Concrete Grid Pavement
T-10.2
Note: This BMP Fact Sheet is a supplement to Fact Sheet T-10, Permeable Pavement Systems. It
is not intended to be a standalone document.
Description
Concrete grid pavement is one of several
different types of permeable pavement
systems described in Volume 3. Previous
versions of the manual referred to this
pavement as modular block pavement.
This pavement consists of concrete block
units with large openings (at least 20% of
the total surface area) that are filled with
free draining material. Figure CGP-1
provides a pavement section.
Site Selection
Concrete grid pavement is appropriate for
areas with low traffic volume and lower
vehicle speeds. Applications include:
Photograph CGP-1. Concrete grid pavement installation in a parking
area. The concrete segments along the perimeter of this installation
showed wear that could have been mitigated with a concrete perimeter
barrier.
• Overflow parking areas,
• Access/maintenance roads,
• Emergency vehicle and fire access lanes, and
• Equipment storage
areas.
See additional details on
Fact Sheet T-10.
