Dismantling of bricks for reuse
- The type of brick and mortar: The features of the brick such as hardness effect on how easy the brick is to dismantle.
- Surroundings and space available for demolishing: Using big machinery such as an excavator requires space while dismantling the bricks by using hand tools doesn’t.
- Intended use of demolished bricks: For example, how intact the brick should be and what kind of durability is needed for the intended use
- Timetable: The dismantling method should be chosen within the timetable of the project as different methods can take different lengths of time.
Removing bricks one by one using a chipping hammer is slow but breaking the bricks is easier to avoid. Dismantling is done by drilling holes to the mortar joint surrounding the brick. Any leftover mortar is cleaned from the brick. This is done using a chisel.
An electronic saw can be used when knocking down a brick wall. Larger numbers of bricks comes off at once which makes the demolishing faster, but it is more likely that some of the bricks will break. The bricks are collected and mortar may be removed by using a chisel. With this method collecting bricks is slower compared to when the dismantling is done by using a chipping hammer.
Demolished bricks should be piled up on pallets and secured with strong plastic wrap or straps to keep the bricks from falling. Brick pallets are moved by using a forklift and transport to the storage or straight to the intended reuse location. Bricks should be stored in a sheltered place protected from water and temperature fluctuations as these might harm the bricks.

 About CIRCuIT
The Circular Economy wiki is supported by the Circular Construction in Regenerative Cities (CIRCuIT) project, which is funded by the European Union's Horizon 2020 research and innovation programme. CIRCuIT is a collaborative project involving 31 ambitious partners across the entire built environment chain in Copenhagen, Hamburg, Helsinki Region and Greater London. Through a series of demonstrations, case studies, events and dissemination activities, the project will showcase how circular construction practices can be scaled and replicated across Europe to enable sustainable building in cities and the transition to a circular economy on a wider scale.
