Floor Screed Minimum Thickness With Sbr

Bonded screeds are utilised where screed thickness cannot be built up or to minimise dead loads on structure.

Floor screed minimum thickness with sbr.

However bs 8204 1 emphasizes that there is a high risk of screed curling with unbonded and floating levelling screeds. Isocrete isopol sbr is used to produce polymer modified wearing screeds for heavy duty and industrial flooring and for rapid drying levelling screeds. Also where bonded screeds are installed as part of a flexible waterproofing system in combination with a flexible bonding agents. A minimum thickness of 65mm is possible provided the thermal insulation boards are firm enough for the compaction of the screed.

Sbr polymer modified screed includes a synthetic polymer resin to give increased toughness and bond properties. If we look at each different type you re going to have different floor screed thickness on the minimum and maximum depths. This screed provides high performance at thinner sections and is ideal when normal thickness cannot be achieved. The screed thickness should not be less than 50mm.

There are proprietary screeds available that can be laid at thinner depths than conventional sand and cement screeds. When bonding directly to the substrate with a bonding agent or a primer the minimum is 1 2mm feather edge with smoothing compound. Shrinkage and cracking is minimised permeability is reduced and flexural strength is improved. Bonded screed minimum depth.

As 3958 1 2007 a2 3 a nominates the minimum bonded screed thickness of 15mm at any isolated point. Therefore to allow for deviations in the finished levels the specified design thickness should be a minimum of 70mm.
