Applications of SpECcell Fibre 35
Expansion Joint Filler:
SpECcell Fibre 35 is a compressible joint filler in sheet form, specifically designed to form and fill expansion, isolation, and control joints in various construction applications. Concrete Applications:
In concrete construction, SpECcell Fibre 35 can be placed against formwork on the concreting side prior to placing the first section of concrete. It remains in place upon removal of the formwork, facilitating a direct cast against the fibreboard. Later, it can be cut back to create the necessary sealing slot. Brick and Blockwork:
When used in brick and blockwork construction, SpECcell Fibre 35 should be installed such that a sealing slot of the required dimensions is formed during the laying process. Protection Course:
As a protection course, SpECcell Fibre 35 is utilized to provide a continuous protective layer over waterproof membranes, ensuring durability and performance in harsh environmental conditions. It can be bonded to the membrane using a rubberized bitumen mastic or other suitable adhesives. Versatility:
The product is versatile and suitable for various applications including, but not limited to, joints in trafficked surfaces, bridges, roads, runways, pedestrian areas, as well as temporary fillers in expansion joints and structural separation joints between buildings.

SpECcell Fibre 35 is available in a range of sizes to meet diverse project needs:
Thickness: 10 mm, 12.5 mm, 19 mm & 25 mm
Board Size: 1220 mm x 2200 mm
