MARKCHEM POLYETHYLENE 100
DESCRIPTION
MARKCHEM POLYETHYLENE 100 is a semi-rigid, U.V. resistant, high performance closed cell polyethylene foam joint filler in sheet form. It is suitable for use as an expansion joint filler in concrete, brick, blockwork and isolation joints, where a readily compressible low load transfer joint filler is required. It is non-tainting and therefore suitable for use in potable water retaining and water excluding structures.
APPLICATIONS
- Structural expansion joints in concrete, brick and blockwork
- Isolation joints to infill panels
- Bridge joints, abutments, pier hinge joints
- As a back-up support for sealants.
- As a bond breaker for sealants over bituminous joint fillers
- Anti-vibration pads for machinery bases
ADVANTAGES
- Completely fills the joints under repeated cycles of expansion and contraction
- Resistant to moisture penetration and ice formation in the joint
- Will not support dry or wet rot, fungus attack or similar forms of deteriorating agents
- Non Taint
- Cross-laminated to resist lateral and hydrostatic pressure
- Natural bond breaker
- Low load transfer to joint edges under compression
STANDARD COMPILES
- BS 5628 Part 3 : 2001
- U.K. Department of the Environment General Specification 201, Clause 606

COMPRESSION LOADING
Meets the requirements of BS 5628 Part 3. At the very low rate of compression associated with the moisture expansion of fired clay brickwork, the compression loads will satisfy the advisory about 0.18N/mm2 in the B.S. 5628 Code of Practice.
Polyethylene 100 meets or exceeds the
requirements of the following specifications:
U.K. Department of Transport Specification for Highway Works Part 3 – Clause 1015. 1991
APPLICATION
Polyethylene 100 is a compressible joint filler in sheet form, used to form and fill expansion joints.
In concrete – Polyethylene 100 can be placedagainst 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 thePolyethylene 100. The fibre board is then cut back later to form the sealing slot.
In blockwork and brick – Polyethylene 100should be installed, whilst laying brick or blockwork, in such a way that a sealing slot, of the required dimensions is formed
