Application

Gypsol Summit; a multi-purpose screeding solution designed for use in high-rise applications above ten stories.


To use Gypsol Summit in highrise buildings, ensure that the pump is suitable for the application, e.g., a multi-cylinder piston pump. Besides its particular use for tall constructions, this liquid screed is also suitable for the encapsulation of an underfloor heating system, either electric or warm water. Furthermore, it can be used to produce a smooth, flat, and level floor to form the sub-base for subsequent floor coverings. It is especially suitable for internal floors in hospitals, schools, offices, apartment schemes, and other constructions.


LKAB Minerals advise hiring specially trained screeders to pump the screed into place. They will use specialized equipment. In conclusion, Gypsol Summit will provide a cost-effective and environmentally friendly alternative to cement-based screeds.

Description

Gypsol Summit is designed specifically for use in high rise applications where the screed needs to be pumped to ten storeys and above.


Gypsol Binder is an integral component of Gypsol Summit, a liquid screed suitable for use in all construction types

including a steel frame, concrete frame, lightweight

steel, and traditional masonry construction. It is

suitable for residential and commercial properties,

Gypsol Summit can be used to improve the acoustic performance of a floor to meet or exceed

Part E of building regulations. Gypsol Summit has been specially formulated to allow pumping to high levels over 10 stories.
