Grasstone II Concrete Grass Pavers

Grasstone II 80MM Concrete Grass Pavers combine the strength of a concrete paver with the natural look of grass or decorative gravel. They are a great option for areas that need added stability without covering the entire surface with solid concrete.

Often searched for as grass pavers, turf pavers, concrete grid pavers, permeable driveway pavers, grass driveway blocks, open-cell concrete pavers, or concrete pavers with holes, Grasstone II uses large open sections that can be filled with planting soil and grass or with small decorative gravel.

The concrete grid helps support foot and vehicle traffic while reducing rutting, muddy areas, and soil movement. The open design also allows rainwater to drain through the surface instead of running off like it would from a fully paved area.

Grasstone II is a practical choice for residential driveways, parking pads, RV or trailer parking, overflow parking, walkways, side-yard access, drainage areas, and erosion-control projects. It can also be used for certain commercial, emergency-access, and green-paving applications when properly designed and installed.

The rectangular pavers can be installed in several layouts, including stacked bond, running bond, and herringbone patterns, giving you flexibility based on the look and use of your project.

Grasstone II performs best when installed over a solid, well-compacted base. The exact depth of your project may vary depending on your soil, drainage, and whether the area will be used for walking, parking, or occasional vehicle traffic.

1. Excavate the Area: Remove existing grass, roots, loose topsoil, and other organic material. For most patios, walkways, and pedestrian areas, plan to excavate approximately 7 to 8 inches. For driveways, parking pads, or areas that will receive occasional vehicle traffic, approximately 9 to 12 inches is a good starting point. This allows room for the approximately 3⅛-inch-thick 80MM Grasstone II paver, the bedding layer, and the compacted base beneath it.
2. Prepare the Ground: Grade the exposed soil so the area drains away from your home, garage, or other structures. Compact the soil until it feels firm and does not easily move underfoot. If your soil is especially soft, muddy, or unstable, adding landscape or geotextile fabric before the base material can help keep the stone from mixing into the soil below.
3. Build the Base: Add Yards Direct 3/4" Crushed Limestone to create a strong foundation. For walkways and other pedestrian areas, use approximately 3 to 4 inches of compacted base. For driveways, parking pads, and occasional vehicle traffic, use approximately 5 to 7 inches, depending on the condition of the soil below.
4. Add the limestone in layers about 2 to 3 inches deep and compact each layer thoroughly with a plate compactor before adding the next. A properly compacted base is one of the most important parts of preventing settling and uneven pavers later.
5. Avoid using rounded river rock as a base. Rounded stones move against one another instead of locking together like crushed limestone.
6. Add the Bedding Layer: Spread approximately 1 inch of Yards Direct Limestone Screenings over the compacted limestone base. Screed the screenings smooth and level to create an even surface for the Grasstone II pavers.
7. For projects where maximum drainage is the priority, a free-draining crushed-stone base may be used instead. Yards Direct 1/2" Minus Decomposed Granite can also be used for certain landscape and pedestrian applications where a compactable, natural-looking base or surrounding material is desired. The best base will depend on how much traffic the area receives and your drainage conditions.
8. Lay the Grasstone II Pavers: Place the pavers onto the prepared bedding layer in your desired pattern. Keep the units evenly aligned and check your progress regularly with a level or straightedge. Make adjustments as you go rather than waiting until the entire area has been installed.
9. Fill the Openings: For a grass-covered finish, fill the openings with a quality planting soil and add grass seed or sod plugs. For a gravel-filled appearance, use a small, free-draining decorative gravel that fits comfortably inside the openings. Yards Direct carries several gravel options that can be paired with Grasstone II depending on the look you want.
10. Finish and Compact: Once the pavers are installed, compact the finished surface carefully using equipment appropriate for concrete pavers. Refill any openings where soil or gravel settles during compaction. If you are growing grass through the pavers, water the area gently and keep the soil consistently moist while the grass becomes established.

Planning a driveway or parking area? Base preparation becomes especially important anywhere vehicles will travel or park. Heavier traffic, poor soil, drainage areas, steep slopes, fire lanes, or commercial applications may require a deeper base or project-specific installation requirements. For these applications, check with your contractor, engineer, or local permitting authority before installation.

Grasstone II is a great option for areas where you want the strength of a concrete paver while still allowing for drainage, grass growth, or a more natural-looking finish.

Common uses include:

• Grass driveways and residential parking pads
• RV, boat, and trailer parking areas
• Extra or overflow parking
• Walkways and garden paths
• Permeable patios and outdoor utility areas
• Side-yard and service access areas
• Areas where grass needs protection from occasional vehicle traffic
• Drainage areas, swales, and erosion-control projects
• Sloped areas that need added ground stabilization
• Decorative gravel-filled parking or walking surfaces
• Fire lanes and emergency access areas when properly designed and approved
• Commercial or larger green-paving projects

The open sections of Grasstone II can be filled with grass, planting soil, or decorative gravel depending on the look and function you want.

For a green finish, add quality soil and grass seed or sod plugs. For a lower-maintenance option, fill the openings with a small decorative gravel that allows water to drain through the surface. Yards Direct carries a variety of gravel options that can be paired with Grasstone II to create a finished look that matches the rest of your landscape.

For driveways, fire lanes, commercial parking areas, or other projects that will receive regular vehicle traffic, make sure the base and installation are designed for the expected load.

rasstone II is designed to be low maintenance, but a little routine care will help keep the surface looking good and draining properly over time.

Grass-Filled Areas: Mow the area just like a normal lawn and water, fertilize, and reseed as needed to keep the grass healthy. Try to keep soil and thatch from building up above the top of the concrete grid.

Gravel-Filled Areas: Check the openings occasionally and replace any decorative gravel that has been moved by vehicles, runoff, or regular use. Keeping the gravel near the proper level helps the Grasstone II units continue to support the surface evenly.

Keep Drainage Open: Remove leaves, mud, sediment, and other debris that may collect in the openings. Areas that receive a lot of runoff may need to be cleaned more often to maintain good drainage.

Control Weeds: Pull unwanted weeds as they appear or use a weed-control product that is safe for the surrounding grass, plants, and fill material.

Watch for Low or Uneven Areas: Periodically check for low spots, rocking pavers, or areas that have settled. Minor settling can sometimes be corrected by removing the affected pavers and restoring the bedding material underneath. Larger or recurring problems may indicate an issue with the compacted base.

Cleaning: Rinse the concrete with a garden hose as needed. For tougher dirt or stains, use a mild cleaner that is safe for concrete. Avoid aggressive pressure washing directly into the openings, which can wash away soil, grass, or decorative gravel.

What is Grasstone II?
Grasstone II is a precast concrete grid paver with large open sections that can be filled with grass, soil, or decorative gravel. It creates a strong, stable surface while allowing water to drain through the openings instead of covering the entire area with solid concrete.

What are concrete pavers with holes called?
Concrete pavers with openings are commonly called grass pavers, turf pavers, grid pavers, open-cell pavers, grass driveway blocks, or permeable concrete pavers. Grasstone II is a concrete grid paver designed for these types of projects.

Can grass grow through Grasstone II pavers?
Yes. The openings can be filled with planting soil and finished with grass seed or sod plugs. Once established, the grass grows through the openings while the surrounding concrete helps protect the ground from foot and vehicle traffic.

Can I fill Grasstone II with gravel instead of grass?
Yes. Grasstone II can also be filled with a small, free-draining decorative gravel for a lower-maintenance finish. Yards Direct carries several gravel options that can be paired with Grasstone II depending on the look you want.

Can Grasstone II be used for a driveway?
Yes, Grasstone II can be used for residential grass driveways, parking pads, and areas receiving occasional vehicle traffic when installed over a properly prepared and compacted base. The required base depth will depend on your soil conditions, drainage, and how often vehicles will use the area.

For areas receiving frequent heavy traffic or commercial use, additional base preparation or engineered installation requirements may be needed.

Is Grasstone II the same as Turfstone?
Grasstone II and Turfstone are similar styles of open-grid concrete pavers designed for grass, gravel, drainage, and ground-stabilization applications. They are not necessarily identical products, so dimensions, thickness, patterns, and manufacturer specifications may vary.

Customers looking for a Turfstone alternative may find Grasstone II suitable for many of the same types of projects.

Are Grasstone II pavers permeable?
The open-grid design allows rainwater to drain through the grass- or gravel-filled openings. How quickly the area drains will also depend on the bedding material, base, soil conditions, and how the project is installed.

Can Grasstone II help with muddy or rutted parking areas?
Yes. When installed over a properly prepared base, Grasstone II helps stabilize the ground and spread vehicle weight across a larger area. This can greatly reduce tire ruts, displaced soil, and muddy conditions compared with parking directly on grass or dirt.

Can Grasstone II be used for erosion control?
Yes. Grasstone II can be used in certain slopes, drainage areas, swales, and other locations where additional ground stabilization is needed. Projects with steep slopes, concentrated runoff, or significant drainage requirements should be reviewed by a qualified contractor, landscape professional, or engineer.

How thick is Grasstone II?
Grasstone II 80MM is approximately 3.15 inches thick, or just over 3⅛ inches.

How large is each Grasstone II paver?
Each Grasstone II 80MM paver measures approximately 23.62 inches long × 15.75 inches wide × 3.15 inches thick and covers approximately 2.6 square feet.

How much area does one pallet cover?
One pallet contains approximately 32 Grasstone II pavers and covers about 84 square feet.

For larger projects, it is a good idea to order a little extra material to account for cuts, layout adjustments, and possible jobsite damage.

What base should I use under Grasstone II?
For most residential installations, we recommend a properly compacted base of Yards Direct 3/4" Crushed Limestone with approximately 1 inch of Yards Direct Limestone Screenings used as the bedding layer.

The total base depth will depend on your soil and how the area will be used. Walkways and pedestrian areas generally require less base material than driveways or parking areas.

Can Grasstone II be installed directly over existing grass or dirt?
No. Grasstone II should not be placed directly over grass, topsoil, or loose dirt. The area should first be excavated and prepared with a properly compacted base. Skipping this step can lead to settling, rocking pavers, and an uneven finished surface.

Can I use decomposed granite with Grasstone II?
Yes, depending on the project. Yards Direct 1/2" Minus Decomposed Granite can be used around Grasstone II or in certain landscape and pedestrian applications where a compactable natural material is desired.

For the main structural base beneath Grasstone II, we generally recommend 3/4" Crushed Limestone because it provides a stronger compacted foundation.

Can Yards Direct deliver Grasstone II with the materials I need for installation?
Yes. Yards Direct can deliver Grasstone II along with available 3/4" Crushed Limestone, Limestone Screenings, planting soil, sand, decomposed granite, and decorative gravel, helping you get the pavers and supporting materials for your project in one coordinated delivery.
