In addition to milling in a Anhydrite floor, Estrich floor slots can be milled in a sand-cement screed. With over 25 years of experience, we know what's involved in installing a wooden floor with underfloor heating. Since the 1960s, sand-cement floors have increasingly been used as screeds. This provides a good basis for using underfloor heating. We also offer the milling of underfloor heating in a sand-cement screed as a separate service.

When the new floor is poured, the pipes can be placed in it. If this option is not available, you can opt for milling the underfloor heating pipes. Before we mill the underfloor heating into the sand-cement floor, we can remove the existing finishing floor for you.

Remove floor

We can remove and dispose of the existing floors for you in consultation. We can remove various floors such as tile, PVC or wooden floors. We ensure that the entire floor is cleared and prepared for milling the underfloor heating . If necessary, we will level the floor and the underfloor heating can be started a day later.

Remove radiators

When installing underfloor heating existing radiators can be omitted if main heating is chosen. A certified plumber can permanently remove the radiators on behalf of Uipkes Wood Flooring . A convector pit can also be omitted; the pit is closed with a repair mortar. After this, you can start installing the underfloor heating .

Underfloor heating into sand-cement screed

We mill the slots with a special floor milling machine based on a sand-cement subfloor. Milling is carried out as dust-free as possible thanks to the special dust extraction. The slots are made with a depth of approximately 17 mm. Plastic pipes of 14 or 16 mm are placed in the slots. With main heating it is desirable to maintain a center to center distance of 10 - 12.5 cm. The pipes are fixed in bends so that they remain in place.

The pipes are connected to the distribution station that is placed in the room; a cabinet can be used for this if space permits. If there is no supply and discharge from the boiler, a plumber must prepare this. There must also be a power point at this location.

Don't have a plumber who can take care of this? Uipkes Wood Flooring is happy to help you with a plumber. The plumber will connect the distribution station to the supply and return of the heating boiler. The slots must be closed with an epoxy bonded agent before installing a wooden floor. To reduce consumption, this can be mixed with grinding dust or quartz sand.

Frequently Asked Questions

Can underfloor heating be milled into an existing sand-cement screed?

Yes, it is possible to mill underfloor heating into an existing sand-cement screed floor. This provides a good basis for installing underfloor heating systems.

Do the existing screed floors need to be removed before underfloor heating is milled into a sand-cement screed floor?

Removing the existing floor is not always necessary. If there is room to place the pipes directly in the new floor while pouring it, then that is an option. Otherwise, mill into the existing floor or remove the old sand-cement screed, then install underfloor heating and pour a new sand-cement screed over it with a drying time accelerator, so that you achieve a shorter lead time.

What are the costs of milling underfloor heating into a sand-cement screed?

For an area of approximately 50 m² you can count on a cost estimate of approximately €3150 incl. VAT for milling the underfloor heating , including installing the pipes, installing the distribution station, sealing the slots and connecting of the pipes at the distribution station.

How long does the entire process of installing underfloor heating in a new sand-cement screed floor take?

The total lead time for the complete package, including removing the existing floor, leveling the sand-cement screed, milling the underfloor heating and installing a new wooden floor, usually varies between 5 and 30 days. This depends on several factors, such as the size of the project and the drying time of the floor.
