TYPES OF SCREED
Standard Screeds - A blend of cement and sand which is acceptable for basic residential usage. This mixture comprises a 5:1 ratio of sand to cement. Once its been laid this 5:1 ratio will dry at a rate of 1mm each day.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading of the floor is required, heavy duty screeds provide maximum durability and strength.
Fast Drying and Advanced Drying Screeds - If you have to progress urgently with the work due to time limitations, this screed dries much faster than standard screeds. They're usually a fibre reinforced screed that dries out at a rate of between three and seven millimetres per day and are employed in time dependent projects.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially where SR1 levels are necessary, by a latex and cement mixture. It is mostly needed to provide a smooth, clean floor over a damaged or poor quality substrate and results in a finish onto which all kinds of flooring materials can be laid. Even with a depth of only 1mm, the latex polymers within the mixture provide a high strength surface for a variety of uses.
Fibre Reinforced Screed - The preferred choice by professional contractors for use in combination with under floor heating systems. The special fibres in this screed improve overall durability and strength whilst also safeguarding against thermal cracking and shrinkage. It dries at an identical rate to a standard screed, at about one millimetre per day.
Polymer Screeds - A high strength flooring solution where a reduced thickness is essential. On account of their different chemical compositions, these polymer screeds have varying drying times which you can verify by checking manufacturer's own product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will need to fully prepare the area before any other work in order to ensure a hard wearing and quality screed flooring. Any debris, oil, paint and grease on the original floor level can adversely affect the adhesion of the screed, and should be eradicated.
Any cleansing chemicals that are used during this process should leave no residues, and the floor base must be permitted to dry out naturally. It's essential to fix any crevices or cracks in the floor surface to avoid them being mirrored and "travelling" upwards into the newly screeded floor. A genuine Caterham screeding specialist will pick up on such issues during the site survey and ensure that all preparations are finished before moving on to the next stages of the screeding process.
To shield the screed layer and flooring materials from moisture rising up through the ground, a damp proof membrane (DPM) must be installed. The damp proof membrane is made from thick polythene sheet and different layers may be used to act as a moisture barrier for the screeding.
If your home is located in an area where radon gas is present an additional barrier layer is needed to stop radon gas from getting through. An air-tight membrane may be suitable in areas with low radon emissions, but in more serious cases there might have to be a more complicated extraction and ventilation system to take away any ground penetrating radon.
Once these steps have been taken the screeding company will apply a sealant or primer to the prepared floor base. A primer helps with the screed to bond successfully to the base surface and different varieties exist according to which kind of screed is being used. Custom-made equipment such as airless sprays will usually be used to apply a primer or sealant, by experienced screeding contractors in Caterham sticking to the manufacturer's guidelines.
If you are installing under floor heating, now is the time that it will need to be laid out and installed. The underfloor heating system will be carefully positioned and secured firmly to insulation panels to prevent any movement during screed pouring process. Underfloor heating is one of the most effective ways to heat a room and a skillfully installed system will give an even warmth all over the floor.
If you're not putting in underfloor heating the screed can now be mixed and prepared on site and poured. Your proposed use of the room will assist the screeding company on which kind of screed is perfect for your requirements. After the pouring of the screed there is a minimum 24 hours (for quick drying and advanced screeds) before you're able to walk over the surface, and a 72 hrs minimum setting period for any floor covering installations. Manufacturer's drying instructions for standard and heavy duty screeds must be observed in order to achieve a quality finish and provide a stable and long lasting floor surface.
You can test the SR level of the completed screed as soon as it is set enough for walking on. Using a 2 metre straight-edge the surface is checked for any ridges, deviations and dips in the screed surface.
- SR1 - Over the whole area, if there aren't any disparities of more than 3 millimetres from the straight-edge, you've got a top quality SR1 level surface.
- SR2 - The standard flooring in commercial and industrial builds is normally SR2 and has a maximum possible deviation of 5mm across the entire screed.
- SR3 - SR3 is utility standard where a perfect quality finish isn't required. This classification can have a maximum permissible deviation of 10 millimetres.
If you require load bearing checks, a structural engineer is needed to conduct the tests. The assessment will ensure your new screeding is viable for the load point requirements set down in the original site survey. This will include a "drop hammer test" which records specific data on the flexibility and strength of the screed. The precise measurement and testing tools mean that this can only be carried out by a fully qualified structural engineer respecting the guidelines of the British Standards BS8204.
