Longcliffe Quarries launch LONGFLOOR liquid cement screed

Published:  22 January, 2019

Revolutionary fast drying floor screed solution for domestic, commercial and underfloor heating applications

Longcliffe Quarries are now supplying LONGFLOOR, a groundbreaking dry powder bulk binder for the manufacture of liquid cement screeds.

The LONGFLOOR liquid cement screed system has major advantages over both traditional screeds and anhydrite/gypsum flowing screeds.

LONGFLOOR can be laid at ten times the speed of traditional screeds, manual handling is avoided and a denser, more even surface and creamy smooth finish achieved.

LONGFLOOR dries at three times the speed of anhydrite/gypsum based flowing screeds. There is no laitance to sand off. Contamination and blistering issues with wet concrete or cement based floor adhesives are totally avoided.

This innovative product is not susceptible to cracking, crazing or curling and can be laid in wet areas. Applications include both domestic and commercial and provide good thermal conductivity over underfloor heating. It can be applied down to 25mm thickness in bays of up to 150m2. A single crew can lay 1000m2 in a day.

The binder consists of superfine high purity limestone powder plus a suite of dry chemical reagents and admixtures manufactured to BSEN 13813:2002. It is made in a new state of the art factory at the Longcliffe quarry near Matlock then delivered by Longcliffe tanker to a stockist’s silo where sand, cement, water and a liquid admixture are added.

Stockists are typically ready mixed concrete plants, mixer or dry leg. Delivery to customer can be from drum mix or volumetric trucks. LONGFLOOR liquid cement screed is discharged or more usually pumped in to the building, then simply dappled before applying LONGCURE, a sprayed proprietary curing agent.

Longcliffe Quarries are the UK’s largest independent producer of calcium carbonate, (limestone), powders, a company with a 90 year history of quarrying and grinding high purity Derbyshire limestone. As a result of a unique manufacturing process LONGFLOOR has a certified 95% recycled content.

Andy Littler, LONGFLOOR Director said: “We are very excited about this pioneering easy to use screed product. For many years the concrete industry has tried to develop a cement based liquid screed which flows well, dries quickly and is not prone to cracking. We have now achieved this. The screed industry is witnessing a sea change in favour of cement based liquid screeds and we intend to make LONGFLOOR the market leader and top performing benchmark standard”.

LONGFLOOR screed is currently available to screed contractors in the North West, Midlands, South East, London, South West, Humberside and Scotland. LONGFLOOR screed is being supplied on a daily basis in these areas with contracts up to 600m3 secured. We would welcome enquiries from additional stockists who would receive full technical and commercial support from the highly experienced Longfloor team.
