Floor Screeding Chelsea Greater London (SW1): If you are renovating a property or basement, are planning to install underfloor heating or have an uneven or damaged floor, then you'll need to find a specialist floor screeding company to help you. To provide you with a good base for your choice of top flooring material, screeding is used to create a smooth floor surface on top of a rough concrete sub-base. Screeding a floor allows you to provide a high quality and durable finish for any room in your home.
FLOOR SCREEDING CONTRACTORS CHELSEA
Providing a superb level of service, a professional floor screeding company in Chelsea will have the appropriate expertise, know-how and equipment, regardless how large or small the area is that you require to be levelled. After a careful evaluation of your project, they will be able to inform you about which method of laying is most suitable for your floor, and what is the perfect choice of screed to use.
Your screeding specialist will also let you know if a structural engineer is needed for your undertaking, in order to evaluate flex strength, point loadings and load requirements that your screed floor might require to conform with current British Standards and building regulations.
Working with a highly trained and skilled flooring specialist will guarantee that you get the correct kind of screed for the room's intended usage and get the maximum lifespan out of the resulting flooring. The correct mixture of screed and the way it is laid is also vital to guarantee the ultimate intergrity of your floor.
There are several screeding contractors in the Chelsea area so try to get multiple estimates for your floor screeding project before choosing a contractor and know to what standard of finish is it for. For residential properties an estimate will generally be provided for an SR (Surface Regularity) standard of SR1 or SR2. Each of the 3 SR levels provide different standards of finish, with SR1 offering the best, with the smallest amount of deviation over the surface area. An SR2 or SR3 level may mean there will be flat spots or ridges that might cause issues when installing your final flooring surface (carpet, wood, tile etc).
Every Chelsea screeding company must adhere to British Standards (BS8204) and ought to have accreditation from screeding material and equipment manufacturers, e.g. Gypsol, Cemfloor, Flowcrete. This accreditation scheme demonstrates a company's training and ability in the application of a manufacturer's products.
For larger floor screeding projects in salons, schools, hospitals, warehouses, shops and factories, dedicated Chelsea commercial screeders will be required.
TYPES OF SCREED
Standard Screeds - This is okay for regular domestic usage and is a blend of cement and sand. 5 parts sand to 1 part cement is the typical mixture for standard flooring screeds. After being laid a standard screed dries out at a rate of just 1mm/day.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the floor area much faster. Most of the fast or advanced drying screeds are of the fibre reinforced kind and are appropriate for a wide array of projects where the quicker drying rate of 3-7mm/day is advantageous.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is needed, heavy duty screeds provide maximum strength and durability.
Fibre Reinforced Screed - The expert's choice for domestic use on top of underfloor heating. The special fibres in the screed improve overall strength and durability while also protecting against thermal cracking and shrinkage. It's got a setting rate of one millimetre per day.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is needed this mixture of cement and latex is employed to achieve SR1 level screed flooring. It is largely needed to produce a clean, smooth floor over a damaged or poor quality substrate and results in a finish onto which all kinds of flooring materials can be laid. These can be as little as one millimetre thick, and because of the latex polymers, will still provide a high strength finish.
Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is essential. The drying times vary in accordance with product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare all areas prior to any other work so as to ensure a high quality and hard wearing screed flooring. The existing floor surfaces should be thoroughly cleaned to eradicate any debris, paint, oil and grease which can adversely affect the bond of the screeding.
If cleansing products have been used it's essential to remove any traces of detergent, soap etc, and leave the floor surface to dry naturally. It is necessary to mend any crevices or cracks in the base to avoid them being mirrored and "travelling" up into your newly screeded floor. A professional Chelsea screeding company will address such problems during the site survey and make certain all preparations are complete before moving on to the next stages of the floor screeding process.
To shield the flooring materials and screed layer from moisture rising up from the ground, a damp proof membrane (DPM) must be laid. The damp proof membrane is made of thick polythene sheeting and different layers might be used to act as a moisture barrier and air insulating layer for the screed.
If the area where you live is susceptible to radon then an additional barrier is essential to stop the gas from entering from the ground. This can be just a simple air-tight membrane, or in severe instances an extraction and ventilation system will be installed under the floor screed to draw out any inflow of radon gas from the ground.
The final phase of surface preparation is the painting or spraying of a primer or sealant. Sealers and primers help with the bonding process and are special applications matched to the type of screed that is being used. Due to their specialist nature, only certified screeding specialists in Chelsea should be entrusted with using them correctly, safely and using bespoke equipment for the task.
If you are installing underfloor heating, this is the time that it will need to be properly set out and installed. The underfloor heating system is laid out in the correct pattern and firmly secured to insulation panels to stop potential movement during screed pouring. Warmth is spread evenly across the floor in an expertly fitted under floor heating system, and with it being an efficient choice of heating, it's a great choice for the majority of Chelsea renovation projects.
Naturally, if you are not putting in under floor heating, you can bypass this step and get on with applying the floor screed. The specific requirements of the room will determine the form of screeding that's used. For quick drying and advanced screeds there'll be at least twenty four hours delay before it is able to be walked on, and a further Three days minimum before any flooring material can be applied. If you are using heavy duty or standard screeds the drying time is longer and the manufacturer's guidelines must be adhered to so as to get the best finish for your floor.
The SR standard of your screed can be verified once it has hardened sufficiently to be stepped onto. The test involves the use of a two metre straight edge laid down upon the floor surface and any deviations from true are calculated.
- SR1 - SR1 is the highest quality and allows just 3mm of deviation from the straight-edge.
- SR2 - SR2 is the classification for normal standard floors in industrial and commercial projects and can deviate from the straight-edge by as much as 5mm.
- SR3 - For a utility area or room where the quality of finish is comparatively immaterial the SR3 is the classification and has a maximum deviation measurement of 10 millimetres or less.
If your screeding has been laid with particular load bearing requirements in mind then a structural engineer will be required to perform the tests. This assessment will ascertain the overall strength of the screed and the suitability for its intended use. The screed could be subjected to a drop hammer test to gauge flexibility and strength at specific points. Only certified structural engineers heeding the British Standards BS8204 regulations are permitted to carry out such testing and sign off on the structural integrity of screed flooring.

Granolithic Screeding Chelsea
Granolithic screeding is a process of creating an even and smooth surface for floor coverings like tiles or carpets. It involves mixing cement, sand, and aggregate such as granite or marble chips to form a mixture, which is then applied to a concrete base. The mixture is levelled with a straight edge to give it a smooth surface.
Granolithic screeding is commonly 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 essential. The resulting surface is hard and smooth, which makes it easy to maintain and clean, and provides an outstanding base for other flooring products.
The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and allowing it to cure. Proper application and curing techniques are crucial for the longevity and strength of the screed. The screed must be completely cured before any additional flooring materials are installed.
Latex Screeds Chelsea
It is better to use a latex self-levelling screeding when a bit of flexibility is required in a floor's surface. Latex floor screed comes in two parts, a bag and a bottle, with the bag containing a cement based smoothing compound, and the bottle containing a liquid latex. Whereby water is normally used in a screed mix, this is replaced with the latex liquid, which makes it more flexible than other types of screed, and quicker drying.
This latex screed compound is used to level-out a sub-floor prior to the final decorative surface being installed. Suitable for subfloors of concrete, asphalt, quarry tiles, sand/cement and wood, this gives the ideal surface for the application of flooring adhesives which is also smooth and resilient. If your subfloor has a bit of movement in it, this type of latex screed will still give you a flexible, crack-free finish, on which your chosen floor coverings can be laid.
Latex flooring screeds aren't suitable where "floating" screeds are desired, for instance when an unbonded screed is being laid over a membrane of either thermal or acoustic insulation, such as could be the case when you are screeding over underfloor heating, and depths of 50mm-65mm may be needed.
