Verified by manufacturer 9 months ago
Perforated engineering brick.
Application
Marshalls Engineering bricks comply and exceed the NHBC, Water Authorities, and Transport & Highways Agencies standards and specifications.
- Functional use when requirement for strength and low water porosity.
- Used above and below dpc.
- Used as detailing plinth brick.
- Out of ground facing brick replacement.
- They are suitable for use in sulphate soil conditions up to and including DS-1, DS-2 and DS-3.
Description
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 suitable for use below ground where natural sulphates, up to and exceeding Class 3 levels*, are present.
Features and benefits:
- Manufactured and tested in accordance with BS EN 771-3: 2011.
- High strength.
- Low absorption.
- Comply in all respects to the standards required by BS 5628: 2005.
