Floor Screeding Shavington Cheshire (CW2): If you are aiming to install under floor heating, have a damaged or uneven floor or are restoring a property or cellar in your Shavington property, then it is the perfect time to consider hiring a professional floor screeding company. To provide you with a level base for your choice of top flooring material, a screed is used to generate a smooth floor surface over a rough concrete sub-base. Floor screeding can provide a durable, quality surface for virtually any room.
FLOOR SCREEDING CONTRACTORS SHAVINGTON
An established floor screeding company in Shavington will have experience and knowledge to help you achieve a perfectly finished floor in whatever shape or size of room you are renovating. To determine the right form of screed you need, and the most effective way to install it, they will do a painstaking evaluation of your project.
They will also assess if a structural engineer is required to make certain that any point loadings, flex strength and load requirements are met as outlined by construction and building regulations.
Skilled and qualified trades-people are necessary for a successful outcome and will extend the life of your floor through the use of the correct type of screed for your room's anticipated purpose. Choosing the correct screeding materials and the best installation technique is vital if you want a durable and quality finish for your floor surface.
Make sure that you get at least two or three price quotes for your Shavington based screeding project and also ask what standard of finish each quote is for. For residential homes a quote will generally be given for an SR (Surface Regularity) calculation of SR1 or SR2. SR1 is the best quality, and while SR2 and SR3 might be more cost-effective initially, they don't guarantee a totally flat or even surface. An SR2 or SR3 level might mean there are flat spots or ridges that might cause issues when installing your final floor surface.
Every Shavington screeding company has to follow British Standards (BS8204) and ought to have some kind of accreditation from screeding material and equipment manufacturers, e.g. Gypsol, Flowcrete, Cemfloor. The training and testing of a floor screeding company by a manufacturer is highlighted by the use of the accreditation scheme, and offers assurances of safe working practices and reliability on any flooring project involving their materials.
Shavington commercial screeders may be involved in the screeding of floors in hotels, schools, warehouses, factories, shopping centres and hospitals.
TYPES OF SCREED
Standard Screeds - Frequently used in domestic flooring projects where the blend of cement and sand is acceptable for normal floor traffic use. This mix uses a five to one ratio of sand to cement. The standard flooring screed dries at a rate of 1mm thickness per day.
Industrial and Heavy Duty Screed - A screed that's designed for high load and heavy traffic areas where maximum strength and durability is vital.
Polymer Screeds - An extremely high strength flooring solution where a reduced screed thickness is necessary. On account of their different chemical compositions, polymer screeds have varying setting times which you can verify by checking manufacturer's own product guidelines.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries quickly and allows you to use the screeded area much faster. Drying at a rate of three to seven millimetres, depending on the mixture, they're normally a fibre reinforced screed and are perfect for flooring projects that have tight schedules.
Fibre Reinforced Screed - The favoured choice by professional screeders for use with under floor heating systems. The greater strength and flexibility offered by the fibres in the screed mix help protect the resulting floor from cracking and shrinkage due to heat. The screed will dry out at a rate of 1mm/day.
Self-Levelling or Liquid Screeds - When a high standard of finish is required this compound of cement and latex is used to achieve SR1 quality floor screeding. Mostly used to improve a poor substrate level or damaged floor to enable the laying of a brand new flooring surface, such as tiles over the top of it. The liquid screed can be poured to a depth of only one millimetre, but still provides a high strength surface to take a wide variety of flooring finishes.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish that's durable and hard wearing, time must be spent on fully preparing the area prior to any screeding material being poured. The original floor surface should be thoroughly cleaned to remove any paint, grease, oil and debris that might affect the bond of the screed.
If cleaning products were used it is crucial to remove any remnants of detergent, soap etc, and leave the surface to dry naturally. If screeding over a stone or cement floor any cracks should be mended to prevent them from "travelling" up through the screed layer and producing deviations on the finished surface. During an on-site survey the screeding contractor will ascertain what preparation work is required before starting to work on the actual screeding.
A damp proof membrane (DPM) will be put down after the preparation work has been finished to stop ground dampness affecting the flooring materials and screed. The DPM is made from thick polythene sheeting and different layers may be used to serve as a moisture barrier and air insulating layer for the screeding.
If your property is situated in an area where radon is found an extra barrier layer is necessary to prevent radon gas from entering. A simple airtight membrane might be enough in places with relatively low emissions of radon, however in more extreme cases there might need to be a more complicated extraction system to remove any ground penetrating radon gases.
The final stage of the surface preparation process is the spraying or painting of a sealant or primer. These sealers and primers will ensure that the screed bonds properly to the floor base and help create a top quality finished floor. Devices such as airless sprays are used to apply a sealant or primer, by certified screeding installers in Shavington following the manufacturer's guidelines.
Before any screed can be laid, any underfloor heating (if required) will now set out and installed. The wires and heating pipes are securely attached to insulation panels to stop any movement and ensure they're positioned correctly. Warmth will be evenly spread across the floor in a properly installed underfloor heating system, and coupled with it being an efficient method of heating, it is an ideal choice for many Shavington renovation projects.
Of course, if you're not installing underfloor heating, you simply bypass this step and get on with applying the screeding. Your screeding contractor will give you advice and guidance on which type of screed is appropriate for your requirements, according to your proposed use of the room. After the pouring of the screed there'll be at least 24 hours (for quick drying screeds) before you are able to walk over the surface, and a 72 hour minimum curing period for the laying of any floor coverings. If you are aiming to end up with a properly finished and long-lasting floor surface you must stick to the manufacturer's guidelines with regard to standard and heavy duty screeds where the waiting period will be increased.
The SR level of your screeding can be ascertained once it has solidified sufficiently to be walked upon. The test involves the use of a 2 metre long straight-edge laid on the floor surface and any deviations from true are calculated.
- SR1 - Over the entire area, if there aren't any deviations of more than 3mm from the straight-edge, then you've got a top quality SR1 standard surface.
- SR2 - If the screed has a deviation from the straight-edge of 5 millimetres or less it is SR2 level and is the normal standard for industrial and commercial floors.
- SR3 - For other floors where the finish is fairly unimportant the SR3 is the specification and has a deviation measurement of 10 millimetres or less.
If you require load bearing checks, a structural engineer is necessary to conduct the tests. This test will determine the overall strength of the screeded surface and its viability for the intended use. The screed layer could be given what's known as a "drop hammer test" to determine strength and flexibility at different points. The precise testing and measurement tools needed mean this can only be undertaken by a competent structural engineer observing the British Standards BS8204 guidelines.

Latex Screeding Shavington
When the make-up of your floor's surface means that a bit of flexibility is needed, it may be an advantage to use a latex self-levelling screed, rather than one with a rigid finish. A latex floor screed comes in two parts, a bag and a bottle, with the bag containing a cement based powder, and a bottle that contains a liquid latex mixture. The liquid latex additive replaces the water that would normally be used for mixing screed, and is quicker drying and far more flexible than standard screeds.
Used in the levelling of subfloors, this latex product provides a suitable surface for the laying of the final floor finishes. This screed is appropriate for use on substrate of wood, asphalt, sand/cement, concrete and quarry tiles, to provide a resilient and smooth surface which is ideal for the application of adhesives. This type of floor screed will provide a crack-free, flexible finish, even if there's movement in your subfloor.
When using a "floating" screed, for instance when screeding is being laid on top of underfloor heating, thicknesses of 50 to 65 millimetres may be required, and latex flooring screeds are not appropriate in this case.
Granolithic Screeding
Granolithic screeding is a popular flooring material that's used widely in heavy-duty environments due to its durability and strength. 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 a level surface.
The resulting flooring is easy to clean, hard-wearing and slip-resistant, making it ideal for use in areas with high foot traffic, such as schools, shopping centres and factories.
The granolithic screeding process involves a number of steps, including preparation of the concrete base, mixing of the screed mixture, laying of the mixture, and curing of the screed. Correct mixing, curing and application methods are crucial to guarantee the durability and strength of the final surface. Additionally, the screed should be allowed to cure fully before any flooring materials are laid on top of it.
What Does Screeding Do?
In construction projects, screeding fulfills several vital roles:
- Subfloor Corrections.
- Even Load Distribution.
- Smoothing and Levelling.
- Support for Underfloor Heating Systems.
- Stability and Structural Integrity.
- Improving Thermal and Sound Insulation.
- Surface Protection.
- Compatibility with Floor Finishes.
Essentially, the creation of a durable, level and stable floor surface is significantly influenced by the role of screeding. By maintaining a solid foundation, it enables the floor finish to uphold its quality and aesthetics, and endure the demands of everyday use for years to come.
Screed Floor Removal
To remove a screed floor, one must extract and eliminate the pre-existing screed from the surface. It is sometimes necessary when upgrading or renovating a a floor in Shavington. Achieving the effective breakdown and removal of the screed layer in the removal process requires the use of specialised equipment and techniques. The surface can be prepared for new flooring or other alterations, thanks to this. Skilled contractors in screed removal guarantee the safe and efficient elimination of the old screed, enabling a renewed beginning for the floor, be it for repairs, upgrades or changes in design.
