Floor Screeding Wolsingham County Durham (DL13): If you have a damaged or uneven floor, are hoping to install under floor heating or are restoring a property or basement, then you'll need to find a specialist service to assist you. A screed is used to produce a smooth floor surface over a concrete sub-base and give a level foundation for you final flooring material. The screed is a crucial procedure to guarantee a durable and quality finish to the entire floor structure.

Whatever shape or size of room you're renovating, a local floor screeding firm in Wolsingham can supply the expertise and proper working methods to generate a perfect base for your flooring. After assessing your project they will advise you on the perfect choice of screeding and which technique for laying it is most suited to your situation.
It might be a requirement, contingent on the intended use of the area, for a structural engineering survey to conform to building regulations on point loadings, load bearing and flex strength of the screed floor.
Working with a highly trained and qualified flooring specialist will ensure that you use the correct kind offor the room's allocated purpose to extend the lifespan of your floor. There are numerous types of screed and picking the right mix and installation technique is essential if you are to create a high quality floor which is hard-wearing and fit for purpose.
There are manycontractors in the Wolsingham area so if possible get multiple quotes for your screeding project before selecting a company and know to what standard of finish it's for. For domestic properties a quotation will usually be given for a Surface Regularity (SR) calculation of SR1 or SR2. Each of the three SR levels deliver different standards of finish, with SR1 being the highest, with the smallest amount of deviation over the surface area. This could mean that you may have to rectify any patches that may cause issues when putting down your final flooring solution.
The regulations specified in the British Standards BS8204 have to be observed by any Wolsingham floor screeding company and they should also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Gypsol, Flowcrete etc.) to prove their competence and safe working practices. The training and assessment of a floor screeding company by a manufacturer is emphasised through the accreditation scheme, and guarantees safe working practices and reliability on any screeding project which involves their materials.
For larger screeding projects in factories, warehouses, restaurants, hospitals, shops and schools, specialist commercial screeders in Wolsingham will be needed.
TYPES OF SCREED
Standard Screeds - A mix of sand and cement which is okay for standard residential use. The ratios involved are 5 parts sand to 1 part cement. The standardwill dry at a rate of 1mm thickness per day.
Liquid or Self-Levelling Screeds - Used to provide the highest quality of finish, especially where SR1 levels are needed, by a latex and cement material. Primarily used to finalise a damaged floor or poor substrate level so as to lay a new flooring surface, such as tiles on the top of it. They can be as little as 1mm in depth, and because of the latex polymers, will still provide high strength.
Advanced Drying and Fast Drying Screeds - If there's a need to use the area ASAP a fast drying screed may be used. Most of the fast or advanced drying screeds are of thekind and are appropriate for a wide variety of projects where the speedier curing rate of three to seven millimetres is advantageous.
Fibre Reinforced Screed - The expert's choice for residential use over the top of under floor heating. This is because of the increased strength and protection against thermal cracking and shrinkage provided by the fibres within the screed. The screed will set hard at a rate of roughly 1mm/day.
Polymer Screeds - These provide a high level of strength with a lower thickness. The drying times vary in accordance with proprietary product guidelines.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is necessary, heavy duty screeds offer maximum strength and durability.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish that's hard wearing and durable, time must be spent on preparing the area prior to any screed being poured. It's vital that all contaminants such as grease, paint, oil or loose debris is removed from the floor before pouring any screed, since these can affect the bonding capability that a quality floor screed needs.
Any cleaning products that are used in this process shouldn't leave any residues, and the floor base must be allowed to dry by itself naturally. At this point cracks should be mended because these can travel up through the newly laid screed and be reflected in the completed floor surface. A site survey will allow the screeding company to take note of these preparation areas and finish them before beginning to pour the screeding.
To shield the screeding layer and flooring materials from moisture rising up through the ground, a damp proof membrane (DPM) must be installed. There could be two or three layers of different thickness polythene to act as a barrier between the insulation layer and screed.
If your house is situated in an area where radon gas is present an additional barrier layer is required to prevent radon gas from entering. If radon gas is present in large amounts then a full ventilation system may be installed under the screed which will remove any gases that could seep in from ground level.
As soon as these steps have been taken the screeders will apply a sealer or primer to the prepared base surface. A primer assists in the screed bonding correctly to the base and different varieties exist based upon which screed type is being applied. Equipment such as airless sprays are used to apply a sealant or primer, which should be done by qualified screeding contractors in Wolsingham observing the manufacturer's guidelines.
If you are installing underfloor heating, now is the time that it will need to be correctly set out and installed. The wires and heating pipes are securely mounted on insulation panels to prevent any movement and make sure that they're held in the correct position. When skillfully installed an underfloor heating system is an efficient way to warm up a room and decent quality screed will retain its heat, creating an even level of warmth across the floor.
Obviously, if you're not installing under floor heating, you simply bypass this step and apply the screeding. The specific requirements of the room will dictate the kind of screeding that's used. After the pouring of the screed there'll be a minimum twenty four hours (for quick drying screeds) before you are able to walk on the surface, and a 72 hours minimum curing time for the laying of any flooring materials. Manufacturer's drying instructions for standard and heavy duty screeds should be followed so as to achieve a quality finish and end up with a stable and even surface.
The SR standard of your screeding can be confirmed once it's solidified enough to be walked upon. The test involves the use of a 2 mtr long straight-edge laid on the floor surface and any deviations from true are calculated.
- SR1 - SR1 is the best level and allows just 3 millimetres of deviation from the straight-edge.
- SR2 - If the floor has a deviation from the straight-edge of five millimetres or less it is considered SR2 quality and is the normal standard for commercial and industrial floors.
- SR3 - SR3 is basic utility standard where a quality finish is not needed. This specification allows for a maximium deviation of 10mm.
If your screeding has been laid with specific loading in mind then a structural engineer will be required to perform the assessment. Using specialist equipment the structural engineer will evaluate the screeding strength and its suitability for use in a load bearing environment. This should include what is known as a "drop hammer test" which assesses various aspects of the flexibility and strength of the screed. Any screed flooring that has point load requirements must be approved by a trained structural engineer following the British Standards BS8204 guidelines.

Improving the strength and durability of concrete screeds can be achieved by using. Level surfaces are produced by applying thin, flat layers of concrete to a base layer, known as screeds. They find common use in building projects as flooring, but they can also be utilised as a finishing layer for ceilings and walls.
The addition of reinforcement materials such as steel mesh, fibres or wire into the screed mixture during installation improves strength and helps to prevent cracking. This reinforcement improves the surface's ability to resist thermal changes, impact and abrasion, while also ensuring that weight and load are evenly distributed.
The selection of screed reinforcement material for a project is based on various factors, such as load capacity, finish and thickness, and is tailored to meet particular requirements. For a long-lasting and reliable surface suitable for various applications, the use of screed reinforcement is essential to maintain the quality and structural integrity of screeds.
