Floor Screeding Walsall West Midlands (WS1): A professional floor screeding company can assist with renovations, level an uneven or damaged floor or help install underfloor heating on your Walsall home, when necessary. A screed is used to create a smooth floor on top of a concrete sub-base and provide a level foundation for your choice of top flooring material. The screed is a vital process to guarantee a high quality and durable finish to the entire floor surface.
FLOOR SCREEDING CONTRACTORS WALSALL
It doesn't matter how small or large the room you need levelling, an established floor screeding contractor in Walsall will have the essential equipment, know-how and skills to give you an outstanding level of service. They'll assess the project and figure out the correct type of screed you need and the best strategy for applying it.
They will additionally assess if a structural engineer is needed to ensure any point loadings, load bearing and flex strength are satisfied as outlined by building and construction regulations.
The skills and training that a certified screeding specialist brings to your project will guarantee a successful outcome and help in prolonging the lifetime of your floors. A correct mix of screed and the way it is laid is also critical to ensure the final intergrity of your floor surface.
Make sure you get at least 2 or 3 price quotes for your Walsall screeding project and also ask what standard of finish each quote is for. The quotation may be based on what's called the SR, or Surface Regularity number. Each of the 3 SR levels offer different qualities of finish, with SR1 offering the best, with the lowest amount of deviation over the surface area. Any errors in the screeding (as might arise with SR2 or SR3) may cause issues with laying flooring owing to ridges, flat spots, indentations in the floor surface.
The guidelines and regulations laid down in the British Standards BS8204 have to be observed by any Walsall floor screeding company and they should also be approved by the manufacturers of any specialist screeding materials (Flowcrete, Gypsol, Cemfloor etc.) to demonstrate their safe working practices and competence. This accreditation scheme showcases a firm's training and performance in the application of a manufacturer's merchandise.
Commercial screeders in Walsall will usually undertake larger screeding projects in pubs, factories, warehouses, schools, shopping centres and hospitals.
TYPES OF SCREED
Standard Screeds - A mix of cement and sand which is acceptable for basic residential use. The ratios involved in standard screeds are 5 parts sand to 1 part cement. Once it has been laid this 5:1 ratio dries at a rate of one millimetre each day.
Polymer Screeds - A high strength flooring solution where a reduced screed thickness is needed. The drying times vary in accordance with proprietary product guidelines.
Industrial and Heavy Duty Screed - A screed that is designed for heavy traffic and high load areas where the maximum possible strength and durability is very important.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is needed this mixture of latex and cement is used to achieve SR1 quality screed flooring. This self-levelling compound provides a smooth and level surface over a damaged floor or rough substrate to allow all flooring materials to be laid. Even with a thickness of only 1mm, the latex polymers within the screed provide a high strength surface for a wide range of uses.
Fast Drying and Advanced Drying Screeds - If you need to press ahead urgently with the work owing to time limitations, these screeds dry more speedily than standard flooring screeds. These are normally a fibre reinforced screed that dries out at a rate of between three and seven millimetres per day and are employed in time-sensitive projects.
Fibre Reinforced Screed - Used mostly with under floor heating systems and is the advised option in such projects. The increased flex and strength provided by the special fibres within this screed mix help protect the resulting floor from thermal shrinkage and cracking. It's got a drying rate of one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will have to fully prepare the area before proceeding with any other work so as to guarantee a high quality and hard wearing screed flooring. The existing floor surfaces should be cleaned to remove any paint, debris, oil and grease which can affect the bond of the screed.
If cleaning products have been used it's important to remove any remnants of detergent or soap, and leave the surface to dry naturally. It's vital to fix any crevices or cracks in the floor surface to avoid them being reflected and "travelling" up into your newly screeded floor. During a site survey your Walsall screeding specialist will notice what preparation work is required before starting to work on the actual screeding.
Before any screeding can be poured a DPM (damp proof membrane) will have to be installed to shield the final flooring and screed from moisture. There might be 2 or 3 layers of different thicknesses of polythene to act as a barrier between the screed and the insulation layer.
If the area where you live is susceptible to radon gas then one additional barrier is necessary to prevent the gas from entering via the ground. If radon occurs in severe doses then a full ventilation and extraction system may be installed underneath the screed which will remove any gases that could seep in from ground level.
The final step of the surface preparation process is the spraying or painting of a sealer or primer. A primer assists in the screed to successfully bond to the base and membranes and different varieties exist according to which screed type is being applied. Equipment such as airless sprays are used to apply a primer or sealant, by professional screeding contractors in Walsall following the manufacturer's guidelines.
This is the time that underfloor heating can be installed and laid out in the correct way. The heating pipes and cabling are firmly mounted on insulation panels to prevent any movement and make sure they are held in the correct position. When professionally installed an underfloor heating system is an effective way to warm up a room and high quality screed will retain its heat, producing an even level of warmth right across the floor.
Naturally, if you're not putting in underfloor heating, you can ignore this step and apply the screeding. Your screeding contractor will give you advice and guidance on which type of screed is best for your requirements, according to your intended use of the room area. For advanced and quick drying screeds there will be at least 24 hours delay before it can be walked on, and a further 3 days minimum before any flooring material can be fitted. If you are aiming to wind up with a nicely finished and long-lasting floor surface you must stick to the manufacturer's guidelines with regards to heavy duty and standard screeds where this waiting period will be increased.
As soon as the screeding has set it can be checked for quality to determine the SR standard. The test involves using a 2 metre straight edge laid down upon the floor surface and any fluctuations from true are measured.
- SR1 - Disparities of three millimetres or less being measured across the entire area shows your screed floor to be of the highest quality and is classified as SR1.
- SR2 - The normal standard flooring in commercial and industrial builds is normally SR2 and has a maximum deviation of five millimetres across the entire screeded surface.
- SR3 - If the deviation around the room is 10 millimetres or less the screed quality is categorised as SR3 and is suitable for utility and garage areas.
If your screed floor has been laid with particular loading in mind then a qualified structural engineer will be necessary to conduct tests. Using specialised equipment the structural engineer will ascertain the screeding strength and viability of use in a load bearing environment. This can include a "drop hammer test" which records specific data on the flexibility and strength of the screed. Only certified structural engineers applying the British Standards BS8204 guidelines are allowed to conduct such testing and sign off on the structural safety of the screeding.
