Supplying the experience and proper working methods to generate the perfect base for your floors, a floor screeding company in Little Paxton can assist you with whatever shape or size of room you are renovating. After analyzing your project they will give you advice about the optimal choice of screeding and which strategy for applying it is most suited to your situation.
They will also assess if a structural engineer is needed to make sure that any flex strength, point loadings and load requirements are met as set out in the building regulations.
Working with a skilled and qualified contractor will ensure you get the correct type of screed for the room's proposed purpose to extend the lifetime of your floor. A correct mixture of screed and the way it is laid is also vital to ensure the final intergrity of your floor.
There are numerous screeding specialists in and around Little Paxton so see if you can get multiple price quotes for your screeding project before picking a contractor and know to what standard of finish is it for. The quote may be based on what's known as the SR, or Surface Regularity figure. SR1 is the highest standard, and while SR2 and SR3 may be less expensive initially, they do not guarantee a perfectly even or flat floor surface. An SR2 or SR3 level could mean there will be flat spots or ridges that might cause problems when installing your final floor surface.
The guidelines and regulations specified in the British Standards BS8204 must be followed by any Little Paxton floor screeding contractor and they must also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Gypsol, Flowcrete etc.) to prove their safe working practices and competence. The assessment and training of a floor screeding contractor by a manufacturer is highlighted by the use of this accreditation scheme, and offers assurances of reliability and safe working practices on any project involving their materials.
Little Paxton commercial screeders might be involved in floor screeding in boutiques, shopping centres, hospitals, factories, schools and warehouses.
TYPES OF SCREED
Standard Screeds - This is ideal for everyday domestic use and comprises a combination of sand and cement. The standard screed is a mixture of 5 parts sand to one cement. This 5 to 1 ratio standard screed will set hard at a rate of just 1mm per day after laying.
Liquid or Self-Levelling Screeds - When a high standard of finish is needed this compound of cement and latex is employed to achieve SR1 quality screed flooring. The self-levelling compound provides a smooth and level surface over a rough substrate or damaged floor to allow all flooring materials to be laid. The liquid screed can be poured to a depth of only 1mm, but will still provide a high strength base for a varied selection of flooring materials.
Fibre Reinforced Screed - The favoured choice by professional screeders for use in combination with under floor heating systems. The special fibres in this screed improve it's strength and durability whilst also safeguarding against thermal cracking and shrinkage. At approximately 1mm per day, it has the same setting rate to standard screed.
Polymer Screeds - When a reduced thickness of floor is necessary because of building factors, a polymer screed offers an extremely high strength resolution to the situation. Because of their different chemical compositions, these polymer screeds have varying drying times which can be verified by viewing manufacturer's own product guidelines.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is needed, heavy duty screeds allow for maximum strength and durability.
Advanced Drying and Fast Drying Screeds - If there's a need to use the area ASAP a fast drying screed may be used. Drying at a rate of three to seven millimetres, subject to the mixture, they're typically a fibre reinforced type of screed and are perfect for flooring projects that have tight deadlines.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a good quality finish which is hard wearing and durable, time should be spent on fully preparing the area prior to any screeding material being laid. Any grease, oil, paint and debris on the existing floor level can affect the adhesion of the screed, and must be removed.
If any products were used during this stage it's important to ensure that no residues of soaps or detergents are left on the floor surface and it's permitted to dry out naturally. At this stage cracks should be mended since these can travel up through your laid screed and be visible in the finished floor surface. A professional Little Paxton screeding installer will take note of such aspects during the on-site survey and make certain all preparations are complete before applying the next stages of the floor screeding process.
Before any screeding can be poured a damp proof membrane (DPM) must be installed to shield the final flooring and screed from moisture. Different gauges of specialised polythene might be used as a DPM and also act as a barrier for the screed and any insulation panels.
If the area where you live is susceptible to radon gas then a further barrier is required to prevent this harmful gas from entering via the ground. This could be as simple as an airtight membrane, or in more serious instances a ventilation and extraction system is installed under the screeding to extract any influx of air and gas from ground level.
The final step of surface preparation is the painting or spraying of a primer or sealer. A primer assists in the screed bonding process to the base and membranes and different varieties exist based upon which kind of screed is being used. These substances need professional technicians to apply them in the right ratios by using bespoke equipment, such as airless sprays.
Before any screed is poured, any under floor heating (if required) will now be laid out. Insulation panels can be put in position and the heating pipes and cables will be firmly fastened so there's no movement while the screed is poured. When skillfully installed an under floor heating system is an effective way to warm a room and decent quality screeding retains its heat, creating an even level of warmth right across the floor.
Needless to say, if you are not installing under floor heating, you simply bypass this step and get on with applying the screed. The specific requirements of the room will dictate the type of screeding that is used. After application of the screed there will be a minimum 24 hours (for quick drying screeds) before you can walk over the surface, and a 72 hrs minimum setting time before any floor material installation. If you are looking to wind up with a well finished and long-lasting floor surface you must follow the manufacturer's guidelines with regard to standard and heavy duty screeds where this waiting period will be increased.
Once the screed has solidified it can be checked for quality to determine its SR level. Through the use of a 2 metre straight-edge the floor surface is examined for any dips, deviations and ridges in the surface of the screed.
- SR1 - SR1 is the best specification and allows just 3 millimetres of deviation from the straight-edge.
- SR2 - The normal standard flooring in commercial and industrial builds is classed as SR2 and has a maximum possible deviation of 5 millimetres across the entire screeded surface.
- SR3 - For other floors where the finish is fairly unimportant the SR3 is the standard and should have a deviation measurement of 10 millimetres or less.
If your screed has been laid with particular loading in mind then a qualified structural engineer will be required to carry out the assessment. The assessment will make certain that your new screeding is viable for the load bearing requirements laid out in the site survey. An assessment called the drop hammer test will be performed at several areas on the screed and the outcomes recorded. The precise testing and measurement tools needed mean that this can only be undertaken by a competent structural engineer respecting the BS8204 guidelines.

What Does Screeding Do?
There are several significant purposes that screeding serves in construction projects:
- Structural Integrity and Stability.
- Corrections to Subfloors.
- Load Distribution.
- Improving Sound and Thermal Insulation.
- Support for Underfloor Heating Systems.
- Compatibility with Floor Finishes.
- Surface Protection.
- Smoothing and Levelling.
Essentially, a level, stable and durable floor surface is achieved through the crucial role of screeding. The floor finish is assured of a solid foundation, ensuring its maintenance of aesthetics and quality, and ability to withstand the demands of daily use over an extended period.
Screed Reinforcement
For improved strength and durability, concrete screeds can be reinforced using screed reinforcement. To create a level surface, a base layer is coated with flat and thin layers of concrete called screeds. Their typical application in building projects is as flooring, although they can also be used as a finishing layer for ceilings and walls.
In order to enhance strength and prevent cracking, the screed mixture is enriched with reinforcement materials such as wire, steel mesh or polypropylene fibres during installation. Reinforcement aids in the even distribution of weight and load on the surface, while also improving its resistance to thermal changes, abrasion and impact.
In addition to increasing the durability and strength of screeds, the reinforcement process decreases the likelihood of shrinkage and cracking caused by changes in humidity or temperature. Essential to consistent distribution throughout the screed and avoiding displacement over time is the proper installation of the reinforcement. The incorporation of screed reinforcement enables building professionals to ensure that their projects will stand the test of time and provide a functional, high-quality surface for many years to come.
Latex Screed
When the nature of your floor's surface means that a certain amount of flexibility is required, it will be advantageous to use a latex screed, rather than one with a more rigid finish. Normally coming in two parts, latex floor screeds comprise a cement-based smoothing compound, and a liquid latex component. Where water is normally used in a screed mix, this is replaced with the latex liquid, making it more flexible than other types of screed, and quicker drying.
This latex screed is used to level-out a sub-floor before the final decorative surface is installed. This is suitable for subfloors made from concrete, quarry tiles, sand/cement, asphalt or wood, is ideal for the application of flooring adhesives and gives a smooth, durable surface. This latex screeding will give you a crack-free, flexible finish, even if there's movement in your subfloor.
Latex flooring screeds are not a suitable choice where "floating" screeds are needed, for instance when a screed is being laid over a membrane of either acoustic or thermal insulation, such as could be the case when you are screeding over underfloor heating, and thicknesses of 50 to 65 millimetres may be necessary.
