Engineering Bricks are durable, high strength bricks, specially manufactured to accommodate high loads and cope with exposure to aggressive ground conditions.
Made from selected dense aggregates and a choice of cements, the bricks, which exhibit low porosity and high dimensional accuracy, are completely frost resistant and suitable for use below ground where natural sulphates, up to and exceeding Class 3 levels*, are present.
(*see durability information on datasheet.)
Engineering Bricks are manufactured and tested in accordance with BS EN 771-3: 2011; Specification for Masonry Units: Aggregate Concrete Masonry Units and meet the criteria for strength, durability and sulphate resistance as detailed in BS 5628 Pt 3: 2005 and PD 6697 and other Standards.
Marshalls Engineering bricks comply and exceed the NHBC, Water Authorities, and Transport & Highways Agencies standards and specifications.
