Expansion Foam Roll 200mm Fosroc Expandafoam Joint Strip.
The fast, efficient, cost effective system for all brick and concrete expansion joints.
Typical applications include:
- Expansion joints in floor slabs
- Expansion joints in brickwork
- Bon breakers between pre-cast panels
- Frost blankets
- Grout checks
- Stop edges
- Back-up / bond breaker strip to support sealants
- Bridge decks, abutments, pier hinge joints
- Brick and blockwork in building superstructures
Benefits and advantages:
- Light and easy to handle
- Can be used under any weather conditions
- Ready to use and needs no preparation time
- Achieves accurate depth of sealant
- Eliminates damage to concrete edges
- Saves time and saves money
- Readily compressible
- Low load transfer
- Excellent recovery after compression
- Non-absorbent
- Rot-proof
- CFC-free
This comes ready to use and does not require any preparation just put it in place.
The top edge is pre cut for stripping saving time and money over more traditional methods.
It forms the most accurate expansion joints possible and does not absorb water so will not deteriorate in bad weather.
It forms an even depth recess for the sealant eliminating edge damage.
Simply pull out the top strip to achieve a perfect joint every time.
Application instructions - Joint sealing slots
When used as an expansion or isolation joint filler in brickwork, Expandafoam should be positioned to provide for a surface sealing slot of the required dimensions ensuring that the sealing slot is free from mortar droppings or slurry bridging.
Expandafoam sheets may be fixed into position using a suitable adhesive.
Care should be taken not to contaminate the surfaces of the sealing slot with adhesive.
Where Expandafoam is used as the joint filler no additional bond breaker is necessary.
Used as a backup / bond breaker strip Expandafoam serves both to regulate the depth of the sealing slot required and ensures that the movement of the joint sealant is not restricted by three-sided adhesion.
The size of the backup strip should be approximately 20% greater than the joint width and depressed sufficiently to provide the required sealing slot dimensions.
Circular cord sections provide a convex face giving an optimum seal configuration, they also overcome any problem of twisting which can occur with square or rectangular sections.
