1.  The traffic on the Geoblock system rides on top of the structure’s cell walls,
protecting top soil from compaction and the vegetative root zone from
damage.
2.  That load is then distributed across the wide semi-riged paver unit.

The Presto Geoblock® system offers exceptional aesthetics, permeability, turf
protection and load support for pedestrian or vehicle traffic areas.
GEOBLOCK® Durable Grass Pavement Units Palletized and
delivered to site. Each pallet of light weight units represents 269 sq.ft.
Project specific guidance for the engineered base depth was provided by Presto
Products based on vehicle loading and usage considerations.

The Geoblock® system’s recommended engineered base is an
aggregate (70%)/topsoil (30%) mix, and provides 5-10 times faster
percolation and better storage capacity than typical road gravel.
The high performance aspect of the system reduces overall
installation costs by requiring far less depth of base than lighterweight or rolled pavement systems.
Small equipment and hand
tools were used to smooth
engineered base surface.
A string line and wood stakes were used
to keep Geoblock units aligned.
The GEOBLOCK units were laid out
in a bricklayer pattern.
The units were easy to cut
with standard equipment
where needed.
Mechanical reinforcement with screws provides additional
resistance to movement or damage from vehicle turning stresses
and torsional loads (typically only required around perimeter).
The GEOBLOCK® system maximizes load transfer and
distribution of wheel loads to 80,000 lbs. through large rigid
surface area and strong interlocking connections.

utilized for special event parking.

Design strong porous pavements that support H-20 loadings and
offer desirable aesthetics of green space.
Geoblock grass paving can help reduce land
space and costs associated with impervious
pavements by infiltrating stormwater and
reducing runoff.
Cooler pavements minimize the heat island effect.

Geoblock’s deep cells protect from
topsoil compaction and vegetative
damage caused by repeated
loadings.
The engineered base provides an excellent medium for healthy
roots, and grass grows faster reducing wait time to use pavement.
