This technical article provides additional guidance on concrete lintels faced with brick slips. It covers the following:
The industry is looking to alternative solutions to constructing traditional brick arch and soldier course detailing on steel lintels over external openings and has moved to using various products including the application of brick slips applied to concrete lintels.
The following identifies our warranty position and that unless sufficient proof of design and quality processes are in place, these products will not satisfy our standards.
These products may arrive on site in a multitude of shapes and sizes, with decorative slip facings adhered to a concrete lintel or cast into as part of the concrete lintel manufacturing process. The slips themselves can be cut from facing bricks or from other products, e.g., concrete bricks, artificial stone or even natural stone.
Some concrete lintel products use steel tangs, either flat plate or angles, projecting beyond the concrete component to act as the structural supporting mechanism – cast into the concrete backing.
These products are typically produced by a concrete lintel manufacturer or brick cutting companies – who either buy in the concrete lintels or manufacture them themselves and then adhere brick slips.
The lintels should be tested as a ‘whole product’ and not in isolation.
Evidence of design testing and quality management processes must be provided for the whole assembly.
Manufacturers of these products must be able to provide evidence to the warranty provider that their product meets one of the following options:
