Floor Screeding Charminster Dorset (DT2): If you are hoping to install underfloor heating, are renovating a property or cellar or have a damaged or uneven floor in your Charminster home, then it's time to think about hiring a floor screeding professional. To provide a level foundation for your choice of top flooring material, a screed is used to generate a smooth floor surface over a concrete sub-base. Floor screeding will provide a durable, quality finish for any room.
FLOOR SCREEDING COMPANIES CHARMINSTER
Supplying the experience and correct working practices to establish a perfect base for your floor, a floor screeding company in Charminster can help you no matter what shape or size of room or area you're remodeling. When your flooring project has been diligently assessed, they'll be able to inform you of the correct form of screed needed for your project, and the best methods for applying and installing it.
It may be a requirement, based on the intended use of the space, for a survey by a structural engineer to conform to building regulations on flex strength, point loadings and load requirements of the screed floor.
Working with a qualified and skilled contractor will guarantee you use the right type of screed for the room's intended purpose and get the optimum lifespan out of the resulting floor. Choosing the right screeding materials and the method of installation is critical if you want to finish up with a durable and quality finish for your floor surface.
Before picking out a screeding contractor from those operating in the Charminster area, ask to what standard of finish they are basing their estimate, and also ensure you get two or three quotations. For residential homes a quotation will generally be provided for an SR (Surface Regularity) calculation of SR1 or SR2. SR2 and SR3 may be cheaper options, however the finished floor surface might have deviations and errors, whilst SR1 guarantees a pretty much perfect finish. This could mean that you may have to fix any areas that might cause issues when putting down your finished flooring material.
British Standards BS8204 sets down the regulations and guidelines that all Charminster screeding companies is obliged to follow, and if using specialist screeding solutions, (Gypsol, Flowcrete, Cemfloor etc), they ought to be approved by the manufacturers as being skilled and trained in their use. The assessment and training of a screeding company by a manufacturer is underlined by the use of the accreditation scheme, and gives assurances of safe working practices and reliability on any project involving their materials.
Commercial screeders in Charminster will generally tackle screeding projects in hospitals, salons, factories, schools, warehouses and shopping centres.
TYPES OF SCREED
Standard Screeds - Frequently used in residential projects where the mixture of cement and sand is perfectly acceptable for everyday floor traffic use. The ratios involved are 5 parts sand to 1 part cement. After laying a standard flooring screed dries out at a rate of just 1mm/day.
Fast Drying and Advanced Drying Screeds - As the name suggest, these screeds dry quickly and allow you to use the screeded area much sooner. Drying at a rate of 3-7mm, subject to the mixture, they are usually a fibre reinforced kind of screed and are great for projects which have tight schedules.
Fibre Reinforced Screed - The preferred choice by professional contractors for use in combination with under floor heating systems. The special fibres in the screed improve overall durability and strength whilst also safeguarding against thermal shrinkage and cracking. It dries at the same rate as a standard screed of 1mm per day.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially in SR1 levels of screeding, by a latex and cement mixture. The self-levelling compound provides a clean and smooth surface over a rough substrate or damaged floor to allow all sorts of flooring materials to be laid. These can be as little as one millimetre thick, and due to the latex polymers, will still provide high strength.
Industrial and Heavy Duty Screed - A screed designed for heavy traffic and high load areas where the maximum possible durability and strength is necessary.
Polymer Screeds - These provide an extremely high level of strength with a lower thickness. Due to their different chemical compositions, these polymer screeds have varying drying times which can be verified by checking manufacturer's product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will have to prepare the area before any other work in order to guarantee a hard wearing and quality screed flooring. Any oil, paint, grease and debris on the existing floor level can affect the bonding of the screed, and must be removed.
If any products were used in this process it's vital to make certain that no residues of soaps or other cleaning products are left on the floor surface and it's allowed to dry out naturally. It is vital to fix any crevices or cracks in the surface to prevent them being reflected and "travelling" upwards into your freshly screeded floor. A genuine Charminster screeding company will pick up on such aspects during the on-site survey and make sure that all preparations are completed before pressing on with the next stages of the floor screeding process.
To protect the flooring materials and screed layer from dampness rising up through the ground, a DPM (damp proof membrane) must be laid. Different gauges of polythene sheeting may be used as a DPM and also serve as a barrier for the screed and any insulation panels.
A supplementary air-tight barrier could be required if your building is in an area that's regarded as prone to radon gas. If radon gas is present in severe doses then a complete ventilation and extraction system might be needed beneath the layer of screed which will remove any gases that could seep in from ground level.
Once the floor base has been prepared and all DPMs installed, a primer or sealer is then applied. Primers help with the bonding process and are special applications matched to the sort of screed being used. Custom-made equipment such as airless sprays will usually be used to apply a sealant or primer, by professional screeding companies in Charminster sticking to the manufacturer's guidelines and safety advice.
If you are installing under floor heating, this is the time that it will need to be correctly laid out and installed. Insulation panels will be put in position and the heating pipes and wires will be firmly mounted to prevent any movement while the screed is applied. Under floor heating is one of the most effective ways to heat a room and an expertly installed system should provide even warmth all over the floor.
The screed can now be prepared on site and poured onto the floor base. Your screeding contractor will give you advice on which sort of screed is appropriate for your needs, in line with your intended use of the room. Remember that even quick drying screeds have a minimum of 24 hours before you can walk over any laid surface and a minimum three days before any flooring can be fitted. If you are laying heavy duty or standard screeds the setting time is longer and you must follow the manufacturer's guidelines in order to get the best possible finish to your floor.
The SR level of your screeding can be checked once it has solidified sufficiently to be walked on. Through the use of a 2m straight-edge the surface is examined for any deviations, dips and ridges in the screed surface.
- SR1 - Disparities of three millimetres or less being measured across the whole floor area shows your screed to be of the finest quality and specified as SR1.
- SR2 - If the floor surface has a deviation from the straight-edge of five millimetres or less it is classified as SR2 quality and is the normal standard for industrial and commercial floors.
- SR3 - For other floors where the finish is relatively immaterial SR3 is the standard and should have a deviation measurement of 10 millimetres or less.
It might also be necessary for a qualified structural engineer to conduct a soundness test. Using specialist equipment the structural engineer will establish the screed strength and viability of use in a load bearing setting. This will include what's known as a "drop hammer test" which assesses various aspects of the flexibility and strength of the screed. Any screed flooring that's got load bearing requirements must be okayed by a fully qualified structural engineer heeding the BS8204 guidelines.

Granolithic Screeding
Granolithic screeding is a process of creating a smooth and even surface for floor coverings like tiles or carpets. It involves mixing aggregate, cement and sand to form a mixture, which is then applied to a concrete base. The mixture is levelled with a straight edge to give it a smooth surface.
This technique is typically used in commercial and industrial buildings, high-traffic residential areas, and spaces that require chemical and abrasion resistance. The resulting surface is durable, easy to clean, and provides the perfect base for other flooring materials.
Granolithic screeding is typically applied over a concrete base, and the surface is typically treated with a curing compound to ensure it sets properly. As soon as it has cured, it creates a seamless floor with a smooth, hard surface that is resistant to excessive wear. It's also resistant to chemicals and water, which makes it well suited for use in environments where there's a chance of spills or exposure to hazardous materials.
Latex Screed Charminster
It is best to use a latex floor screed when a bit of flexibility is necessary in the surface of a floor. Latex floor screeds come in two parts - a bottle and a bag - with the bottle containing liquid latex and the bag containing a cement based powder. Whereby water is normally used in a screed mix, this is replaced with the latex liquid, meaning that it is more flexible than standard screeds, and quicker drying.
This latex compound is used for levelling sub-floors in advance of the installation of your chosen decorative covering. Giving a durable and smooth surface that's ideal for the application of flooring adhesives, this is is suitable for use on sub-floors of concrete, asphalt, quarry tiles, wood and sand/cement. If there's a bit of movement in the subfloor this type of screeding will give you a flexible, crack-free finish on which to lay your chosen floor coverings.
With "floating" screeds, for instance when an unbonded screed is being laid on the top of a membrane of thermal or acoustic insulation, latex floor screeds will not be suitable. Floating screeds with a thickness of 50 to 65 millimetres are generally used on top of underfloor heating.
