In this part of the area 'exposed masonry' we explain the attaching of our wire trellises in clinker brickwork, particularly on historic buildings from c. 1870 or freestanding walls. You will find information about this building material and the mounting options below including sample photos of attached trellises. Another note: Modern brick facades are often not solid brick but rather 'EWIS' or "closers." Please check back with us if necessary.
Clinker Bricks are so named due to the metallic sound they make when struck together and come in a deep red, black, purple and yellow. They are produced from clay that is fired at extremely high temperatures, sintering the surface to form its characteristically shiny coating –sintering is a process of forming a solid mass with pressure or in this case heat, without reaching the point of liquefaction, making them water-resistant and more durable than the traditional red brick.The transition to historic bricks is fluid, often only using loam rather than high-quality clay, and fired at far lower temperatures, resulting in a more porous product that often needs a protective plaster layer against long term weathering.
Solid clinker bricks can be found on many historical facades but today they are almost exclusively used as paving stones. At times one sees clinkers as the facade to newly built houses, walls etc. but appear mostly as hollow bricks with rectangular holes in them.
Our kits can be installed into both the bricks and mortar joints. All 5 construction methods are suitable with their standard mounts, both for hollow and solid clinkers. Our heavy kits should be paired with a composite mesh sleeve if installing into hollow clinkers. We recommend hammer drill bit HB 44444, with heavy and massive kits HB 16210 ; alternatively percussion drill bits and universal drill bits can also be used.
It is important to note that decorative bands or single decorative bricks should not be drilled into! The grid of where you will lay your wire rope trellis should be pre-planned in accordance to the walls surface. When drilling directly into solid clinker masonry, you can hit extremely hard sinter spots, which appear from the caking of ferric oxides and other minerals. If this happens you will need a hammer drill. Refer to our advice given under 'drilling' if necessary.
