FLOOR SCREEDING EXPERTS BRIXTON
Having all of the know-how and experience to help you achieve a perfect floor in whichever size room you're renovating, a professional floor screeding company in Brixton is the ideal choice for your floor screeding project. They will be able to assess your project and ascertain the correct sort of screed you require and how best to apply it.
It may be a requirement, according to the proposed use of the area in question, for a survey by a structural engineer to abide by building regulations on flex strength, point loadings and load requirements of the screed floor.
Skilled and qualified workers are necessary for a successful outcome and will extend your floor's lifespan by using the right type of screed for your room's anticipated purpose. There are many different kinds of screeding and selecting the appropriate mix and installation technique is essential to create a quality floor that is both fit for purpose and long-lasting.
There are numerous screeding companies in the Brixton area so if possible get multiple quotations for your project before picking a contractor and know to what standard of finish it's for. The Surface Regularity (SR) finish is the number to watch out for when receiving a quotation from your Brixton screeding contractor. SR2 and SR3 may be less expensive options, however the finished floor surface may have errors and deviations, whilst SR1 guarantees a pretty much perfect finish. An SR2 or SR3 level may mean there will be flat spots or ridges that might cause problems when laying your final flooring materials.
All Brixton screeding companies have to observe British Standards (BS8204) and should have some kind of accreditation from screeding material and equipment manufacturers, for instance Cemfloor, Flowcrete, Gypsol. The training and assessment of a screeding company by a manufacturer is highlighted through the accreditation scheme, and guarantees safe working practices and reliability on any flooring project which involves their materials.
For larger floor screeding projects in schools, warehouses, shopping centres, restaurants, factories and hospitals, dedicated commercial screeders in Brixton will be required.
TYPES OF SCREED
Standard Screeds - Used in domestic projects where the mix of sand and cement is perfectly acceptable for basic footfall usage. Five parts sand to one part cement is the normal mixture for standard flooring screeds. This 5 to 1 ratio standard flooring screed will dry out at a rate of 1mm per day after application.
Fast Drying and Advanced Drying Screeds - If there is a need to use the area as quickly as possible a fast drying screed can be employed. The vast majority of the fast or advanced drying screeds are fibre reinforced and are appropriate for a wide array of flooring projects where the speedier drying rate of 3-7mm is advantageous.
Polymer Screeds - An extremely high strength flooring solution where a reduced screed thickness is needed. The setting times for these vary in accordance with product guidelines.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is required, heavy duty screeds deliver maximum durability and strength.
Fibre Reinforced Screed - Used mostly with under floor heating systems and is the preferred choice in such projects. The greater flex and strength provided by the fibres in this screed mix help protect the resulting floor from shrinkage and cracking due to heat. The screed will set hard at a rate of roughly 1mm/day.
Liquid or Self-Levelling Screeds - A cement and latex formula which can achieve the highest standard SR1 finish. The self-levelling compound provides a clean and level surface over a damaged floor or rough substrate to allow all flooring materials to be laid. These can be as little as 1mm thick, and due to the latex polymers, will still provide high strength.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare the area before any other work in order to guarantee a hard wearing and quality screed flooring. It's important that any contaminants such as paint, grease, oil or debris is removed from the base before pouring any screed, because these can affect the adhesion capability that a good quality screed demands.
If any cleaning products are used in this process it is vital to make sure that no residues of soaps, detergents or other cleaning products are left on the floor surface and it is allowed to dry out naturally. If screeding over a cement or stone floor all cracks should be mended to prevent them from "travelling" through your screed layer and causing deviations on the final surface. During an on-site survey your Brixton screeding specialist will be able to see what preparation work is needed before any actual screeding commences.
A DPM (damp proof membrane) will be installed after the preparation work has been finished to stop ground dampness getting into the flooring materials and screed. Different gauges of polythene sheeting may be used as a damp proof membrane and also serve as a barrier for the screed and any insulation panels.
If your property is situated in an area where radon gas is present an extra barrier layer is necessary to prevent radon gas from getting through. This can be as simple as an airtight membrane, or in more serious cases a ventilation system will need to be installed under the floor screed to take away any influx of air and gas from ground level.
The final stage of surface preparation is the painting or spraying of a sealer or primer. These primers and sealers will make sure the screed bonds effectively to the base and help create a good quality finished floor. Because of their specialist nature, only experienced screeding contractors in Brixton should be entrusted with using them correctly, safely and using equipment which is made for this task.
Now is the time that underfloor heating can be installed and laid out in the correct way. The wires and heating pipes are firmly mounted on insulation panels to stop any movement and ensure they are held in the correct position. When properly installed an underfloor heating system is an efficient way to warm up a room and high quality screeding will retain its heat, producing an even level of warmth across the floor.
If you aren't putting in under floor heating the screed will now be prepared on site and laid. The requirements of the room will determine the type of screeding that's used. Remember that even quick drying screeds have a minimum of 24 hours before you are able to walk on any screeded surfaces and at least 72 hours before any flooring materials can be laid. Manufacturer's drying guidelines for heavy duty and standard screeds should be observed so as to achieve a quality finish and end up with a stable and long lasting surface.
As soon as the screeding has hardened it can be quality checked to confirm the SR standard. The test involves using a 2 mtr straight edge laid down upon the floor surface and any variations from true are calculated.
- SR1 - Deviations of three millimetres or less being measured across the whole floor area shows your screeding to be of the highest quality and classed as SR1.
- SR2 - The standard flooring in commercial and industrial builds is classed as SR2 and has a maximum possible deviation of five millimetres across the whole floor surface.
- SR3 - For a utility area or room where the quality of finish is relatively unimportant the SR3 is the standard and has a maximum deviation measurement of ten millimetres or less.
If your screed has been installed with particular loading in mind then a qualified structural engineer is going to be necessary to conduct tests. This assessment will ascertain the strength of the screeded surface and the viability for its intended use. The screeding will be subjected to a "drop hammer test" to determine flexibility and strength in specific areas. The precise measurement and testing tools required mean that this can only be conducted by a qualified structural engineer following the guidelines of BS8204.

Coloured Floor Screeds
A flooring material widely used in industrial or commercial settings is multi-coloured floor screeds. The unique and decorative finish of these screeds is accomplished by blending coloured resins, aggregates, and sealants together. They are commonly used in areas where there is machinery or heavy footfall, as they provide a slip-resistant and durable surface that can withstand continuous wear and tear.
By customising multi-coloured screeds, a particular aesthetic can be achieved in a space or a business's branding can be matched. They are a popular choice for facilities that require a high level of hygiene due to their simple cleaning and maintenance requirements. Overall, coloured screeds are a practical and versatile flooring solution that can add both function and style to any commercial or industrial space.
Screed Reinforcement
Screed reinforcement is a technique for reinforcing concrete screeds to improve their strength and durability. Screeds are thin, flat layers of concrete that are applied to a base layer to create a level surface. They're commonly used in building projects for flooring, and can also be used as a finishing layer for walls and ceilings.
Screed mixture during installation is infused with reinforcement materials, such as wire, steel mesh or polypropylene fibres, to prevent cracking and improve strength. This reinforcement improves the surface's ability to resist thermal changes, abrasion and impact, while also ensuring that weight and load are evenly distributed.
The risk of shrinkage and cracking caused by humidity or temperature changes is reduced by reinforcement, in addition to improving the screed's strength and durability. Screed reinforcement is a vital component in maintaining the structural integrity and quality of screeds, ensuring a reliable and long-lasting surface for a range of applications.
Latex Screeds
It is advantageous to use a latex self-levelling screed when a certain amount of flexibility is needed in a floor's surface. Latex screeds typically comprise 2 parts - a cementitious powder and a liquid latex additive. The liquid latex solution replaces the water which would typically be used for mixing screed, and is much more flexible and quicker drying than standard screeds.
This latex screed is used to level a sub-floor prior to the final decorative surface being installed. This is appropriate for use on substrate of stone tiles, asphalt, wood, concrete and sand/cement, to give a smooth, durable surface that is ideal for the application of flooring adhesives. If there's any movement in the sub-floor this type of screeding will provide a crack-free, flexible finish on which you can lay your chosen floor coverings.
When using a "floating" screed, i.e. when a screed is being laid over a membrane of either acoustic or thermal insulation, thicknesses of 50 to 65 millimetres may be required, and latex floor screeds are not suited to this purpose.
Granolithic Screeding
Granolithic screeding is a kind of floor finishing technique used to provide a level and smooth surface for floor tiles, carpets or other flooring materials. It comprises a mixture of cement, sand, and aggregate (such as marble or granite chips) that is applied over a concrete base. The mixture is evenly spread over the surface and levelled using a straightedge to produce a smooth and hard-wearing finish that's long-lasting and durable.
The resulting flooring is easy to clean, slip-resistant and hard-wearing, making it ideal for use in areas with high foot traffic, such as shopping centres, factories and schools.
The granolithic screeding process involves preparation of the concrete base, mixing the screed mixture, laying the mixture, and allowing it to cure. Appropriate application and curing techniques are vital for the longevity and strength of the screed. The screed must be completely cured before any additional flooring materials are installed.
