Floor Screeding Harefield Greater London (UB9): A professional floor screeder can help install under floor heating, level an uneven or damaged floor or help with renovations on your Harefield home, when needed. A screed is used to create a smooth floor surface on top of a concrete sub-base and provide a good base for your choice of top flooring material. Screeding a floor allows you to provide a durable, quality finish for any room in your home or office.
FLOOR SCREEDING CONTRACTORS HAREFIELD
Whatever size room you're remodeling, a local floor screeding contractor in Harefield can provide you with the experience and proper working methods to establish a perfect base for your flooring. After assessing your project they will give you advice on the optimal choice of screeding and which strategy for laying it is most appropriate for your circumstances.
They will in addition assess if a structural engineer is needed to make certain any flex strength, load bearing and point loadings are met in accordance with the building regulations.
Bringing in a skilled and highly trained flooring specialist will ensure you get the correct type of screed for the room's proposed usage and get the maximum lifespan out of your flooring. The correct mixture of screed and the way it is laid is also vital to guarantee the final durability of your floor.
Make sure you get at least 2 or 3 price quotes for your Harefield floor screeding project and also ask to what standard you are getting each quote. The price quote might be based on what's called the SR, or Surface Regularity figure. Each of the three SR levels deliver different qualities of finish, with SR1 being the best, with the least amount of deviation over the area. This could mean that you may need to rectify any patches that might cause issues when putting down your finished flooring solution.
The regulations and guidelines set out in in the British Standards BS8204 have to be followed by all Harefield floor screeding companies and they must also hold accreditation with the manufacturers of specialist screeding materials (Gypsol, Flowcrete, Cemfloor etc.) to demonstrate their safe working practices and competence. A contractor holding accreditation demonstrates that they have been assessed and trained in the use of these products and can provide a high quality standard in all areas of their installation.
Harefield commercial screeders will be involved in screeding floors in warehouses, hospitals, factories, shopping centres, restaurants and schools.
TYPES OF SCREED
Standard Screeds - Frequently used in residential projects where the mixture of cement and sand is perfectly acceptable for basic floor traffic usage. The standard screed is a mixture of five parts sand to one of cement. The standard screed dries at a rate of one millimetre thickness each day.
Fibre Reinforced Screed - The professional's choice for residential use over the top of underfloor heating. The improved flexibility and strength provided by the fibres in the screed help protect the flooring from thermal shrinkage and cracking. The screed will set hard at a rate of roughly 1mm/day.
Industrial and Heavy Duty Screed - Designed for maximum durability and strength in areas where traffic is high or specific loading of the floor is required.
Polymer Screeds - When a decreased thickness of floor is necessary on account of construction requirements, a polymer screed provides a high strength resolution to this situation. The setting times vary as outlined by proprietary product guidelines.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is necessary this solution of cement and latex is used to create SR1 quality screeding. It's largely used to provide a clean, smooth floor over a damaged or poor quality substrate and enables all types of flooring materials to be used. Even with a depth of one millimetre, the latex polymers within the mixture provide a high strength surface for a variety of uses.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the screeded area much faster. Drying out at a rate of 3-7mm, subject to the specialised mix, they're typically a fibre reinforced screed and are perfect for flooring projects that have tight deadlines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to prepare all areas before any other work so as to ensure a hard wearing and quality screed flooring. The existing floor surfaces should be cleaned to eradicate any paint, debris, grease and oil which might adversely affect the bond of the screed.
Any cleansing products used during this process shouldn't leave any residues, and the floor surface must be allowed to dry out naturally. If screeding over a stone or cement floor then all cracks should be mended to stop them from "travelling" through a screed layer and resulting in deviations on the final floor surface. During a site survey your Harefield screeding contractor will notice what preparations are necessary before starting to work on the screeding.
To protect the flooring materials and screeding layer from moisture rising up from the ground, a damp proof membrane (DPM) will have to be installed. The DPM is made of thick polythene and various layers may be used to serve as a moisture barrier and air insulating layer for the screeding.
If the area where you live is susceptible to radon gas then one additional barrier is required to stop this harmful gas from entering via the ground. If radon gas occurs in severe doses then a complete ventilation system might be needed underneath the layer of screed which will remove any gases that could seep in from ground level.
Once the base has been prepared and all DPMs installed, a primer or sealer is then applied. Sealers and primers help with the bonding process and are specialist applications according to the type of screed being applied. Custom-made equipment such as airless sprays can be used to apply a primer or sealant, by experienced screeding contractors in Harefield following the manufacturer's guidelines.
If you're installing under floor heating, this is the time that it will need to be correctly set out and installed. Insulation panels will be put in position and the heating pipes and wires will be securely attached to prevent any movement whilst the screed is being applied. When professionally installed an under floor heating system is an effective way to warm up a room and decent quality screeding will retain its heat, producing an even heat right across the floor surface.
The screeding can now be prepared in situ and poured onto the floor base. The specific requirements of the room will determine the sort of screeding that's used. For advanced and quick drying screeds there will be at least 24 hours delay before it can be walked over, and a further 3 days minimum before you are able to lay any flooring materials. Such time periods will be longer for heavy duty and standard screeds and the manufacture's instructions must be followed to produce the optimum finish and durability of the floor.
The SR standard of your screeding can be ascertained once it has set sufficiently to be walked on. Through the use of a 2 metre straight-edge the surface is examined for any deviations, ridges and dips in the surface of the screed.
- SR1 - Over the entire floor area, if there aren't any deviations of more than three millimetres from the straight-edge, then you have a top quality SR1 standard surface.
- SR2 - SR2 is the classification for standard floors in commercial and industrial projects and can deviate from the straight-edge by as much as 5mm.
- SR3 - If the deviation is ten millimetres or less the screed quality is categorised as SR3 and is fine for utility and garage areas.
If you need to check the screeded floor for load bearing, a qualified structural engineer is required to carry out the testing. The assessment will make certain that your new screed surface is viable for the load bearing requirements set down in the site survey. A "drop hammer test" will be carried out on different areas of the screed layer and the outcomes noted. The precise testing and measurement tools mean this can only be undertaken by a trained structural engineer applying the guidelines of the British Standards BS8204.

Multi-Coloured Floor Screeds
A flooring material widely used in industrial or commercial settings is coloured screeds. These screeds are formed by mixing coloured aggregates, resins, and sealants, resulting in a distinct and decorative finish. In areas with heavy foot traffic or machinery, they are frequently utilised due to their ability to withstand wear and tear and provide a durable, slip-resistant surface.
The branding of a business or the desired visual effect in a space can be achieved by customising multi-coloured screeds. Their easy-to-maintain and clean properties make them a frequently chosen option for facilities that require a high standard of hygiene. All in all, the combination of versatility and practicality in multi-coloured screeds makes them a flooring solution that can enhance both style and function in any industrial or commercial space.
What Does Screeding Do?
Within construction projects, screeding serves several vital purposes:
- Load Distribution.
- Stability and Structural Integrity.
- Smoothing and Levelling.
- Compatibility with Floor Finishes.
- Improving Sound and Thermal Insulation.
- Corrections to Subfloors.
- Underfloor Heating System Support.
- Surface Protection.
All in all, a level, stable and durable floor surface is achieved through the vital role of screeding. The floor finish is assured of a solid foundation, ensuring its maintenance of aesthetics and quality, and ability to withstand the demands of day-to-day use for many years to come.
