Floor Screeding Great Notley Essex (CM77): If you have a damaged or uneven floor, are restoring a property or basement or are hoping to install under floor heating, then you'll be needing to find a specialist floor screeding service to help you. Allowing you to lay your final layer of flooring material, (carpets, tiles, boards etc) over the top of it, floor screeding provides a smooth, level finish to a basic sub-base floor. If you would like your floors to last a long time then floor screeding is one of the most important factors in any renovation or building project.
FLOOR SCREEDING EXPERTS GREAT NOTLEY
Having all the experience and knowledge to help you achieve a perfectly finished floor in whatever shape or size of room you are renovating, a professional screeding contractor in Great Notley is the best choice for your screeding project. Once your screeding project has been carefully assessed, they will be able to inform you of the correct form of screed needed for your project, and the best methods for applying and installing it.
Your screeding specialist will also let you know if a structural engineer is required for your undertaking, to check on any point loadings, load bearing and flex strength that your flooring might require to conform with current building regulations and British Standards.
Skilled and qualified trades-people are necessary for a successful result and will extend the life of your floor by using the right type of screed for the intended purpose of your room. There are many kinds of screeding and selecting the correct mix and laying process is vital to create a top quality floor that is both fit for purpose and long-lasting.
There are many screeding companies in the Great Notley area so see if you can get multiple price quotes for your project before choosing a contractor and know to what standard of finish is it for. For domestic properties a quotation will generally be provided for an SR (Surface Regularity) calculation of SR1 or SR2. SR2 and SR3 will be less costly options, but the finished floor surface might have deviations and errors, whilst SR1 guarantees a perfect finish. Any errors in the screeding (as might arise with SR2 or SR3) can cause problems in laying flooring due to ridges, flat spots, indentations in the floor surface.
British Standards BS8204 lays down the guidelines and regulations that all Great Notley screeding installers must follow, and if working with specialist screeding solutions, (Cemfloor, Gypsol, Flowcrete etc), they ought to be accredited by the manufacturers as being trained and skilled in their use. A company holding accreditation indicates they have been trained and assessed in the use of these products and can offer a top notch service in all areas of their installation.
For larger screeding projects in pubs, warehouses, factories, schools, hospitals and shops, skilled commercial screeders in Great Notley will be needed.
TYPES OF SCREED
Standard Screeds - A blend of sand and cement which is ideal for basic residential usage. The standard screed is a mixture of 5 parts sand to 1 of cement. The standard flooring screed dries at a rate of 1mm thickness per day.
Polymer Screeds - Provides a high level of strength with a lower thickness. Owing to their different chemical compositions, these polymer screeds have varying curing times which you can verify by studying manufacturer's guidelines.
Self-Levelling or Liquid Screeds - Used to produce the highest quality of finish, especially in SR1 levels of screeding, by a latex and cement formula. Typically used to finish off a poor substrate level or damaged floor so as to lay a brand new flooring surface, like vinyl planks on the top of it. Even with a thickness of only 1mm, the latex polymers within the mixture provide a high strength surface for a wide variety of uses.
Fast Drying and Advanced Drying Screeds - If you have to press ahead urgently with the flooring because of time restraints, these screeds dry more speedily than standard flooring screeds. Drying out at a rate of three to seven millimetres, depending on the mixture, they're usually a fibre reinforced type of screed and are ideal for projects which have tight deadlines.
Industrial and Heavy Duty Screed - A screed that is designed for heavy traffic and high load areas where maximum strength and durability is crucial.
Fibre Reinforced Screed - The expert's choice for domestic use on top of underfloor heating. This is due to the improved durability and protection against thermal cracking and shrinkage provided by the fibres within the screed. At approximately one millimetre per day, it has the same drying rate to standard floor screed.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a high quality screed surface that will be hard wearing and durable. It is crucial that any contaminants such as grease, loose debris, paint or oil is eradicated from the base before pouring any screed, because these can affect the bonding capability that a quality screed requires.
If cleaning products have been used it is crucial to remove any remnants of soap, detergent etc, and leave the surface to dry naturally. If screeding over a stone or cement floor then all cracks should be repaired to stop them from "travelling" through your screed layer and causing imperfections on the finished surface. A decent Great Notley screeding installer will take note of these problems during a site survey and ensure that all preparations are completed before moving on to the next steps in the floor screeding process.
To protect the screed layer and flooring materials from dampness rising up from the ground, a damp proof membrane (DPM) will have to be laid. Different thicknesses of polythene sheeting could be used as a DPM and also serve as a buffer for the screed and any insulation material.
If the area is susceptible to radon then another barrier is required to stop this harmful gas from entering via the ground. If radon gas occurs in large amounts then a full ventilation and extraction system may be installed underneath the screed which will extract any gases that could seep in from the ground.
Once the floor base has been properly prepared and all membranes installed, a primer or sealant is then put on. A primer helps with the screed to bond to the base and membranes and different types exist according to which kind of screed is being used. These products require experienced contractors to apply them in the correct ratios by using bespoke equipment, such as airless sprays.
Before any screed is laid, any under floor heating will now set out and installed. Insulation panels will be put in position and the wires and heating pipes will be securely fastened to prevent any movement while the screed is being applied. When properly installed an under floor heating system is an effective way to warm up a room and high quality screeding will retain its heat, generating an even level of warmth across the floor.
If you're not installing underfloor heating the screed can now be mixed and prepared in situ and laid. Your screeding contractor will have given you advice and guidance on which form of screed is appropriate for your needs, in line with your proposed use of the room. For quick drying screeds there'll be at least a 24 hour delay before it is able to be walked over, and a further seventy two hours minimum before you can lay any flooring materials. Such timescales will be longer for heavy duty and standard screeds and the manufacture's instructions must be followed to create the best finish and longevity of the floor.
Once the screed has solidified it can be quality checked to establish its SR standard. The standard SR test involves the use of a 2m long straight-edge to check for any fluctuations in the screed surface.
- SR1 - Over the entire screed area, if there are no deviations greater than 3 millimetres from the straight-edge, you've got a top quality SR1 standard surface.
- SR2 - The normal standard flooring in industrial and commercial builds is normally SR2 and has a maximum deviation of 5mm across the whole screed.
- SR3 - For utility floors where the quality of finish is fairly unimportant SR3 is the specification and has a maximum deviation measurement of 10mm or less.
If you require load bearing checks, a qualified structural engineer is necessary to perform the tests. The testing will ensure your newly laid screed surface is suitable for the load bearing requirements laid out in the site survey. This should include what is known as a "drop hammer test" which records specific data on the strength and flexibility of the screed. The specialist measurement and testing tools required mean this can only be conducted by a certified structural engineer observing the guidelines of BS8204.

Latex Screed Great Notley
When a floor's surface needs a certain degree of flexibility, it may be better to use a latex screeding. Latex screeds come in two parts - a bag and a bottle - with the bottle containing liquid latex and the bag containing a cement based smoothing compound. Latex screeds are more flexible and quicker drying than other types of screed, as the water that is normally used is substituted for the liquid latex.
Used in the levelling of sub-floors, this latex product creates a surface for the installation of the final floor finish. This screed is suitable for sub-floors made of wood, concrete, quarry tiles, asphalt or sand/cement, is ideal for the application of adhesives and gives a durable and smooth surface. If there is a bit of movement in the subfloor this latex floor screed will produce a flexible, crack-free finish on which you can lay your final floor coverings.
When installing a "floating" screed, for example when a screed is being laid over the top of a layer of thermal or acoustic insulation, screed thicknesses of 50-75mm may be needed, and latex floor screeds aren't appropriate for this purpose.
Granolithic Screeding
Granolithic screeding refers to a type of flooring that consists of a mixture of cement, sand and aggregate. It is applied in a relatively thin layer and then smoothed to provide a durable, seamless and hard-wearing surface. It is typically used in commercial, industrial and public buildings where heavy traffic is expected.
The resulting flooring is hard-wearing, easy to clean and slip-resistant, making it ideal for use in areas with high foot traffic, such as shopping centres, schools and factories.
The granolithic screeding process involves several steps, including preparing the concrete base, blending of the screed mixture, laying of the mixture, and curing of the screed. Correct mixing, application and curing methods are vital to guarantee the durability and strength of the final surface. Additionally, the screed should be allowed to cure fully before any flooring materials are installed on top of it.
What Does Screeindg Do?
Screeding serves several important purposes in construction projects:
- Even Load Distribution.
- Stability and Structural Integrity.
- Compatibility with Floor Finishes.
- Underfloor Heating System Support.
