Engineering bricks can be used for damp-proof courses. [1] Clay engineering bricks are defined in § 6.4.51 of British Standard BS ISO 6707-1;2014 (buildings & civil engineering works - vocabulary - general terms) as "fire-clay brick that has a dense and strong semi-vitreous body and which conforms to defined limits for water absorption and ...
A metal damp proof course (DPC) between the stone foundation and brick wall. Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
An example of a damp proof course of slate in a brick wall intended to prevent rising damp. A physical damp proof course made from plastic can be installed into an existing building by cutting into short sections of the mortar course, and installing short sections of the damp proof course material.
One of many methods of resisting such ingresses of water is to construct the wall with several low courses of dense engineering bricks such as Staffordshire blue bricks. This method of damp proofing appears as a distinctive navy blue band running around the circumference of a building. It is only partially effective, as in spite of the lower ...
The purpose of a Vertical Damp Proof Barrier is to prevent the ingress of damp and water into subterranean structures such as basements, cellars, tunnels and earth shielded buildings. (Also known as Earth sheltered buildings ).
Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp , and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an ...
Remember that a course (in context of building) is a single row of bricks and adjacent mortar. A damproof course is where the mortar course is partly or wholly replaced by some matter that resists water movement. Damp-proofing (in the context of building) is something entirely different. I could go on with many examples but suffice to provide 2.
Bricks may decay due to crystallization of salts on the brick or in its pores, from frost action and from acidic gases. [ 45 ] Bricks are laid in courses bonded with mortar, a combination of Portland cement, lime and sand. [ 46 ]
