Description:

Low capacity bearing slips made from dense extruded polyethylene sheet for fixed end rotation joints or as a low friction, structural slip membrane

Uses:

• Slipstrip™ 2 is an economical low capacity, low friction bearing strip which can be used under in-situ or precast concrete slabs and beams, structural steelwork bearing plates and pipe supports to form a thin sliding joint. It is extruded from specially formulated polyethylene to form a durable laminate which is resistant to most chemicals, solvents and weathering.
• Slipstrip 2 is therefore ideal as a permanent bearing strip in all conditions of exposure subject to the loading conditions. The bearing strips are formed by layering two sheets together, smooth to smooth face, with drafting tape or similar to prevent the ingress of fines and concrete grout between the sliding faces.
• The textured bottom layer is then bonded on to a smooth true bearing substrate with Pak Adhesive. Concrete is then cast onto the top layer. Two layers of Slipstrip 2 can also be used for sliding wall joints, pre-stressed, posttensioned circular concrete tanks or similar structures provided the safe load bearing capacity is not exceeded.

Advantages:

• Economic – easily installed on flat surfaces without affecting bearing height
• Thin section – allows use in restricted areas; does not effect concrete cover
• Low coefficient of friction – prevents drag and spalling at extreme edges
• Deformable – accepts minor irregularities in concrete surfaces, prevents locking-up of bearing
• Positive separation – creates slip-plane between dissimilar building materials
• Slipstrip 2 – for sliding joints having a max load – 0.7 N/mm2 with coefficient of friction – 0.15
