DIAMOND CONCRETE CUTTING (REINFORCED CONCRETE)

Diamond concrete cutting means cutting concrete by using rotating tools with attached diamond segments.

Diamond concrete cutting can be divided into three groups: (we perform all three)

  1. Cutting of floors, sheets and other horizontal elements
  2. Cutting of walls, pillars and other vertical elements
  3. Cutting with diamond cables 

The machines can also be divided into:

  1. Floor cutters
  2. Wall saws
  3. Diamond cable machinery

FLOOR CUTTERS
Floor cutters can be run by electro-motors (mostly used indoors) or petrol/diesel motors. They are usually used for cutting sheets or making floor troughs. The cutting depths is usually no more than 50 cm, and the motor power is 5-180kw.

WALL SAWS
Wall saws are powered by electro-motors or hydraulics and their main feature is that the moving parts of the machine are installed onto drivers which are affixed to the wall. In some cases they are also used for floor cutting (when precision is needed or when there's not enough space for floor cutters). Cutting depths are no more than 90 cm, motor power usually 5 to 30kw.


DIAMOND CABLE MACHINERY
These machines run cables sheathed with diamond rollers (like pearls) and simultaneously tighten them into a small rotating loop belted around the element which is being cut. The thickness of the elements being cut isn't limited, and they're often used in cases where access by other machines isn't possible. The power is usually 15-30kw, run by electricity or hydraulics.

We use all kinds of machines in our operations, along with all adequate equipment such as scaffolding, props, electropneumatic hammers, generators, mobile reservoirs...

All electric-powered machines demand 380V electricity stronger than 16 A and all cutting is executed with water-cooling of the cutting tool. The objects are protected from water damage by absorbing and diverting the water.

If we needed, we dispose of cut concrete slabs on our own dump.

 

DIAMOND CONCRETE CUTTING (REINFORCED CONCRETE)

Diamond concrete cutting is performed with electric or (seldom) hydraulic drills consisting of a pedestal with a driver, sliding part which moves along the driver, motor and a diamond drill bit. The pedestal is firmly affixed to the element that's being drilled and the part to which the motor is attached slides along and rotates the drill bit. The drill bit penetrates the element and simultaneously gets water-cooled. The usual drilling diameter is 8mm to 500mm, and larger diameters are also possible with the use of special techniques.

We use a number of drills with different characteristics and are fully capable to protect the objects from the outpouring of technological water.

The drills mostly use 220V electricity and are plugged into standard power sockets.
Drilling depths can reach a few meters.
We're capable of performing all standard and non-standard kinds of ferroconcrete drilling. 

DEMOLITION OF MASSIVE CONCRETE BY HYDRAULIC PISTONS
In cases where diamond concrete cutting isn't possible, there is a possibility to demolish concrete elements by installing hydraulic pistons in pre-cut slots. The pistons (under 200 bar pressure) expand and create a 400T /piston pressure i. e. 800T with one pair of pistons and cause the concrete elements to break. 

COMBINED METHODS OF REINFORCED CONCRETE DEMOLITION

In certain cases there is a need for combining all aforementioned techniques and the involvement of the subcontractors' equipment and engineering. This mostly means cranes, machinery with hydraulic hammers, forklifts, construction machinery and trucks/flatbed trailers to transport the cut concrete. To avoid possible damage, some parts of structures can be detached by diamond techniques and then completely removed by construction machinery.
