Floor Screeding Gamlingay Cambridgeshire (SG19): If you are planning to install underfloor heating, are restoring a property or basement or have an uneven or damaged floor in your Gamlingay home, then it's a good time to think about bringing in a floor screeding professional. To provide a firm foundation for you final flooring material, a screed is used to produce a smooth floor surface over a concrete sub-base. Screeding a floor allows you to provide a durable, quality finish for any part of your home or business premises.
FLOOR SCREEDING EXPERTS GAMLINGAY
It doesn't matter how big or small the room is that you need to be levelled, a professional screeding firm in Gamlingay will have the essential skills, equipment and knowledge to provide you with an excellent level of service. When your project has been diligently evaluated, they'll be in a position to advise you on the right kind of screed your project requires, and how best it can be installed.
They'll also assess if a structural engineer is needed to make certain any point loadings, flex strength and load bearing are followed as set out in the building regulations.
A skilled and qualified work force is necessary for a successful outcome and will extend your floor's lifespan by making use of the correct kind of screed for your room's allocated purpose. A correct blend of screed and the way it is laid is also important to ensure the ultimate quality of your floor.
Before choosing a screeding company from the many operating in the Gamlingay area, ask to what standard of finish they are basing their quote, and also make sure that you get two or three quotations from different companies. The quote may be based on what is called the Surface Regularity, or SR number. SR2 and SR3 will be less costly options, although the floor screeding finish could have errors and deviations, whilst SR1 guarantees a pretty much perfect quality of finish. Any imperfections in the screeding (as might occur with SR2 or SR3) can cause issues with laying flooring because of indentations, flat spots, ridges in the floor surface.
British Standards BS8204 sets down the regulations and guidelines that all Gamlingay screeding companies is obliged to follow, and if working with specialist screeding solutions, (Gypsol, Cemfloor, Flowcrete etc), they should be approved by the manufacturers as being trained and skilled in their use. This accreditation program showcases a company's high quality performance and training in the use of a manufacturer's products.
Gamlingay commercial screeders will be involved in screeding floors in factories, boutiques, hospitals, warehouses, schools and shopping centres.
TYPES OF SCREED
Standard Screeds - A blend of sand and cement which is good for basic domestic usage. The standard screed is a mix of 5 parts sand to one of cement. After being laid a standard screed dries out at a rate of just 1mm/day.
Fibre Reinforced Screed - The first choice where under floor heating is being installed in domestic homes in Gamlingay. The special fibres in this screed mix enhance overall durability and strength whilst also protecting against thermal cracking and shrinkage. It dries at the same rate as a standard screed of 1mm per day.
Polymer Screeds - Provides a high level of strength with a minimal thickness. Due to their different chemical compositions, these polymer screeds have varying setting times which you can verify by viewing manufacturer's own product guidelines.
Self-Levelling or Liquid Screeds - Used to produce the highest quality of finish, especially in SR1 levels of screeding, by a latex and cement solution. It is mainly needed to provide a smooth, clean floor over the top of a poor quality or damaged substrate and enables all types of flooring materials to be used. These can be as little as one millimetre thick, and thanks to the latex polymers, will still provide a high strength finish.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is required, heavy duty screeds provide maximum strength and durability.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the screeded area much faster. Most of the fast or advanced drying screeds are fibre reinforced and are suitable for a wide range of flooring projects where the faster drying rate of three to seven millimetres is advantageous.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is crucial for a high quality screed surface that will be hard wearing and durable. The original floor surface should be thoroughly cleaned to remove any paint, grease, debris and oil which might adversely affect the adhesion of the screed.
Any cleaning products that are used during this stage shouldn't leave any residues, and the floor base must be permitted to dry by itself naturally. At this stage cracks should be repaired since these can travel up through the laid screed and be visible in the completed surface. During an on-site survey the screeding contractor will ascertain what preparation work is required before any actual screeding work starts.
A DPM (damp proof membrane) will be applied once the preparation work has been done to prevent ground moisture affecting the flooring materials and screed. There could be 2 or 3 layers of different thicknesses of polythene to act as barriers between the insulation layer and screed.
If the area where you live is susceptible to radon then one additional barrier is necessary to prevent the gas from entering via the ground. This could be just a simple airtight membrane, or in more serious instances a ventilation system is installed beneath the floor screed to draw out any inflow of air and gas from the ground.
Once these steps have been taken the screeders will put on a sealant or primer to the prepared floor base. A primer helps with the screed to bond to the base and different types exist based on which kind of screed is being applied. Custom-made equipment such as airless sprays can be used to apply a sealant or primer, which should be done by experienced screeding contractors in Gamlingay sticking to the manufacturer's guidelines and safety advice.
This is the time that underfloor heating can be laid out in the correct manner and installed. The heating pipes and cabling are securely attached to insulation panels to prevent any movement and make sure that they're laid in the correct position. Under floor heating is one of the most efficient ways to heat a room and an expertly installed system will deliver even warmth across the floor area.
Needless to say, if you are not fitting under floor heating, you can bypass this stage and get on with applying the screed. Your screeding specialist will give you advice on which screed type is appropriate for your requirements, in line with your intended use of the room. For advanced and quick drying screeds there will be at least a 24 hour delay before it can be walked over, and a further Three days minimum before any flooring material can be fitted. If you are using standard or heavy duty screeds the curing time is longer and the manufacturer's guidelines must be adhered to in order to get the best possible finish to your floor.
The SR level of your screed can be ascertained once it's hardened enough to be stepped onto. Using a 2m straight-edge the floor surface is checked for any deviations, dips and ridges in the screed surface.
- SR1 - SR1 is the highest quality and permits only 3mm of disparity from the straight-edge.
- SR2 - The standard flooring in industrial and commercial builds is normally SR2 and has a maximum deviation of 5mm across the entire screed.
- SR3 - For utility floors where the finish is fairly immaterial the SR3 is the standard and should have a maximum deviation measurement of 10 millimetres or less.
If you need load bearing checks, a qualified structural engineer is needed to perform the tests. This test will determine the overall strength of the screed and the suitability for its intended use. An assessment called the "drop hammer test" will be performed at several areas on the screed layer and the results recorded. Any screeding that's got point load requirements must be approved by a trained structural engineer observing the British Standards BS8204 guidelines.

Screed Reinforcement
Screed reinforcement is a method of reinforcing concrete screeds to improve their strength and durability. Applying flat, thin layers of concrete to a base layer is the method used to create level surfaces, which are called screeds. They're commonly used in building projects for flooring, and can also be used as a finishing layer for ceilings and walls.
Embedding reinforcement materials, like polypropylene fibres, wire or steel mesh, into the screed mixture during installation is done to enhance strength and prevent cracking. This reinforcement helps the surface to evenly distribute weight and load, as well as improve its ability to resist impact, abrasion and thermal changes.
The risk of shrinkage and cracking due to temperature or humidity changes is reduced by reinforcement, and this also enhances the screed's strength and durability. The proper installation of the reinforcement is crucial to guarantee even distribution throughout the screed and avoid displacement over time. The use of screed reinforcement is essential for ensuring that screeds maintain their structural integrity and quality, providing a reliable and long-lasting surface for a range of applications.
Coloured Floor Screeds
Multi-coloured floor screeds are a type of flooring material typically employed in commercial or industrial settings. The unique and decorative finish of these screeds is accomplished by mixing coloured aggregates, resins, and sealers together. They are a popular choice in areas with heavy footfall or machinery because of their slip-resistant and durable properties that allow them to withstand wear and tear.
Multi-coloured screeds provide the flexibility to match the brand of a business or achieve a desired visual effect in a space through customisation. Their easy-to-clean and maintain properties make them a favoured option for facilities that require a high level of hygiene. A seamless finish, eliminating joints or grout lines, makes coloured screeds an excellent flooring option for cleanroom environments. The freedom to select aggregates based on shape, size and colour in coloured floor screeds allows designers and architects to create custom flooring designs that are tailored to their project requirements. All in all, coloured floor screeds offer a versatile and practical flooring solution that can improve both the style and function of any industrial or commercial space.
