Floor Screeding Willaston Cheshire (CH64): A professional floor screeding company can level an uneven or damaged floor, help install under floor heating or assist with renovations on your Willaston property, when needed. A screed is used to generate a smooth floor surface on top of a concrete sub-base and give a level base for you final flooring material. The screeding is a vital process to ensure a high quality and durable finish to the entire floor structure.
FLOOR SCREEDING EXPERTS WILLASTON
It doesn't matter how small or large the room you need levelling, a certified screeding specialist in Willaston will have the essential skills, equipment and knowledge to provide you with a superb standard of service. After a thorough evaluation of your flooring project, they will be in a position to advise you on which method of laying is most suitable for your situation, and what is the perfect choice of screed to use.
It may be necessary, contingent on the proposed use of the space, for a structural engineering survey to conform with building regulations on load bearing, point loadings and flex strength of the screed floor.
A skilled and qualified work force is imperative for a successful result and will extend the lifespan of your floor through the use of the right sort of screed for the proposed purpose of your room. The correct mix of screed and the way it is laid is also crucial to ensure the ultimate quality of your floor surface.
Before choosing a floor screeding company from any based in the Willaston area, ask to what standard of finish they are basing their quotation, and also make certain that you get multiple quotations from different screeders. The Surface Regularity (SR) finish is the figure to look for when reviewing an estimate from Willaston screeding contractors. Each of the three SR levels deliver different levels of finish, with SR1 being the best, with the least amount of deviation over the area. An SR2 or SR3 level could mean there will be ridges or flat spots that might cause issues when laying your final floor surface.
The rules and regulations specified in the British Standards BS8204 must be observed by all Willaston floor screeding contractors and they should also be accredited by the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to verify their safe working practices and competence. The testing and training of a screeding contractor by such manufacturers is highlighted by the use of the accreditation scheme, and guarantees safe working practices and reliability on any screeding project involving their materials.
Commercial screeders in Willaston will probably tackle screeding projects in warehouses, shopping centres, factories, hospitals, schools and pubs.
TYPES OF SCREED
Standard Screeds - A mixture of sand and cement which is good for basic domestic use. 5 parts sand to 1 part cement is the usual mix for standard screed. After being laid a standard flooring screed mixture dries out at a rate of 1mm/day.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is necessary, heavy duty screeds offer maximum durability and strength.
Fibre Reinforced Screed - The favoured choice by professional contractors for use in combination with underfloor heating systems. The special fibres in this screed enhance overall strength and durability whilst also safeguarding against thermal shrinkage and cracking. At approximately one millimetre per day, it has a similar curing rate to standard screed.
Liquid or Self-Levelling Screeds - A latex and cement material which can produce the highest standard SR1 finish. The self-levelling compound provides a smooth and clean surface over a damaged floor or rough substrate to enable all flooring materials to be laid. The liquid screed can be laid to a depth of only one millimetre, but still provides a high strength base to take a selection of flooring materials.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries quickly and allows you to use the screeded area much sooner. They're normally a fibre reinforced kind of screed that dries out at a rate of between 3-7mm per day and are employed in time critical projects.
Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is essential. Because of their different chemical compositions, polymer screeds have varying setting times which you can verify by reading manufacturer's own product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is vital for a high quality screed surface that will be hard wearing and durable. It's crucial that all contaminants such as oil, grease, debris or paint is eliminated from the floor surface before pouring any screed, since these can affect the bonding capability that a quality floor screed demands.
If cleaning products were used it is important to remove any traces of detergent or soap, and leave the surface to dry naturally. It is essential to repair any cracks in the floor surface to prevent them being reflected and "travelling" up into your freshly screeded floor. During an on-site survey your Willaston screeding contractor will be able to see what preparations are required before any actual screeding work begins.
Before any screeding can be poured a DPM (damp proof membrane) must be put down to protect the screed and final flooring from moisture. Different gauges of polythene sheeting might be used as a DPM and also serve as a barrier for the screed and any insulation material.
If your home is located in a place where radon gas is found an extra barrier layer is needed to stop radon gas from getting through. A simple air-tight membrane might be suitable in areas with relatively low levels of radon, but in more severe situations there might have to be a more sophisticated extraction system to take away any harmful radon.
As soon as the floor base has been prepared and all membranes installed, a primer or sealer is then put on. Sealers and primers help with the bonding process and are specialist applications specifically designed for the kind of screed that is being applied. These materials require qualified technicians to apply them in the correct proportions by using airless sprays and other tailor-made equipment.
Before the screeding is laid, any under floor heating will now be laid out. The heating pipes and cables are firmly mounted on insulation panels to prevent any movement and ensure they're laid in the correct position. Warmth will be evenly spread across a floor area in a professionally installed underfloor heating system, and in conjunction with it being an efficient choice of heating, it's a good choice for the majority of Willaston home renovation projects.
The screed can now be mixed and prepared in situ and applied to the floor surface. Your intended use of the room will assist the screeding company on which kind of floor screed is ideal for your needs. After application of the screed there'll be a minimum twenty four hours (for quick drying screeds) before you can walk over the surface, and a 72 hour minimum curing period before any floor material installations. This time period is increased for heavy duty and standard screeds and the manufacture's guidelines must be followed to the letter to create the optimum finish and longevity of the floor.
The SR standard of your screed can be verified once it has solidified sufficiently to be stepped onto. Through the use of a two metre straight-edge the floor surface is checked for any deviations, dips and ridges in the screed surface.
- SR1 - Disparities of three millimetres or less as measured over the whole floor area shows your screeding to be of the highest quality and categorised as SR1.
- SR2 - SR2 is for standard floors in commercial and industrial projects and can deviate from the straight-edge by as much as 5 millimetres.
- SR3 - If the deviation is 10 millimetres or less the screed quality is categorised as SR3 and is fine for utility and garage areas.
It might also be necessary for a qualified structural engineer to perform a soundness test. Using specialised equipment the structural engineer will ascertain the screeding strength and its suitability for use in a load bearing environment. This can include a drop hammer test which assesses various aspects of the flexibility and strength of the screed. Any screed flooring that has load bearing requirements must be sanctioned by a competent structural engineer respecting the British Standards BS8204 regulations.

Screed Reinforcement
To enhance the strength and durability of concrete screeds, screed reinforcement is utilised. The creation of level surfaces involves applying flat and thin layers of concrete known as screeds to a base layer. In building projects, they have a common use as flooring, and they can also serve as a finishing layer for walls and ceilings.
To prevent cracking and enhance strength, reinforcement materials like steel mesh, fibres or wire are included in the screed mixture during installation. Weight and load are evenly distributed across the surface by this reinforcement, which also improves its ability to resist abrasion, thermal changes and impact.
In addition to improving the screed's strength and durability, screed reinforcement also helps to reduce the risk of shrinkage and cracking caused by changes in humidity or temperature. The application of screed reinforcement is an effective way for building professionals to make sure that their projects will be able to withstand the test of time and provide a high-quality, functional surface for many years to come.
Latex Screed
When the nature of your floor's surface means that a certain degree of flexibility is required, it may be an advantage to use a latex floor screed, rather than one with a rigid finish. Latex floor screeds normally comprise two parts - a cementitious powder and a liquid latex additive. Whereby water is normally used in a screed mix, this is replaced with the latex liquid, which makes it quicker drying and more flexible than other types of screed.
This latex compound is used for levelling-out sub-floors prior to the installation of your chosen decorative surface. Producing a smooth, resilient surface that is ideal for the application of adhesives, this is is appropriate for use on sub-floors of concrete, stone tiles, sand/cement, wood and asphalt. If your sub-floor has any movement in it, this type of floor screed will produce a flexible, crack-free finish, onto which your chosen floor coverings can be laid.
Latex flooring screeds aren't appropriate where "floating" screeds are required, for instance when an unbonded screed is being laid on top of a layer of either acoustic or thermal insulation, such as could be the case when you are screeding on top of underfloor heating, and thicknesses of 50-75mm may be needed.
