Cantilever Needle Beam

In underpinning. A cast in situ concrete beam, usually sat on piles or concrete piers that passes through and supports a wall, or foundation from one side of the wall only.

Tension Pile

In foundations work. A pile that works in tension. For example one at the tail end of a cantilever beam.

Note! The above sketch is an indication only and the piers would be deeper and the rebar is a brief indication only.

This type of beam has the advantage of being a lot less invasive to the property than the standard needle beam. The underpinning work can be done entirely from the outside of the property.

All for ourselves, and nothing for other people, seems, in every age of the world, to have been the vile maxim of the masters of mankind." Adam Smith 1723-1790
