FLOOR SCREEDING EXPERTS EAST HORSLEY
A professional floor screeding company in East Horsley will have experience and knowledge to help you achieve a perfect floor in whichever size room you're working on. After a thorough evaluation of your flooring project, they'll be able to advise you on which method of laying is most suitable for your situation, and what is the ideal screed to use.
A professional screeding company will also let you know if a structural engineer is required for your project, in order to evaluate flex strength, load bearing and point loadings that your screed floor may require to conform with building regulations and British Standards.
The training and skills that a certified screeding technician brings to your project should guarantee a high quality result and help to extend the lifespan of your floor or floors. Selecting the correct screeding materials and the method of installation is crucial if you want to finish up with a quality and durable finish for your floor surface.
Before selecting a floor screeding contractor from those operating in the East Horsley area, ask to what standard of finish they're basing their estimate, and also ensure that you get two or three estimates. For domestic properties a quote will usually be provided for an SR (Surface Regularity) level of SR1 or SR2. SR1 is the highest level, and whilst SR2 and SR3 might be less expensive initially, they don't guarantee a totally even or flat floor surface. Any errors or imperfections in the screeding can cause problems in laying flooring because of flat spots, ridges, indentations in the floor surface.
British Standards BS8204 sets down the guidelines and regulations that all East Horsley screeding installers is obliged to follow, and if working with specialist screeding solutions, (Cemfloor, Flowcrete, Gypsol etc), they ought to be certified by the manufacturers as being skilled and trained in their use. A contractor holding accreditation indicates they have been assessed and trained in the use of these products and can deliver a high quality standard in all aspects of their installation.
Commercial screeders in East Horsley will generally undertake larger screeding projects in schools, factories, restaurants, warehouses, shops and hospitals.
TYPES OF SCREED
Standard Screeds - This is okay for basic residential use and comprises a mix of cement and sand. The standard screed is a mix of five parts sand to one of cement. The standard flooring screed dries at a rate of 1mm thickness per day.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially in SR1 levels of screeding, by a cement and latex mixture. It is mainly used to produce a high quality floor over a damaged or poor quality substrate and results in a surface onto which all sorts of flooring materials can be laid. This liquid screed can be laid to a thickness of only 1mm, but still provides a high strength surface for a wide variety of flooring materials.
Fast Drying and Advanced Drying Screeds - If there's a need to use the floor at the earliest opportunity a fast drying screed may be used. Drying at a rate of three to seven millimetres, depending on the specialised mix, they're usually a fibre reinforced type of screed and are perfect for projects that have tight schedules.
Polymer Screeds - When a lower thickness of floor is needed due to building requirements, a polymer screed offers an extremely high strength solution to the problem. The curing times vary according to proprietary product guidelines.
Industrial and Heavy Duty Screed - Where traffic levels are high or heavy loading of the floor is necessary, heavy duty screeds provide maximum durability and strength.
Fibre Reinforced Screed - Used with underfloor heating and is the favoured choice in such projects. The increased strength and flexibility offered by the special fibres in the screed help protect the flooring from cracking and shrinkage due to heat. The screed will set hard at a rate of 1mm/day.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is vital for a quality finished screed surface that will be durable and hard wearing. Any paint, debris, oil and grease on the existing floor surface can affect the bonding of the screed, and must be eradicated.
If any cleaning products are used in this process it's vital to make certain that no residues of detergents, soaps or other cleaning products are left on the floor surface and it's allowed to dry out naturally. At this stage cracks need to be mended as these can easily travel up through the newly laid screed and be reflected in the completed surface. A site survey will enable the screeding specialist to pinpoint these preparation areas and finish them before beginning to lay the screeding.
Before any screeding can be laid a DPM (damp proof membrane) will have to be put down to shield the screed and final flooring from moisture damage. There may be 2 or 3 layers of different thicknesses of polythene to act as a barrier between the screed and the insulation layer.
If the area where you live is at risk from radon gas then one additional barrier is needed to stop the gas from entering via the ground. A simple airtight membrane could be sufficient in locations with low emissions of radon, however in more severe cases there might have to be a more complicated extraction system to take away any ground penetrating radon gases.
As soon as the floor base has been properly prepared and all membranes installed, a sealer or primer is then put on. These primers and sealers will ensure that the screed bonds perfectly to the base and help achieve a quality finished floor. Owing to their specialist nature, only professional screeding contractors in East Horsley should be entrusted with using them safely and correctly and through the use of bespoke equipment for the task.
If you're installing under floor heating, this is the time that it will need to be correctly laid out and installed. The heating pipes and cabling are firmly attached to insulation panels to prevent any movement and make certain they're held in the correct position. When expertly installed an under floor heating system is an efficient way to warm a room and high quality screed will retain its heat, producing an even heat across the floor.
If you're not fitting under floor heating the screed will now be prepared in situ and laid. Your screeding company will have given you guidance and advice on which screed type is best for your needs, according to your intended use of the room. For quick drying and advanced screeds there'll be at least 24 hours delay before it is able to be walked over, and a further 3 days minimum before you can lay any flooring materials. Manufacturer's drying instructions for heavy duty and standard screeds should be followed in order to achieve a quality finish and end up with a stable and even surface.
The SR standard of your screeding can be checked once it's set enough to be walked upon. Using a two metre straight-edge the surface is checked for any ridges, dips and deviations in the surface of the screed.
- SR1 - SR1 is the highest standard and permits just three millimetres of disparity from the straight-edge.
- SR2 - The standard flooring in commercial and industrial builds is classed as SR2 and has a maximum possible deviation of 5 millimetres across the whole screed.
- SR3 - If the deviation is ten millimetres or less the screed quality is classified as SR3 and is the standard required for garage and utility areas.
If you need to check the screeded floor for load bearing, a structural engineer is needed to conduct the tests. Using specialist equipment the engineer will assess the screeded surface strength and viability of use in a load bearing environment. An assessment called the drop hammer test is conducted at various areas on the screed and the results recorded. Only certified structural engineers following the BS8204 guidelines are allowed to conduct these testing and sign off on the structural safety of the screeding.

What Does Screeding Do?
Screeding plays a vital role in achieving several important objectives in construction projects:
- Surface Protection.
- Smoothing and Levelling.
- Stability and Structural Integrity.
- Improving Thermal and Sound Insulation.
- Underfloor Heating System Support.
- Load Distribution.
- Compatibility with Floor Finishes.
- Corrections to Subfloors.
Essentially, screeding is instrumental in achieving a stable, level and durable floor surface. By maintaining a solid foundation, it enables the floor finish to uphold its quality and aesthetics, and endure the demands of everyday use for many years to come.
Granolithic Screeding
Granolithic screeding is an extremely popular flooring material which is commonly used in heavy-duty environments because of its strength and durability. It is made from a mixture of aggregate, sand, cement, and sometimes pigments, which are combined to form a mortar-like mixture. The mixture is poured onto the floor and then smoothed out to an even, level surface.
The resulting flooring is slip-resistant, hard-wearing and easy to clean, making it ideal for use in areas with high foot traffic, such as shopping centres, schools and factories.
Granolithic screeding is typically applied over a concrete sub-base, and the surface is often treated with a curing compound to ensure it sets correctly. As soon as it has cured, it creates a seamless floor with a smooth, hard surface that is resistant to excessive wear. It's also highly resistant to chemicals and water, which makes it ideal for use in environments where there is a chance of spills or exposure to dangerous materials.
Latex Floor Screeds East Horsley
When a level of flexibility is needed in the surface of a floor you may find that using a latex screed will be an advantage. Latex screeds usually comprise two parts - a cement-based compound, and a liquid latex mixture. Latex screeds are quicker drying and more flexible than other types of screed, because the water that's normally used is substituted with the latex liquid.
This latex compound is used for levelling subfloors in advance of the laying of your chosen decorative surface. Providing a resilient, smooth surface that's perfect for the application of adhesives, this screeding is is suitable for use on sub-floors of sand/cement, asphalt, wood, stone tiles and concrete. If there is any movement in the subfloor this type of floor screed will give you a crack-free, flexible finish on which you can lay your chosen floor coverings.
Latex flooring screeds aren't appropriate where "floating" screeds are needed, for example when a screed is being laid on top of a membrane of either acoustic or thermal insulation, such as might be the case when you're screeding on top of underfloor heating, and screed depths of 50mm-65mm may be required.
