Floor Screeding Tredegar Wales (NP22): If you are hoping to install underfloor heating, have a damaged or uneven floor or are restoring a property or basement, then you'll be needing to find a professional floor screeding service to help you. Before it is possible to lay a final floor covering, whether it is tile, carpet or wood, the surface of the floor should be as flat as possible; this is why screeding a floor is often essential. Floor screeding provides a high quality and durable surface for any room.
FLOOR SCREEDING CONTRACTORS TREDEGAR
Having all of the experience and knowledge to help you achieve a perfectly finished floor in whatever size or shape of room you are renovating, an established floor screeding company in Tredegar is the best choice for your floor screeding task. After analyzing your project they'll advise you about the optimal choice of screed and which strategy for laying it is most appropriate for your circumstances.
The screeding contractor will also notify you if a structural engineer is required for your project, to evaluate point loadings, flex strength and load bearing that your screed floor may need to conform with British Standards and building regulations.
Qualified and skilled tradesmen are imperative for a successful result and will extend the life of your floor through the use of the correct kind of screed for your room's intended purpose. Selecting the right screeding materials and the best installation technique is crucial if you want to finish up with a durable and quality finish for your floor.
Make certain you get more than one quotation for your Tredegar screeding project and also ask to what standard you are getting each quote. The quote might be based on what's called the Surface Regularity, or SR figure. SR1 is the best quality, and whilst SR2 and SR3 may seem more cost-effective at first glance, they do not guarantee a totally flat or even surface. This means you may have to rectify any patches that might cause problems when laying your final flooring material.
The regulations and guidelines laid down in the British Standards BS8204 have to be followed by all Tredegar floor screeding contractors and they must also hold accreditation with the manufacturers of specialist screeding materials (Flowcrete, Cemfloor, Gypsol etc.) to substantiate their competence and safe working practices. A company holding such accreditations demonstrates they have been assessed and trained in using these products and can offer a high standard of service in all aspects of their installation.
Commercial screeders in Tredegar will probably undertake floor screeding projects in warehouses, factories, schools, shopping centres, salons and hospitals.
TYPES OF SCREED
Standard Screeds - Used in domestic projects where the blend of sand and cement is ideal for regular floor traffic usage. The ratios involved are five parts sand to one part cement. After being laid a standard flooring screed mixture 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 offers an extremely high strength solution to the problem. The setting times vary in accordance with product guidelines.
Fibre Reinforced Screed - Used mostly with underfloor heating and is the recommended option in these projects. The special fibres in the screed mix enhance it's strength and durability whilst also safeguarding against thermal shrinkage and cracking. It dries at an identical rate to a standard screed, at about 1mm per day.
Liquid or Self-Levelling Screeds - When a high standard of finish is necessary this compound of cement and latex is employed to achieve SR1 quality floor screeding. The self-levelling compound provides a clean and level surface over a damaged floor or rough substrate to enable all flooring materials to be laid. These can be as little as one millimetre in depth, and because of the latex polymers, will still provide high strength.
Fast Drying and Advanced Drying Screeds - If there's a need to move forward urgently with the flooring on account of time constraints, these screeds dry more speedily than standard flooring screeds. Drying at a rate of three to seven millimetres, determined by the mix, they're normally a fibre reinforced kind of screed and are suitable for flooring projects which have tight schedules.
Industrial and Heavy Duty Screed - Developed for maximum durability and strength in places where traffic is expected to be high or heavy loading on the floor base is needed.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is vital for a high quality screed surface that will be hard wearing and durable. Any grease, paint, oil and debris on the original floor level can affect the adhesion of the screed, and should be eradicated.
If any products were used during this stage it's crucial to make sure that no residues of soaps, detergents or other cleaning products are left on the floor surface and it is allowed to dry out naturally. If screeding over a stone or cement floor then all cracks should be repaired to prevent them from "travelling" up through a screed layer and producing imperfections on the finished surface. A reputable Tredegar screeding company will address these aspects during a site survey and make certain all preparations are finished before pressing on with the next steps in the floor screeding process.
To protect the flooring materials and screed layer from dampness rising up from the ground, a DPM (damp proof membrane) must be laid. Different thicknesses of specialised polythene might be used as a DPM and also serve as a buffer for the screed and any insulation panels.
If the area is at risk from radon then a further barrier is essential to stop the gas from entering from the ground. A simple air-tight membrane may be enough in areas with low levels of radon, however in more severe cases there may have to be a more sophisticated ventilation and extraction system to remove any ground penetrating radon.
As soon as the base has been prepared and all membranes installed, a primer or sealer is then put on. Primers help the bonding process and are special applications according to the kind of screed that is being applied. On account of their special nature, only certified screeding specialists in Tredegar are capable of using them safely and correctly and through the use of bespoke equipment for the task.
Now is the time that under floor heating can be installed and laid out in the correct manner. Insulation panels can be laid out and the cabling and heating pipes will be securely attached to prevent any movement whilst the screed is being poured. Underfloor heating is one of the most effective ways to heat a room and a skillfully installed system will deliver even warmth in all areas of the floor.
Naturally, if you're not installing under floor heating, you simply skip this step and get on with applying the screeding. The requirements of the room will determine the kind of screeding that is used. For quick drying and advanced screeds there'll be at least twenty four hours delay before it is able to be walked on, and a further seventy two hours minimum before any flooring material can be fitted. Such timescales will be increased for heavy duty and standard screeds and the manufacture's product guidelines must be followed to the letter to produce the optimal finish and longevity of the floor.
You can evaluate the SR standard of the finished screed as soon as it is set enough to walk on. Through the use of a 2 mtr straight-edge the floor surface is checked for any dips, ridges and deviations in the surface of the screed.
- SR1 - Deviations of three millimetres or less being measured over the entire floor area shows your screeding to be of the finest quality and specified as SR1.
- SR2 - SR2 is the classification for standard commercial and industrial floors and can deviate from the straight-edge by as much as 5mm.
- SR3 - SR3 is utility standard where a perfect quality finish is not needed. This specification allows for a maximium deviation depth of 10 millimetres.
If you need to check the screed floor for load bearing, a qualified structural engineer is necessary to carry out the tests. The assessment will make sure that your new screed is suitable for the load bearing requirements specified in the original site survey. The screed layer will be subjected to a "drop hammer test" to determine flexibility and strength at different points. Only experienced structural engineers respecting the British Standards BS8204 guidelines are allowed to perform such tests and sign off on the structural safety of the screeding.

Granolithic Screeding
Granolithic screeding refers to a kind of flooring that consists of a mixture of aggregate, cement and sand. It is applied in a relatively thin layer and then smoothed to provide a durable, seamless and hard-wearing surface. It is typically used in public, commercial and industrial buildings where heavy traffic is expected.
The resulting flooring is slip-resistant, easy to clean and hard-wearing, making it ideal for use in areas with high foot traffic, such as schools, shopping centres and factories.
The granolithic screeding process involves several steps, including preparing the concrete base, mixing of the screed mixture, laying of the mixture, and curing of the screed. Proper mixing, application and curing methods are crucial to ensure the durability and strength of the final surface. In addition, the screed should be allowed to fully cure before any flooring materials are installed on top of it.
Coloured Floor Screeds
The type of flooring material known as coloured screeds is usually found in industrial or commercial settings. The unique and decorative finish of these screeds is accomplished by blending coloured resins, aggregates, and sealants together. They are commonly used in areas where there is heavy footfall or machinery, as they provide a slip-resistant and durable surface that can withstand constant wear and tear.
By customising multi-coloured screeds, a particular aesthetic can be achieved in a space or a business's branding can be matched. Facilities that demand a high standard of hygiene often select them due to their ease of maintenance and cleaning. Overall, a practical and versatile flooring solution, coloured floor screeds can add both function and style to any commercial or industrial space.
Latex Floor Screed Tredegar
When the surface of a floor needs a bit of flexibility, it may be better to use a latex floor screed. A latex floor screed comes in two parts, a bag and a bottle, with the bag containing a cement powder, and a bottle that contains a liquid latex component. The latex liquid solution actually replaces the water which would normally be used for mixing screed, and is much more flexible and quicker drying than standard screeds.
Used for levelling-out sub-floors, this latex product provides a surface for the laying of the final floor finishes. This screeding is suitable for use on subfloors of asphalt, sand/cement, concrete, quarry tiles and wood, to provide a smooth, resilient surface that is perfect for the application of flooring adhesives. Even when there happens to be a bit of movement in your sub-floor, this type of latex screeding will give you a crack-free, flexible finish.
Latex screeds aren't suitable where a "floating" screed is desired, for instance when an unbonded screed is being laid on top of a layer of either thermal or acoustic insulation, such as could be the case when you are screeding on top of underfloor heating, and screed depths of 50mm-75mm may be required.
What Does Screeindg Do?
Several essential purposes are served by screeding in construction projects:
- Compatibility with Floor Finishes.
- Smoothing and Levelling.
- Surface Protection.
- Underfloor Heating System Support.
- Improving Sound and Thermal Insulation.
- Subfloor Corrections.
- Even Load Distribution.
- Structural Integrity and Stability.
All in all, screeding is instrumental in achieving a stable, durable and level floor surface. By ensuring a solid foundation, it supports the floor finish in maintaining its quality and aesthetics, and enduring the demands of day-to-day use for years to come.
Screed Reinforcement
The method of reinforcing concrete screeds using screed reinforcement is implemented to improve their durability and strength. Screeds are created by applying thin and flat layers of concrete to a base layer, resulting in a level surface. They are commonly used in building projects for flooring, and can also be used as a finishing layer for walls and ceilings.
Reinforcement materials, such as steel mesh, polypropylene fibres or wire, are embedded within the screed mixture during the installation process to prevent cracking and increase strength. The reinforcement improves the surface's ability to resist impact, thermal changes and abrasion, while also ensuring that load and weight are evenly distributed.
The incorporation of screed reinforcement enables screeding professionals to make certain that their projects will stand the test of time and provide a functional, high-quality surface for years to come.
