Important Design and
Construction Aspects to Consider

Compaction

Containment

Drainage
Compaction
Sand-set, segmental clay paver
installations rely on adequately
compacted base material to support
the pavement under load


Compact bases and sub-bases with
appropriately sized equipment
Include compaction testing in specifications
Containment
Segmental clay paver installations must be
adequately contained to prevent the movement
and shifting of pavers under load


Review anticipated paver traffic and specify appropriate
edge restraints

Plastic edge restraints

Steel or aluminum edge restraints

Set in place concrete or stone edging

Poured in place concrete curbing
Asphalt is not a appropriate edge restraint for vehicular
clay pavements
Drainage
Appropriately specified clay pavers are very durable in
freezing climates; poor drainage contributes to
premature deterioration of paver systems and
efflorescence


Slopes of 2-10% minimize standing water and yet are
gradual enough to minimize joint sand loss
Consider base and sub-base material and local conditions;
incorporate drainage into installation specifications
Paver Maintenance & Cleaning






Consult the paver manufacturer before using cleaners or
sealers
Use gently flowing water and a stiff bristle brush to
remove dirt
Commercial cleaning agents specifically formulated for
clay pavers are available for tough stains
Avoid removing joint sand while cleaning; replace joint
sand as necessary
Rock salt and other ice melts will not harm clay pavers;
their use may contribute to efflorescence
Remove snow with rotary brooms when possible; snow
plows and blowers with rubber edges are best; do not use
ice scrapers
Long Term Value




Clay pavers are very durable
When installed over a sand setting bed and compacted
aggregate base, clay paver systems allow easy access to
underground utilities with limited disruption to adjacent areas
Clay pavers are easily recycled into new paving projects; the
antiqued aesthetic of reclaimed clay pavers is often highly
desirable
Clay pavers will not fade over time; the color specified today will
be the color enjoyed in the future

LEED Considerations

Credits SS 6.1 and 6.2 Stormwater Design: Quality Control
Permeable clay pavers reduce runoff and increase on-site infiltration.

Credit SS 7.1 Heat Island Effect Non-roof
Many clay pavers have a Solar Reflectance Index of 29 or greater.

Credits MR 4.1 and 4.2 Recycled Content: 10 and 20%
Whitacre Greer pavers have a post-consumer recycled content
of up to 6.25% depending on color.
Multi-shade Permeable Boardwalk Pavers are produced with 100%
pre-consumer recycled material.

Credit MR 5.1 and 5.2 Regional Materials: 10 and 20% Extracted,
Processed & Manufactured Locally
The shales and fireclays used in the manufacture of Whitacre Greer
pavers are mined in Northeastern Ohio near Alliance, OH and within
a 500-mile radius of many major metropolitan areas.

An
engineer should be consulted for hydrology and load
bearing design considerations
Situations where permeable paver systems should not exfiltrate:
When
distance between permeable pavement and water supply
wells, streams and wetlands is less than 100 feet horizontally
When
depth from bottom of pavement base is less than 2 feet
from water supply
When
When
used directly over solid rock
used in areas were large quantities of contaminants can
directly impact the sub grade or aquifers, such as at gas stations
