Description
This screed is still made using just cement, aggregate (generally Washed Grit) and water but with the additional of Polypropylene fibres used to control initial cracking. They are not used for structural purposes.
These screeds can delivered directly to your site address on one of quality tipper trucks.
Sand & Cement screeds should only be used as a levelling screed, i.e. as a base for tiles, vinyl, timber flooring etc.
They are ‘semi-dry’ in order to control shrinkage and need a significant amount of work when laying in order to compact them properly. A minimum thickness of 25 mm is required for a fully bonded screed, 50mm for an un-bonded screed and 65mm for a floating screed (i.e. on top of insulation boards). 75mm is the minimum in a commercial environment for a floating screed.
Bonded – screed laid onto a mechanically prepared substrate with the intention of maximising potential bond between screed and substrate.
Un-bonded – screed intentionally separated from the substrate by the use of a membrane.
Floating – screed laid on insulation boards either acoustic or thermal. This is also a type of un-bonded screed.
Very thick sections may need to be laid in more than one layer.
