Sand and Cement Screed
Ready-to-use cement & sand screed is an ideal screed for flooring and roofing applications. It can be used as ground floor slabs (floating foundations), used on suspended floors, as a topping to lightweight screeds based on perlite or other lightweight aggregates and can also be used as a floating construction over insulation to give acoustic or thermal properties.
Features:
Retarded in order to remain workable for 8-12 hours
Consistent quality is guaranteed
Better cement dispersion gives greater and more uniform compressive strength throughout the floor area
Pre-mixed provides consistent quality materials and accurate proportioning
Fibre reinforcement is often added to the mix instead of using wire reinforcement, which guarantees an even distribution throughout the total thickness of the screed.

Fibre Screed
Fibre screed has been developed to meet the increasing demand for factory-mixed cement:sand screeds of all mix designs incorporating an even dispersion of polypropylene fibres. The presence of suitable fibres can help to give a more cohesive mix and help control cracking caused by intrinsic stresses.
Applications: Fibre screeds are ideally suitable for use in hospitals, offices, superstores, industrial and other applications where there would be a high cost in loss of use through floor failure due to surface cracking of screed. Ideally compatible for use with underfloor heating systems.

Features and advantages of sand screeds over traditional cement:
-
Minimum early age shrinkage/cracking
- Improved flexural strength/flexural fatigue resistance
- On many occasions can eliminate the use for wire mesh
- Improved toughness
- Easy to place, compact and overcomes many practical problems when used as an alternative to steel crack control fabric
- Fibres cannot be misplaced
- Better impact/abrasion resistance against site traffic
- Factory mixed to give accurate control and better dispersion of cement and fibres with minimum compressive strengths as specified in BS 4721/4
