Micro Piling
Used for the
installation of foundations where access is limited
- New foundations for Housing (Up to 3 plots
at any one time) close to sensitive areas.
- Factory units for Mezzanine floors.
- The installation of foundations within
factory units for heavy machinery where the settlement criteria
is critical.
- For the construction
of retaining walls, and retro-fit basements.
Used within restricted areas for poor ground conditions, where
deep foundations are impracticable. For extensions to homes and one off
housing plots we offer a full design service including site
investigation to meet NHBC and Building Control standards. We also
design and construct foundations for machine bases, and mezzanine floors
where access is limited.
Used within restricted areas for poor ground conditions where deep
foundations are impracticable. Extensions to homes, one off housing
plots machine bases and mezzanine floors for example primarily used as
an alternative to bottom driven piles to offer a higher load capacity.
Used in ground conditions where heave may be a possibility, but the
ground conditions will allow the pile bore to stay open. A plastic
coated liner can be installed to a designed depth to minimise heave.
Temporary casings can be used to support ground that may be unstable
towards the top of the pile. This means the pile can still be filled
with concrete from the top as the casings are removed.
Used in ground conditions where heave may be a possibility, but
the ground conditions do not allow the pile bore to stay open. Heave
conditions will be designed out by increasing the depth of the pile and
the reinforcement used. This pile is filled with concrete through the
centre of the augers as they are retracted.
There are several methods used for this type of drilling. These are used
where the ground conditions do not allow a driven or an augered pile to
be used, for example a quarry that has been backfilled in an
uncontrolled manner.
A permanent casing is drilled through the fill ground onto the rock
head, dependent on the system used, the drill will then continue on into
the rock to form the pile at the designed length, or the overburden
drill is removed and another type of drill is used to complete the
drilling into the rock head. The pile is then filled with a designed
grout mix from the bottom.
Used for drilling into un-reinforced concrete and rock. Can also be used
when the overburden drilling has reached the rock head.
This can be used in most ground conditions and is probably our
most versatile pile. The drill bit and bar is sacrificial and are
drilled to a designed length and filled with grout through the centre of
the bar and drill head.
This pile requires a great deal of torque so uses our larger mini rigs.
It is installed in a similar way to a Sectional Flight Augered pile to a
designed length. However there are no pile arisings to remove and in
certain ground conditions higher loads are achievable due to the nature
of the installation.
Used primarily with an augered pile to form a retaining wall
for example underground car parks. The piles are installed approximately
50mm -100mm apart dependent on ground conditions.
Used primarily with an augered pile to form a retaining wall the pile
spacings are dependent to position. The piles are formed and an I
section structural steel beam is lowered down into the pile bore
vertically and then concreted into position. Designed concrete
planks, or similar, are then placed between the webbing of each I
section beam to form a retaining wall.
