What happens to the bricks when a building is demolished? And to the pavers when paving is relaid? Reuse and recycling are the norm. Let us tell you about the many lives of our bricks and pavers.
Bricks get a second life
It’s not very often that someonechoosesto demolisha buildingbecause of the state of the brick façade.Especiallyif thefaçadeisa hundred years old. Often though, the old structure isnot quiteup to modern standards, and a renovation, either keeping or doing away with the old façade, is the better option.Even when a building is demolished,bricksdo not need to be wasted,and theycanbe reused or recycledafterdemolition.
Reuse old bricks for a new façade
Once themortar residueshave beenremoved, the brickscan be reused for restoration or new-build projects.In their second life,bricks canbe a real asset andthey givethe building an exceptionallook and character.
Recycling unused bricks
Bricksthat have neverbeenusedin abuilding, such as mis-fired bricks or offcuts, can becrushed tomakechamotte.This material can be used as a material intheproduction ofnew bricks.Even stones that have been used fordry-stackingsystemscanalso berecycledin this way.Masonry or bondedbricks cannotbe used for this purpose as theymay have mortar residuesthatcan cause lime pitting.
Recycling used brick
Bricks from waste sitescan bereusedafter recyclingfor jobs such as:
- Filler and stabilising material in infrastructure projects.
- Aggregate for poured and prefabricated concrete and mortar.
- Aggregate for bricks made from calcium silicate.
- Red‘crushed brick’as the surface for a tennis court.
- Plant substrates.
Asbricksare made entirely from natural raw materials, they do not have a negative impact on groundwater or surface water.
What about pavers?
Ourpavers can alsobe recycledandthisis typicallywhathappens to them.
Pavers have a long lifespan
International advisory and engineering firm RoyalHaskoningDHVhas determined thatpavers havean average lifespan of 135 years. Some 10% go on for 250 years.
Theyhavean overall reuse rateof no lessthan 90%
Theadvisory firmalso discovered that 90% of all pavers are reused, sometimes several times over.City authorities tend to reusebetween 80 and 90% of their used bricks for repaving or major maintenance. Pavers that aren't reused by that can be often find their way into private hands. This means that overall reuse of pavers is at least 90%.Sometimes they even get a third or fourth life in gardens, which is why they have such a high residual value.
Recyclingpavers
If a paver can no longer be reused,it can becrushed tiform chamotte. This materialis used in theproduction of new paversor forgranulate.The granulatecan be usedin road foundationsor as a substitute for gravel or sand or for adding to other construction materials.
