A 'self levelling screed' is a generic term given to a group of products which are used to create smooth floors prior to the installation of the floor covering. They are also known as thin screeds, flow screeds, liquid screeds, pumped screeds, deep bases or deep fills. They flow like liquid across substrates similar to ‘self levelling compounds’ but because they contain bigger aggregates they can be applied in higher depths, although the finish is not as smooth. In fact 'self levelling screeds' or ‘self levelling compounds’ do not naturally 'self level' but instead 'self smooth'. Over a large area for example the variance from one corner to another could be different but may not be apparent to the naked eye. They can be used to create 'level' floors through the use of a laser and level pins but it is not a wide spread practice. Self levelling screeds are usually used in flooring constructions to make up deficits in height or ensure the correct floor strength and load capacitiy.

UZIN's range of self levelling screeds have excellent flow characteristics, great strength as well as consistent and reliable drying. They are also pumpable and suitable for use with underfloor heating systems.
