Piling used to support
existing defective foundations or individual
structures in difficult working conditions
or unsuitable ground conditions.
This work would normally incorporate
reinforced concrete beams or pads placed
underneath the existing foundation or placed
to receive the structure and supported
each end or where required by small diameter
piles.
Reinforced concrete
slabs placed at ground floor level designed
to support the loading
of buildings or structures. They can rest
directly on the ground or can be supported
by piles if required.
Needle rafts more normally used in existing
buildings have projections on the edge
of the slab “needles” which penetrate the
existing structure to provide support.
Traditionally this
would encompass mass concrete fill under the
foundation of an
existing building or structure to distribute
the loading across a greater area or onto a
stronger strata.
Alternatively needle beams under the
existing foundation supported by mini piles
could be utilised.
Reinforced concrete or
composite walls designed to withstand the
horizontal loading
of unequal ground levels where the height
difference is such that the soil will not
support itself.
Permeation grouting is
the direct injection of a fluid grout into
the ground to fill the voids between
particles and improve the load bearing
capability of the ground.
Injection methods are tailored specifically
to a project and the choice of materials
offer hundreds of options ranging from
cement slurries to chemical solutions.
Some or all of the
above could be used in basements, lift pits,
sewage treatment plants etc. constructed to
the designs of others to a high degree of
precision.
Our design and calculation service is also
available to problem solve, design and
provide the documentation required to prove
the suitability of the proposed work.
