Think Green

Architects and engineers, planners and developers are thinking “green”; designing and building eco-friendly, energy-efficient, high-performing, sustainable, and water conserving buildings and surroundings with features that promote natural over chemical, recycled over new, and renewable over expendable. While the initial cost to “go green” may be initially higher than using more conventional building methods and materials, the payback in energy efficiency, water conservation, and even worker productivity easily exceeds those higher initial costs.

Specifications

Product Specifications

CSI Section 02795 — Porous Paving

Material

Minimum 97% post-consumer recycled, reinforced High Density Polyethylene (HDPE). Maximum 3% UV stabilization and coloring. The HDPE is sourced from recovered post-consumer plastic waste ("regrind"), diverting it from landfills and repurposing it into a high-performance structural paving product.

Dimensions & Weight

Length19‑3/4" (50 cm)
Width15‑1/4" (39 cm)
Height1‑3/4" (4.5 cm)
Coverage2.14 sq ft per panel (5 panels = 1 m²)
Weight2.4 lbs per panel
ColorBlack

Cell Design

Hexagonal cells, each 2‑1/8" × 2‑3/8" with a 1‑5/16" base opening and 1/2" perimeter openings providing both horizontal and vertical drainage. Cell wall and base thickness: 1/8" — strength comes from the geometric design, not from fill material.

  • 93% open area at top of cell
  • 46% open area at bottom of cell
  • Stabilizing cleats built in — no pinning or stapling required

Load Specifications

Heavy Load Application

H10 to H20 — 16 to 32 Kip Axle Loads

Designed for fire lanes, emergency vehicle access, utility vehicle access, and overflow parking with heavy commercial or municipal traffic.

Sub-Base Build-Up (top to bottom):

  1. GRASSY PAVERS™ panel (1.75" height)
  2. Sandy loam topsoil fill or crushed stone
  3. Leveling layer: angular sand or sandy loam (1.5")
  4. Gravel/Sand or Class 2 Road Base (2"–8")
    75% (¾"–¼") gravel + 25% sand, compacted to 95% Modified Proctor
  5. Existing soil sub-base: CBR ≥ 3

Note: Base depth varies with loading requirements, frequency, and subsoil conditions. Consult a site engineer for high-traffic applications.

Light Load Application

Pedestrian, Nature Trails, Green Spaces, Handicap Access

Ideal for walkways, recreational trails, garden paths, ADA-accessible routes, beach access, and areas with foot traffic or light vehicle use.

Grass Fill Application:

  1. GRASSY PAVERS™ panel (1.75")
  2. Sandy loam topsoil fill
  3. Bedding layer: angular sand or sandy loam (1.5")
  4. Existing soil base: CBR ≥ 3

Stone Fill Application:

  1. GRASSY PAVERS™ panel (1.75")
  2. 3/8" diameter gravel, crushed limestone, or crushed brick
  3. Bedding layer: angular sand or sandy loam (1.5", optional)
  4. Existing soil base: CBR ≥ 3, depth 2"–8"

Stormwater Management Performance

With 93% open area at the top of the cell and 46% open at the bottom, GRASSY PAVERS™ deliver industry-leading stormwater percolation performance. The porous paving system provides a complete stormwater management solution that satisfies EPA requirements and local municipal stormwater ordinances without costly drainage infrastructure.

Percolation Rate

Up to 8 inches per hour with turf fill. Over 10 inches per hour with aggregate fill. Rates increase further as base depth increases.

Runoff Coefficient

Tested runoff coefficient of only 1.2% at 3 inches/hour rainfall. Traditional solid paving has a minimum runoff coefficient of 95%+ regardless of rainfall amount.

Groundwater Recharge

Stormwater percolates immediately into the aquifer through the porous paver design, providing direct, immediate groundwater recharge at the point of precipitation.

No Retention Ponds

Eliminates the need for retention ponds, drainage systems, and filtering systems in most applications — saving significant land area, construction cost, and ongoing maintenance expense.

The most direct method of stormwater management: a known percentage of void space with compacted aggregate and a known percolation rate from the existing subsoil allow retention and dispersion rates to be easily calculated and documented for permit compliance. GRASSY PAVERS™ are a recognized stormwater Best Management Practice (BMP) and are valuable for use in sensitive wetlands and ecologically volatile systems.

ADA Compliance — ASTM F 1951‑99

GRASSY PAVERS™ surpass the performance requirements of ASTM F 1951‑99, the standard specification for accessibility surfaces under the Americans with Disabilities Act (ADA). The ASTM standard measures the work required to propel a wheelchair across a surface — both in a straight line and while turning — using a calibrated force wheel on a rehabilitation wheelchair. To comply, the Work Ratio must be less than 1.00 (i.e., easier than propelling up a 1:14 slope ramp).

TURF FILL — Straight

0.351

Work Ratio (must be < 1.00)

TURF FILL — Turning

0.532

Work Ratio (must be < 1.00)

AGGREGATE FILL — Straight

0.340

Work Ratio (must be < 1.00)

AGGREGATE FILL — Turning

0.501

Work Ratio (must be < 1.00)

Testing confirmed that soil, sand, turf, aggregate, wood chips, or crushed rubber fill all meet the ASTM F 1951‑99 ADA accessibility criteria when used with GRASSY PAVERS™.

Installation Guidelines

Architectural Specifications — Materials & Installation

Materials (in order of installation)

  1. Porous Road Base (required for heavy traffic — fire lanes, etc.) — Sandy gravel mixture; washed masonry sand component; aggregate not to exceed ¾" diameter. Depth determined by site engineer.
  2. Bedding Layer — Washed masonry sand, 1–1.5" depth. Optional when using aggregate fill.
  3. GRASSY PAVERS™ Panel — 97% recycled HDPE, honeycomb cell design, UV stabilized. 15‑1/4" × 19‑3/4" × 1‑3/4", 2.14 sf, 2.40 lbs, Black.
  4. Fill Material (Grass) — Sandy loam topsoil (60/40 mix) or topsoil typical of locality as approved by architect.
  5. Fill Material (Aggregate) — 3/16" minus crushed stone to 3/8" is ideal; washed pea gravel is a good alternative.

Installation Procedure

  1. Excavate site allowing for thickness of all materials.
  2. Grade subsoil and compact.
  3. If required, install porous road base material and compact to standards determined by site engineer.
  4. Install sand bedding layer on top of subsoil or road base. Compact and level. (Optional with aggregate fill.)
  5. Install GRASSY PAVERS™ over bedding layer using a bricklayer's staggered-joint pattern. Cut panels with a hand saw or reciprocating saw to fit curves, edges, trees, curbs, and lane markers.
  6. Grass fill: Fill cells with topsoil mixture level with top of paver (do not overfill). Water thoroughly, reapply topsoil to low spots, then apply grass seed evenly. For sod, leave cell depth for sod thickness (e.g., 1/2" for 1/2" sod). Roll or press sod into place with turf roller and saturate with water.
  7. Aggregate fill: Fill cells to top and compact with vibratory plate.

Snow plow areas: set blade height at 2" above paver surface. Maintain grass installations with normal turf care — irrigate, fertilize, and mow as needed.
