Principality Stadium, Cardiff
Commercial and Industrial floor screed by Saint-Gobain Weber was specified for the regeneration of an existing open basement to a new plant at the Principality Stadium in Cardiff.
Originally known as the Millennium Stadium, when the Principality Stadium in Cardiff opened in 1999, it was the first venue in the UK with a fully-retractable roof. Twenty years on, the national stadium of Wales welcomes an average of 1.3 million visitors every year. It is well known to rugby fans as the home of the Wales national rugby team, hosting some of the biggest events in the sport, including matches from the Rugby World Cup and the RBS Six Nations.
As part of an extensive site-wide maintenance and upgrade project, 220m2 of open basement floor area needed to be levelled, finished and ready to withstand foot traffic within a short timescale of just three days. Industrial and Commercial flooring specialists TPS360 were appointed to complete the subfloor.
The open basement area needed to be repurposed to become a plant room. As it was previously open to the elements, it had required drainage, so the inclined subfloor needed to be made level by an average of 18mm ready for the installation of a pump and a generator. The lowest point of the original subfloor required 27mm of screed, and at the highest point only 5mm.
The flooring elements of the project were run by TPS360, an industrial and commercial flooring provider and installer tasked with completing the new subfloor within a three-day window.
“It was important that we used products that would maximise the time we had available to us,” said Tim Bratcher, operations director at TPS360. “With such a tight time scale, everything needed to run on time. We’d worked with Weber on other smaller projects, so knew they would be able to help us to pick the best combination of products so that everything ran smoothly.”
To prepare the existing floor for the screed, TPS360 used weberfloor 4716 primer. The team then applied weberfloor fibre 4310 self-smoothing base and renovation screed to 220m2 of floor space within three hours. weberfloor fibre 4310 can be applied to depths of 5-50mm and can receive foot traffic after just 2 - 4 hours and can be tiled after 12 hours, dependent on ambient temperature following installation. The fibre reinforcement aids durability and allows it to be used in conjunction with under floor heating systems and floating floors.
Another layer of weberfloor 4716 primer was then added and, once dry, weberfloor industry rapid 4655, a hardwearing topping screed, was applied. weberfloor industry rapid 4655 is a rapid drying, self-smoothing industry screed and resin receiver which can be applied to depths of 4-15mm. Suitable for use in industrial areas, light foot traffic is possible after 1-2 hours in normal conditions and final floor coverings can be applied after 24 hours depending on layer thickness and drying conditions.
The subfloor was completed within the required timeframe allowing the rest of the works to continue as planned. TPS360 finished the floor with a hardwearing epoxy resin coating.
Tim Bratcher at TPS360 commented “We were really pleased with the speed at which we could apply the screed and that after each layer we only had to wait a matter of hours rather than days before we could make any progress. It meant that we could do our part and clear out ready for the other trades that needed to come in as soon as possible. Jobs that run to time are every contractors dream, so we’d definitely use Weber again for a project like this.”
As this was the first major commercial project that TPS360 had specified Weber products for, Phillip Powell, application manager, and Ian Brookes, specification sales manager, from Saint-Gobain Weber came to the stadium to provide technical support to the team on site.
Phillip Powell, application manager at Saint-Gobain Weber, said: "Anyone that comes to the Weber Technical Academy gets application support on their next flooring project. We come to site to help them set up machines, check they have the right water to material ratio and help them to check the product consistency, just to get them started and make sure they’re happy with the system they’re using."
“The Principality Stadium is one of the first projects to have used our flooring screeds since they have included Low Dust Technology™. Everyone on site noticed the difference and less dust meant less cleaning up after the initial installation, which helped the project to move even faster."
Weber products are manufactured in facilities in Bedfordshire, Shropshire and Co. Antrim ensuring that they are produced close to the markets they serve. This results in reduced transportation costs and carbon footprint when compared with the importation of products and materials, as well as the fact that Weber’s customers benefit from improved availability and competitive prices.
