Concrete Floor Screed Depth

There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.

Concrete floor screed depth.

Screed is not concrete while the chemistry between the two isn t too dissimilar the concrete creation process is almost identical there are a few key differences that. Under this size we find it easier to just screed the floor by hand with the 2x4 screed. Screed is a thinner layer of concrete which s typically poured over a base floor to help form a smooth floor coating to provide a strong foundation for the top floor. If you are getting up to the 50mm you would question whether you want to use a smoothing product really just from an economic point of view because it is going to be very expensive.

Key steps to prevent floor screed issues. Screeds are covered by bs 8204 screeds bases and in situ floorings 2004. This method requires a minimum of 75mm coverage otherwise cracking will occur. Liquid screed is designed to cover up to 1000 square meters in one day compared to 150m in a traditional screed floor.

A screed is a layer of material laid in situ directly onto a base for one or more of the following purposes. For more information call us on 0207 538 2266. Substrates must be level with no pockets or high spots to ensure the thickness of the screed remains even. It may be applied onto either a solid in situ concrete ground floor slab or onto a precast concrete floor unit.

The maximum depth you would use a smoothing compound would generally be around out 10mm you can add aggregates to bulk up the screed going up to 30 40 50 mm. The screed is put on top of a separating membrane which will be applied on top of the layer of underfloor heating. As this type of screed is pumped it is usually delivered in a mixing lorry and put down via a pumping pipe.
