Tarmac Truscreed Eco is a combination of natural hydraulic lime and sand which can be used as an alternative to a traditional cement levelling screed. Installed in conjunction with a breathable system, this creates a high-performance floor slab, enhanced by its flexural performance.
Suitable for use with underfloor heating Tarmac Truscreed Eco requires movement joints if used in large areas of screed with heating pipes.
Tarmac Truscreed Eco is used in internal situations, ideally suited for historic building renovation, to produce a floor ready to accept an appropriate final floor covering. It is breathable, behaves in harmony with other natural building materials such as timber. If the design allows, then water vapour can escape through the screed, helping to combat damage associated with damp upon permeable walls. Tarmac Truscreed Eco is suitable for use with breathable flooring finishes,those made from natural materials, beware of non-breathable adhesives.

Additional info
Benefits of Truscreed Eco include:
- Improved drying and shrinkage control.
- Fibre re-enforcement can be added to enhance performance without compromising the breathability of the lime screed.
- Factory mixing provides improved hydraulic lime dispersion, giving greater and more uniform performance throughout the floor area.
- Factory mixing takes quality control away from the site and into the factory, providing consistent quality materials and accurate proportioning.
- Delivered as a preblended dry mix that can be supplied to site in a bulk bag or for larger contracts, in state- of-the art silos with an integral mixing unit.
- Can be used for the repair of existing lime screeds.
