Floor Screeding Pitstone Buckinghamshire (LU7): If you have an uneven or damaged floor, are renovating a property or basement or are planning to install under floor heating, then you'll be needing to find a specialist floor screeding service to help you. To provide you with a solid base for your choice of top flooring material, a screed is used to produce a smooth floor on top of a concrete sub-base. If you would like your floors to last a long time then floor screeding is one of the most important factors in any building or renovation task.
FLOOR SCREEDING COMPANIES PITSTONE
Whatever size room or area you're renovating, a floor screeding company in Pitstone will be able to provide you with the experience and proper working methods to generate the perfect base for your floors. To determine the correct form of screed you need, and the best way to install it, they'll do a painstaking assessment of your project.
A professional screeding company will also tell you if a structural engineer is necessary for your undertaking, in order to evaluate flex strength, point loadings and load requirements that your screed floor might need to conform with current building regulations and British Standards.
A qualified and skilled work force is necessary for a successful outcome and will extend the life of your floor through the use of the right form of screed for the intended purpose of your room. Choosing the appropriate screeding materials and the best installation technique is critical if you want to end up with a quality and durable finish for your floor.
Before deciding upon a screeding specialist from any operating in the Pitstone area, ask to what standard of finish they are basing their quotation, and also make certain that you get two or three price quotes from different companies. The price quote may be based on what is called the Surface Regularity, or SR calculation. Each of the three SR levels provide different standards of finish, with SR1 being the highest, with the smallest amount of deviation over the area of the floor. Any errors or imperfections in the screeding (as might occur with SR2 or SR3) may cause issues with laying flooring due to indentations, ridges, flat spots in the floor surface.
The rules and regulations laid down in the British Standards BS8204 must be followed by all Pitstone floor screeding companies and they must also be accredited by the manufacturers of any specialist screeding materials (Flowcrete, Cemfloor, Gypsol etc.) to verify their competence and safe working practices. This accreditation scheme illustrates a contractor's ability and training in the application of a manufacturer's screeding products.
Pitstone commercial screeders might be involved in screeding floors in warehouses, hospitals, shops, factories, restaurants and schools.
TYPES OF SCREED
Standard Screeds - This is okay for everyday domestic usage and comprises a blend of sand and cement. This mix uses a 5:1 ratio of sand to cement. Once it has been laid this 5:1 ratio dries at a rate of 1mm each day.
Polymer Screeds - When a decreased thickness of floor is necessary on account of construction requirements, a polymer screed offers a high strength resolution to this problem. The curing times for these vary according to proprietary product guidelines.
Advanced Drying and Fast Drying Screeds - As the name would suggest, this screed dries rapidly and allows you to use the screeded area much faster. The vast majority of the fast or advanced drying screeds are of the fibre reinforced kind and are suitable for a whole host of projects where the quicker drying rate of 3-7mm is a considerable advantage.
Self-Levelling or Liquid Screeds - A latex and cement material which can produce the highest standard SR1 finish. It is mostly used to produce a smooth, clean floor over the top of a poor quality or damaged substrate and results in a surface onto which all forms of flooring materials can be laid. They can be as little as 1mm in depth, and due to the latex polymers, will still provide high strength.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where the maximum possible durability and strength is vital.
Fibre Reinforced Screed - The professional's choice for domestic use on top of underfloor heating. The special fibres in the screed mix improve overall durability and strength while also safeguarding against thermal cracking and shrinkage. It's got a setting rate of one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to prepare all areas before proceeding with any other work so as to ensure a high quality and hard wearing screed flooring. Any paint, grease, debris and oil on the original floor surface can affect the adhesion of the screed, and should be eliminated.
Any cleaning products used during this phase should leave no residues, and the floor surface must be permitted to dry out naturally. At this point any cracks need to be repaired because these can easily travel up through a newly laid screed and be reflected in the finished floor surface. An on-site survey will enable the screeding contractor to take note of these preparation areas and complete them before beginning to lay 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. Different gauges of polythene sheets might be used as a damp proof membrane and also serve as a buffer for the screed and any insulation material.
An additional air-tight barrier might be required if your house is in an area that's regarded as susceptible to radon gas emissions. This can be just a simple air-tight membrane, or in more serious situations an extraction and ventilation system will be installed under the screed to extract any influx of air and gas from ground level.
The final phase of surface preparation is the painting or spraying of a sealant or primer. A primer assists in the screed bonding process to the base and different types exist based upon which screed type is being applied. Owing to their specialist nature, only skilled screeding specialists in Pitstone should be entrusted with using them safely and correctly and through the use of equipment which is made for the task.
Underfloor heating can now be laid out, installed and tested before screeding is applied. The heating pipes and cabling are securely mounted on insulation panels to stop any movement and ensure that they're held in the correct position. Underfloor heating is one of the most efficient ways to heat a room and a properly installed system will provide even level of warmth in all areas of the floor.
If you aren't installing underfloor heating the screed will now be mixed and prepared on site and poured. Your proposed use of the room will help the screeding specialist on which sort of screed is ideal for your needs. For quick drying and advanced screeds there will be at least a twenty four hour delay before it can be walked on, and a further 72 hours minimum before any flooring material can be fitted. This period is longer for heavy duty and standard screeds and the manufacture's product guidelines must be followed to accomplish the optimal finish and longevity of the floor.
The SR level of your screed can be confirmed once it's solidified sufficiently to be stepped onto. The standard SR test involves the use of a two metre straight edge to check for any fluctuations in the screed surface.
- SR1 - Deviations of 3 millimetres or less being measured over the entire area shows your screed floor to be of the highest quality and classified as SR1.
- SR2 - The normal standard flooring in commercial and industrial builds is normally SR2 and has a maximum possible deviation of 5mm across the whole floor surface.
- SR3 - SR3 is basic utility standard where a perfect quality finish isn't needed. This specification can have a maximum permissible deviation of ten millimetres.
There might also be a requirement for a structural engineer to perform a soundness test. The assessment will ensure your new screeding is viable for the load point requirements laid out in the original site survey. An assessment called the drop hammer test will be performed at various areas on the screed layer and the outcomes recorded. Only certified structural engineers heeding the BS8204 guidelines are allowed to conduct these testing and sign off on the structural safety of the screeding.

What Does Screeding Do?
Within construction projects, screeding serves several critical purposes:
- Corrections to Subfloors.
- Compatibility with Floor Finishes.
- Improving Thermal and Sound Insulation.
- Even Load Distribution.
- Smoothing and Levelling.
- Underfloor Heating System Support.
- Structural Integrity and Stability.
- Surface Protection.
Essentially, the vital role of screeding is to create a durable, stable and level floor surface. By ensuring a solid foundation, it supports the floor finish in maintaining its quality and aesthetics, and enduring the demands of day-to-day use over an extended period.
Screed Reinforcement
Screed reinforcement improves the strength and durability of concrete screeds by reinforcing them. A base layer is covered with flat and thin layers of concrete, called screeds, to create a level surface. Their typical application in construction projects is as flooring, although they can also be used as a finishing layer for ceilings and walls.
To enhance strength and prevent cracking, reinforcement materials like wire, steel mesh or polypropylene fibres are included in the screed mixture during installation. The distribution of load and weight across the surface is evened out by this reinforcement, and it also enhances its ability to resist impact, thermal changes and abrasion.
By decreasing the risk of shrinkage and cracking caused by changes in temperature or humidity, the reinforcement process improves both the strength and durability of screeds. Consistent distribution throughout the screed and avoiding displacement over time are dependent on the correct installation of the reinforcement, which is essential. Screed reinforcement is a vital component in maintaining the quality and structural integrity of screeds, ensuring a reliable and long-lasting surface for many different applications.
Granolithic Screeding
Granolithic screeding is an extremely popular flooring material which is used widely in heavy-duty environments because of its durability and strength. It is made from a mixture of sand, cement, 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 a level surface.
Granolithic screeding is usually used in industrial and commercial buildings and also in high-traffic areas in residential buildings. It is also commonly used in areas where chemical and abrasion resistance are required. The resulting surface is smooth and hard, which makes it easy to maintain and clean, and provides an ideal base for other flooring materials.
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 crucial for the longevity and strength of the screed. The screed must be completely cured before any additional flooring is laid.
