Concrete floor screed

concrete floor 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.

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

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 Process

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.
