20mm Blue Metal Sydney & Queensland It offers excellent compaction properties20mm blue metal aggregate is a slightly larger version of the 10mm variety. It is used in applications that require better drainage, such as retaining walls, drainage trenches, and larger concrete slabs. The 20mm size is excellent for projects requiring robust structural support, as the larger stones provide superior load bearing capacity. Like its smaller counterpart, this aggregate is produced from crushed basalt rock and retains the same strength
