Floor Screeding Crawley West Sussex (RH10): A professional floor screeder can help with renovations, help install underfloor heating or level a damaged or uneven floor on your Crawley home or business premises, when necessary. Before you can lay a suitable floor covering, be it wood, carpet or tile, the surface of the floor needs to be as flat as possible; this is why floor screeding is frequently essential. If you want 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 CRAWLEY
It doesn't matter how small or large the area is that you need levelling, a trustworthy floor screeding contractor in Crawley will have the appropriate expertise, know-how and equipment to offer you a superb standard of service. After evaluating your project they will advise you about the optimal choice of screed and which technique for laying it is most suited to your situation.
Your screeding company will also notify you if a structural engineer is needed for your undertaking, to evaluate any point loadings, flex strength and load requirements that your flooring might require to conform with current building regulations and British Standards.
The training and skills that a qualified screeding contractor brings to your project will guarantee a successful result and help to extend the life of your floors. A correct mixture of screed and the way it is laid is also vital to ensure the final intergrity of your floor.
There are many screeding companies in the Crawley area so if possible get multiple quotes for your floor screeding project before picking a contractor and know to what standard of finish it's for. The Surface Regularity (SR) finish is the number to look for when receiving a quotation from your Crawley screeding contractor. Each of the 3 SR levels deliver different qualities of finish, with SR1 being the highest quality, with the lowest amount of deviation over the area of the floor. Any imperfections in the final screeding may cause problems in laying flooring because of flat spots, indentations, ridges in the surface.
All Crawley screeding installers must observe British Standards (BS8204) and should have some kind of accreditation from the manufacturers of specialised screeding equipment and materials, e.g. Flowcrete, Gypsol, Cemfloor. A contractor holding such accreditations proves that they have been trained and assessed in the use of these screeding products and can deliver a high quality service in all aspects of their installation.
For larger screeding projects in schools, restaurants, factories, shopping centres, hospitals and warehouses, skilled commercial screeders in Crawley will be required.
TYPES OF SCREED
Standard Screeds - This is perfect for standard domestic use and is a combination of sand and cement. The ratios involved are five parts sand to one part cement. This 5 to 1 ratio standard screed will set hard at a rate of one millimetre per day after laying.
Polymer Screeds - When a lower thickness of floor is required on account of construction factors, a polymer screed offers an extremely high strength resolution to the situation. Due to their different chemical compositions, polymer screeds have varying curing times which you can verify by viewing manufacturer's product guidelines.
Industrial and Heavy Duty Screed - A screed designed for heavy traffic and high load areas where the maximum possible strength and durability is vital.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is necessary this mix of of latex and cement is employed to produce SR1 level floor screeding. This is mostly used to provide a smooth, clean floor over a damaged or poor quality substrate and results in a finish onto which all types of flooring materials can be laid. They can be as little as 1mm thick, and due to the latex polymers, will still provide a high strength finish.
Fast Drying and Advanced Drying Screeds - If you need to use the floor ASAP a fast drying screed can be utilised. Drying at a rate of 3-7mm, subject to the specialised mix, they're generally a fibre reinforced screed and are ideal for projects that have tight schedules.
Fibre Reinforced Screed - The expert's choice for domestic use on top of under floor heating. This is because of the increased durability and protection against thermal shrinkage and cracking provided by the special fibres within the screed. It sets at the same rate as a standard screed, at about 1mm per day.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is crucial for a high quality screed surface that will be durable and hard wearing. The existing floor surface should be cleaned to remove any grease, debris, paint and oil which can adversely affect the bond of the screed.
If any cleaning products were used during this stage it's crucial to make certain that no residues of soaps or detergents are left on the floor surface and it's allowed to dry out naturally. It is necessary to mend any cracks in the base to avoid them being visible and "travelling" up into your freshly screeded floor. An on-site survey will enable the screeding company to highlight this preparation work and complete it before beginning to pour the screeding.
To shield the screed layer and flooring materials from moisture rising up through the ground, a DPM (damp proof membrane) must be laid. Different thicknesses of special polythene might be used as a DPM and also act as a barrier for the screed and any insulation materials.
Another airtight barrier could be needed if your home is in a location that is known to be susceptible to radon. If radon occurs in large amounts then a full extraction and ventilation system may be installed underneath the layer of screed which will extract any gases that could seep in from ground level.
The final phase of the surface preparation process is the spraying or painting of a primer or sealer. Primers and sealers assist with the bonding process and are specialist applications according to the sort of screed being used. Custom-made equipment such as airless sprays are used to apply a primer or sealant, which should be done by qualified screeding contractors in Crawley sticking to the manufacturer's guidelines and safety advice.
Before the screeding is laid, any underfloor heating will now be installed. The underfloor heating system is laid out in the correct pattern and secured firmly to insulation panels to prevent potential movement during screed pouring. Under floor heating is one of the most effective ways to heat a room and a properly installed system will produce even warmth all over the floor.
Needless to say, if you're not putting in underfloor heating, you simply bypass this step and apply the screed. Your screeding contractor will give you guidance and advice on which screed type is best for your requirements, in line with your proposed use of the room. For advanced and quick drying screeds there'll be at least a twenty four hour delay before it is able to be walked over, and a further 3 days minimum before any flooring material can be applied. If you are laying standard or heavy duty screeds the drying time is longer and you must follow the manufacturer's guidelines in order to get the best possible finish to your floor.
The SR standard of your screed can be confirmed once it's solidified enough to be walked on. Using a two metre straight-edge the floor surface is examined for any dips, deviations and ridges in the screed surface.
- SR1 - Disparities of three millimetres or less as measured over the whole floor area shows your screed to be of the finest quality and is categorised as SR1.
- SR2 - SR2 is the classification for standard industrial and commercial floors and can deviate from the straight-edge by as much as 5mm.
- SR3 - If the deviation around the whole space is 10mm or less the quality of the screeding is specified as SR3 and is the standard required for garage and utility areas.
If you need to check the screed floor for load bearing, a qualified structural engineer is required to carry out the tests. Using specialised equipment the engineer will establish the screeding strength and viability of use in a load bearing environment. This can include what is known as a "drop hammer test" which records specific data on the flexibility and strength of the screed. Only fully qualified structural engineers obeying the British Standards BS8204 guidelines are allowed to conduct these testing and sign off on the structural integrity of screed flooring.
