Longfloor

Longfloor is a dry powder bulk binder for the manufacture of a Cement Based Liquid Screed to a specification BS EN 13813:2002. Liquid screeds are also referred to as self-levelling or flowing. The binder is delivered in bulk powder tankers for storage in a silo. They are typically manufactured in specialist screed and mortar or ready mixed concrete batching plants, either through a pan mixer or batched straight in to a lorry mounted rotating drum mixer.

Longfloor binder consists principally of very fine high purity ground limestone, (calcium carbonate) powder plus a suite of dry chemical reagents and admixtures. The limestone powder assists flow and has cementitious properties which reduces the amount of cement required.

Other reagents and admixtures reduce water demand, assist flow and act to counter bleeding and shrinkage.

Longfloor binder is added to a fine aggregate, cement and water and delivered by concrete mixer truck from a stockists plant. Further liquid flow or retarder admixtures may also be added prior to placing.

Longfloor binder is manufactured by Longcliffe Quarries Ltd, a company with a 90 year history of quarrying and processing the exceptionally chemically pure Bee Low limestone in the White Peak area of Derbyshire.

The company’s main business is supplying ground calcium carbonates to the animal feeds, glass manufacturing and sealants and adhesives industries. A family owned independent company, it is the second largest industrial grade limestone powder manufacturer and supplier in the UK.

Liquid Cement Screed
Liquid floor screed is an essential flooring component that is laid on top of concrete and provides a smooth, sturdy and level surface area as a base for the final floor covering. With its free-flowing consistency, liquid floor screed achieves a flawless finish underneath ceramic tiles, linoleums, vinyl and all types of wooden and carpet floors while offering adequate support to endure traffic.
It is ideal for domestic, commercial, and industrial projects and can be supplied as a C20 or C25mm/N2 compressive strength product.
