The ECOSCREED products are supplied in 25kg bagged format stacked 50 bags per pallet. They can be supplied in either a fully blended for continuous type of mixer pumps or format or with the binder bagged and glass bagged separately.
The products are generally mixed using a Putzmeister SP11 DQR that we can supply to the job complete with operator. We can supply a team of 3 to load the mixer and lay the screed or the client can provide the labour for this part of the work themselves to reduce costs.
For example, to produce the Ecoscreed Alpha ST the mixing hopper will take 3 bags of binder mixed with 6 bags of recycled glass and 30 litres of water to make a suitable flowing screed.
The Ecoscreed Alpha TF will take 4 bags of binder with 6 bags of recycled glass and 40 litres of water
3. Floor Preparation
It is critical that no flowing screed is allowed to track down underneath the insulation either at the perimeter edge detail or through penetrations through the insulation.
Where foil backed insulation is used this must be covered by a 500 gauge polythene and the pipework clipped down through the polythene into the insulation.
The insulation should be taped at the joins and a 10mm expansion strip installed around the perimeter edge detail and any up stands or columns within the area to be screeded.
Joints should be installed where there are changes in UFH zones. All UFH pipework should be properly clipped down with sufficient clips to prevent the pipes rising when the screed is poured over them.
The mixer pump eg.Putzmeister SP11 DQR then mixes and pumps the material through a 50mm pressure hose to the floor and point of application.
Small levelling indicators are spread around the room on approximately a 1.5 metre grid pattern and are then laser levelled to the correct finished floor screed level required.
There should always be at least 25mm cover to the uppermost surface of the UFH pipework.
Once the levelling tripods have been removed the screed is dappled in two perpendicular directions using a deep dappling motion on the first direction followed by a light more rapid dapple in the second direction.
The final floor is left smooth and flat and can be walked on after 24 hours
