ASTM C936 Interlocking Pavers and What the Spec Changes on Site

ASTM C936 is the interlocking concrete paver spec, not a brand name. It sets strength, absorption, and dimensional rules so a driveway unit is not a patio tile wearing a driveway costume.

PaverForge Hardscapes specs C936 units where the field takes cars. Call 727-490-9798.

What the spec changes in the hole

A C936 driveway paver is typically 80mm for passenger vehicles. It interlocks. The joint transfers load. A 60mm patio unit on a thin sand bed will rock, then rut, then need a re-level. We will not sell that as a driveway because it was cheaper on the pallet.

  • C936 interlocking units under tires

  • Compacted aggregate base sized to the load

  • Joint sand that can lock and be maintained

  • Edge restraint so the field does not creep

Ask the contractor to name the spec

If a quote only names a color, ask whether the unit is a C936 interlocking paver and how thick it is. Then ask what they will compact and where the water goes. Those three answers separate a field that lasts from one that looks finished on day one.
