To ascertain the correct sort of screed you need, and the most effective way to apply it, they will do a proper evaluation of your project.
A professional screeding company will also let you know if a structural engineer is needed for your project, in order to check on load requirements, point loadings and flex strength that your screed floor may require to conform with current building regulations and British Standards.
Bringing in a skilled and qualified specialist will ensure that you use the proper type of screed for the room's intended purpose and get the optimum lifespan out of your floor. The correct mix of screed and the methods used in laying it are also critical to guarantee the final durability of your floor.
There are numerous screeding companies in and around Knottingley so see if you can get multiple quotes for your screeding project before choosing a contractor and know to what standard of finish is it for. The quote could be based on what's called the Surface Regularity, or SR number. SR1 is the best level, and whilst SR2 and SR3 may seem less costly at first glance, they don't guarantee a totally even or flat floor surface. An SR2 or SR3 level could mean there are flat spots or ridges that might cause issues when putting down your final flooring materials.
British Standards BS8204 lays down the guidelines and regulations that all Knottingley screeding contractors must follow, and if applying specialist screeding solutions, (Flowcrete, Gypsol, Cemfloor etc), they ought to be certified by the manufacturers as being skilled and trained in their use. A contractor holding accreditations indicates that they have been trained and assessed in the use of these screeding products and can offer a high quality service in all aspects of their installation.
Commercial screeders in Knottingley will generally tackle larger screeding projects in warehouses, factories, hospitals, schools, shopping centres and salons.
TYPES OF SCREED
Standard Screeds - A combination of cement and sand which is okay for standard domestic usage. 5 parts sand to 1 part cement is the normal mixture for standard screeds. Once its been laid this 5:1 ratio dries at a rate of 1mm each day.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum durability and strength is essential.
Fibre Reinforced Screed - The favoured option where underfloor heating is being installed in residential homes in Knottingley. This is due to the increased durability and protection against thermal shrinkage and cracking offered by the special fibres within the screed. At around 1mm per day, it has a similar drying rate to standard screed.
Advanced Drying and Fast Drying Screeds - As the name suggest, this screed dries at a quicker rate and allows you to use the floor area much faster. These are usually a fibre reinforced type of screed which can dry at a rate of between three and seven millimetres per day and are used in time dependent projects.
Self-Levelling or Liquid Screeds - A latex and cement material which can produce the highest standard of finish to SR1 levels. The self-levelling compound provides a clean and smooth surface over a rough substrate or damaged floor to enable all flooring materials to be laid. These can be as little as 1mm thick, and due to the latex polymers, will still provide high strength.
Polymer Screeds - These provide a high level of strength with a lower thickness. The drying times for these vary as outlined by product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to fully prepare all areas before proceeding with any other work in order to ensure a hard wearing and quality screed flooring. The original floor surfaces should be cleaned to eradicate any paint, grease, debris and oil which can affect the adhesion of the screed.
If any cleaning products are used in this process it is crucial to make certain that no residues of detergents, soaps or other cleaning products are left on the floor surface and it's allowed to dry out naturally. If screeding over a cement or stone floor all cracks should be mended to prevent them from "travelling" up through a screed layer and producing imperfections on the final surface. During a site survey your Knottingley screeding installer will notice what preparations are required before any actual screeding starts.
To protect the screeding layer and flooring materials from dampness rising up through the ground, a damp proof membrane (DPM) will have to be installed. There might be two or three layers of varying thickness polythene to act as a barrier between the insulation layer and screed.
Another air-tight barrier might be needed if your house is in an area that's known to be prone to radon. A simple airtight membrane might be suitable in places with relatively low levels of radon, but in more extreme situations there might need to be a more sophisticated extraction system to remove any harmful radon gases.
Once these steps have been taken the screeding company will apply a sealer or primer to the prepared base surface. These primers and sealers will make sure the screed bonds perfectly to the base surface and help produce a quality finished floor. These materials need certified tradesmen to apply them in the correct proportions by using airless sprays and other tailor-made equipment.
Before the screeding can be poured, any underfloor heating (if required) will now be installed. The under floor heating system will be carefully positioned and mounted firmly on insulation panels to stop any movement during screed pouring process. Warmth will be evenly spread across the floor in a professionally fitted underfloor heating system, and coupled with it being an efficient method of heating, it's a great choice for the majority of Knottingley home restoration projects.
If you aren't installing underfloor heating the screed can now be prepared in situ and poured. Your intended use of the room will help your screeding specialist on what type of screed is perfect for your requirements. After the pouring of the screed there'll be at least twenty four hours (for advanced and quick drying screeds) before you are able to walk over the surface, and a 72 hours minimum drying period for the laying of any flooring materials. If you are laying standard or heavy duty screeds the curing time is longer and you must observe the manufacturer's guidelines so as to get the best finish to your floor.
Once the screeding has hardened it can be quality checked to verify its SR level. The test involves using a 2 mtr straight edge laid down upon the surface and any fluctuations from true are calculated.
- SR1 - Disparities of 3 millimetres or less as measured over the entire floor area shows your screeding to be of the best quality and is categorised as SR1.
- SR2 - The normal standard flooring in industrial and commercial builds is classed as SR2 and has a maximum deviation of 5 millimetres across the entire floor surface.
- SR3 - For other floors where the quality of finish is relatively immaterial SR3 is the specification and has a deviation measurement of 10mm or less.
If you need load bearing checks, a qualified structural engineer is necessary to perform the testing. The testing will ensure your newly laid screeded surface is viable for the load bearing requirements laid out in the site survey. The screed layer will be subjected to a drop hammer test to assess strength and flexibility in various areas. The specialist measurement and testing tools mean that this can only be carried out by a trained structural engineer following the guidelines of BS8204.

Screed Reinforcement
Screed reinforcement is a method of reinforcing concrete screeds to improve their durability and strength. Screeds are thin, flat layers of concrete that are applied to a base layer to create a level surface. They find common use in construction projects as flooring, but they can also be utilised as a finishing layer for walls and ceilings.
Screed mixture during installation is infused with reinforcement materials, such as wire, polypropylene fibres or steel mesh, to improve strength and prevent cracking. This reinforcement improves the surface's ability to resist impact, abrasion and thermal changes, while also ensuring that load and weight are evenly distributed.
By reducing the risk of cracking and shrinkage caused by humidity or temperature changes, reinforcement improves both the durability and strength of screeds. To avoid displacement over time and ensure consistent distribution throughout the screed, the reinforcement must be properly installed, which is crucial. To maintain the quality and structural integrity of screeds, it is essential to use screed reinforcement, resulting in a reliable and long-lasting surface for a range of applications.
Screed Floor Removal
Screed floor removal is a process that is crucial in renovation and construction. It is used to strip away existing layers of screed from floor surfaces. When upgrading or renovating a floor, this procedure is essential. It facilitates the preparation of the surface for the new flooring material or other improvements.
Expert contractors with experience in screed floor removal play a vital role in performing this complex task. The safe and efficient elimination of the old screeding is what sets the stage for a fresh start for your floor, and their proficiency guarantees that this happens. The significance of this fresh start is manifold, including changes in design, upgrades and repairs.
With the right tools and methods, removing a screed floor is a straightforward process. Careful consideration is needed for both the thickness and type of the existing screed and the surface to which it is applied. This attention to detail ensures that the removal is carried out successfully, with minimal disruption to the underlying structure.
One of the main benefits of removing floor screed is the opportunity to address any underlying problems that might have developed over time, which is an important factor to consider. If the old layer of screed is uneven, damaged, or otherwise compromised, its removal allows for a detailed examination of the substrate. This inspection enables flooring contractors to ensure that the substrate is structurally sound and ready for the installation of new flooring materials. (78016 - Floor Screed Removal Knottingley)
