Whatever shape or size of room or area you're remodeling, ain Amesbury will supply the expertise and proper working practices to establish the perfect base for your floor. After a diligent evaluation of your flooring project, they will be in a position to inform you about which method of laying is most effective for your circumstances, and which is the perfect kind of screed.
It may be a requirement, according to the proposed use of the room, for a survey by a structural engineer to abide by building regulations on flex strength, point loadings and load bearing of the screed floor.
A qualified and skilled work force is essential to a successful outcome and will extend your floor's lifespan by using the right sort offor the proposed purpose of your room. There are many kinds of floor screed and selecting the right mix and laying approach is critical to achieve a high quality floor which is fit for purpose and long-lasting.
Before choosing a floor screeding company from any based in the Amesbury area, ask to what standard of finish they are basing their price quote, and also make certain you get multiple price quotes. The Surface Regularity (SR) finish is the number to look for when studying a quote from your Amesbury screeding contractor. SR2 and SR3 may be less expensive options, but the finished floor surface may have deviations and errors, whilst SR1 guarantees a pretty much perfect quality of finish. This could mean that you may need to fix any areas that might cause problems when putting down your final flooring material.
The rules and regulations laid down in the British Standards BS8204 have to be followed by all Amesbury floor screeding companies and they should also hold accreditation with the manufacturers of specialist screeding materials (Flowcrete, Cemfloor, Gypsol etc.) to verify their competence and safe working practices. A company holding accreditations indicates they have been assessed and trained in using these products and can provide a top notch service in all aspects of their installation.
For the screeding of floors in shops, factories, hospitals, schools, pubs and warehouses, dedicated Amesbury commercialwill be needed.
TYPES OF SCREED
Standard Screeds - This is perfect for everyday domestic use and is a mix of sand and cement. 5 parts sand to 1 part cement is the usual mix for standard screeds. The standard screed dries at a rate of 1mm thickness each day.
Fast Drying and Advanced Drying Screeds - As the name would suggest, this screed dries rapidly and allows you to use the floor area much faster. Drying at a rate of 3-7mm/day, depending on the specialised mix, they are normally atype of screed and are suitable for projects that have tight deadlines.
Liquid or Self-Levelling Screeds - A latex and cement solution which can achieve the highest standard of finish to SR1 levels. Mostly used to finalise a damaged floor or poor substrate level to enable the laying of a new flooring surface, like tiles on top of it. Even with a thickness of only 1mm, the latex polymers within the screed provide a high strength surface for a wide range of uses.
Polymer Screeds - A high strength flooring solution where a reduced screed thickness is needed. Because of their different chemical compositions, polymer screeds have varying curing times which you can verify by studying manufacturer's guidelines.
Industrial and Heavy Duty Screed - A screed that's designed for high load and heavy traffic areas where maximum durability and strength is crucial.
Fibre Reinforced Screed - The professional's choice for residential use on top of under floor heating. The special fibres in the screed improve overall durability and strength while also protecting against thermal shrinkage and cracking. The screed will set hard at a rate of roughly 1mm/day.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish which is durable and hard wearing, time should be spent on carefully preparing the area before any screeding material is poured. It is vital that any contaminants such as oil, paint, grease or debris is eradicated from the floor surface before laying any screed, because these can affect the bonding capability that a quality floor screed requires.
If any cleaning products were used during this stage it's vital to make certain that no residues of soaps or other cleaning products are left on the floor surface and it's permitted to dry out naturally. At this point any cracks should be repaired as these can easily travel up through the laid screed and be reflected in the completed floor surface. During a site survey your Amesbury screeding installer will notice what preparation work is required before starting to work on screeding the floor.
A DPM (damp proof membrane) will be applied once the preparation work has been completed to stop ground dampness getting into the screeding and floor materials. Different thicknesses of specialised polythene might be used as a damp proof membrane 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 via the ground. If radon is present in severe doses then a complete extraction and ventilation system might be needed underneath the layer of screed which will extract any gases that could seep in from ground level.
The final step of the surface preparation process is the painting or spraying of a sealant or primer. A primer helps with the screed bonding correctly to the base and membranes and different varieties exist based on which type of screed is being used. Equipment such as airless sprays can be used to apply a sealant or primer, by professional screeding companies in Amesbury following the manufacturer's guidelines and safety advice.
Before any screed can be laid, any underfloor heating will now be laid out. Insulation panels can be laid out and the heating pipes and cables will be firmly attached so there's no movement whilst the screed is being poured. When professionally installed an underfloor heating system is an excellent way to warm up a room and top quality screed will retain its heat, generating an even level of warmth right across the floor surface.
Of course, if you are not installing under floor heating, you can just ignore this stage and apply the screeding. The particular requirements of the room will dictate the sort of screeding used. After the pouring of the screed there'll be at least twenty four hours (for quick drying screeds) before you can walk upon the surface, and a 72 hrs minimum setting period before any floor covering installations. If you're using heavy duty or standard screeds the drying time is increased and the manufacturer's guidelines must be followed so as to get the best possible finish to your floor.
The SR level of your screed can be checked once it has set enough to be walked on. The basic SR test involves the use of a 2m long straight-edge to check for any fluctuations in the screeded surface.
- SR1 - Disparities of 3mm or less as measured over the whole floor area shows your screeding to be of the best quality and classed as SR1.
- SR2 - SR2 is for normal standard floors in commercial and industrial projects and can deviate from the straight-edge by as much as 5 millimetres.
- SR3 - For a utility area or room where the finish is relatively inconsequential SR3 is the standard and should have a deviation measurement of 10mm or less.
If your screeding has been laid with particular loading in mind then a qualified structural engineer is going to be necessary to carry out these soundness tests. The testing will ensure your newly laid screeded surface is viable for the load bearing requirements set down in the original site survey. A drop hammer test will be performed on different areas of the screed and the outcomes documented. Any screed flooring that's got point load requirements must be sanctioned by a trained structural engineer heeding the BS8204 guidelines.

Screed reinforcement is a technique for reinforcing concrete screeds to improve their durability and strength. Screeds are created by applying flat and thin layers of concrete to a base layer, resulting in a level surface. Commonly, they are used in building projects as flooring, but they can also function as a finishing layer for walls and ceilings.
Embedding reinforcement materials, like steel mesh, fibres or wire, into the screed mixture during installation is done to increase strength and prevent cracking. The reinforcement of the surface evens out the distribution of load and weight while also increasing its resistance to thermal changes, impact and abrasion.
In addition to improving the screed's strength and durability, reinforcement also helps to reduce the risk of shrinkage and cracking caused by changes in humidity or temperature. Factors such as finish, thickness and load capacity play a role in the selection of reinforcement material for a project, which can vary according to precise requirements. To ensure that their projects will provide a functional, high-quality surface for many years to come, professional screeders may use screed reinforcement.
