If you would like your floors to last a long time then floor screeding is the most important factor in any building or renovation task.
FLOOR SCREEDING CONTRACTORS ABERTILLERY
A dependable floor screeding company in Abertillery will have all the experience and know-how to help you achieve a perfectly finished floor in whichever size room you are working on. Once your screeding project has been properly assessed, they'll be able to inform you of the right sort of screed required for your project, and how best to apply it.
A professional screeding specialist will also notify you if a structural engineer is necessary for your undertaking, to identify flex strength, point loadings and load requirements that your flooring might need to conform with current British Standards and building regulations.
A skilled and qualified work force is necessary for a successful result and will extend the life of your floor through the use of the right form of screed for the intended purpose of your room. The correct mixture of screed and the methods used for laying it are also crucial to guarantee the ultimate quality of your floor surface.
Before deciding upon a screeding specialist from the many based in the Abertillery area, ask to what standard of finish they are basing their quote, and also ensure that you get multiple price quotes. The SR (Surface Regularity) finish is the number to watch out for when receiving a quotation from Abertillery screeding companies. Each of the 3 SR levels offer different standards of finish, with SR1 offering the best, with the least amount of deviation over the surface area. This could mean that you may need to correct any areas that may cause problems when laying your finished flooring solution.
The regulations and guidelines specified in the British Standards BS8204 have to be observed by all Abertillery floor screeding companies and they must also be certified by the manufacturers of specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to demonstrate their safe working practices and competence. This accreditation program demonstrates a firm's ability and training in the use of a manufacturer's screeding merchandise.
Commercial screeders in Abertillery will generally undertake screeding projects in pubs, hospitals, factories, warehouses, schools and shops.
TYPES OF SCREED
Standard Screeds - This is ideal for standard residential usage and comprises a combination of cement and sand. The ratios involved in standard screeds are 5 parts sand to 1 part cement. The standard flooring screed will dry at a rate of 1mm thickness per day.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is necessary, heavy duty screeds offer maximum durability and strength.
Polymer Screeds - When a lower thickness of floor is necessary due to building requirements, a polymer screed provides a high strength solution to this problem. On account of their different chemical compositions, these screeds have varying curing times which you can verify by reading manufacturer's product guidelines.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially where SR1 levels are necessary, by a latex and cement compound. This is mainly needed to provide a high quality floor over a damaged or poor quality substrate and enables all types of flooring materials to be used. They can be as little as 1mm in depth, and thanks to the latex polymers, will still provide high strength.
Fast Drying and Advanced Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the floor area much sooner. Drying at a rate of 3-7mm/day, determined by the mixture, they are normally a fibre reinforced type of screed and are great for projects that have tight deadlines.
Fibre Reinforced Screed - The first choice where under floor heating is being installed in domestic properties in Abertillery. This is because of the improved durability and protection against thermal shrinkage and cracking offered by the fibres within the screed mix. It dries at an identical rate to a standard screed, at about 1mm per day.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will need to prepare the area before any other work in order to ensure a hard wearing and quality screed flooring. It is vital that all contaminants such as grease, oil, paint or loose debris is eradicated from the base before pouring any screed, since these can affect the adhesion process that a good quality screed requires.
If any products were used during this stage it's crucial to ensure that no residues of soaps or other cleaning products are left on the surface and it is allowed to dry out naturally. If screeding over a cement or stone floor any cracks should be repaired to stop them from "travelling" through your screed layer and resulting in deviations on the final floor surface. During an on-site survey your Abertillery screeding contractor will notice what preparation work is required before any actual screeding work commences.
A damp proof membrane (DPM) will be put down after the preparation work has been done to prevent ground moisture getting into the screed and floor materials. There could be two or three layers of different thicknesses of polythene to act as barriers between the insulation layer and screed.
If your home is located in a place where radon gas is found an additional barrier layer is needed to stop radon gas from getting through. An airtight membrane may be sufficient in places with low emissions of radon, but in more severe cases there may have to be a more complicated extraction and ventilation system to take away any harmful radon gases.
As soon as these steps have been taken the screeders will apply a sealant or primer to the prepared base surface. A primer assists in the screed bonding correctly to the base and different varieties exist according to which screed type is being used. On account of their special nature, only experienced screeding contractors in Abertillery are capable of using them correctly, safely and through the use of equipment which is made for this task.
If required, this is the time that under floor heating can be laid out in the correct manner and installed. The underfloor heating system will be carefully positioned and secured firmly to insulation panels to stop any movement in the course of the screed installation process. When professionally installed an underfloor heating system is an excellent way to warm a room and good quality screeding retains its heat, generating an even heat across the floor.
The screed can now be mixed and prepared in situ and spread onto the floor surface. The specific requirements of the room will determine the kind of screeding used. Don't forget that even quick drying screeds have a minimum of 24 hours before you are able to walk on any laid surfaces and at least seventy two hours before any flooring can be fitted. If you are using heavy duty or standard screeds the drying time is increased and you must observe the manufacturer's guidelines in order to get the best finish to your floor.
You can assess the SR level of the finished screed once it is set enough to walk on. Through the use of a 2 mtr straight-edge the floor surface is checked for any ridges, dips and deviations in the screed surface.
- SR1 - Over the whole area, if there aren't any deviations greater than three millimetres from the straight-edge, then you have a top quality SR1 standard surface.
- SR2 - The standard flooring in industrial and commercial builds is normally SR2 and has a maximum possible deviation of 5 millimetres across the whole screeded surface.
- SR3 - SR3 is basic utility standard where a quality finish is not required. This specification can have a maximum permissible deviation depth of ten millimetres.
If your screed floor has been installed with specific loading in mind then a qualified structural engineer will be required to carry out tests. Using specialised equipment the engineer will verify the screeded surface strength and its suitability for use in a load bearing setting. The screed layer could be given what's known as a "drop hammer test" to measure strength and flexibility at various points. The specialist measurement and testing tools mean this can only be undertaken by a fully qualified structural engineer obeying the guidelines of the British Standards BS8204.

Latex Screeding Abertillery
When a level of flexibility is needed in the surface of a floor you might find that the use of a latex self-levelling screed will be an advantage. A latex floor screed comes in 2 parts, a bottle and a bag, with the bag containing a cemetitious powder, and the bottle containing a liquid latex. The latex liquid part replaces the water which is used in standard screeds, meaning that it's quicker drying and more flexible.
This latex screed compound is used to level a subfloor before the final decorative surface is laid. This is appropriate for use on substrate of asphalt, wood, concrete, sand/cement and stone tiles, to give a resilient and smooth surface which is perfect for the application of flooring adhesives. If your sub-floor has a bit of movement in it, this type of latex screed will still give you a flexible, crack-free finish, upon which your chosen floor coverings can sit.
When installing a "floating" screed, i.e. when a screed is being laid over the top of a membrane of either thermal or acoustic insulation, thicknesses of 50 to 75 millimetres may be needed, and latex flooring screeds are not suited to this purpose.
Granolithic Screeding Abertillery
Granolithic screeding is an extremely popular flooring material that's commonly used in heavy-duty environments due to its durability and strength. It is made from a mixture of cement, aggregate, sand, and sometimes pigments, which are combined to make a mortar-like mixture. The mixture is poured onto the floor and then smoothed to a level surface.
The resulting flooring is easy to clean, slip-resistant and hard-wearing, making it ideal for use in areas with high foot traffic, such as factories, schools and shopping centres.
Granolithic screeding is typically applied over a concrete base, and the surface is typically treated with a curing compound to ensure it sets properly. Once cured, it creates a seamless floor with a hard, smooth surface that is resistant to excessive wear. It's also highly resistant to water and chemicals, which makes it ideal for use in environments where there's a chance of spills or exposure to hazardous materials.... READ MORE.
Screed Reinforcement
Screed reinforcement is employed to bolster the strength and durability of concrete screeds. Level surfaces are produced by applying thin, flat layers of concrete to a base layer, known as screeds. While commonly used in construction projects for flooring, they can also be utilised as a finishing layer for walls and ceilings.
In order to prevent cracking and improve strength, the screed mixture is enriched with reinforcement materials such as wire, steel mesh or polypropylene fibres during installation. This reinforcement helps to distribute the load and weight of the surface evenly, while also improving its resistance to abrasion, thermal changes and impact.
By decreasing the risk of cracking and shrinkage caused by changes in humidity or temperature, screed reinforcement improves both the strength and durability of screeds. Thickness, load capacity and finish are factors that influence the choice of reinforcement material for a project, which can vary depending on particular requirements. The reinforcement must be installed properly to avoid displacement over time and ensure consistent distribution throughout the screed, which is crucial. Screed reinforcement is crucial for maintaining the quality and structural integrity of screeds, providing a reliable and long-lasting surface for various applications.
