Floor Screeding Abingdon Oxfordshire (OX14): When embarking on the renovation of a property or basement, addressing a damaged or uneven floor, or considering underfloor heating installation in your Abingdon home, it is imperative to rely on the expertise of a floor screeding contractor. The objective of screeding is to create a level and uninterrupted surface atop a concrete sub-base, offering a robust foundation for your favoured flooring material. This indispensable procedure ensures a resilient and top-notch finish for the complete floor structure, securing its longevity and durability. By seeking the assistance of a floor screeding specialist, you can be certain of achieving a faultless and durable floor surface that caters precisely to your exact requirements.
FLOOR SCREEDING CONTRACTORS ABINGDON
Whatever size room or area you are renovating, a decent floor screeding firm in Abingdon can provide you with the expertise and proper working practices to establish a perfect base for your floors. After assessing your project they'll give you advice on the perfect choice of screed and which technique for applying it is most suited to your circumstances.
It may be necessary, based on the intended use of the area in question, for a survey by a structural engineer to conform to building regulations on point loadings, flex strength and load requirements of the screed floor.
A skilled and qualified work force is imperative for a successful outcome and will extend the lifespan of your floor through the use of the right kind of screed for your room's intended purpose. There are numerous types of screeding and selecting the correct mix and laying technique is crucial to create a top quality floor which is fit for purpose and durable.
Make certain you get more than one quotation for your Abingdon floor screeding project and also ask what standard of finish each quotation is for. The SR (Surface Regularity) finish is the number to watch out for when getting a quote from your Abingdon screeding contractor. SR1 is the highest standard, and while SR2 and SR3 may be more cost-effective initially, they don't guarantee a perfectly even or flat surface. An SR2 or SR3 level could mean there will be flat spots or ridges that might cause issues when installing your final flooring materials.
British Standards BS8204 lays down the guidelines and regulations that all Abingdon screeding contractors are required to follow, and if using specialist screeding solutions, (Gypsol, Cemfloor, Flowcrete etc), they must be accredited by the manufacturers as being trained and skilled in their use. This accreditation program showcases a firm's training and ability in the application of a manufacturer's products.
Commercial screeders in Abingdon will usually undertake larger screeding projects in factories, restaurants, warehouses, shopping centres, schools and hospitals.
TYPES OF SCREED
Standard Screeds - This is good for regular domestic usage and comprises a mixture of sand and cement. The ratios involved are 5 parts sand to 1 part cement. Once it has been laid this 5:1 ratio dries at a rate of 1mm each day.
Liquid or Self-Levelling Screeds - A cement and latex formula which can achieve the highest standard of finish to SR1 levels. Primarily used to improve a damaged floor or poor substrate level to enable the laying of a brand new flooring surface, such as tiles over the top of it. These can be as little as 1mm thick, and thanks to the latex polymers, will still provide a high strength finish.
Fast Drying and Advanced Drying Screeds - If you need to press ahead urgently with the work due to time constraints, these screeds dry much quicker than standard flooring screeds. Most of the fast or advanced drying screeds are of the fibre reinforced kind and are perfect for a wide variety of projects where the quicker curing rate of 3-7mm is advantageous.
Fibre Reinforced Screed - The favoured option where underfloor heating is being installed in residential homes in Abingdon. The greater flex and strength offered by the special fibres in this screed help protect the resulting floor from shrinkage and cracking due to heat. It sets at an identical rate to a standard screed of 1mm per day.
Industrial and Heavy Duty Screed - A screed that's designed for high load and heavy traffic areas where the maximum possible strength and durability is essential.
Polymer Screeds - Provides a high level of strength with a reduced thickness. On account of their different chemical compositions, these have varying curing times which you can verify by reading manufacturer's guidelines.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is essential for a high quality screed surface that will be hard wearing and durable. It is vital that any contaminants such as loose debris, oil, grease or paint is removed from the floor surface before pouring any screed, because these can affect the adhesion process that a good quality screed demands.
If any products were used during this stage it is crucial to make sure that no residues of soaps or other cleaning products are left on the floor surface and it's allowed to dry out naturally. At this stage cracks should be mended since these can easily travel up through the newly laid screed and be reflected in the finished floor surface. A skilled Abingdon screeding company will pick up on these issues during the site survey and ensure all preparations are finished before moving on to the next steps in the screeding process.
To shield the flooring materials and screed layer from moisture rising up from the ground, a damp proof membrane (DPM) must be laid. There might be 2 or 3 layers of different thicknesses of polythene to act as barriers between the screed and the insulation layer.
If the area where you live is at risk from radon gas then an additional barrier is required to prevent the gas from entering from the ground. A simple air-tight membrane may be suitable in areas with low emissions of radon, but in more severe situations there may need to be a more complicated ventilation and extraction system to block any harmful radon gases.
Once the base has been properly prepared and any DPMs installed, a sealer or primer is then applied. A primer assists in the screed bonding process to the base surface and different varieties exist based on which screed type is being used. On account of their specialist nature, only trained screeding contractors in Abingdon should be entrusted with using them correctly, safely and through the use of bespoke equipment for the task.
If required, this is the time that under floor heating can be laid out in the correct manner and installed. Insulation panels can be laid out and the cabling and heating pipes will be firmly attached to prevent any movement while the screed is poured. Warmth will be evenly spread across a floor area 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 Abingdon renovation projects.
If you're not installing under floor heating the screed will now be mixed and prepared on site and poured. Your proposed use of the room will help your screeding specialist on which sort of floor screed is perfect for your needs. For quick drying screeds there'll be at least twenty four hours delay before it is able to be walked on, and a further 3 days minimum before you can install any flooring materials. If you are looking to end up with a properly finished and long-lasting floor surface you should follow the manufacturer's guidelines with regards to heavy duty and standard screeds where this time period will be longer.
You can test the SR standard of the finished screeding once it is hard enough to walk on. The basic SR test uses a 2 mtr long straight-edge to check for any variations in the screed surface.
- SR1 - SR1 is the best standard and allows just three millimetres of deviation from the straight-edge.
- SR2 - If the screeded surface deviates from the straight edge by 5 millimetres or less it is classified as SR2 quality and is the standard for industrial and commercial floors.
- SR3 - SR3 is basic utility standard where a quality finish is not required. This level can have a maximum permissible deviation of ten millimetres.
If you need to check the screed floor for load bearing, a structural engineer is required to conduct the testing. Using specialised equipment the engineer will ascertain the screeding strength and its suitability for use in a load bearing setting. The screeding will be subjected to what is known as a drop hammer test to measure strength and flexibility in specific areas. Only trained structural engineers applying the BS8204 guidelines are allowed to carry out such testing and sign off on the structural safety of screed flooring.

Screed Reinforcement
The application of screed reinforcement is a means of enhancing the durability and strength of concrete screeds. To create a level surface, a base layer is coated with thin and flat layers of concrete called screeds. They're commonly used in building projects for flooring, and can also be used as a finishing layer for ceilings and walls.
Reinforcement materials, such as fibres, steel mesh or wire, are embedded within the screed mixture during the installation process to enhance strength and prevent cracking. The reinforcement improves the surface's ability to resist thermal changes, abrasion and impact, while also ensuring that load and weight are evenly distributed.
The risk of cracking and shrinkage caused by humidity or temperature changes is reduced by screed reinforcement, in addition to improving the screed's durability and strength. The selection of reinforcement material for a project is based on various factors, such as thickness, load capacity and finish, and is tailored to meet particular requirements. To maintain the structural integrity and quality of screeds, it is essential to use screed reinforcement, resulting in a reliable and long-lasting surface for many different applications.
