This traditional screed mix is made up from sand and cement at a 1 3 5 ratio and is then spread onto the floor and allowed to solidify around the ufh pipes or cables.

Floor screed min thickness.

35mm to 45mm total depth of screed inclusive of pipe dependant on product chosen. Therefore cement sand screed is used for leveling of floors in buildings where design of the supporting slab is designed for a payload of 300 to 400 kg m. There are proprietary screeds available that can be laid at thinner depths than conventional sand and cement screeds. What is the minimum thickness a floor screed can be.

However bs 8204 1 emphasizes that there is a high risk of screed curling with unbonded and floating levelling screeds. Installed on a separating membrane e g. However bs 8204 1 emphasises that there is a high risk of screed curling with unbonded and floating levelling screeds. Installed on and bonded to a set and hardened base.
