Technical Attributes

All clay and concrete pavers are produced to function primarily as hard wearing surfaces.

Clay Paver Attributes

Pavers are produced in different formats and thicknesses. Typically thinner pavers (50mm or less) are more suitable for low trafficked applications such as domestic driveways, walkways and pedestrian pavements. Corobrik produces clay pavers in compliance with SABS classifications as defined below:

SABS Brick Classification

  1. PA - CLAY PAVERS (1:1, 2:1 or 3:1)
    Clay pavers that are selected or produced for their durability and for a high degree of uniformity in size and shape, and that have dimensions such that the ratio of work size length to work size is approximately 1:1, 2:1 or 3:1.
  2. PB - CLAY PAVERS
    Clay pavers that are selected or produced for their durability and for their uniformity in size and shape.

For achieving paved surfaces appropriate for the traffic/loads to be accommodated, the Clay Brick Association of South Africa has two technical handbooks – Flexible Segmental Clay Paving and Rigid Segmental Clay Paving. These should be referenced when choosing products:

Concrete Paver Attributes

Corobrik concrete pavers are produced to SABS specifications. Please reference the different product brochures to the relevant SABS specification for concrete paving that define the base/sub-base specification requirements for different load/traffic applications.

SANS 1058 Classification Concrete Block Pavers

There are three classifications, type S-A and type S-B for interlocking pavers and classification S-C for non-interlocking pavers.

Block Type S-A allows geometrical interlock between all faces of adjacent blocks. When layered together, these blocks resist the spread of joints by their plan geometry. Generally, these blocks can be laid in herringbone pattern parallel to both longditudinal and transverse axes of the joints. Block type S-A is used in roads and heavy duty pavements.

Block Type S-B allows geometrical interlock between some faces of adjacent blocks which, when keyed together, resist the spread of joints parallel to the longditudinal axes of the blocks.

Block Type S-C allows no geometrical interlocking between adjacent faces and relies on its dimensional accuracy and the accurancy of laying to develop interlock.

Class

There are two classes ie: two compressive strengths are specified:

Class 25 has an average compressive strength of at least 25MPa. Class 25 blocks are typically specified for most uses.

Class 35 has an average compressive strength of at least 35MPa and should be specified where exceptional loads may be encountered.
