FLOOR SCREEDING EXPERTS WHYTELEAFE
Providing an excellent level of service, a decent screeding company in Whyteleafe will have the essential know-how, expertise and equipment, regardless how small or large the room is that you need to be levelled. They'll be ready to advise you on the right type of screed your project requires, and the best methods for applying and installing it.
It might be necessary, depending on the intended use of the area, for a survey by a structural engineer to abide by building regulations on flex strength, load bearing and point loadings of the screed floor.
Skilled and qualified tradesmen are essential to a successful outcome and will extend the life of your floor by making use of the correct sort of screed for the intended purpose of your room. There are many different types of floor screed and picking the appropriate mix and laying method is essential to create a quality floor that is both fit for purpose and hard-wearing.
There are a number of screeding specialists in the Whyteleafe area so if possible get multiple quotes for your screeding project before choosing a contractor and know to what standard of finish it's for. The quotation should be based on what's known as the SR, or Surface Regularity number. SR2 and SR3 will be less expensive options, however the floor screeding finish may have errors and deviations, whilst SR1 guarantees a pretty much perfect quality of finish. An SR2 or SR3 standard might mean there will be ridges or flat spots that could cause problems when laying your final flooring surface (tile, carpet, wood etc).
The regulations specified in the British Standards BS8204 must be followed by all Whyteleafe floor screeding companies and they should also be approved by the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to prove their safe working practices and competence. A contractor holding such accreditations shows that they have been trained and assessed in using these products and can deliver a top notch service in all aspects of their installation.
Commercial screeders in Whyteleafe will generally undertake larger screeding projects in warehouses, shopping centres, restaurants, schools, factories and hospitals.
TYPES OF SCREED
Standard Screeds - A mix of cement and sand which is ideal for regular residential use. Five parts sand to one part cement is the typical mixture for standard screeds. Once it has been laid this 5:1 ratio dries at a rate of one millimetre each day.
Polymer Screeds - An extremely high strength solution where a reduced thickness is essential. On account of their different chemical compositions, polymer screeds have varying curing times which you can verify by checking manufacturer's guidelines.
Self-Levelling or Liquid Screeds - Used to provide the highest quality of finish, especially in SR1 levels of screeding, by a latex and cement mixture. The self-levelling compound provides a clean and smooth surface over a rough substrate or damaged floor to enable all types of flooring materials to be laid. This liquid screed can be laid to a depth of just 1mm, but will still provide a high strength base to take a selection of flooring finishes.
Industrial and Heavy Duty Screed - A screed designed for heavy traffic and high load areas where the maximum possible strength and durability is necessary.
Advanced Drying and Fast Drying Screeds - If there's a need to use the floor as soon as possible a fast drying screed can be employed. The majority of the fast drying screeds are fibre reinforced and are ideal for a wide array of projects where the quicker drying rate of three to seven millimetres is an advantage.
Fibre Reinforced Screed - The professional's choice for domestic use over the top of underfloor heating. The improved flexibility and strength offered by the special fibres within the screed mix help protect the resulting floor from cracking and shrinkage due to heat. The screed will set hard at a rate of 1mm/day.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to prepare the area before any other work in order to ensure a high quality and hard wearing screed flooring. It is crucial that all contaminants such as oil, loose debris, grease or paint is removed from the floor surface before laying any screed, because these can affect the adhesion process that a good quality screed demands.
Any cleansing products which are used in this stage should leave no residues, and the floor surface must be permitted to dry out naturally. It is essential to repair any cracks in the floor surface to stop them being visible and "travelling" upwards into your freshly screeded floor. During an on-site survey the screeding company will ascertain what preparation work is needed before any actual screeding work begins.
Before the screeding can be poured a damp proof membrane (DPM) must be put down to protect the screed and final flooring from moisture. There could be two or three layers of different thickness polythene to act as a barrier between the insulation layer and screed.
An additional airtight barrier could be needed if your home is in a location which is known to be susceptible to radon gas. If radon occurs in severe doses then a complete extraction and ventilation system may be installed underneath the screed which will extract any gases that could seep in from ground level.
Once the base has been prepared and any membranes installed, a primer or sealant is then put on. A primer assists in the screed to bond to the base and different types exist according to which type of screed is being used. These products need skilled tradesmen to apply them in the right proportions by using airless sprays and other bespoke equipment.
If you are installing under floor heating, now is the time that it will need to be laid out and installed. The underfloor heating system is laid out in the correct pattern and secured firmly to insulation panels to stop potential movement in the course of the screed pouring process. When professionally installed an underfloor heating system is an efficient way to warm up a room and good quality screed will retain its heat, generating an even level of warmth across the floor surface.
The screed can now be prepared in situ and poured onto the floor base. Your use of the room will assist your screeding specialist on what form of floor screed is perfect for your requirements. For quick drying screeds there'll be at least a 24 hour delay before it is able to be walked on, and a further Three days minimum before you are able to install any flooring materials. Manufacturer's drying instructions for heavy duty and standard screeds must be observed so as to achieve a quality finish and end up with an even and stable surface.
Once the screed has solidified it can be quality checked to verify the SR level. The standard SR test uses a 2 mtr straight edge to check for any variations in the screeded surface.
- SR1 - Over the entire screed area, if there aren't any deviations of more than 3mm from the straight-edge, then you have a top quality SR1 standard surface.
- SR2 - SR2 is the classification for normal standard floors in commercial and industrial projects and can deviate from the straight-edge by up to 5 millimetres.
- SR3 - For a utility area or room where the quality of finish is fairly inconsequential the SR3 is the standard and should have a maximum deviation measurement of 10 millimetres or less.
If your screeding has been laid with specific loading in mind then a structural engineer will be required to carry out the tests. The testing will make certain that your newly laid screeding is suitable for the load bearing requirements specified in the original site survey. This should include a drop hammer test which records specific data on the strength and flexibility of the screed. The precise testing and measurement tools mean this can only be carried out by a competent structural engineer obeying the guidelines of the British Standards BS8204.

Granolithic Screeding Whyteleafe
Granolithic screeding is a kind of floor finishing technique which is used to provide a level and smooth surface for floor tiles, carpets or other flooring products. It's a mixture of sand, cement, and aggregate (for instance marble or granite chips) that is applied over a concrete base. The mixture is evenly spread over the surface and levelled using a straight edge to produce a smooth and hard-wearing finish which is long-lasting and durable.
This technique is normally used in commercial and industrial 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 products.
The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and allowing it to cure. Correct application and curing techniques are vital for the strength and longevity of the screed. The screed must be fully cured before any further flooring products are installed.... READ MORE.
