Chippage on the edges and corners of square edge pavers in segmental paving installations is an all-too-frequent occurrence. Chippage occurs when the pavers are allowed to move (rotate) against each other. This is due to failure to properly compact the base and setting bed, to properly space the pavers and to properly fill (and maintain) the joints with jointing sand. Design manuals typically call for 1/16" to 1/8" spacing between the paver units. Thus, the oft-used terms "hand tight" and "butt joint" are misnomers.
Chamfered and lugged pavers were developed to eliminate these chippage problems – chamfers keep the edges and corners from coming into contact and lugs create the needed spacing or separation to accommodate jointing sand. It's the spacing and jointing sand that develops the "interlock" mechanism, which allows segmental paving systems to function.
Some landscape architects, building owners and home owners prefer the aesthetic appearance of chamfered pavers, while others prefer the look of square edge pavers. Yet, no one willingly accepts the unsightly chippage that oft time develops. Endicott Clay Products Co. has addressed this issue with the development of our unique Paver Spacers. They create and assure the needed spacing between units (to accommodate jointing sand), yet allow the crisp appearance of square edge pavers.
PAVER SPACERS are available in two styles: 'T' Spacers and '+' Spacers
Proper Paver Spacer usage ensures a tight, chip-resistant fit.
