If any products were used in this process it's crucial to make certain that no residues of soaps, detergents or other cleaning products are left on the floor surface and it is permitted to dry out naturally. It is vital to mend any cracks in the surface to prevent them being mirrored and "travelling" up into your freshly screeded floor. During an on-site survey your Derry screeding specialist will be able to see what preparation work is needed before starting to work on the screeding.

Before any screeding can be poured a damp proof membrane (DPM) will have to be put down to shield the final flooring and screed from dampness. The damp proof membrane is made out of thick polythene sheeting and different layers may be used to serve as a moisture barrier for the screeding.

If the area is susceptible to radon gas then another barrier is necessary to stop this harmful gas from entering via the ground. This could be just a simple airtight membrane, or in severe cases a ventilation and extraction system is installed beneath the screed to draw out any inflow of radon gas from the ground.

As soon as the base has been prepared and all DPMs installed, a sealant or primer is then applied. These primers and sealers will ensure the screed bonds properly to the base and help to create a good quality finished floor. Due to their special nature, only trained screeders in Derry are capable of using them correctly, safely and through the use of bespoke equipment for the task.

Now is the time that under floor heating can be laid out in the correct manner and installed. The cabling and heating pipes are securely attached to insulation panels to stop any movement and make sure that they're laid in the correct position. Warmth is spread evenly across the floor in a skillfully installed under floor heating system, and along with it being an effective choice of heating, it is an ideal choice for the majority of Derry renovation projects.

Obviously, if you are not installing underfloor heating, you can just skip this stage and apply the screeding. Your proposed use of the room will assist your screeding specialist on what sort of screed is ideal for your needs. Be aware that even advanced and quick drying screeds have a minimum of twenty four hours before you are able to walk on any laid surfaces and a minimum seventy two hours before any flooring materials can be laid. This period is increased for standard and heavy duty screeds and the manufacture's instructions should be followed to the letter to create the optimal finish and durability of the floor.

You can evaluate the SR level of the finished screeding once it's solidified enough for walking on. Through the use of a 2 metre straight-edge the surface is checked for any ridges, deviations and dips in the surface of the screed.

  • SR1 - Deviations of 3 millimetres or less as measured over the whole area shows your screed floor to be of the finest quality and is classified as SR1.
  • SR2 - The standard flooring in industrial and commercial builds is classed as SR2 and has a maximum possible deviation of five millimetres across the whole floor.
  • SR3 - For other floors where the finish is fairly immaterial the SR3 is the classification and has a maximum deviation measurement of 10 millimetres or less.

It may also be necessary for a structural engineer to perform a soundness test. Using specialist equipment the structural engineer will establish the screeded surface strength and its suitability for use in a load bearing setting. This should include what's known as a "drop hammer test" which assesses various aspects of the strength and flexibility of the screed. Only experienced structural engineers heeding the British Standards BS8204 guidelines are allowed to carry out these tests and sign off on the structural integrity of screed flooring.
