Kiln Dried Paving Jointing Sand

A pavement does not solely consist of bricks or blocks. It is a system, created by various components. Importantly, these components work together to create interlock between pavers, in order to spread the load exerted onto them.

The Foundation, Bedding Sand, And Jointing Material Are Just As Important As The Pavers Used To Create The Pavement, In Achieving Structural Interlock.

Bedding Sand


The bedding sand used above the foundation, but under the pavers; needs to be moist (when installed), well-draining, hard, and angular. The sand particles need to range between 0.150mm and 5mm in size.

Jointing (Grouting) Material


The paving jointing (grouting) material used to fill the joints between pavers, needs to be hard; angular; and consist of particles between 2mm and 0.150mm in size.

Foundation Material


The same base material used under asphalt (tarmac) roads is used as the foundation material under Interlocking Concrete Pavement Systems.

Why Use Kiln Dried Paving Jointing Sand Between Pavers?

South Africa does not have a standard for paving jointing sand. Generally, plaster sand is used in South African paving installations. The problem with plaster sand is, it usually contains clay. Clay is not angular and hard (as prescribed above), it’s rather a soft with round particles. This means that clay tends to insufficiently fill paving joints, by creating ‘bridges’ that collapse when the ‘moisty’ clay particles dry. Furthermore, clay is known to stain pavers. As a result, plaster sand isn’t the ideal material to use for jointing pavers. After tending to countless site complaints, where plaster sand has been used as jointing sand; Cretesol has invested in researching and sourcing paving jointing sand that complies with ASTM C144, the American Standard for Paving Jointing Material.

Cretesol’s Kiln Dried Paving Jointing Sand

The Paving Jointing Sand that Cretesol supplies is a specially graded, kiln dried silica sand that flows seamlessly into paving joints, filling them much more effectively (compared to what plaster sand does), and creating superb interlock between the pavers.

Cretesol’s Kiln Dried Paving Jointing Sand is packaged for ease of storage, handling, and transportation; in 40kg bags.

SmartStone and Bosun, specialist paving manufacturers, have approved of and recommend the use of this jointing sand on both Residential and Commercial applications.

Re-jointing, Re-Sanding, and Maintaining Paving Joints

SANS 1200MJ, the South African Standard for the Installation of Segmental Paving, specifies that paving joints should be filled a few weeks subsequent to installation and again periodically, in order to ensure the joints, remain full.
