Floor Screeding Burwell Cambridgeshire (CB25): A professional floor screeding company can help install under floor heating, level an uneven or damaged floor or help with renovations on your Burwell property, when needed. Before it is possible to lay a suitable floor covering, whether it is wood, tile or carpet, the floor base needs to be as flat as possible; which is why screeding a floor is sometimes needed. A floor screed is a key component of most restoration and building projects in Burwell.
FLOOR SCREEDING COMPANIES BURWELL
Supplying the expertise and proper working practices to establish a perfect base for your flooring, a screeding company in Burwell can help you with whatever size or shape of room or area you are remodeling. To determine the right form of screed you need, and the most effective way to install it, they will do a diligent assessment of your project.
A professional screeding contractor will also let you know if a structural engineer is necessary for your project, to evaluate load requirements, point loadings and flex strength that your screed floor may require to conform with British Standards and building regulations.
The skills and training that a screeding technician brings to your project should guarantee a successful outcome and help in prolonging the lifespan of your floor or floors. The correct mixture of screed and the way it is laid is also crucial to ensure the final intergrity of your floor surface.
There are numerous screeding companies in the Burwell area so see if you can get multiple quotations for your screeding project before picking out a company and know to what standard of finish is it for. For domestic homes an estimate will normally be given for a Surface Regularity (SR) level of SR1 or SR2. SR1 is the highest level, and whilst SR2 and SR3 might be cheaper at first glance, they don't guarantee a perfectly even or flat surface. Any errors in the final screeding can cause problems in laying flooring owing to flat spots, indentations, ridges in the floor surface.
All Burwell screeding contractors have to follow British Standards (BS8204) and ought to have some kind of accreditation from screeding material and equipment manufacturers, e.g. Flowcrete, Cemfloor, Gypsol. A company holding accreditations indicates that they have been assessed and trained in the use of these screeding products and can provide a high standard of service in all areas of their installation.
For larger screeding projects in schools, shops, factories, hospitals, warehouses and hotels, skilled commercial screeders in Burwell will be needed.
TYPES OF SCREED
Standard Screeds - A blend of cement and sand which is acceptable for basic domestic usage. The standard screed is a mixture of five parts sand to one of cement. This 5:1 ratio standard screed will dry out at a rate of just one millimetre per day after laying.
Polymer Screeds - Provides an extremely high level of strength with a reduced thickness. On account of their different chemical compositions, these screeds have varying curing times which you can verify by viewing manufacturer's product guidelines.
Fast Drying and Advanced Drying Screeds - If there is a need to use the floor as soon as possible a fast drying screed can be employed. They are generally a fibre reinforced type of screed that dries out at a rate of between 3-7mm per day and are employed in time critical projects.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading of the floor is needed, heavy duty screeds provide maximum durability and strength.
Fibre Reinforced Screed - The expert's choice for domestic use over the top of under floor heating. The improved flex and strength offered by the fibres in this screed help protect the flooring from cracking and shrinkage due to heat. It dries out at the same rate as a standard screed, at about 1mm per day.
Self-Levelling or Liquid Screeds - When a high standard of finish is needed this formula of latex and cement is employed to achieve SR1 quality screed flooring. Mainly used to finalise a poor substrate level or damaged floor to enable the laying of a new flooring surface, such as tiling on the top of it. This liquid screed can be laid to a thickness of only 1mm, but will still provide a high strength base for a varied selection of flooring finishes.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is crucial for a top quality screed surface that will be durable and hard wearing. Any oil, paint, grease and debris on the original floor level can affect the bonding of the screed, and must be eradicated.
If any cleaning products were used during this stage it is important to make certain that no residues of soaps or detergents are left on the floor surface and it's permitted to dry out naturally. At this stage any cracks should be mended because these can travel up through a laid screed and be visible in the completed floor surface. An on-site survey will allow your Burwell screeding contractor to highlight these preparation areas and complete them before starting to pour the screeding.
To protect the screed layer and flooring materials from dampness rising up from the ground, a DPM (damp proof membrane) must be laid. There could be two or three layers of different thicknesses of polythene to act as a barrier between the insulation layer and screed.
If your home is situated in a place where radon is found a supplementary barrier layer is necessary to stop radon gas from getting through. This can be as simple as an air-tight membrane, or in more serious instances an extraction and ventilation system will need to be installed beneath the screeding to take away any inflow of air and gas from the ground.
The final stage of the surface preparation process is the spraying or painting of a sealant or primer. These sealers and primers will make sure the screed bonds perfectly to the floor base and help produce a high quality finished floor. These materials require qualified tradesmen to apply them in the correct ratios by using airless sprays and other custom-made equipment.
If you are going to be installing under floor heating, this is the time that it will need to be correctly set out and installed. The cables and heating pipes are firmly mounted on insulation panels to prevent any movement and make certain that they're positioned correctly. Underfloor heating is one of the most effective ways to heat a room and a properly installed system should provide even level of warmth all over the floor.
The screeding can now be mixed and prepared in situ and applied to the base. Your screeding company will give you advice and guidance on which type of screed is best for your needs, according to your intended use of the room. For quick drying and advanced screeds there will be at least twenty four hours delay before it can be walked over, and a further seventy two hours minimum before you can install any flooring materials. Manufacturer's drying guidelines for heavy duty and standard screeds should be followed in order to achieve a quality finish and provide a stable and even floor surface.
The SR standard of your screeding can be ascertained once it's set sufficiently to be walked upon. Using a 2 metre straight-edge the floor surface is examined for any ridges, deviations and dips in the screed surface.
- SR1 - Over the whole area, if there are no deviations of more than three millimetres from the straight-edge, then you have a top quality SR1 level surface.
- SR2 - The standard flooring in industrial and commercial builds is classed as SR2 and has a maximum deviation of five millimetres across the whole screeded floor.
- SR3 - If the deviation around the whole space is 10mm or less the screed quality is classed as SR3 and is suitable for utility and garage areas.
If your screed has been installed with specific load bearing requirements in mind then a qualified structural engineer is going to be required to perform the tests. This test will determine the strength of the screeded surface and its suitability for the proposed use. A "drop hammer test" will be conducted at various areas on the screed and the outcomes recorded. The specialist testing and measurement tools mean that this can only be undertaken by a competent structural engineer obeying the BS8204 guidelines.

Screed Reinforcement
Screed reinforcement improves the strength and durability of concrete screeds by reinforcing them. Screeds are thin, flat layers of concrete that are applied to a base layer to create a level surface. They are commonly used in building projects for flooring, and can also be used as a finishing layer for walls and ceilings.
The addition of reinforcement materials such as wire, polypropylene fibres or steel mesh into the screed mixture during installation improves strength and prevents cracking. The distribution of weight and load across the surface is evened out by this reinforcement, and it also enhances its ability to resist thermal changes, abrasion and impact.
The risk of cracking and shrinkage caused by temperature or humidity changes is reduced by the reinforcement process, in addition to improving the screed's strength and durability. The selection of screed reinforcement material for a project is based on various factors, such as finish, thickness and load capacity, and is tailored to meet particular requirements. The reinforcement must be installed properly to avoid displacement over time and ensure uniform distribution throughout the screed, which is crucial. Screed reinforcement is crucial for maintaining the quality and structural integrity of screeds, providing a reliable and long-lasting surface for various applications.
Granolithic Screeding
Granolithic screeding is a type of floor finishing technique which is used to provide a level and smooth surface for carpets, floor tiles or other flooring materials. It comprises a mixture of sand, cement, and aggregate (for example marble or granite chips) that is applied over a concrete base. The mixture is spread evenly over the surface and levelled using a straightedge to produce a seamless and hard-wearing finish that's durable and long-lasting.
Granolithic screeding is generally used in commercial and industrial buildings as well as in high-traffic areas in residential buildings. It is also commonly used in areas where abrasion and chemical resistance are necessary. The resulting surface is smooth and hard, which makes it easy to clean and maintain, and provides an outstanding base for other flooring materials.
The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and giving it time to cure. Appropriate application and curing techniques are essential for the longevity and strength of the screed. The screed must be fully cured before any additional flooring is installed.
