The application of SpECcell Polyethylene 60 is essential for forming and filling expansion joints in various construction settings:
In Concrete:
SpECcell Polyethylene 60 can be placed against formwork on the concreting side prior to placing the first section of concrete. It remains in place after the removal of the formwork, allowing for the subsequent pour to be cast directly against it. The board can then be cut back later to form the sealing slot.
In Blockwork and Brick:
When laying brick or blockwork, SpECcell Polyethylene 60 should be installed to create a sealing slot of the required dimensions. This ensures proper function and performance of the joint filler within the structure.
SpECcell Polyethylene 60 is available in various sizes to meet project requirements:
- Thickness: 10mm, 15mm, 20mm, 25mm & 50mm
- Board size: 1m x 2m
