destination, alive with new bars, shops and restaurants.

 

The project demonstrates a fundamental principle of facade construction: long-term quality is achieved through informed material choices. By insisting on Renderplas PVCu beads, even where they were not specified, Barwin ensured that the renewed render system would not only look impressive on completion but remain reliable and resilient for decades to come. The scale of the refurbishment required careful planning and was delivered across five phases. Although scheduled for completion within six months, the works were finished in just five, demonstrating effective coordination and experienced site management.

 

In external rendering, details matter. When corners are executed correctly and movement is properly managed, the entire facade benefits. Renderplas continues to provide the construction industry with durable, BBA-certified PVCu render beads that deliver crisp architectural detailing and lasting performance, ensuring that on projects like Waterside, corners are finished precisely and never cut. 

About Renderplas

 

Renderplas was formed in 1990 to offer the plastering industry a new concept in beading. The first manufacturer of PVCu beads in the UK, Renderplas is the leading exponent in the field.

The business sets out to address the shortcomings of traditional profiles by designing a range of beads in PVCu to suit the British and Continental market. The key benefit of PVCu beads is that they use the most cost-effective, non-corrosive material to produce robust plasterer friendly beads. Renderplas PVCu beads conform to BS EN 13914-1:2016 – External Rendering.

Renderplas products are designed to be unobtrusive with an extremely narrow arris, making it ideal for scratched or scraped finishes. Very popular with major house builders, its beads are available in white or ivory as standard to blend with most coloured renders. However, in order to give architects and contractors even more freedom to use through-coloured renders in more vibrant colours, a range of beads in 7 further colours are also available for popular render depths.

Used internally, whether, in conjunction with wet plastering or dry lining, they will not stain during lengthy drying out periods and offer superior protection against impact in heavy traffic areas.

By specifying a Renderplas PVCu bead, the problems associated with traditional beads and the aggravation of costly callbacks are avoided. Two different CAD file formats are available for Renderplas profiles from the Downloads page of its web site.
