Absolute Scapes – Exposed Aggregate Perth | Why Is it So Popular?
Another reason for the ban on Absolute Scapes – Exposed Aggregate Perth mill waste and other natural wood products is the potential for exposure to lead and other metals. This can happen through fires, building work, and improper handling of the materials. As a result, these materials are not allowed to be placed in masonry structures. Materials that have been exposed and treated will generally have a somewhat higher moisture content than other materials. In general, exposed aggregate should be treated to add moisture resistance. The use of sodic resins will help with this problem because they prevent the wood fibers from absorbing moisture.

To reduce the risk of expansion and contraction, treatment is often added at the manufacturing plant, where the aggregate is made. At the mill, the materials may also undergo some type of treatment, to improve their ability to resist moisture. Exposure is not the only way that materials can be damaged. Another common cause of damage is the hydrostatic pressure, which occurs when pressure is applied to the material over a prolonged period of time. Hydrostatic pressure can occur during transportation or during manufacturing processes and can include both solids and liquids.
Hydrostatic pressure can cause expansion or contraction, causing fractures or cracks to develop. Commonly known as sheet crack, sheet crack is an example of exposed aggregate being damaged and then forced out of its grain.
