Longcliffe Quarries is 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. It can be laid at 10 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 is 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.
