If you have a solid floor and want to set up a water-based or wet underfloor heating system, liquid screed is perfect for the job, this is due to its solid floor properties whilst allowing the transfer of heat to pass through.
There are two common types of screed and that’s both dry and self-levelling types. They not only allow you to prepare the surface for the finishing floor covering, but they intake the warmth from the underfloor heating pipework and deploy it into the room above. Liquid screed helps maintain a comfortable atmosphere whilst reducing energy and running costs.
Its recommended that after the underfloor heating is laid in place, you should apply the screed as quickly as possible. We will always pressure test your floor before hand to ensure there are no leaks.
Dry screed comprises a traditional mix of coarse sand an cement, usually in a 4:1 ratio. We ensure that the screed is always mixed well and is well-compacted to guard against damage. In some cases fibres are added to help reduce cracking, or additives can be added for an excel in drying times. Once laid, the drying times will be dependent on the temperature and humidity in the building. Traditional mixes will need roughly 28 days before the heating can be used.
Also known as liquid screed, the mixture is poured or pumped onto the floor and spreads out across the entire surface to achieve a level finish.
This process is quick and easy, it can reduce the risk of unwelcome voids forming on the finished floor. It can usually be laid thinner than dry versions – around 50mm in conjunction with wet underfloor heating. The mixture is very quick to lay so it’s especially suited to larger areas, but it will take longer to cure than dry screed.
