Floor Screeding Biggin Hill Kent (TN16): If you are renovating a property or basement, have a damaged or uneven floor or are aiming to install underfloor heating in your Biggin Hill home, then it is a good time to think about bringing in a professional floor screeder. Before you're able to lay a suitable floor covering, be it wood, carpet or tile, the surface of the floor should be as flat as possible; this is why floor screeding is sometimes essential. If you want your floors to last a long time then a floor screed is one of the most important factors in any building or renovation project.
FLOOR SCREEDING COMPANIES BIGGIN HILL
It does not matter how big or small the room is that you need levelling, a decent screeding specialist in Biggin Hill will have the essential expertise, equipment and knowledge to provide you with a superb level of service. They'll be ready to advise you on the correct sort of screed that your project requires, and the best methods for applying and installing it.
A professional screeding specialist will also inform you if a structural engineer is required for your undertaking, to check on flex strength, point loadings and load bearing that your screed floor might require to conform with British Standards and building regulations.
Bringing in a qualified and skilled contractor will guarantee you use the right type of screed for the room's intended usage and get the optimum lifespan out of the resulting floor. The correct blend of screed and the techniques used in laying it are also vital to guarantee the final intergrity of your floor.
Before deciding on a floor screeding specialist from those based in the Biggin Hill area, ask to what standard of finish they're basing their quotation, and also ensure that you get two or three quotes. The SR (Surface Regularity) finish is the number to watch out for when reviewing a quotation from Biggin Hill floor screeding contractors. SR2 and SR3 could be less costly options, but the finished floor surface might have errors and deviations, whilst SR1 guarantees a perfect quality of finish. Any errors or imperfections in the screeding can cause problems in laying flooring because of indentations, flat spots, ridges in the surface.
The regulations laid down in the British Standards BS8204 must be observed by all Biggin Hill floor screeding contractors and they must also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to substantiate their safe working practices and competence. The training and assessment of a screeding contractor by a manufacturer is emphasised through this accreditation scheme, and offers assurances of reliability and safe working practices on any flooring project which involves their materials.
Biggin Hill commercial screeders might be involved in screeding floors in warehouses, factories, shops, hospitals, schools and boutiques.
TYPES OF SCREED
Standard Screeds - A mix of cement and sand which is perfect for normal domestic usage. Five parts sand to one part cement is the usual mix for standard flooring screeds. The standard flooring screed dries at a rate of 1mm thickness each day.
Polymer Screeds - When a reduced thickness of floor is necessary due to building factors, a polymer screed provides a high strength solution to the situation. Because of their different chemical compositions, these screeds have varying drying times which can be verified by studying manufacturer's guidelines.
Liquid or Self-Levelling Screeds - Used to provide the highest quality of finish, especially in SR1 levels of screeding, by a latex and cement material. Typically used to improve a poor substrate level or damaged floor in order to lay a new flooring surface, such as tiles over it. Even with a depth of just 1mm, the latex polymers within the screed provide a high strength surface for a variety of uses.
Advanced Drying and Fast Drying Screeds - If there's a need to progress urgently with the work because of time restraints, these screeds dry more speedily than standard screeds. The vast majority of the fast drying screeds are of the fibre reinforced kind and are perfect for a wide range of projects where the faster drying rate of 3-7mm/day is a considerable advantage.
Industrial and Heavy Duty Screed - Where traffic levels are high or heavy loading on the floor is necessary, heavy duty screeds offer maximum durability and strength.
Fibre Reinforced Screed - The first choice where underfloor heating is being installed in domestic homes in Biggin Hill. The greater strength and flex provided by the fibres in this screed mix help protect the floor from cracking and shrinkage due to heat. The screed will set hard at a rate of 1mm/day.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a quality finished screed surface that will be hard wearing and durable. Any debris, grease, oil and paint on the original floor surface can affect the bonding of the screed, and must be eliminated.
If cleaning products were used it is important to remove any traces of soap, detergent etc, and leave the floor surface to dry naturally. It is essential to repair any cracks in the base to avoid them being reflected and "travelling" upwards into your newly screeded floor. A site survey will enable the screeding specialist to highlight these preparation areas and complete them before commencing to pour the screeding layer.
Before any screeding can be poured a damp proof membrane (DPM) must be put down to protect the final flooring and screed from dampness. There may be two or three layers of different thickness polythene to act as a barrier between the screed and the insulation layer.
A supplementary airtight barrier could be required if your property is in a location that's regarded as prone to radon gas emissions. If radon occurs in large amounts then a full extraction and ventilation system might be needed under the layer of screed which will remove any gases that might seep in from the ground.
Once the base has been properly prepared and any DPMs installed, a primer or sealer is then put on. A primer assists in the screed bonding process to the base surface and different varieties exist based upon which kind of screed is being used. Custom-made equipment such as airless sprays will usually be used to apply a sealant or primer, which should be done by qualified screeding companies in Biggin Hill observing the manufacturer's guidelines and safety advice.
Before any screed is poured, any under floor heating (if required) will now be laid out. The cabling and heating pipes are securely mounted on insulation panels to stop any movement and make certain they're held in the correct position. When skillfully installed an underfloor heating system is an excellent way to warm up a room and high quality screed retains its heat, generating an even heat across the floor surface.
The screed can now be mixed and prepared on site and spread onto the base surface. Your intended use of the room will assist the screeding company on what kind of floor screed is right for your needs. Be aware that even quick drying screeds have a minimum of 24 hours before you're able to walk over any screeded surfaces and a minimum 72 hours before any flooring materials can be applied. Manufacturer's drying guidelines for heavy duty and standard screeds must be observed in order to achieve a quality finish and end up with a stable and long lasting surface.
You can test the SR level of the finished screeding once it's solidified enough to walk on. The test involves using a 2 metre long straight-edge laid on the floor surface and any deviations from true are measured.
- SR1 - Deviations of 3mm or less being measured over the entire floor area shows your screeding to be of the best quality and specified as SR1.
- SR2 - The standard flooring in industrial and commercial builds is normally SR2 and has a maximum deviation of 5 millimetres across the entire floor surface.
- SR3 - For a utility area or room where the quality of finish is relatively unimportant SR3 is the standard and has a maximum deviation measurement of 10 millimetres or less.
If your screeding has been installed with specific loading in mind then a structural engineer will be necessary to perform these soundness tests. Using specialised equipment the engineer will ascertain the screeded surface strength and viability of use in a load bearing environment. An assessment called the "drop hammer test" will be performed on several areas of the screed layer and the results noted. The precise testing and measurement tools mean this can only be undertaken by a qualified structural engineer respecting the British Standards BS8204 guidelines.

Latex Screed Biggin Hill
When a certain degree of flexibility is needed in a floor's surface you might find that using a latex self-levelling screed will be advantageous. Latex screeds come in 2 parts - a bag and a bottle - with the bottle containing latex liquid and the bag containing a cement based smoothing compound. The liquid latex solution takes the place of the water which is used in other types of screed, making it more flexible and quicker drying.
This latex product is used for levelling sub-floors prior to the laying of the final decorative surface. This screeding is suitable for use on sub-floors of asphalt, concrete, sand/cement, wood and stone tiles, to provide a resilient, smooth surface that's perfect for the application of adhesives. Even if there is a bit of movement on your subfloor, this type of latex screed will produce a crack-free, flexible finish.
When using a "floating" screed, i.e. when screed is being laid on top of underfloor heating, thicknesses of 50 to 75 millimetres may be desirable, and latex flooring screeds are not appropriate in this instance.
