BS 8204-1:2003+Amendment 1:2009 Screeds, bases and in situ floorings. Concrete bases and cementitious levelling screeds to receive floorings. Code of practice

BS 8204-1 gives recommendations for the design and laying of concrete bases and cementitious levelling screeds to receive in situ floorings. It also gives recommendations for constituent materials, design, work on site, inspection and testing of concrete bases that are to receive in situ wearing screeds.

BS 8204-1 covers the following types of materials:

a) Concrete (see BS 8204-2)
b) Polymer modified cement (see BS 8204-3)
c) Terrazzo (see BS 8204-4)
d) Mastic asphalt (see BS 8204-5)
e) Synthetic resin (see BS 8204-6)
f) Magnesium oxychloride
g) Pumpable self-smoothing screeds (see BS 8204-7)

BS 8204-1includes information on bases and levelling screeds that are to receive flexible floor coverings such as:
h) Textiles
i) Linoleum
j) Polyvinyl chloride
k) Rubber
l) Cork

It also includes rigid floorings such as:
m) Wood block and strip
n) Laminate floor coverings
o) Ceramic tiles
p) Natural stone.

BS 8204-1 applies to ground-supported and suspended concrete floor bases. It includes the use of concrete and levelling screeds made with lightweight aggregates conforming to BS EN 13055-1. Recommended methods for the assessment of levels and surface regularity and for the determination of in situ crushing resistance (soundness) are also given in this standard.

BS 8204-1 does not provide guidance on the structural design or related construction of concrete ground-supported floors or suspended slabs. Information on these aspects is given in BS 8110-1. The specification of concrete for base slabs is given in BS 8500-2. The recommendations in this code of practice relate to those other aspects of design and construction of concrete slabs that affect the performance of the overlying levelling or wearing screed.

This standard has been amended to include updates made to other cement and aggregate standards.
