Floor Screeding Dereham Norfolk (NR19): If you have a damaged or uneven floor, are restoring a property or basement or are looking to install underfloor heating in your Dereham property, then it is the perfect time to think about bringing in a floor screeding professional. Before it is possible to lay a final floor covering, be it tile, wood or carpet, the surface of the floor should be as flat as is possible; which is why floor screeding is frequently needed. Floor screeding will provide a high quality and durable floor surface for almost any room.
FLOOR SCREEDING EXPERTS DEREHAM
It doesn't matter how big or small the room is that you need to be levelled, a trustworthy floor screeding contractor in Dereham will have the essential skills, equipment and know-how to give you a superb level of service. They will assess your project and ascertain the appropriate sort of screed you require and how best to apply it.
Your screeding company will also tell you if a structural engineer is required for your undertaking, in order to check on point loadings, flex strength and load requirements that your screed floor might need to conform with British Standards and building regulations.
A skilled and qualified work force is imperative for a successful outcome and will extend the life of your floor through the use of the right form of screed for the proposed purpose of your room. The correct mix of screed and the way it is laid is also crucial to ensure the final durability of your floor surface.
Before deciding upon a floor screeding contractor from those based in the Dereham area, ask to what standard of finish they're basing their price quote, and also ensure that you get two or three quotes from different companies. The estimate should be based on what's known as the Surface Regularity, or SR figure. Each of the 3 SR levels offer different levels of finish, with SR1 offering the highest, with the smallest amount of deviation over the area. Any error in the screeding (as might occur with SR2 or SR3) may cause problems in laying flooring owing to indentations, ridges, flat spots in the floor surface.
British Standards BS8204 lays down the guidelines and regulations that all Dereham screeding installers must follow, and if working with specialist screeding solutions, (Gypsol, Cemfloor, Flowcrete etc), they ought to be certified by the manufacturers as being skilled and trained in their use. The training and assessment of a screeding company by a manufacturer is underlined through the accreditation scheme, and gives assurances of reliability and safe working practices on any project which involves their materials.
Commercial screeders in Dereham will generally tackle screeding projects in restaurants, shops, warehouses, hospitals, schools and factories.
TYPES OF SCREED
Standard Screeds - This is ideal for standard residential usage and comprises a mix of cement and sand. The ratios involved are 5 parts sand to 1 part cement. Once laid this 5:1 ratio dries at a rate of 1mm per day.
Self-Levelling or Liquid Screeds - When a high standard of finish is required this solution of latex and cement is used to create SR1 level floor screeding. The self-levelling compound provides a smooth and clean surface over a damaged floor or rough substrate to allow all types of flooring materials to be laid. They can be as little as 1mm in depth, and because of the latex polymers, will still provide high strength.
Fast Drying and Advanced Drying Screeds - If there is a need to press ahead urgently with the work on account of time limitations, this screed dries much quicker than standard flooring screeds. Most of the fast drying screeds are fibre reinforced and are ideal for a wide array of projects where the speedier drying rate of 3-7mm/day is a considerable advantage.
Polymer Screeds - When a decreased thickness of floor is required on account of building factors, a polymer screed offers an extremely high strength solution to the problem. Maker's guidelines for curing times differ across the product ranges.
Industrial and Heavy Duty Screed - A screed that's designed for heavy traffic and high load areas where maximum durability and strength is necessary.
Fibre Reinforced Screed - The preferred option where under floor heating is being installed in domestic homes in Dereham. The special fibres in this screed improve it's durability and strength whilst also protecting against thermal cracking and shrinkage. It has a drying rate of 1mm per day.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to fully prepare the area before proceeding with any other work so as to guarantee a hard wearing and quality screed flooring. Any paint, grease, oil and debris on the existing floor level can affect the adhesion of the screed, and must be eradicated.
Any cleansing products which are used during this stage should leave no residues, and the floor base must be permitted to dry by itself naturally. At this point cracks should be mended because these can easily travel up through the newly laid screed and be visible in the completed surface. A site survey will allow the screeding company to highlight this preparation work and complete it before beginning to lay the screeding.
Before the screeding can be laid a DPM (damp proof membrane) must be put down to protect the screed and final flooring from moisture damage. Different gauges of polythene sheeting could be used as a DPM and also serve as a buffer for the screed and any insulation panels.
If the area where you live is at risk from radon then a further barrier is essential to prevent this harmful gas from entering via the ground. This can be as simple as an air-tight membrane, or in more serious situations a ventilation and extraction system is installed under the screeding to extract any influx of radon gas from the ground.
Once the floor base has been prepared and all DPMs installed, a sealant or primer is then put on. Primers help with the bonding process and are special applications specifically designed for the sort of screed that's being used. Custom-made equipment such as airless sprays can be used to apply a primer or sealant, by qualified screeding companies in Dereham sticking to the manufacturer's guidelines.
Underfloor heating can now be installed and tested before screeding is poured. The under floor heating system will be carefully positioned and secured firmly to insulation panels to avoid any movement in the course of the screed application. Under floor heating is one of the most efficient ways to heat a room and a professionally installed system should give an even warmth all over the floor.
If you're not fitting underfloor heating the screed can now be mixed and prepared in situ and poured. The requirements of the room will dictate the type of screeding used. After the pouring of the screed there's at least twenty four hours (for quick drying and advanced screeds) before you are able to walk over the surface, and a 72 hrs minimum drying time for the laying of any floor coverings. If you're aiming to wind up with a well finished and hard-wearing floor surface you should stick to the manufacturer's guidelines with regards to standard and heavy duty screeds where this time period will be increased.
The SR standard of your screeding can be confirmed once it's set enough to be stepped onto. Using a two metre straight-edge the surface is examined for any dips, ridges and deviations in the screed surface.
- SR1 - Over the whole area, if there are no deviations of more than 3 millimetres from the straight-edge, you've got a top quality SR1 specification surface.
- SR2 - If the floor deviates from the straight edge by 5mm or less it is SR2 quality and is the standard for commercial and industrial projects.
- SR3 - If the deviation is ten millimetres or less the screeding quality is classified as SR3 and is suitable for utility and garage areas.
If your screed floor has been laid with particular loading in mind then a structural engineer will be required to perform the assessment. Using specialised equipment the engineer will verify the screed strength and suitability of use in a load bearing environment. This should include a "drop hammer test" which assesses various aspects of the strength and flexibility of the screed. Any screed floor that's got load bearing requirements must be okayed by a qualified structural engineer obeying the British Standards BS8204 guidelines.
