Floor Screeding Birkenhead Merseyside (CH41): A floor screeding professional can level an uneven or damaged floor, help with renovations or help to install under floor heating on your Birkenhead home, when needed. A screed is used to produce a smooth floor over a rough concrete sub-base and give a good foundation for you final flooring material. The screeding is a crucial procedure to ensure a durable and quality finish to the whole floor structure.
FLOOR SCREEDING EXPERTS BIRKENHEAD
An established screeding company in Birkenhead will have all the experience and know-how to help you achieve a perfect floor in whatever size room you are renovating. They will be ready to advise you about the right type of screed your project requires, and how best to apply and install it.
They'll likewise assess if a structural engineer is needed to make certain any point loadings, load requirements and flex strength are satisfied in accordance with construction and building regulations.
Working with a qualified and skilled flooring specialist will ensure you use the appropriate type of screed for the room's allocated purpose to extend the lifetime of your flooring. The correct mix of screed and the way it is laid is also vital to ensure the ultimate intergrity of your floor surface.
Ensure that you get at least 2 or 3 price quotes for your Birkenhead screeding project and also ask what standard of finish each price quote is for. The quotation could be based on what's known as the Surface Regularity, or SR number. Each of the 3 SR levels offer different qualities of finish, with SR1 being the highest, with the smallest amount of deviation over the area. This means you may need to correct any patches that might cause issues when laying your final flooring material.
The guidelines and regulations specified in the British Standards BS8204 must be observed by any Birkenhead floor screeding contractor and they must also be certified by the manufacturers of specialist screeding materials (Gypsol, Flowcrete, Cemfloor etc.) to confirm their competence and safe working practices. A contractor holding accreditations proves that they've been assessed and trained in using these products and can offer a top notch service in all areas of their installation.
Birkenhead commercial screeders might be involved in the screeding of floors in hospitals, hotels, schools, shops, warehouses and factories.
TYPES OF SCREED
Standard Screeds - Frequently used in domestic flooring projects where the combination of cement and sand is good for normal floor traffic usage. This mixture comprises a five to one ratio of sand to cement. Once it has been laid this 5:1 ratio dries at a rate of one millimetre each day.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is needed, heavy duty screeds allow for maximum durability and strength.
Fibre Reinforced Screed - Used with under floor heating and is the preferred choice in these projects. The increased flexibility and strength offered by the fibres in the screed mix help protect the resulting floor from thermal cracking and shrinkage. At around one millimetre per day, it has the same setting rate to standard screed.
Liquid or Self-Levelling Screeds - Used to produce the highest quality of finish, especially in SR1 levels of screeding, by a cement and latex formula. Largely used to improve a damaged floor or poor substrate level in order to lay a brand new flooring surface, like tiling over it. They can be as little as one millimetre in depth, and because of the latex polymers, will still provide a high strength finish.
Polymer Screeds - An extremely high strength solution where a reduced screed thickness is essential. The setting times for these vary as outlined by product guidelines.
Fast Drying and Advanced Drying Screeds - If there is a need to progress urgently with the work on account of time limitations, this screed dries much faster than standard flooring screeds. They're normally a fibre reinforced screed which can dry out at a rate of between three and seven millimetres per day and are employed in time-sensitive flooring projects.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is vital for a high quality screed surface that will be hard wearing and durable. It is important that all contaminants such as oil, debris, grease or paint is eradicated from the floor before laying any screed, because these can affect the bonding process that a good quality floor screed demands.
If cleansing products were used it's essential to remove any remnants of soap or detergent, and leave the floor surface to dry naturally. It is vital to repair any cracks in the floor surface to stop them being reflected and "travelling" upwards into the newly screeded floor. A reputable Birkenhead screeding company will address such issues during a on-site survey and ensure all preparations are finished before pressing on with the next steps in the floor screeding process.
A DPM (damp proof membrane) will be put down after the preparation work has been concluded to prevent ground moisture affecting the screeding and floor materials. There could be two or three layers of different thickness polythene to act as barriers between the insulation layer and screed.
If the area is susceptible to radon gas then another barrier is necessary to prevent this harmful gas from entering from the ground. This could be as simple as an air-tight membrane, or in more serious situations a ventilation and extraction system will be installed underneath the floor screed to take away any inflow of radon gas from the ground.
As soon as these steps have been taken the screeders will put on a primer or sealer to the prepared floor base. A primer assists in the screed bonding process to the base and membranes and different varieties exist according to which kind of screed is being applied. These materials need trained contractors to apply them in the right ratios by using airless sprays and other tailor-made equipment.
If required, this is the time that underfloor heating can be laid out in the correct manner and installed. The under floor heating system will be carefully positioned and attached firmly to insulation panels to prevent any movement during screed pouring process. Warmth is spread evenly across a floor area in a professionally installed underfloor heating system, and in conjunction with it being an effective method of heating, it is a great choice for the majority of Birkenhead home restoration projects.
If you are not installing underfloor heating the screed can now be prepared in situ and laid. The particular requirements of the room will dictate the kind of screeding that's used. Remember that even advanced and quick drying screeds have a minimum of 24 hours before you can walk over any screeded surface and at least 72 hours before any floor coverings can be fitted. This time period is longer for standard and heavy duty screeds and the manufacture's product guidelines should be followed to create the optimal finish and longevity of the floor.
Once the screed has set it can be quality checked to establish the SR level. The test involves using a 2m straight edge laid on the surface and any fluctuations from true are calculated.
- SR1 - Disparities of 3 millimetres or less as measured over the entire area shows your screed floor to be of the best quality and categorised as SR1.
- SR2 - The standard flooring in industrial and commercial builds is classed as SR2 and has a maximum possible deviation of 5 millimetres across the whole screeded floor.
- SR3 - For a utility area or room where the quality of finish is comparatively inconsequential SR3 is the standard and should have a maximum deviation measurement of ten millimetres or less.
If your screeding has been laid with particular loading in mind then a qualified structural engineer is going to be necessary to perform these soundness tests. Using specialised equipment the engineer will evaluate the screeded surface strength and its suitability for use in a load bearing setting. An assessment called the drop hammer test is carried out on various areas of the screed and the results noted. Only fully qualified structural engineers heeding the BS8204 guidelines are allowed to carry out these testing and sign off on the structural safety of the screeding.
