Expansion joints in concrete are an important feature which counter effects the impact of concrete contacting or expanding which may in turn lead to cracking of the slab and thus structural weakness.

The Connolly expansion joint is a roll-formed galvanised steel section with 10mm cross linked foam that facilitates joint expansion without negative consequences. The patented twist and fix feature allows dowels to be aligned to offer unhindered slab movement and the straight profile ensures that load is transferred through the dowels only. Other invaluable features of the Connolly expansion joint system include the galvanised coating which limits corrosion plus additional stiffening which helps you to achieve straighter joints. Furthermore, this joint enables continuous pour and can be used to screed off, making getting the right level fast and easy.

In general terms, you are going to use expansion joints wherever a slab of concrete is going to come into contact with another surface – even if that other surface is more concrete. Expansion joints are a fundamental part of large concrete structures that prevent damage resulting form the slight expansion and shrinking of concrete as it is subjected to external influences such as changing temperatures.

One of the most popular ways of creating efficient expansion joints when creating slab on the ground concrete jointing is by using the Connolly Expansion Joint System, a simple to use but ingenious device that has been developed to cope with slabs of differing heights and thicknesses. With each of the joints that you purchase you receive the galvanized steel section, an appropriate number of bars and sleeves plus wedges and pegs which are used to effortlessly make accurate height adjustments. Further advantages of the Connolly system are that it enables continuous pours (saving time) and facilitates up to 10mm expansion. With in excess of 30 years in the market, the name Connolly is now synonymous with quality in the arena of concrete joints and is widely used for a wide range of applications.
