The newly patented expansion system from Acra Screed is pioneering innovative thinking for concrete joints, saving contractors money and time and providing a superior end product customers will love.

The Acra Screed Expansion Joint forms an Integral part of the concrete slab. The thin galvanised steel shutter comes complete with expansion foam. Utilising the Base Block units and adjustable height support, the expansion is quickly levelled to the precise height required and plumbed up using bars that link into the shutter and are steel-fixed to a plumb position. The EPDM Rubber cap slides securely in place and can be used as a screed-off point when pouring, but, more importantly, it becomes the finished joint product.

With no shutter to strip, you no longer have to stop the pour at the expansion joint, saving money on concrete pumps and part loads and leading to greater productivity overall. No more going back to cut the joint or stripping back the expansion Foam, waiting for a dry day to polysulphide joints. The joint is already in place and secured into the slab, with integral voids and branches linking to either side of the concrete joint. It has been designed explicitly for contraction and expansion.


Alongside the basic package, which includes the Shutter, Expansion foam, Base blocks, Adjustable height Brackets, and Tie bars, Acra Screed also offers a stop-end option using threaded Dowel Bars and Stud Connectors so that a slab can end without leaving Dowel Bars stuck out of the slab, a trip hazard most Concrete contractors will be well aware of.

The system keeps things simple, and for contractors, it saves time and money for all the reasons mentioned above. For the customer, it leaves a better joint system that will far outlive the polysulphide joints presently used.

Manufactured in the UK, the expansion joint can be quickly modified to suit on-site requirements, including Dowel Bar size and spacing variations and Concrete depths. Like the original Acra Screed Rail system, the new Acra Screed concrete joint was developed by a civil engineering contractor with 50 years of on-site experience placing large volumes of concrete.
