about us

The X-Tend-A-Wall™ extension sleeve was invented in 1995 and revolutionised the way in which pre-cast walls could be extended in height. There have been many methods and products used before the advent of X-Tend-A-Wall™ extension sleeves. These methods were effective in extending the height of a pre-cast wall, but looked unsightly and the processes involved were far from cost effective.

The conventional way of extending a pre-cast wall is called the pole on pole method. This method of extending a pre-cast wall is fundamentally flawed and severely impairs the structural integrity of the extended structures.

The standard dimensions of concrete pillars that are manufactured by the vast majority of pre cast concrete walling manufacturers are usually 130mm x 130mm by the height. These dimensions may however vary depending on the condition of the moulds used to cast the pillars. Over the years, different manufacturers have used varying dimensions of moulds for manufacturing pillars and slabs.

The fact that there are many different sized poles, often cast in poor conditioned moulds, makes it difficult to extend a pre-cast wall in the most effective way possible with the pole on pole method. If an existing pillar measures 140mm x 135mm, it wouldn't make structural sense to put a concrete extension post that measures 130mm x 130mm between the angle iron that is separate by the dimensions of your existing post. The steel used to support the extension pillars are very rarely treated with an anti-rusting agent causing sever problems over the medium to long term and could present a very serious safety hazard.

This is, however, not the case when using the X-Tend-A-Wall™ extension sleeve. The extension sleeve is made of a high strength, galvanised steel that can be manufactured, on demand, to fit any size pillar with any dimension. The X-Tend-A-Wall™ extension sleeve can extend the height of a pre-cast wall by 1.8 meters, whereas with the pole on pole method, the maximum extension height is 0.6 meters before the extended structure starts becoming flimsy and dangerous.
