Fibre Reinforced Screed

Conventional fibre screeds are suitable for use with all wet underfloor heating systems and meet the increasing demands of sites for sand/cement leveling screeds that incorporate an even dispersion of polypropylene fibres throughout the mix. The presence of fibres helps to achieve a more cohesive screed material helping control cracking caused by intrinsic stresses.

Fibre screeds are ideally suited for use in residential dwellings, apartment complexes, offices, retail stores and industrial applications where a high cost in loss could potentially occur through floor failure due to surface cracking of the floor screed.

Polypropylene fibres are added to the sand/cement mix either at batching plant and transported directly to site via tipper wagon or mixed within in a screed pump vessel located in situ on site.

Product Compatibility

✓ Suitable for underfloor heating systems
✓ Directly to concrete ground floor slabs
✓ Installed to insulation boards
✓ Used with precast concrete units or beams
✓ To acoustic insulation systems

Benefits

✓ Impact and abrasion resistance
✓ Reduced risk of shrinking and cracking
✓ Improved flexural strength
✓ Improved toughness
✓ Reduced permeability

Reinforcement & Strength

Polypropylene fibres help to achieve a more cohesive screeding material – ultimately reducing the risk of early shrinkage and cracking. By incorporating fibres within the mix a three-dimensional system of secondary crack control reinforcement can be considered as a cost-effective alternative to steel wire fabric traditionally introduced of this purpose.

Drying Times

It is advisable to allow one month per 25mm of thickness up to 50mm thickness thereafter the screed dries at half the rate. A thorough process is in place to ascertain project requirements and by correctly specifying a site appropriate floor screed great care is taken so as not to delay the ultimate delivery of a project. High humidity or low ambient temperatures can delay the drying out process, we ensure the correct floor screed type is specified at quotation stage.

Deliveries

Ready-mixed bulk loads in tipper road trucks generally up to 10-20 tonnes. For smaller deliveries or to suit specific access requirements, screed deliveries can also be supplied in bulk bags.

Site mixed sand loads are delivered in tipper wagons or via bulk bags for smaller applications. Cement deliveries where possible are despatched to site via moffett wagon allowing cement to be easily positioned at mixing areas with minimal disruption to the site.

Characteristics

Fibre screed characteristic’s include improved flexural fatigue and strength resistance coupled with improved pumping ability. Improved toughness with reduced permeability providing better impact and abrasion against site traffic.
