From its Hermitage Quarry in Maidstone and its Depot in Ashford, Gallagher is able to supply its range of Gallaflo flowing screeds.
Gallaflo is Gallagher’s range of high quality self compacting cement based liquid screeds for use in domestic and commercial projects. It complies with BS EN 13813.
Gallaflo is a cost effective alternative to traditional sand cement screeds. It can be laid as thinly as 25mm, and with high thermal conductivity it lends itself perfectly to underfloor heating areas. It is easy to install, quick drying and can be walked on in just 24 hours.
Gallaflo self compacting flowing screed is made to exacting standards by quality assured manufacturers to BS EN 13813:2002. It is a combination of high quality Cemfloor binder, specially selected sands, water and special additives where required. It is designed to offer a smooth flat and level surface for use in the vast majority of interior non wearing applications where a subsequent floor covering is to be used. Gallaflo screed is perfectly suited for use in floating, bonded or unbonded construction and can easily incorporate electric or warm water underfloor heating systems.
Gallaflo screeds should be used in accordance with BS8204-7:2003 ‘Code of Practice for Pumpable Self-Smoothing Screeds’. To ensure a high quality screed, it is recommended that application is carried out by a specialist screeding contractor who has completed the necessary training.
HEALTH AND SAFETY DATA
Gallaflo screeds are delivered to site ready to use via offsite mixing plants, removing the need for labour intensive site mixing and associated mixing equipment.
Gallaflo screeds are pumped directly to where they are needed, removing much of the manual handling required to install other screeds. Gallaflo screeds are generally pumped using equipment with closed or grilled dispensing hoppers, removing risk of contact with moving machinery.
Gallaflo screeds are finished using a lightweight dappling bar requiring no secondary compaction, thus removing most of the physical work needed to lay other screeds. This significantly reduces the negative impact on the musculo-skeletal system of
