Double sided block with a natural weathered finish and a completely vertical face.

Features and benefits:

  • A free-standing, self-supporting, mortarless wall which is fast and simple to install. It can also be finished as a ‘stop end’ wall. AG provide stop end blocks and factory split half blocks to achieve this.
  • The double-sided finish of each block means that the walling can be built anywhere without the hassle of a concrete foundation.
  • It is suitable for both straight and fixed radius curved walls. To build a straight wall, just alternate the blocks (short-side, long-side, short-side and so on). To create a curved wall, use the same block length for each course (either the short or the long edge).
  • Has the natural appearance of cut stone - attractive, durable and versatile.
  • Built with no mortar or concrete, this dry-build locking system allows fast-track construction in all weathers - offering quicker installation rates than traditional brick and blockwork.
  • Can be installed by a competent DIYer or a tradesman but does not require the skills of an experienced brick layer.
  • Can easily be built up to 900 mm high with no concrete or mortar.
  • Each block features a locator that acts as a guide to ensure accurate vertical alignment and a perfect running bond.
  • The ShortCut™ cap block is shaped asymmetrically (tapered), making capping straight or curved walls much easier. Installation of the capping block will be easier and quicker as the shape of the capping piece minimizes the need for cuts.

Minimum radius:

  • Outside curve (to back of block on bottom course): 2.56 m.
  • Inside curve (to back of block on bottom course): 2.04 m.
