Precast concrete, acid etched

Product description
This precast concrete uses the highest quality white cement and aggregate giving excellent surface definition, minimal colouring and fantastic performance. However, these premium ingredients do lead to increased cost.
An acid etching process exposes the fine aggregate, homogenizing the surface and removing any defects introduced during the forming process. However this textured surface more readily holds dirt, which can also be more difficult to clean, though not to the same degree as a sand blasted finish.
Massive structural and complex geometric forms, only limited by the transportation infrastructure, can be achieved by architectural precast concretes. They are very heavy but highly durable.
Concrete is not recyclable but downcycling is possible.

Intended applications
• External envelope
• Structural elements
