Floor Screeding Rochford Essex (SS4): When embarking on the renovation of a property or basement, addressing a damaged or uneven floor, or considering underfloor heating installation in your Rochford home, it is imperative to rely on the expertise of a floor screeding professional. The purpose of screeding is to establish a seamless and level surface over a concrete sub-base, providing a solid groundwork for your preferred flooring material. This crucial procedure ensures a robust and high-grade finish for the whole floor structure, guaranteeing its endurance and permanence. When you employ the services of a floor screeding specialist, you can rest assured that you will achieve a durable and flawless floor surface that perfectly aligns with your specific requirements.
FLOOR SCREEDING COMPANIES ROCHFORD
Supplying the experience and correct working methods to generate the perfect base for your floors, a floor screeding company in Rochford can help you with whatever size or shape of room or area you are remodeling. After evaluating your project they will advise you about the optimal choice of screed and which technique for applying it is most appropriate for your circumstances.
It may be necessary, depending on the intended use of the area in question, for a survey by a structural engineer to abide by building regulations on point loadings, load bearing and flex strength of the screed floor.
The training and skills that a qualified screeding contractor brings to your project will guarantee a high quality result and help to lengthen the lifespan of your flooring. The correct mixture of screed and the way it is laid is also crucial to ensure the ultimate durability of your floor surface.
There are a number of screeding companies in and around Rochford so make sure you get multiple quotations for your floor screeding project before picking out a contractor and know to what standard of finish is it for. For domestic properties a quotation will usually be provided for an SR (Surface Regularity) standard of SR1 or SR2. SR2 and SR3 will be cheaper options, although the finished floor surface might have errors and deviations, whilst SR1 guarantees a perfect quality of finish. Any imperfections in the final screeding can cause problems in laying flooring due to flat spots, indentations, ridges in the floor surface.
The rules and regulations set out in in the British Standards BS8204 have to be observed by all Rochford floor screeding companies and they must also hold accreditation with the manufacturers of any specialist screeding materials (Flowcrete, Cemfloor, Gypsol etc.) to demonstrate their safe working practices and competence. The testing and training of a screeding company by a manufacturer is highlighted by the use of this accreditation scheme, and offers assurances of reliability and safe working practices on any flooring project involving their materials.
Commercial screeders in Rochford will generally undertake screeding projects in salons, shopping centres, schools, warehouses, hospitals and factories.
TYPES OF SCREED
Standard Screeds - A combination of cement and sand which is okay for standard residential usage. This mixture comprises a five to one ratio of sand to cement. The standard flooring screed dries at a rate of one millimetre thickness each day.
Fibre Reinforced Screed - The preferred option for professional installers where underfloor heating is being installed in residential homes in Rochford. This is because of the increased strength and protection against thermal shrinkage and cracking offered by the fibres within the screed mix. The screed will set hard at a rate of roughly 1mm/day.
Advanced Drying and Fast Drying Screeds - If there's a need to press ahead urgently with the work because of time restraints, these screeds dry much quicker than standard flooring screeds. They're usually a fibre reinforced kind of screed which can dry at a rate of between three and seven millimetres per day and are employed in time critical projects.
Polymer Screeds - An extremely high strength solution where a reduced thickness is required. Maker's guidelines for curing times are different across the product ranges.
Industrial and Heavy Duty Screed - A screed that is designed for high load and heavy traffic areas where maximum strength and durability is essential.
Liquid or Self-Levelling Screeds - A cement and latex formula which can achieve the highest standard of finish to SR1 levels. Mainly used to improve a poor substrate level or damaged floor in order to lay a brand new flooring surface, such as tiles on top of it. Even with a depth of just 1mm, the latex polymers within the screed provide a high strength surface for a wide variety of uses.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will have to carefully prepare the area before proceeding with any other work in order to guarantee a hard wearing and quality screed flooring. It's crucial that any contaminants such as grease, oil, debris or paint is removed from the floor surface before pouring any screed, as these can affect the bonding capability that a good quality screed requires.
If cleansing products have been used it is crucial to remove any residues of soap or detergent, and leave the floor surface to dry naturally. If screeding over a stone or cement floor then all cracks should be mended to stop them from "travelling" up through the screed layer and resulting in imperfections on the finished floor surface. A trustworthy Rochford screeding installer will address such aspects during a site survey and ensure all preparations are finished before pressing on with the next stages of the screeding process.
A DPM (damp proof membrane) will be installed once the preparation work has been completed to prevent ground dampness affecting the screed and floor materials. Different gauges of polythene sheets might be used as a DPM and also act as a buffer for the screed and any insulation material.
If the area is susceptible to radon then an additional barrier is needed to prevent the gas from entering via the ground. An airtight membrane might be sufficient in places with relatively low radon emissions, but in more serious cases there may have to be a more complicated ventilation and extraction system to take away any ground penetrating radon gases.
As soon as the base has been prepared and all DPMs installed, a sealant or primer is then put on. These sealers and primers will make sure the screed bonds successfully to the base and help accomplish a good quality finished floor. These substances need qualified technicians to apply them in the correct proportions by using bespoke equipment, such as airless sprays.
Underfloor heating can now be laid out, installed and checked before the screed is applied. The wires and heating pipes are securely mounted on insulation panels to stop any movement and ensure that they are positioned correctly. Under floor heating is one of the most efficient ways to heat a room and a properly installed system will deliver even level of warmth across the floor area.
The screeding can now be mixed and prepared in situ and spread onto the base. Your screeding company will give you advice and guidance on which screed type is suitable for your needs, according to your proposed use of the room. Remember that even advanced and quick drying screeds have a minimum of 24 hours before you're able to walk over any laid surfaces and a minimum 72 hours before any floor coverings can be laid. Manufacturer's drying guidelines for standard and heavy duty screeds must be followed so as to achieve a quality finish and end up with a stable and long lasting floor surface.
The SR level of your screed can be verified once it has hardened sufficiently to be walked upon. Using a 2 mtr straight-edge the floor surface is checked for any deviations, ridges and dips in the surface of the screed.
- SR1 - Deviations of 3mm or less as measured across the entire floor area shows your screed to be of the highest quality and is classified as SR1.
- SR2 - If the floor has a deviation from the straight-edge of 5 millimetres or less it is SR2 level and is the standard for commercial and industrial floors.
- SR3 - SR3 is utility standard where a perfect finish is not needed. This classification allows for a maximium deviation of 10 millimetres.
If you need to check the floor for load bearing, a qualified structural engineer is required to carry out the tests. Using specialised equipment the engineer will ascertain the screed surface strength and its suitability for use in a load bearing environment. The screed will be given what's known as a "drop hammer test" to gauge strength and flexibility at distinct points. Only qualified structural engineers observing the BS8204 guidelines are permitted to carry out these testing and sign off on the structural integrity of the screeding.

What Does Screeding Do?
Several essential purposes are served by screeding in construction projects:
- The Even Distribution of Loads.
- Levelling and Smoothing.
- Surface Protection.
- Improving Thermal and Sound Insulation.
- Stability and Structural Integrity.
- Underfloor Heating System Support.
- Corrections to Subfloors.
- Compatibility with Floor Finishes.
In a nutshell, creating a stable, durable and level floor surface is a vital role played by screeding. By providing a solid foundation, it ensures that the floor finish maintains its quality and aesthetics, and withstands the demands of everyday use for many years to come.
Granolithic Screeding
Granolithic screeding is a process of creating a smooth and even surface for floor coverings like carpets or tiles. It involves mixing aggregate, cement and sand to form a mixture, which is then applied to a concrete sub-base. The mixture is levelled with a straight edge to give it a smooth surface.
The resulting flooring is easy to clean, slip-resistant and hard-wearing, making it ideal for use in areas with high foot traffic, such as factories, shopping centres and schools.
The granolithic screeding process involves preparation of the concrete base, mixing the screed mixture, laying the mixture, and giving it time to cure. Proper application and curing techniques are vital for the strength and longevity of the screed. The screed must be fully cured before any additional flooring is laid.
Multi-Coloured Floor Screeds
Coloured floor screeds are a type of flooring material mostly employed in industrial or commercial settings. The combination of coloured resins, aggregates, and sealants is what makes up these screeds, producing a unique and decorative finish. Areas with heavy footfall or machinery commonly utilise them as they provide a long-lasting, durable and slip-resistant surface.
To match a business's branding or create a specific aesthetic in a space, multi-coloured screeds can be customised. Their ease of cleaning and maintenance makes them a sought-after option for facilities that demand a high level of hygiene. A seamless finish, eliminating grout lines or joints, makes multi-coloured screeds an excellent flooring option for cleanrooms and similar environments. By choosing the size, shape, and colour of the aggregates used in coloured screeds, architects and designers have the ability to create custom flooring designs that are tailored to their specific project requirements. All in all, the combination of versatility and practicality in coloured screeds makes them a flooring solution that can enhance both function and style in any industrial or commercial space.
