Needle Support Systems

What is Needle Support Systems?

The “textbook” method for supporting a wall is to punch holes in the wall every 90 to 120cm and insert needle beams through the wall. The ends of the needles are propped, leaving a working space beneath for inserting the lintel. This is reliable and robust, however the common objection to this method is the disruption to the rooms above and the need to repair the holes afterwards.

Generally needles are used to transfer the load from above to the hard standing below and the needles can vary on strength and width a part to suit the loads however when there is not a suitable footing or hardstanding to transfer the load through then an alternative needling system can be used known as “Balance propping” which transfer the loads from the top of the wall to the base.

‘Stool’ lost propping systems – This method can be used where the existing foundations are in a poor condition and it enables the wall to be underpinned in a continuous run without the need for needles or shoring. The reinforced concrete beam formed by this method may well be adequate to spread the load of the existing wall or it may be used in conjunction with other forms of underpinning such as traditional and jack pile.
