FLOOR SCREEDING CONTRACTORS CAINSCROSS
Providing an excellent standard of service, a genuine screeding company in Cainscross will have the appropriate expertise, equipment and know-how, regardless how big or small the area you require to be levelled. They will be able to assess the project and ascertain the correct kind of screed you need and the best technique for applying it.
It might be a requirement, based on the intended use of the area, for a structural engineering survey to conform to building regulations on load bearing, flex strength and point loadings of the screed floor.
A qualified and skilled work force is imperative for a successful outcome and will extend the lifespan of your floor by using the right kind of screed for your room's intended purpose. Selecting the appropriate screeding materials and the best installation technique is critical if you want to end up with a durable and quality finish for your floor.
There are many screeding specialists in the Cainscross area so see if you can get multiple price quotes for your project before picking a company and know to what standard of finish is it for. For residential homes a quote will usually be provided for an SR (Surface Regularity) calculation of SR1 or SR2. SR2 and SR3 will be more affordable options, although the finished floor surface may have errors and deviations, whilst SR1 guarantees a perfect finish. This means that you might have to correct any patches that might cause issues when putting down your final flooring material.
All Cainscross screeding companies have to observe British Standards (BS8204) and ought to have some kind of accreditation from the manufacturers of specialised screeding materials and equipment, e.g. Flowcrete, Cemfloor, Gypsol. This accreditation scheme illustrates a company's training and ability in the application of a manufacturer's products.
Cainscross commercial screeders may be involved in the screeding of floors in hospitals, warehouses, restaurants, schools, factories and shopping centres.
TYPES OF SCREED
Standard Screeds - This is perfect for everyday domestic usage and is a blend of cement and sand. The standard screed is a mixture of five parts sand to one of cement. The standard flooring screed dries at a rate of one millimetre thickness per day.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially where SR1 levels are necessary, by a cement and latex compound. This self-levelling compound provides a smooth and clean surface over a rough substrate or damaged floor to allow all types of flooring materials to be laid. They can be as little as one millimetre in depth, and thanks to the latex polymers, will still provide high strength.
Fibre Reinforced Screed - Used with under floor heating systems and is the preferred choice in these projects. The improved flexibility and strength provided by the fibres in this screed mix help protect the floor from thermal cracking and shrinkage. At roughly 1mm per day, it has a similar curing rate to standard screed.
Polymer Screeds - When a decreased thickness of floor is required due to construction factors, a polymer screed provides an extremely high strength resolution to the situation. Polymer screeds are made by a number of manufacturers and on account of their diverse chemical compositions have specific curing times for each product.
Advanced Drying and Fast Drying Screeds - If you have to use the floor at the earliest opportunity a fast drying screed may be used. The majority of the fast drying screeds are of the fibre reinforced kind and are appropriate for a wide range of flooring projects where the faster drying rate of three to seven millimetres is advantageous.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading on the floor is necessary, heavy duty screeds offer maximum durability and strength.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish that is durable and hard wearing, time should be devoted to fully preparing the area prior to any screed being laid. The existing floor surface should be cleaned to eradicate any grease, paint, oil and debris which can adversely affect the bond of the screeding.
Any cleansing chemicals which are used during this phase should leave no residues, and the floor base must be permitted 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 your screed layer and producing imperfections on the finished surface. A site survey will allow your Cainscross screeding specialist to take note of this preparation work and finish it before starting to pour the screeding layer.
A DPM (damp proof membrane) will be installed after the preparation work has been concluded to prevent ground dampness getting into the flooring materials and screeding. There may be 2 or 3 layers of varying thicknesses of polythene to act as a barrier between the insulation layer and screed.
If the area where you live is susceptible to radon gas then a further barrier is needed to prevent the gas from entering via the ground. This can be just a simple airtight membrane, or in more serious instances an extraction and ventilation system is installed beneath the screeding to extract any inflow of radon gas from ground level.
Once the floor base has been prepared and all DPMs installed, a sealer or primer is then put on. These sealers and primers will make sure the screed bonds effectively to the base and help achieve a quality finished floor. These products require certified technicians to apply them in the appropriate proportions by using airless sprays and other custom-built equipment.
Before the screeding is laid, any underfloor heating (if required) will now be laid out. Insulation panels can be positioned and the cabling and heating pipes will be securely fastened so there's no movement while the screed is being poured. Underfloor heating is one of the most effective ways to heat a room and an expertly installed system should provide even level of warmth in all areas of the floor.
If you're not putting in underfloor heating the screed can now be prepared in situ and poured. Your proposed use of the room will assist the screeding specialist on which sort of screed is right for your requirements. After application of the screed there will be at least twenty four hours (for quick drying and advanced screeds) before you can walk upon the surface, and a 72 hrs minimum setting time for the laying of any floor coverings. This time period is increased for heavy duty and standard screeds and the manufacture's instructions must be followed to the letter to achieve the best finish and longevity of the floor.
The SR level of your screed can be checked once it has hardened sufficiently to be walked upon. The test involves using a 2 metre straight edge laid on the surface and any variations from true are measured.
- SR1 - Disparities of three millimetres or less as measured across the whole floor area shows your screeding to be of the finest quality and is classed as SR1.
- SR2 - The standard flooring in industrial and commercial builds is normally SR2 and has a maximum possible deviation of 5 millimetres across the whole floor.
- SR3 - SR3 is utility standard where a quality finish isn't needed. This level can have a maximum permissible deviation depth of 10 millimetres.
If your screeding has been installed with specific load bearing requirements in mind then a structural engineer will be required to carry out these soundness tests. Using specialised equipment the structural engineer will evaluate the screed surface strength and suitability of use in a load bearing setting. The screed layer should be subjected to what is known as a "drop hammer test" to measure flexibility and strength in different areas. Only fully qualified structural engineers following the British Standards BS8204 guidelines are permitted to perform such tests and sign off on the structural integrity of the screeding.

Latex Screed
When the make-up of your floor's surface means that a certain degree of flexibility is needed, it may be advantageous to apply a latex floor screed, rather than one with a more rigid finish. Latex screeds typically comprise two parts - a cementitious powder and a latex liquid mixture. The liquid latex additive takes the place of the water which is used in normal screeds, meaning that it's quicker drying and more flexible.
This latex product is used for levelling-out subfloors in advance of the laying of the final decorative surface. Appropriate for substrate of asphalt, quarry tiles, wood, sand/cement and concrete, this gives a perfect surface for the application of flooring adhesives which is also durable and smooth. Even if there is movement in your subfloor, this latex screeding will give you a flexible, crack-free finish.
When using a "floating" screed, i.e. when screeding is being laid over underfloor heating, depths of 50 to 65 millimetres may be desirable, and latex flooring screeds aren't appropriate in this instance.
Coloured Floor Screeds
The type of flooring material known as multi-coloured screeds is mostly found in commercial or industrial settings. By mixing coloured aggregates, resins, and sealers, these screeds are produced, resulting in a one-of-a-kind, 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.
To match the brand of a business or create a specific visual effect in a space, multi-coloured screeds can be customised. Facilities that demand a high level of hygiene often prefer them due to their simple cleaning and maintenance requirements. Coloured floor screeds allow architects and designers to select aggregates based on size, shape, and colour, giving them the freedom to create bespoke flooring designs tailored to their specific project parameters. All in all, coloured floor screeds provide both practicality and versatility as a flooring solution, making them a great option to add function and style to any industrial or commercial space.
Granolithic Screeding
Granolithic screeding is a process of creating a smooth and even surface for floor coverings like tiles or carpets. It involves mixing cement, sand, and aggregate such as granite or marble chips to form a mixture, which is then applied to a concrete base. The mixture is levelled with a straight edge to give it a smooth surface.
Granolithic screeding is normally used in commercial and industrial buildings as well as in high-traffic areas in residential buildings. It is also commonly used in areas where abrasion and chemical resistance are required. The resulting surface is hard and smooth, which makes it easy to clean and maintain, and provides an excellent base for other flooring products.
Granolithic screeding is typically applied over a concrete base, and the surface is generally treated with a curing compound to make sure it sets properly. As soon as it has cured, it creates a seamless floor with a hard, smooth surface that is resistant to wear. It is also resistant to water and chemicals, which makes it perfect for use in environments where there's a chance of spills or exposure to hazardous materials.
What Does Screeding Do?
Screeding plays a vital role in achieving several important objectives in construction projects:
- Corrections to Subfloors.
- Improving Thermal and Sound Insulation.
- Surface Protection.
- The Even Distribution of Loads.
- Support for Underfloor Heating Systems.
- Structural Integrity and Stability.
- Smoothing and Levelling.
- Compatibility with Floor Finishes.
Essentially, a stable, level and durable floor surface is achieved through the vital role of screeding. By ensuring a solid foundation, it supports the floor finish in maintaining its aesthetics and quality, and enduring the demands of everyday use over an extended period.
Screed Reinforcement
Screed reinforcement is a method of reinforcing concrete screeds to improve their strength and durability. To create a level surface, a base layer is coated with flat and thin layers of concrete called screeds. They're commonly used in construction projects for flooring, and can also be used as a finishing layer for ceilings and walls.
Screed mixture during installation is infused with reinforcement materials, such as wire, polypropylene fibres or steel mesh, to increase strength and prevent cracking. Reinforcement aids in the even distribution of weight and load on the surface, while also improving its resistance to thermal changes, impact and abrasion.
Factors such as finish, thickness and load capacity are taken into account when selecting reinforcement material for a project, which can vary depending on precise requirements. The even distribution of reinforcement throughout the screed and preventing displacement over time depend on its proper installation, which is essential. The quality and structural integrity of screeds can be maintained by using screed reinforcement, ensuring a long-lasting and reliable surface for various applications.
