Porous Paving for Green Infrastructure Design

Porous paving is a green infrastructure solution for commercial developments and private residences. Permeable paving incorporates products that improve runoff infiltration. Unlike concrete and asphalt, porous paving products absorb runoff while also stabilizing driveways, parking lots and fire lanes.

GEOBLOCK® Grass Pavers

Grass porous paving system
Intended for occasional-use porous pavements
Two options: GEOBLOCK® and GEOBLOCK® 5150

Benefits

High flexural strength
Load transfer and distribution for HS25 loadings
Resistance to torsional stress
5-10x better percolation than competing rolled permeable pavements

Applications

Emergency lanes
Utility access lanes
Overflow parking
Road shoulders
Pedestrian trails
Golf cart pathways
Greenways

The durable and porous GEOBLOCK® grass pavers offer superior load distribution, improved turf protection plus high resistance to torsional stress.

Install GEOBLOCK® grass pavers on an engineered base of of aggregate (70%) and top soil (30%) for best performance and maximum stormwater infiltration. Base depth will vary depending on the application but on average the GEOBLOCK® permeable pavers require 2-3x less depth than competing rolled products. The rigid paver walls create a strong system that can accept loads immediately which makes installations faster and easier.

GEOBLOCK® permeable pavers lay flat and contour to the landscape. Connect the panels with with the built-in tabs to create an interlocked porous paving system. Fill the grass pavers with topsoil and vegetation (either see or sod).

GEOPAVE® Aggregate Porous Paving System

Gravel filled permeable pavers
Herringbone design and open-graded system
Intended for normal use traffic

Benefits

HS25 Load Rating with minimal base
Larger panel units results in improved load distribution
Resistant to breakage from vehicle turning
Integral bottom mesh to keep infill in place
Add snap delineators in yellow or blue

Applications

Emergency access lanes
Parking lots
Trails and walkways
Driveways
Shoulders and medians

Designed for everyday traffic, the GEOPAVE® gravel porous pavement system promotes stormwater infiltration, manages runoff, and creates water storage.

The GEOPAVE® system’s highly permeable aggregate infill limits runoff as its herringbone construction and integrated mesh bottom keeps aggregate in place. This prevents lifting which can compromise the stability of the porous paving system.

Install GEOPAVE® gravel pavers on an aggregate base of 4-6 inches and connect the panels using U-Clips. Similar to the GEOBLOCK® grass pavers, GEOPAVE® panels ship flat in panels and lie flat on the ground for easy shipping, unloading and handling.

GEOWEB® Geocell System

Cellular confinement system
Stabilizes aggregate or aggregate/topsoil mix for economical permeable paving system
Load support over weak soils

Benefits

Decreased rolling resistance
Rutting control for unpaved surfaces
Reduced maintenance
Economical alternative to asphalt and concrete pavements

Applications

Laydown yards
Intermodal/port facilities
Boat ramps and heavy vehicle pads
Driveways
Trails and walkways

A geocell is a three-dimensional cellular structure that promotes stability and positive drainage, two critical goals for porous paving.

GEOWEB® geocells are manufactured from virgin high density polyethylene (HDPE). Virgin HDPE is strong, durable, and flexible which makes it an excellent material for load support.

The perforated honeycomb cells can be filled with a variety of infill materials including crushed stone, top soil, sandy soil, concrete, and gravel. Confined infill controls shearing and movement. The filled system distributes surface pressure, controls rutting and reduces long-term maintenance.

When rain and runoff infiltrate the ground, the infill absorbs the water which drains through the cell’s pores and reduces stormwater runoff.

GEOWEB® geocells are shipped as collapsed panels and expand like an accordion. The expanded panels are secured in place with ATRA® anchors or ATRA® stakes.

When installing GEOWEB for porous paving applications, we typically recommend GW30V. Contact our sales team for project specific recommendations.

PaveDrain is a permeable articulated concrete block (P-ACB), not a permeable paver. Each concrete block as an arched storage chamber that allows you to retain almost an inch of stormwater per block.

What separates PaveDrain from traditional permeable pavers is the seams. A permeable paver has aggregate filled joints that allows the pavers to connect to create a paved system. PaveDrain’s joints are left open in order to allow maximum stormwater infiltration.

PaveDrain blocks are placed by hand or machine. The blocks interlock with each other to create a porous paving system that pavers, drains and stores.

The PaveDrain blocks are offered in gray, charcoal, tan, rose and brown.

PaveDrain® should be checked bi-monthly, ideally during a rain event in order to ensure there is proper infiltration. A visual inspection of the joints will reveal whether they are clogged with sediment or debris.

The best way to clean your PaveDrain® system is to use a PaveDrain VAC Head with a combination truck or a commercial vacuum truck. These methods result in the most thorough removal of sediment and debris. For smaller installations or residential applications, PaveDrain® joints can be cleaned with a commercial shop vacuums that is approved for sediment removal.

Additionally, you can stick a ruler between PaveDrain’s joints to determine how much sediment in in the storage chamber. If the ruler is unable to go more than 2″ deep, it is time to clean the porous paving system.

Each block weighs approximately 50 pounds
