Floor Screeding Charminster Dorset (DT2): If you have an uneven or damaged floor, are restoring a property or cellar or are aiming to install underfloor heating in your Charminster home, it is a good time to think about contacting a professional floor screeder. Screeding is vital to provide you with a level and flat floor surface onto which you can lay a suitable floor covering, be it carpet, tile or wood. Floor screeding will provide a high quality and durable surface for almost any room.
FLOOR SCREEDING CONTRACTORS CHARMINSTER
It does not matter how big or small the room you need to be levelled, a decent screeding firm in Charminster will have the necessary expertise, equipment and know-how to provide you with an excellent standard of service. They'll assess the project and figure out the appropriate sort of screed you require and the best strategy for applying it.
Your screeding contractor will also notify you if a structural engineer is necessary for your project, in order to check on point loadings, load bearing and flex strength that your screed floor might need to conform with current building regulations and British Standards.
Bringing in a qualified and skilled specialist will ensure you use the right sort of screed for the room's anticipated purpose and get the maximum lifespan out of your flooring. A correct mix of screed and the techniques used for laying it are also important to guarantee the ultimate quality of your floor surface.
Make certain you get at least 2 or 3 price quotes for your Charminster based floor screeding project and also ask what standard of finish each quotation is for. The Surface Regularity (SR) finish is the figure to look for when getting a quotation from Charminster floor screeding contractors. Each of the three SR levels offer different standards of finish, with SR1 offering the best, with the lowest amount of deviation over the area. This means that you may have to rectify any areas that might cause problems when laying your final flooring material.
Every Charminster screeding company must follow British Standards (BS8204) and should have some kind of accreditation from screeding material and equipment manufacturers, e.g. Gypsol, Cemfloor, Flowcrete. The testing and training of a floor screeding company by such manufacturers is highlighted through the accreditation scheme, and gives assurances of safe working practices and reliability on any flooring project which involves their materials.
Commercial screeders in Charminster will generally undertake floor screeding projects in hospitals, factories, warehouses, restaurants, schools and shopping centres.
TYPES OF SCREED
Standard Screeds - This is perfect for everyday domestic usage and is a blend of cement and sand. 5 parts sand to 1 part cement is the usual mixture for standard flooring screeds. Once laid this 5:1 ratio will dry at a rate of one millimetre per day.
Self-Levelling or Liquid Screeds - A cement and latex formula which can produce the highest standard of finish to SR1 levels. It is mostly needed to produce a high quality floor over a damaged or poor quality substrate and enables all types of flooring materials to be used. These can be as little as 1mm thick, and thanks to the latex polymers, will still provide a high strength finish.
Polymer Screeds - Provides a high level of strength with a minimal thickness. Polymer screeds are available from a number of screed manufacturers and because of their varying chemical compositions have specific curing times for each individual product.
Fibre Reinforced Screed - Mostly used with under floor heating systems and is the recommended option in these projects. The special fibres in the screed mix improve overall durability and strength while also protecting against thermal shrinkage and cracking. It dries at the same rate as a standard screed, at about one millimetre per day.
Industrial and Heavy Duty Screed - Made for maximum durability and strength on floors where traffic is high or heavy loading on the floor base is required.
Fast Drying and Advanced 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 3-7mm, depending on the mix, they are usually a fibre reinforced type of screed and are great for projects that have tight deadlines.
SCREEDING PREPARATION AND INSTALLATION
To make certain the screeding is of a good quality finish that is hard wearing and durable, time must be devoted to preparing the area prior to any screed being poured. It's important that all contaminants such as oil, debris, paint or grease is eliminated from the base before laying any screed, since these can affect the bonding process that a good quality screed demands.
If cleansing products were used it's important to remove any residues of soap, detergent etc, and allow the floor surface to dry naturally. It is necessary to mend any cracks or crevices in the base to avoid them being mirrored and "travelling" upwards into your newly screeded floor. A decent Charminster screeding specialist will pick up on these issues during a on-site survey and ensure all preparations are finished before applying the next steps in the screeding process.
To protect the flooring materials and screeding layer from dampness rising up from the ground, a damp proof membrane (DPM) will have to be laid. There might be 2 or 3 layers of varying thicknesses of polythene to act as barriers between the screed and the insulation layer.
If the area is susceptible to radon then another barrier is essential to stop the gas from entering via the ground. An air-tight membrane may be suitable in areas with low levels of radon, but in more severe situations there may need to be a more sophisticated ventilation and extraction system to remove any harmful radon gas.
Once the base has been properly prepared and any DPMs installed, a sealer or primer is then applied. Primers and sealers assist with the bonding process and are special applications matched to the sort of screed that is being used. These substances need skilled contractors to apply them in the right proportions by using airless sprays and other custom-made equipment.
If you're installing under floor heating, this is the time that it will need to be correctly laid out and installed. The cables and heating pipes are securely attached to insulation panels to prevent any movement and make certain they are positioned correctly. When expertly installed an under floor heating system is an effective way to warm up a room and top quality screed will retain its heat, creating an even heat right across the floor surface.
If you aren't putting in under floor heating the screed can now be mixed and prepared in situ and laid. Your screeding contractor will give you advice and guidance on which screed type is best for your requirements, according to your intended use of the room. For quick drying screeds there'll be at least 24 hours delay before it is able to be walked over, and a further 72 hours minimum before you are able to lay any flooring materials. If you're looking to end up with a well finished and hard-wearing floor surface you should follow the manufacturer's guidelines with regards to standard and heavy duty screeds where the waiting period will be increased.
You can assess the SR level of the completed screeding once it's solidified enough for walking on. Using a 2 metre straight-edge the surface is checked for any dips, ridges and deviations in the screed surface.
- SR1 - Over the entire floor area, if there are no deviations of more than 3mm from the straight-edge, then you have a top quality SR1 specification surface.
- SR2 - The normal standard flooring in commercial and industrial builds is normally SR2 and has a maximum deviation of 5 millimetres across the entire screed.
- SR3 - SR3 is utility standard where a quality finish isn't necessary. This specification allows for a maximium deviation of ten millimetres.
There might also be a requirement for a structural engineer to conduct a soundness test. The testing will make sure that your newly laid screed surface is viable for the load point requirements specified in the site survey. The screed layer will be subjected to a drop hammer test to gauge flexibility and strength at specific points. Any screeding that has point load requirements must be okayed by a competent structural engineer following the British Standards BS8204 guidelines.

Latex Screeds
It may be an advantage to use a latex self-levelling floor screed when a certain amount of flexibility is needed in a floor's surface. Latex floor screeds generally comprise two parts - a cement-based smoothing compound, and a liquid latex additive. Latex screeds are quicker drying and more flexible than standard screeds, as the water that's normally used is substituted with the liquid latex.
Prior to the installation of the final decorative surface, this latex compound is used for levelling subfloors. This screed is suitable for sub-floors made of concrete, quarry tiles, wood, sand/cement or asphalt, is ideal for the application of adhesives and gives a durable, smooth surface. If your sub-floor has a bit of movement in it, this latex floor screed will still provide a flexible, crack-free finish, on which your chosen floor coverings can sit.
When an unbonded screed is being laid on top of a membrane of either thermal or acoustic insulation (i.e. a floating screed), latex screeds aren't suitable, because in such cases (typically when screeding on top of underfloor heating), you'll likely require a thickness of 50mm-75mm.
Granolithic Screeding
Granolithic screeding is an extremely popular flooring material which is used widely in heavy-duty environments because of its strength and durability. It's made from a mixture of cement, sand, aggregate, and sometimes pigments, which are combined to make a mortar-like mixture. The mixture is poured onto the floor and then smoothed out to an even, level surface.
This technique is normally used in industrial and commercial buildings, high-traffic residential areas, and spaces that require abrasion and chemical resistance. The resulting surface is easy to clean, durable, and provides the perfect base for other flooring materials.
The granolithic screeding process involves several steps, including preparation of the concrete base, blending of the screed mixture, laying of the mixture, and curing of the screed. Proper mixing, curing and application techniques are important to ensure the strength and durability of the finished surface. Moreover, the screed should be allowed to fully cure before any further flooring materials are installed on top of it.
Coloured Floor Screeds
Typically, multi-coloured screeds are the preferred flooring material for industrial or commercial settings. These screeds are made up of a combination of coloured aggregates, resins, and sealants that are mixed together to create a unique, decorative finish. Commonly, they are used in areas with heavy foot traffic or machinery due to their ability to withstand wear and tear and provide a slip-resistant surface that is long-lasting.
To match a business's branding or create a specific visual effect in a space, multi-coloured screeds can be customised. They are a popular choice for facilities that require a high standard of hygiene due to their simple cleaning and maintenance requirements. Coloured screeds are a great flooring option for cleanrooms and similar environments because they provide a seamless finish that eliminates joints or grout lines. By choosing the colour, shape and size of the aggregates used in multi-coloured floor screeds, designers and architects have the ability to create custom flooring designs that are tailored to their specific project parameters. Overall, the combination of versatility and practicality in multi-coloured floor screeds makes them a flooring solution that can enhance both style and function in any industrial or commercial space.
Screed Reinforcement
Screed reinforcement improves the durability and strength of concrete screeds by reinforcing them. Screeds are created by applying thin and flat layers of concrete to a base layer, resulting in a level surface. In building projects, they have a common use as flooring, and they can also serve as a finishing layer for walls and ceilings.
Screed mixture during installation is infused with reinforcement materials, such as wire, fibres or steel mesh, to enhance strength and prevent cracking. The reinforcement improves the surface's ability to resist thermal changes, impact and abrasion, while also ensuring that weight and load are evenly distributed.
In addition to improving the screed's durability and strength, screed reinforcement also helps to reduce the risk of cracking and shrinkage caused by changes in temperature or humidity. The correct installation of the reinforcement is crucial to guarantee uniform distribution throughout the screed and avoid displacement over time. By utilizing screed reinforcement, building professionals can guarantee that their projects will provide a functional, high-quality surface that will last for years to come.
