They will assess the project and determine the appropriate sort of screed you need and the best strategy for applying it.
They will in addition assess if a structural engineer is required to make sure any flex strength, point loadings and load requirements are followed as set out in building and construction regulations.
The training and skills that a qualified screeding technician brings to your project should guarantee a successful result and help to extend the lifetime of your floors. Choosing the correct screeding materials and the best installation technique is vital if you want to finish up with a quality and durable finish for your floor surface.

The price quote could be based on what's called the Surface Regularity, or SR number. Each of the 3 SR levels offer different standards of finish, with SR1 being the best, with the lowest amount of deviation over the surface area. This could mean that you might have to fix any areas that may cause problems when putting down your finished flooring solution.
Every Westminster screeding company has to comply with British Standards (BS8204) and ought to have accreditation from the manufacturers of screeding materials and equipment, e.g. Gypsol, Flowcrete, Cemfloor. The training and testing of a screeding contractor by a manufacturer is underlined through the accreditation scheme, and guarantees safe working practices and reliability on any flooring project involving their materials.
For larger screeding projects in hospitals, schools, restaurants, factories, shopping centres and warehouses, dedicated Westminster commercial screeders will be needed.
TYPES OF SCREED
Standard Screeds - A blend of cement and sand which is perfect for basic domestic use. This mixture comprises a five to one ratio of sand to cement. Once it has been laid this 5:1 ratio dries at a rate of one millimetre each day.
Fibre Reinforced Screed - The preferred option for professionals where under floor heating is being installed in residential properties in Westminster. The improved flexibility and strength offered by the fibres within this screed help protect the flooring from thermal cracking and shrinkage. It dries at the same rate as a standard screed of 1mm per day.
Fast Drying and Advanced Drying Screeds - As the name suggest, these screeds dry at a quicker rate and allow you to use the floor area much faster. The vast majority of the fast or advanced drying screeds are fibre reinforced and are appropriate for a wide range of flooring projects where the swifter drying rate of 3-7mm is an advantage.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading on the floor is needed, heavy duty screeds provide maximum durability and strength.
Polymer Screeds - These provide an extremely high level of strength with a reduced thickness. Manufacturer's guidelines for curing times vary across the product ranges.
Self-Levelling or Liquid Screeds - Used to provide the highest quality of finish, especially in SR1 levels of screeding, by a latex and cement mixture. It is largely used to provide a smooth, clean floor over the top of a poor quality or damaged substrate and enables all types of flooring materials to be used. Even with a thickness of just one millimetre, the latex polymers within the mixture provide a high strength screed for a wide variety of uses.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a good quality finish that is durable and hard wearing, time should be devoted to carefully preparing the area before any screed is laid. It's vital that any contaminants such as oil, paint, grease or loose debris is eradicated from the floor surface before laying any screed, because these can affect the adhesion capability that a quality screed needs.
If any cleaning products were used in this process it is crucial to make certain that no residues of soaps or other cleaning products are left on the surface and it is permitted to dry out naturally. It's necessary to mend any crevices or cracks in the base to stop them being mirrored and "travelling" up into the freshly screeded floor. An on-site survey will enable the screeding installer to pinpoint this preparation work and complete it before beginning to apply the screed layer.
To protect the screed layer and flooring materials from moisture rising up through the ground, a damp proof membrane (DPM) will have to be installed. The damp proof membrane is made out of thick polythene and various layers could be used to act as a moisture barrier and air insulating layer for the screeding.
If your home is situated in a place where radon is found a supplementary barrier layer is essential to stop radon gas from entering. An airtight membrane might be suitable in places with relatively low radon measurements, however in more extreme cases there may need to be a more complicated extraction and ventilation system to take away any ground penetrating radon.
As soon as the base has been properly prepared and any DPMs installed, a sealer or primer is then put on. Primers and sealers help the bonding process and are specialist applications matched to the kind of screed that's being applied. Due to their special nature, only professional screeding specialists in Westminster should be entrusted with using them correctly, safely and using bespoke equipment for the task.
Now is the time that under floor heating can be laid out in the correct manner and installed. Insulation panels can be laid out and the heating pipes and wires will be securely attached so that there is no movement while the screed is being poured. Under floor heating is one of the most efficient ways to heat a room and an expertly installed system will provide even level of warmth in all areas of the floor.
The screeding can now be mixed and prepared on site and poured onto the base surface. Your intended use of the room will help the screeding specialist on what kind of floor screed is best for your requirements. For advanced and quick drying screeds there'll be at least a twenty four hour delay before it can be walked on, and a further Three days minimum before you are able to lay any flooring materials. If you are looking to end up with a properly finished and hard-wearing floor surface you should stick to the manufacturer's guidelines with regard to standard and heavy duty screeds where this waiting period will be longer.
As soon as the screed has hardened it can be quality checked to establish its SR level. The test involves the use of a 2 mtr straight edge laid on the floor surface and any deviations from true are measured.
- SR1 - SR1 is the best standard and permits just 3mm of deviation from the straight-edge.
- SR2 - SR2 is the classification for normal standard industrial and commercial floors and can deviate from the straight-edge by as much as five millimetres.
- SR3 - For utility floors where the finish is relatively unimportant SR3 is the standard and should have a deviation measurement of ten millimetres or less.
There might also be a requirement for a qualified structural engineer to carry out a soundness test. The testing will make certain that your newly laid screeded surface is suitable for the load bearing requirements set down in the site survey. A drop hammer test is carried out on several areas of the screed and the outcomes noted. Any screed flooring that's got load bearing requirements must be sanctioned by a trained structural engineer applying the BS8204 guidelines.

Granolithic screeding is a kind of floor finishing technique used to provide a smooth and level surface for floor tiles, carpets or other flooring materials. It's a mixture of sand, cement, and aggregate (for instance granite or marble chips) that is applied over a concrete base. The mixture is spread evenly over the surface and levelled using a straight edge to produce a smooth and hard-wearing finish that is long-lasting and durable.
Granolithic screeding is frequently used in industrial and commercial buildings and also in high-traffic areas in residential buildings. It is also commonly used in areas where chemical and abrasion resistance are required. The resulting surface is hard and smooth, which makes it easy to maintain and clean, and provides a perfect base for other flooring products.
The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and giving it time to cure. Appropriate application and curing techniques are vital for the longevity and strength of the screed. The screed must be fully cured before any further flooring materials are installed.
Multi-Coloured Floor Screeds
The type of flooring material known as multi-coloured screeds is usually found in commercial or industrial settings. To create a distinctive and decorative finish, coloured resins, aggregates, and sealants are blended together to form these screeds. They are commonly used in areas where there is heavy footfall or machinery, as they provide a slip-resistant and durable surface that can withstand continuous wear and tear.
Multi-coloured screeds can be customised to match the branding of a business, or to create a particular visual effect in a space. They are a popular choice for facilities that require a high level of hygiene due to their simple cleaning and maintenance requirements. Coloured screeds' ability to provide a seamless finish that eliminates joints or grout lines makes them a perfect choice for cleanroom environments. The freedom to select aggregates based on shape, colour and size in coloured screeds allows architects and designers to create bespoke flooring designs that are tailored to their particular project requirements. All in all, a versatile and practical flooring solution, coloured screeds can add both function and style to any commercial or industrial space.
