A screed is used to create a smooth floor on top of a concrete sub-base and provide a level base for your choice of top flooring material. To guarantee a high quality and durable finish to the whole floor surface, screeding is a key process.
FLOOR SCREEDING COMPANIES THEYDON BOIS
Whatever shape or size of room you're renovating, a decent floor screeding company in Theydon Bois will provide you with the expertise and proper working methods to generate the perfect base for your floors. They'll be able to advise you on the right kind of screed your project requires, and the best methods for applying and installing it.
Your screeding company will also tell you if a structural engineer is necessary for your project, to evaluate any flex strength, load bearing and point loadings that your screed floor might need to conform with current building regulations and British Standards.
Qualified and skilled tradespeople are imperative for a successful outcome and will extend your floor's lifespan by using the right type of screed for your room's allocated purpose. There are many types of floor screeding and selecting the correct mix and installation technique is essential if you are to create a top quality floor which is durable and fit for purpose.
There are many screeding companies in the Theydon Bois area so make sure you get multiple estimates for your floor screeding project before choosing a company and know to what standard of finish is it for. The Surface Regularity (SR) finish is the number to look for when receiving an estimate from your Theydon Bois screeding contractor. SR2 and SR3 could be cheaper options, although the floor screeding finish could have errors and deviations, whilst SR1 guarantees a perfect quality of finish. An SR2 or SR3 level may mean there are flat spots or ridges that might cause issues when laying your final flooring surface (wood, tile, carpet etc).
The regulations and guidelines set out in in the British Standards BS8204 must be followed by any Theydon Bois floor screeding contractor and they must also hold accreditation with the manufacturers of any specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to prove their competence and safe working practices. This accreditation program illustrates a company's performance and training in the usage of a manufacturer's products.
Theydon Bois commercial screeders could be involved in floor screeding in factories, shopping centres, restaurants, hospitals, warehouses and schools.
TYPES OF SCREED
Standard Screeds - A mixture of sand and cement which is ideal for normal residential usage. 5 parts sand to 1 part cement is the normal mixture for standard flooring screeds. After laying a standard flooring screed sets at a rate of just 1mm/day.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is necessary, heavy duty screeds provide maximum durability and strength.
Polymer Screeds - These provide an extremely high level of strength with a lower thickness. Because of their different chemical compositions, polymer screeds have varying setting times which can be verified by viewing manufacturer's guidelines.
Advanced Drying and Fast Drying Screeds - If there's a need to press ahead urgently with the work on account of time constraints, this screed dries more speedily than standard flooring screeds. These are normally a fibre reinforced type of screed that dries out at a rate of between 3-7mm/day per day and are used in time-sensitive flooring projects.
Fibre Reinforced Screed - The favourite choice of professional screeders for use in combination with underfloor heating systems. The fibres in this screed mix enhance it's strength and durability whilst also safeguarding against thermal cracking and shrinkage. It's got a setting rate of 1mm per day.
Self-Levelling or Liquid Screeds - When a high standard of finish is required this mix of of cement and latex is used to create SR1 level floor screeding. Primarily used to improve a poor substrate level or damaged floor in order to lay a brand new flooring surface, like tiling over it. Even with a thickness of just one millimetre, the latex polymers within the screed provide a high strength surface for a wide range of uses.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to carefully prepare all areas before proceeding with any other work so as to ensure a high quality and hard wearing screed flooring. The original floor surfaces should be cleaned to remove any grease, paint, debris and oil which can affect the bond of the screeding.
Any cleansing chemicals used during this phase shouldn't leave any residues, and the floor surface must be permitted to dry out naturally. If screeding over a cement or stone floor then all cracks should be repaired to prevent them from "travelling" through the screed layer and producing imperfections on the final floor surface. An experienced Theydon Bois screeding installer will take note of these problems during the site survey and make certain that all preparations are finished before applying the next steps in the screeding process.
To protect the screed layer and flooring materials from moisture rising up through the ground, a DPM (damp proof membrane) must be laid. There might be two or three layers of varying thicknesses of polythene to act as barriers between the insulation layer and screed.
If the area where you live is susceptible to radon gas then an additional barrier is essential to prevent the gas from entering from the ground. This can be as simple as an air-tight membrane, or in severe cases a ventilation system will need to be installed underneath the screed to draw out any inflow of air and gas from ground level.
The final step of the surface preparation process is the spraying or painting of a primer or sealer. Sealers and primers help the bonding process and are specialist applications specifically designed for the sort of screed that is being used. These materials need qualified technicians to apply them in the appropriate ratios by using bespoke equipment, such as airless sprays.
If required, this is the time that underfloor heating can be installed and laid out in the correct way. Insulation panels can be positioned and the heating pipes and wires will be firmly fastened to prevent any movement while the screed is being poured. Underfloor heating is one of the most efficient ways to heat a room and a skillfully installed system should deliver even warmth across the floor area.
Naturally, if you are not installing under floor heating, you can just ignore this stage and apply the screed. Your intended use of the room will assist your screeding company on what type of screed is perfect for your needs. For advanced and quick drying screeds there will be at least 24 hours delay before it is able to be walked over, and a further Three days minimum before any flooring material can be laid over it. If you are using standard or heavy duty screeds the setting time is increased and the manufacturer's guidelines must be adhered to in order to get the best possible finish to your floor.
You can evaluate the SR level of the finished screeding once it's set enough for walking on. The test involves the use of a 2 metre long straight-edge laid down upon the surface and any variations from true are measured.
- SR1 - Deviations of 3 millimetres or less being measured across the whole floor area shows your screed to be of the highest quality and classed as SR1.
- SR2 - If the floor deviates from the straight edge by 5 millimetres or less it is SR2 quality and is the normal standard for commercial and industrial floors.
- SR3 - If the deviation is ten millimetres or less the screeding quality is specified as SR3 and is the standard required for utility and garage areas.
It may also be necessary for a structural engineer to conduct a soundness test. Using specialised equipment the engineer will ascertain the screed strength and its suitability for use in a load bearing setting. This can include what's known as a "drop hammer test" which assesses various aspects of the flexibility and strength of the screed. Only fully qualified structural engineers following the British Standards BS8204 guidelines are allowed to conduct these tests and sign off on the structural integrity of the screeding.
