Our stainless steel, perimeter retention Tension Springs are an accessory required when installing Fixed Head and/or Self Levelling Pedestals.
One Tension Spring is placed onto each pedestal running along a perimeter wall or upstand, and an additional one on each corner pedestal.
The Tension Springs’ curved exterior spring plate enables paving tiles to be locked in position. This helps to avoid direct contact between the paving tile and the perimeter wall, and also helps to prevent paving creep over time.
For more information on how to install Tension Spring for raised porcelain paving, please see section 2 or our Raised Paving Installation Guide.
