Frequently Asked Questions

What depth base course does Grasspave2 require?

The depth of base course required is entirely dependent on the application. It is crucial that our Technical Specifications are referenced, and municipalities consulted for areas such as fire lanes, as these requirements vary. Overall, a general guideline would be an equivalent depth to the requirements for 2” of asphalt. See our Base Course Depth Recommendations chart for a reference – though all depths must be verified by an engineer and if applicable, the fire department.
