It matters not how big or small the area you need to be levelled, a decent floor screeding contractor in Helmshore will have the essential knowledge, skills and equipment to offer you an excellent level of service. After assessing your project they will give you advice about the perfect choice of screeding and which strategy for applying it is most appropriate for your circumstances.
They will in addition assess if a structural engineer is needed to ensure any load requirements, point loadings and flex strength are satisfied in accordance with construction and building regulations.
Working with a skilled and qualified specialist will guarantee you use the appropriate sort of screed for the room's proposed purpose to extend the lifespan of your floor. Selecting the correct screeding materials and the method of installation is crucial if you want a quality and durable finish for your floor surface.
Make certain that you get at least two or three quotes for your Helmshore floor screeding project and also ask what standard of finish each quote is for. The SR (Surface Regularity) finish is the figure to look for when studying a quotation from Helmshore floor screeding contractors. SR1 is the best standard, and whilst SR2 and SR3 may seem less expensive at first glance, they don't guarantee a perfectly flat or even floor surface. An SR2 or SR3 level could mean there are ridges or flat spots that could cause issues when putting down your final flooring surface (tile, wood, carpet etc).
The rules and regulations set out in in the British Standards BS8204 must be observed by any Helmshore floor screeding company and they must also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to confirm their safe working practices and competence. This accreditation program highlights a firm's performance and training in the use of a manufacturer's product.
Helmshore commercial screeders might be involved in the screeding of floors in schools, warehouses, shops, boutiques, hospitals and factories.
TYPES OF SCREED
Standard Screeds - This is good for everyday residential use and is a combination of cement and sand. This mix comprises a 5 to 1 ratio of sand to cement. After being laid a standard flooring screed dries out at a rate of 1mm/day.
Polymer Screeds - When a reduced thickness of floor is necessary because of construction requirements, a polymer screed provides a high strength resolution to this situation. The curing times vary as outlined by product guidelines.
Fast Drying and Advanced Drying Screeds - If you have to use the area in question ASAP a fast drying screed can be used. Drying at a rate of three to seven millimetres, determined by the mixture, they're normally a fibre reinforced kind of screed and are perfect for flooring projects which have tight deadlines.
Self-Levelling or Liquid Screeds - When the highest possible standard of finish is needed this blend of cement and latex is employed to achieve SR1 level screed flooring. This is mostly used to provide a smooth, clean floor over the top of a poor quality or damaged substrate and results in a finish onto which all kinds of flooring materials can be laid. The liquid screed can be laid to a depth of just one millimetre, but will still provide a high strength base for a varied selection of flooring materials.
Industrial and Heavy Duty Screed - Made for maximum durability and strength in areas where traffic is high or heavy loading on the floor is necessary.
Fibre Reinforced Screed - The preferred option for professional installers where under floor heating is being installed in residential homes in Helmshore. The special fibres in the screed mix improve it's durability and strength whilst also safeguarding against thermal cracking and shrinkage. It's got a setting rate of one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare all areas before any other work in order to guarantee a hard wearing and quality screed flooring. It is crucial that any contaminants such as grease, paint, debris or oil is eliminated from the floor before pouring any screed, as these can affect the adhesion capability that a good quality screed demands.
Any cleaning products which are used in this process shouldn't leave any residues, and the floor surface must be allowed to dry by itself naturally. If screeding over a cement or stone floor then all cracks should be mended to stop them from "travelling" through your screed layer and causing imperfections on the finished surface. During a site survey the screeding contractor will notice what preparations are necessary before any actual screeding starts.
Before any screeding can be poured a DPM (damp proof membrane) will have to be installed to protect the final flooring and screed from dampness. The DPM is made out of thick polythene sheet and various layers could be used to serve as a moisture barrier and air insulating layer for the screed.
If the area is susceptible to radon gas then one additional barrier is essential to prevent the gas from entering via the ground. If radon gas is present in large amounts then a complete extraction and ventilation system might be needed underneath the layer of screed which will extract any gases that are seeping in from ground level.
The final stage of surface preparation is the painting or spraying of a sealer or primer. Sealers and primers assist with the bonding process and are special applications matched to the kind of screed being used. These materials need trained tradesmen to apply them in the appropriate proportions by using airless sprays and other bespoke equipment.
Now is the time that underfloor heating can be laid out in the correct manner and installed. The under floor heating system is laid out in the correct pattern and attached firmly to insulation panels to stop potential movement during screed pouring process. Warmth is evenly spread across the floor in a skillfully installed underfloor heating system, and coupled with it being an effective method of heating, it's a good choice for the majority of Helmshore home restoration projects.
If you aren't fitting underfloor heating the screed will now be mixed and prepared on site and poured. Your screeding contractor will give you advice on which screed type is best for your requirements, in line with your intended use of the room area. After application of the screed there's a minimum 24 hours (for quick drying and advanced screeds) before you can walk on the surface, and a 72 hours minimum curing time for the laying of any floor coverings. Manufacturer's drying guidelines for heavy duty and standard screeds should be observed so as to achieve a quality finish and end up with an even and stable surface.
You can test the SR standard of the finished screeding as soon as it is hard enough for walking on. The test involves the use of a 2 mtr straight edge laid on the floor surface and any variations from true are measured.
- SR1 - SR1 is the best quality and permits just three millimetres of disparity from the straight-edge.
- SR2 - If the screeded surface deviates from the straight edge by five millimetres or less it is considered SR2 quality and is the standard for industrial and commercial projects.
- SR3 - SR3 is basic utility standard where a quality finish isn't required. This level can have a maximum permissible deviation depth of ten millimetres.
If your screeding has been laid with specific load bearing requirements in mind then a structural engineer will be needed to conduct these soundness tests. Using specialised equipment the engineer will assess the screed surface strength and suitability of use in a load bearing environment. An assessment called the "drop hammer test" will be conducted at various areas on the screed and the results noted. The specialist measurement and testing tools needed mean this can only be carried out by a fully qualified structural engineer heeding the British Standards BS8204 guidelines.

Latex Screeds Helmshore
When the nature of your floor's surface means that a bit of flexibility is necessary, it may be best to use a latex self-levelling floor screed, as opposed to one with an unyielding finish. A latex floor screed comes in two parts, a bottle and a bag, with the bag containing a cement based powder, and the bottle containing a liquid latex. The latex liquid part takes the place of the water that's used in standard screeds, meaning that it is quicker drying and more flexible.
Before the installation of your chosen decorative covering, this latex compound is used for levelling-out sub-floors. This screeding is appropriate for use on subfloors of concrete, wood, quarry tiles, asphalt and sand/cement, to provide a durable, smooth surface that's ideal for the application of adhesives. If your subfloor has a bit of movement in it, this type of floor screed will still produce a crack-free, flexible finish, onto which your final floor coverings can be laid.
Latex screeds are not suitable where a "floating" screed is desired, for instance when a screed is being laid over a layer of either acoustic or thermal insulation, such as may be the case when you're screeding over underfloor heating, and depths of 50-75mm may be needed.
