SpECcell Polyethylene 40


SpECcell Polyethylene 40 is a high performance
closed cell polyethylene foam joint filler. It is
suitable for use as an expansion joint filler in
concrete, brickwork and blockwork, and in isolation
joints where a readily compressible low load transfer
joint filler is required.

Meets the require ments of BS 5628 Part 3 

SpECcell Polyethylene 40 is a compressible joint filler in sheet form, used to form and fill expansion joints.

In Concrete:
SpECcell Polyethylene 40 can be placed against formwork on the concreting side prior to placing the first section of concrete and is left in place on removal of the formwork. The subsequent pour is then cast directly against the SpECcell Polyethy lene 40. The board is then cut back later to form the sealing slot.

In Blockwork and Brickwork:
SpECcell Polyethylene 40 should be installed, whilst laying brick or blockwork, in such a way that a sealing slot, of the required dimensions is formed.
SpECcell Polyethylene 40 is available in the following sizes:
. Thickness: 10, 15, 20 & 25 mm
. Board size: 1m x 2 m
