`Pynford' Stool Method of Underpinning ~ 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.
