Brick & Block Types

Ligna Group manufactures several different types/style of bricks and blocks. All are made from the same raw material. Most bricks and blocks are available in veneer, double brick (cavity brick or full brick wall) or single skin (single leaf) type construction.

These types/styles include:

Cobblestone Series: The Cobblestone series is our most popular style featuring a smooth curved face with a river stone/cobble stone appearance. These bricks and blocks can vary slightly in size; this variation is intentional and the mortar joints accommodate this variation by ranging 10mm to 20mm thick, but typically 15mm.

Sandstone Series features a smooth flat face like a diamond cut sandstone. This series comes in a range of sizes including a standard brick size. The mortar is 12mm thick, more formal in their thickness.

Super Insulating Series is the most recent innovation from Ligna Group. This Large block comes in single skin only, with an exceptionally high insulation. Total R value, as a result of the 110mm thick styrene centre and Ligna Stone outer layers, approximately R3.5. The mortar is 12mm thick.

The Super Insulating Series has the same finish as the Sandstone Series. This block comes with cavities for all types of services as well as cavities for structural reinforcement. It is also available in narrow veneer or internal brick counterpart.

For Information regarding specific sizes and specifications, please refer to the chart below.

The key to successfully building Timbercrete walls is to work to incremental benchmarks.

That is, both the horizontal and vertical courses need to be laid out in increments of "one block plus one mortar joint", as per the chart on the following page.

By strict observance of these increments, the finished wall aesthetics will be maximized, waste eliminated and cost minimised.

Mud Brick Series

Modelled on a traditional mud brick, the Ligna Stone mud brick series provides a more rustic version of the cobblestone finish. Lighter, robust and with superior insulation, it is a strong alternative to earth mud bricks. Mortar joints will vary from 10mm to 25mm depending upon the customers’ preferred module heights.
