DIAMONDS
Diamond tools have been used in construction
for many years. However it is only in recent years that
the versatility that diamond tools offer have been used
to their full extent. A saying we have in ECR International
is that the limit is our imagination, not our tools.
The diamonds used were originally all natural diamonds.
Now they are almost all synthetic. This is generally
because quality, size and shape are controlled so therefore
there is more consistency in performance of an individual
tool.
Diamond tools are used for three main functions; wire,
saw blades and drill bits. |

WIRESAWS
There are two elements to a wire
saw. The first element is the machine that drives the
second, diamond wire. Diamond wire consists of a 6mm.
diameter steel core, to which beads are threaded over.
These beads are held in position by either springs,
injection moulding or both. The beads have small chips
of diamond spread throughout. The beads when new are
11mm in diameter and wear down to about 9mm. in diameter.
The wire is threaded around or through the concrete
that needs to be cut. There are many different possible
setups; suffice to say that a wire saw is very versatile,
and there are very few jobs and/or material that it
will not handle.
Wire saws are quiet. Therefore they are ideal in noise
critical areas such as hotels, hospitals and occupied
buildings.
There are too many variables of wire sawing to describe
in a brief description here. If you have a problem with
concrete removal call us. |

These are more common than wire saws.
Within this category of concrete cutting machines are
three sub-sets.
-
Floor saw. Most
common of concrete cutting machines. Range in power
from 8hp to 80hp. Will cut concrete up to 600mm.
thick. Floor saws are mostly petrol or diesel powered.
In confined spaces ECR International uses 3-phase
machines.
-
Wall saw. Can
cut up to 800mm. deep (from one side). However,
generally if we have to cut a wall greater than
500mm. thick we prefer to use a wire saw. The decision
on which machine to use depends on the individual
project that is being undertaken.
-
Hand saw. Are
very versatile. However they are limited to cutting
to only 250mm. They are either petrol powered or
hydraulic.

DRILLS
In most commercial and industrial buildings there are
a large number of holes that allow services to go from
floor to floor or room to room on the same floor. There
are a large number of sizes and depths. ECR International
conventionally drills holes up to 750mm. in diameter.
Depending on diameter, the company can drill to a depth
of ?. Our limit has not been reached yet. On seismic
upgrade work we drill to 15-20 metres deep and 76mm.
diameter. For holes over 750mm. diameter, we use an
attachment to our wire saw that will "drill" a hole
to almost any diameter.
There are a number of options for removing concrete.

your concrete problem.
