SLIPSTRIP™ 2
Low capacity bearing slips made from dense extruded polyethylene sheet for fixed end rotation joints or as a low friction, structural slip membrane
Product Applications
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.
| Performance | |
|---|---|
| Slipstrip 2 | |
| Maximum load | 0.7 N/mm2 |
| Coefficient of static friction | 0.15 |
| Operating Temperature | -29⁰C to 50⁰C |
Installation
Do not bond into position when temperature is below +5°C.
The bearing substrates should have a steel float finish and be true, smooth, dry, free from dust and debris before bonding the two layers of Slipstrip 2 on to the surface.
Slipstrip 2 of the appropriate width must be formed into an enclosed envelope to prevent the ingress of fines and concrete grout by sealing the edges and all staggered joints with masking tape or similar prior to installation and pouring of concrete. The smooth faces must be married together with the textured faces on the outside.
Joints between layers should be staggered wherever possible and circular fabrications should be formed in short chord lengths with staggered joints.
Pak Adhesive should be applied by brush in a full bodied coat on to the bearing surface and to the textured face of Slipstrip 2. When touch dry the Slipstrip 2 should be offered carefully into position and well rolled to achieve full contact bonding. For full instruction on the use of Pak Adhesive refer to the application guide on the can.
Typical Rotation/Sliding Joint
All test results shown in this data sheet are determined under laboratory conditions and with the product sample taken directly from stock in its original packing without any alteration or modification of its component parts.
Product 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
