Floor Screeding Leiston Suffolk (IP16): If you have a damaged or uneven floor, are renovating a property or basement or are hoping to install underfloor heating, then making contact with a specialist service in Leiston is your best option. Floor screeding gives a smooth finish to a rough sub-base, and enables you to lay a suitable flooring material, (boards, carpets, tiles etc) over the top of it. To ensure a durable and quality finish to the whole floor surface, screeding is an important process.
FLOOR SCREEDING CONTRACTORS LEISTON
A reputablein Leiston will have knowledge and experience to help you achieve a perfectly finished floor in whichever shape or size of room you're working on. They'll be able to advise you on the right kind of screed that your project requires, and how best to apply and install it.
It might be a requirement, depending on the intended use of the area, for a survey by a structural engineer to conform with building regulations on load requirements, flex strength and point loadings of the screed floor.
The training and skills that a certified screeding specialist brings to your project will guarantee a high quality result and help to lengthen the life of your floors. Choosing the correct screeding materials and the method of installation is vital if you want a durable and quality finish for your floor surface.
There are manycontractors in the Leiston area so if possible get multiple quotes for your project before picking a contractor and know to what standard of finish is it for. For residential properties a quotation will normally be provided for a Surface Regularity (SR) standard of SR1 or SR2. SR2 and SR3 might be cheaper options, however the floor screeding finish may have errors and deviations, whilst SR1 guarantees a perfect quality of finish. This could mean that you may have to fix any patches that could cause problems when putting down your final flooring material.
All Leiston screeding companies have to stick to British Standards (BS8204) and should have accreditation from screeding material and equipment manufacturers, e.g. Gypsol, Flowcrete, Cemfloor. This accreditation scheme demonstrates a contractor's high quality performance and training in the application of a manufacturer's products.
Leiston commercialcould be involved in the screeding of floors in factories, salons, schools, warehouses, hospitals and shopping centres.
TYPES OF SCREED
Standard Screeds - Used in residential flooring projects where the mixture of sand and cement is good for everyday floor traffic use. The standard screed is a mixture of five parts sand to one of cement. The standard screed dries at a rate of 1mm thickness per day.
Polymer Screeds - An extremely high strength solution where a reduced screed thickness is necessary. Maker's guidelines for drying times differ across the various product ranges.
Fibre Reinforced Screed - The preferred option where under floor heating is being installed in domestic properties in Leiston. The improved strength and flexibility provided by the fibres in this screed help protect the flooring from thermal shrinkage and cracking. It dries out at the same rate as a standard screed, at about 1mm per day.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum strength and durability is necessary.
Self-Levelling or Liquid Screeds - A cement and latex formula which can produce the highest standard SR1 finish. Primarily used to finalise a poor substrate level or damaged floor in order to lay a brand new flooring surface, such as vinyl planks over it. They can be as little as one millimetre in depth, and due to the, will still provide high strength.
Fast Drying and Advanced Drying Screeds - If you need to move forward urgently with the flooring due to time restraints, this screed dries much faster than standard screeds. Drying out at a rate of 3-7mm, depending on the specialised mix, they're generally atype of screed and are ideal for flooring projects which have tight schedules.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare the area before proceeding with any other work in order to ensure a high quality and hard wearing. It is crucial that any contaminants such as grease, oil, paint or loose debris is eradicated from the floor surface before pouring any screed, as these can affect the bonding capability that a good quality screed needs.
If any products are used during this stage it's vital to make certain that no residues of detergents, soaps or other cleaning products are left on the surface and it is allowed to dry out naturally. It's necessary to fix any cracks or crevices in the base to avoid them being visible and "travelling" up into your freshly screeded floor. A site survey will allow your Leiston screeding specialist to take note of these preparation areas and complete them before beginning to pour the screeding.
Before any screeding can be laid a damp proof membrane (DPM) must be installed to protect the screed and final flooring from moisture. Different gauges of special polythene may be used as a damp proof membrane and also act as a barrier for the screed and any insulation panels.
If the area is at risk from radon gas then one additional barrier is essential to prevent the gas from entering from the ground. This could be as simple as an airtight membrane, or in more serious situations an extraction and ventilation system is installed underneath the screed to draw out any influx of air and gas from the ground.
As soon as the base has been properly prepared and all DPMs installed, a primer or sealant is then applied. Sealers and primers help the bonding process and are special applications specifically designed for the type of screed that is being used. Because of their specialist nature, only certified screeding contractors in Leiston should be entrusted with using them safely and correctly and through the use of bespoke equipment for the task.
Underfloor heating can now be installed and checked before screeding is applied. The heating pipes and wires are securely mounted on insulation panels to prevent any movement and make certain they're held in the correct position. When skillfully installed an under floor heating system is an excellent way to warm up a room and decent quality screed will retain its heat, generating an even heat across the floor surface.
If you aren't fitting under floor heating the screed will now be mixed and prepared on site and laid. Your use of the room will assist the screeding specialist on what type of floor screed is best for your requirements. Remember that even quick drying screeds have a minimum of twenty four hours before you're able to walk on any laid surface and a minimum three days before any flooring materials can be fitted. If you are laying standard or heavy duty screeds the curing time is longer and you must follow the manufacturer's guidelines so as to get the best finish for your floor.
The SR level of your screeding can be confirmed once it's hardened sufficiently to be walked upon. Through the use of a 2m straight-edge the surface is examined for any deviations, dips and ridges in the surface of the screed.
- SR1 - SR1 is the best standard and allows just 3 millimetres of deviation from the straight-edge.
- SR2 - SR2 is for standard commercial and industrial floors and can deviate from the straight-edge by as much as five millimetres.
- SR3 - For a utility area or room where the finish is relatively unimportant the SR3 is the specification and should have a maximum deviation measurement of 10 millimetres or less.
If you need to check the screeded floor for load bearing, a structural engineer is necessary to conduct the tests. The assessment will ensure your newly laid screeded surface is viable for the load point requirements specified in the site survey. A "drop hammer test" is performed at several areas on the screed layer and the results recorded. The specialist testing and measurement tools mean that this can only be performed by a certified structural engineer following the guidelines of the British Standards BS8204.

To enhance the durability and strength of concrete screeds,is utilised. The creation of level surfaces involves applying thin and flat layers of concrete known as screeds to a base layer. In building projects, they have a common use as flooring, and they can also serve as a finishing layer for walls and ceilings.
To prevent cracking and increase strength, reinforcement materials like fibres, steel mesh or wire are mixed into the screed during installation. By distributing load and weight evenly across the surface, reinforcement improves its resistance to abrasion, impact and thermal changes.
By reducing the risk of cracking and shrinkage caused by temperature or humidity changes, reinforcement improves both the durability and strength of screeds. Factors such as load capacity, finish and thickness play a role in the selection of reinforcement material for a project, which can vary according to specific requirements. The use of screed reinforcement is essential for ensuring that screeds maintain their structural integrity and quality, providing a reliable and long-lasting surface for a range of applications.
Latex Floor Screed
When the make-up of your floor's surface means that a degree of flexibility is necessary, it may be an advantage to use a latex screeding, as opposed to one with a rigid finish. Latex screeds normally comprise two parts - a cement-based smoothing compound, and a liquid latex component. The water that is normally used in a screed mix is replaced by the latex liquid, meaning it is more flexible than standard screeds, and quicker drying.
This latex screed is used to level-out a sub-floor prior to the final decorative surface being laid. This screed is appropriate for use on subfloors of sand/cement, concrete, asphalt, wood and stone tiles, to provide a resilient and smooth surface which is perfect for the application of adhesives. Even where there's movement in your subfloor, this type of latex floor screed will provide a crack-free, flexible finish.
When using a "floating" screed, for instance when an unbonded screed is being laid on top of a layer of acoustic or thermal insulation, screed thicknesses of 50-75mm may be necessary, and latex flooring screeds aren't suitable for this purpose.
