Concrete Expansion Joint System

The new A.S Expansion system offers numerous benefits over existing expansion systems.

Permanent Shutter - NO stripping shutter.

Precision Height set up - Adjustable to be millimetre perfect.

Precision Dowel Bar set up - Adjustable to precise levels.

Set up by Steel Fixers - on site training or fitting available if required.

Joint Seal is Part of the Expansion - no going back to site to strip and seal joints.

No chipping the concrete edge.

Suitable for power screeds to run on.

Dowel Bars can be removed from the side of the Expansion which is not been poured to avoid trip Hazards - or a Continuous pour beyond the Expansion system is now possible. Steel fixing and pouring an entire area gives excellent economic advantages in particular for companies who use subcontractors or those working to a tight programme.


Acra Screed Concrete Expansion Joint System

With the AS Expansion you get the full package from the permanent shutter and expansion foam right down to the tie bars, dowel bars, dowel caps and the expansion seal itself. The shutter section comes pre fitted with the expansion foam and stud connectors ready to take the dowel bars. The dowel bar cradle which is only fixed on the first side of the expansion is also part of the package.

The system has been designed by many years of onsite experience and a thorough understanding of on-site demands. You can prepare all the steel work in the slab and have the expansion in place ready for the concrete crew who can then carry out a continuous pour. You don't have to go back to site or wait for a dry day to fill the joint the benefits are multiple.

Better Quality - not only is the system better for you, its a much better finish for your customer because the seal is locked into the concrete and its innovative design allows movement in the joint.

For the seal itself we have teamed with NUFOX Rubber - Formed in 1981, the Manchester based company are at the forefront of their sector, through various acquisitions their in house experience dates back as far as 1933 making them true experts in the field.

Nufox presently serve – among others, the Construction, Aerospace, Defence, Marine, Rail and Oil & Gas sectors.

Debbie Garside – Sales Nufox Rubber

When Acra Screed approached us to manufacture their new expansion joint seal our team took careful consideration as to its application. Nufox recommended EPDM, because it has good weathering properties. Its resistance to UV and its durability in freezing temperatures makes this material the best choice when exposed to the elements.

This material is used for general industrial / commercial applications including: seals, Boat fenders, glazing sections, cable protectors, weighbridge rubber, wall guards and other high exposure miscellaneous sections. Excellent water/steam, weather properties; and good chemical resistance, although not advised for mineral oils, in which case we can provide a Neoprene or Nitrile seal.

The Expansion video below gives a workshop demonstration of the new A.S Expansion system been set up and gives a good overview as to how the system works.
