Felix Group Qatar - Floor Screeding

Protection of the building structure

Core drillings don’t leave any subsequent damage on

sensitive parts of the basic structure of a building

since they operate vibration-free.

Environmentally friendly and clean

With core drilling, concrete compounds can be

broken down into any desired size. Therefore they

can be easily disposed of and dumps or waste

disposal sites are no longer needed. Further, core

drilling uses water cooling and is relatively fast

executed, noise pollution and dust formation are

reduced to a minimum.

Ready anytime and anywhere

In particular, the wire saw is among the diamond

cutting techniques for hard to reach objects, intricate

cuts and in sensitive environments. Even core drilling

or sawing under water are no problem.

Equipment

We use our own fleet of screed pumps to site mix the screed. With our years of experience we

have the knowledge to know the exact quantity of materials to use. Using our screed pumps to

site mix the screed gives greater flexibility, ensuring that we have control over standards of

materials used and is more economical. We can install screeds up to 2500m² per day.

Most Common Types of Screed

More about screed

A Screed or sometimes called Screeding

is simply a type of concrete used to form

a level surface either to receive floor

finishes (such as floor tiles or carpeting),

to encase underfloor heating pipes or to

be left as the wearing surface. It is laid

either on top of the excisting concrete

base, a damp proof membrane (DPM) or

insulation.

Screeding is the process of cutting off

excess wet concrete to bring the top

surface of a slab to the proper grade and

smoothness.

Traditional Screed / Sand Screed

Traditional Screed is also known as Sand

cement screed and is used for many

applications. They are designed to provide a

smooth, flat, level surface, suitable to receive

the floor coverings.

Sand cement screed can be batched on site

using modern screed pumps.

Liquid Screed / Flow Screed

Liquid screed, also known as flow screed is a

screed in liquid form and can be pumped onto

both ground and upper floors.

The benefits of liquid screed are enormous.

Large spaces can be covered in a short period

of time, reducing man hours. Shallower floor

depths can be achieved and set to laser

accuracy. Liquid screed can be bonded and

un-bonded, like traditional screeds.

Screed mixing

The screed mix generally consists of sharp sand, cement

and water and standard ration is a 1:4 mix design. It needs to

be mixed using a forced action that is provided by a screed

pump which ensure that it is accurately batched and fresh.

Pumps also transport the mix to the working area.

Process

We survey the space with a laser level, take measurements

from the datum and transferring this across the space. We

also ensure that this level is applied to the middle of the floor

and the perimeters.

When laying the mix, we manually compact it to expel any air,

which helps prevents voids or hollows and further

strengthens it. This is also not a common practice in the

industry but as we take such pride in the quality of our work, it

is a method that we train our screeders to do.

Our screed is laid to the highest standard of surface

regularity. This means a spot on surface for your floor

finishes which is the whole point of having a screed laid.
