Floor Screeding Oswaldtwistle Lancashire (BB5): When embarking on the renovation of a property or basement, addressing a damaged or uneven floor, or considering underfloor heating installation in your Oswaldtwistle home, it is imperative to rely on the expertise of a floor screeding expert. The objective of screeding is to create a level and uninterrupted surface atop a concrete sub-base, offering a robust foundation for your favoured flooring material. This key process assures a high-quality and resilient finish for the entire floor structure, making it long-lasting and durable. By utilising the skills of a floor screeding specialist, you can ensure the creation of a seamless and enduring floor surface that precisely satisfies your individual requirements.
FLOOR SCREEDING COMPANIES OSWALDTWISTLE
An established screeding contractor in Oswaldtwistle will have all the know-how and experience to help you achieve a perfect floor in whichever shape or size of room you're working on. After a diligent evaluation of your screeding project, they'll be in a position to inform you about which method of laying is best suited to your circumstances, and which is the ideal kind of screed to use.
Your screeding specialist will also inform you if a structural engineer is necessary for your undertaking, in order to identify load requirements, point loadings and flex strength that your flooring might need to conform with current building regulations and British Standards.
Bringing in a qualified and highly trained flooring specialist will ensure you use the correct form of screed for the room's intended purpose and get the optimum lifespan out of the resulting floor. Choosing the correct screeding materials and the best installation technique is crucial if you want to finish up with a durable and quality finish for your floor surface.
Before deciding on a screeding specialist from any operating in the Oswaldtwistle area, ask to what standard of finish they are basing their quote, and also make sure that you get two or three quotes. For domestic properties a quotation will normally be given for a Surface Regularity (SR) level of SR1 or SR2. Each of the three SR levels provide different standards of finish, with SR1 offering the highest quality, with the lowest amount of deviation over the surface area. Any errors or imperfections in the final screeding can cause problems in laying flooring owing to ridges, flat spots, indentations in the surface.
The rules and regulations laid down in the British Standards BS8204 have to be observed by all Oswaldtwistle floor screeding contractors and they must also be accredited by the manufacturers of any specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to confirm their safe working practices and competence. A company holding accreditation indicates that they have been trained and assessed in using these screeding products and can provide a high standard of service in all areas of their installation.
For larger screeding projects in schools, pubs, hospitals, factories, warehouses and shopping centres, specialist Oswaldtwistle commercial screeders will be required.
TYPES OF SCREED
Standard Screeds - A blend of cement and sand which is ideal for basic residential use. The ratios involved in standard screeds are 5 parts sand to 1 part cement. Once its been laid this 5:1 ratio will dry at a rate of one millimetre per day.
Polymer Screeds - A high strength flooring solution where a reduced thickness is required. The drying times vary as outlined by product guidelines.
Self-Levelling or Liquid Screeds - When the highest possible standard of finish is necessary this blend of cement and latex is used to create SR1 quality screed flooring. This self-levelling compound provides a clean and level surface over a damaged floor or rough substrate to enable all forms of flooring materials to be laid. This liquid screed can be laid to a thickness of only 1mm, but will still provide a high strength base to take a wide range of flooring finishes.
Fibre Reinforced Screed - The expert's choice for residential use over the top of underfloor heating. The improved flexibility and strength offered by the fibres in the screed mix help protect the resulting floor from thermal shrinkage and cracking. The screed will dry out at a rate of 1mm/day.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum strength and durability is necessary.
Fast Drying and Advanced Drying Screeds - If you have to progress urgently with the work on account of time limitations, these screeds dry much faster than standard screeds. Drying out at a rate of three to seven millimetres, determined by the specialised mix, they're normally a fibre reinforced kind of screed and are perfect for flooring projects that have tight deadlines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to prepare all areas before proceeding with any other work in order to guarantee a hard wearing and quality screed flooring. It's vital that any contaminants such as paint, grease, oil or loose debris is eliminated from the floor surface before pouring any screed, because these can affect the adhesion process that a quality floor screed demands.
If any products were used during this stage it is crucial to ensure that no residues of soaps or detergents are left on the floor surface and it's allowed to dry out naturally. If screeding over a cement or stone floor then all cracks should be repaired to stop them from "travelling" up through the screed layer and producing imperfections on the final surface. During a site survey your Oswaldtwistle screeding contractor will notice what preparation work is needed before any actual screeding work commences.
Before any screeding can be poured a DPM (damp proof membrane) must be put down to shield the final flooring and screed from dampness. The damp proof membrane is made of thick polythene sheet and different layers could be used to serve as a moisture barrier and air insulating layer for the screed.
An additional airtight barrier may be required if your property is in an area that is known to be prone to radon gas emissions. An airtight membrane might be enough in areas with relatively low emissions of radon, however in more serious situations there might have to be a more sophisticated extraction system to take away any ground penetrating radon gases.
As soon as these steps have been taken the screeders will apply a sealer or primer to the prepared floor base. Primers help with the bonding process and are special applications matched to the sort of screed that's being applied. These substances need qualified technicians to apply them in the appropriate ratios by using airless sprays and other custom-made equipment.
Before the screeding is laid, any underfloor heating (if required) will now be laid out. The cables and heating pipes are securely mounted on insulation panels to prevent any movement and ensure they are positioned correctly. Underfloor heating is one of the most effective ways to heat a room and a properly installed system should provide even warmth all over the floor.
The screeding can now be mixed and prepared in situ and spread onto the base surface. The specific requirements of the room will determine the type of screeding that's used. After the pouring of the screed there'll be at least twenty four hours (for advanced and quick drying screeds) before you are able to walk on the surface, and a 72 hour minimum setting period for the laying of any flooring materials. If you are using standard or heavy duty screeds the setting time is longer and the manufacturer's guidelines must be followed so as to get the best possible finish to your floor.
As soon as the screeding has hardened it can be quality checked to confirm its SR standard. The test involves the use of a 2 metre straight edge laid on the surface and any deviations from true are measured.
- SR1 - SR1 is the best level and permits just 3 millimetres of deviation from the straight-edge.
- SR2 - The standard flooring in commercial and industrial builds is normally SR2 and has a maximum deviation of 5mm across the whole screeded surface.
- SR3 - For other floors where the quality of finish is comparatively immaterial the SR3 is the standard and should have a maximum deviation measurement of 10mm or less.
If your screed has been laid with specific load bearing requirements in mind then a qualified structural engineer is going to be necessary to carry out tests. The assessment will make sure that your newly laid screed surface is viable for the load bearing requirements laid out in the site survey. The screed could be subjected to a "drop hammer test" to gauge flexibility and strength at various points. Any screed flooring that has load bearing requirements must be sanctioned by a competent structural engineer applying the BS8204 regulations.

Multi-Coloured Floor Screeds
Multi-coloured screeds refer to a type of flooring material that is mostly used in industrial or commercial settings. By mixing coloured aggregates, resins, and sealers, these screeds are produced, resulting in a one-of-a-kind, decorative finish. They are commonly used in areas where there is machinery or heavy foot traffic, as they provide a slip-resistant and durable surface that can withstand a lot of wear and tear.
Multi-coloured screeds provide the flexibility to match the brand of a business or achieve a desired aesthetic in a space through customisation. Facilities that demand a high standard of hygiene often select them due to their ease of maintenance and cleaning. The seamless finish that coloured screeds offer, eliminating grout lines or joints, makes them an ideal flooring solution for cleanrooms and similar environments. The freedom to select aggregates based on size, shape, and colour in coloured screeds allows architects and designers to create bespoke flooring designs that are tailored to their specific project parameters. Overall, the versatility and practicality of multi-coloured floor screeds make them a flooring solution that can provide both style and function to any commercial or industrial space.
Latex Floor Screeds Oswaldtwistle
When the make-up of your floor's surface means that a bit of flexibility is necessary, it may be an advantage to apply a latex screed, rather than one with an unyielding finish. Latex floor screeds come in two parts - a bag and a bottle - with a bottle that contains liquid latex, and a bag that contains a cement powder. Latex screeds are more flexible and quicker drying than standard screeds, since the water which is normally used is exchanged for the liquid latex.
This latex screed product is used to level-out a subfloor before the final decorative surface is laid. This screeding is appropriate for use on sub-floors of quarry tiles, asphalt, concrete, wood and sand/cement, to give a smooth and resilient surface which is perfect for the application of flooring adhesives. Even when there's movement on your sub-floor, this latex screed will give you a flexible, crack-free finish.
With "floating" screeds, for example when a screed is being laid over a layer of either acoustic or thermal insulation, latex screeds won't be a suitable choice. Floating screeds with a thickness of 50mm-75mm are usually used on top of underfloor heating.
Granolithic Screeding Oswaldtwistle
Granolithic screeding refers to a type of flooring that consists of a mixture of sand, cement and aggregate. It is applied in a relatively thin layer and then smoothed to provide a durable, hard-wearing and seamless surface. It is frequently used in industrial, commercial and public buildings where there's heavy foot or machinery traffic.
This technique is typically used in commercial and industrial buildings, high-traffic residential areas, and spaces that require abrasion and chemical resistance. The resulting surface is durable, easy to clean, and provides the perfect base for other flooring materials.
The granolithic screeding process involves several steps, including preparing the concrete sub-base, blending of the screed mixture, laying of the mixture, and curing of the screed. Correct mixing, curing and application techniques are crucial to ensure the durability and strength of the granolithic screed. In addition, the screed should be allowed to fully cure before any further flooring materials are laid over it.... READ MORE.
