Resistance piers are used for supporting structures.
Typically they are used to underpin failing structures.
They can be installed from either inside or outside of the
building. How the work. Resistance piers are steel piers
that have an L-shaped bracket that attaches to the underside of
an existing wall. The pier uses the wall as resistance to
push a steel pipe into the ground. Pipe is driven until 1)
a required load is achieved (which can be easily determined by
identifying the PSF used to drive the pipe), 2) required depth
is achieved, or 3) the structure begins to lift.
The steel pier can be left hollow or filled with grout to
minimize corrosion. |
