Gator Aqua Rock – 50 lb Bag

Rapid stormwater drainage and structural interlocking support define Gator Aqua Rock, engineered to meet strict ASTM No. 9 standards for permeable paver installations across southern New England. This high-strength, fractured granite aggregate provides the ideal bedding course and jointing material, locking pavers firmly in place while allowing heavy surface water runoff to filter away instantly. Designed to withstand regional freeze-thaw cycles, it ensures long-term stability for eco-friendly hardscapes.

Key Features & Benefits

• ASTM No. 9 Compliance: Precision-graded crushed granite that adheres strictly to national engineering standards for permeable paver joints and bedding courses.

• Fractured Granite Composition: Angular, high-strength stone edges lock together tightly to prevent paver shifting, rutting, or surface displacement under traffic.

• High-Void Drainage Design: Maximizes void space between aggregate particles to facilitate rapid water infiltration and prevent localized pooling.

• Manageable Packaging: Supplied in a convenient 50-pound bag for efficient job-site handling, clean pouring, and precise distribution.

• Structural Durability: Resists breakdown, crushing, and weathering under continuous compaction.

Ideal Applications

• Permeable concrete paver patios and outdoor living spaces in East Greenwich

• Eco-friendly residential driveways and parking aprons across Rhode Island

• Slip-resistant pool decks and backyard courtyards

• Commercial pedestrian plazas requiring stormwater management compliance

• Sustainable municipal walkways and public green spaces

Frequently Asked Questions

What is the coverage rate per 50-pound bag?

Each 50-pound bag covers approximately 20 to 25 square feet of paver surface area, depending on joint width and bedding depth requirements.

How do I calculate the total number of bags needed for my project?

Calculate your total project square footage, then divide by 20 to 25. We recommend ordering an extra 5% to 10% to account for material handling and sweeping waste.

Can polymeric sand be used instead of Gator Aqua Rock?

No. Permeable paver systems require an open-graded stone like Aqua Rock in the joints rather than polymeric sand to allow rainwater to drain freely into the sub-base.

What are the pickup and delivery policies?

Bags can be loaded directly into your vehicle at our Watson Materials supply yard located at 1500 South County Trail in East Greenwich, RI, or added to larger material orders for job-site delivery across Rhode Island. Deliveries are typically completed within a week unless backordered.

Pro Contractor Tip

When installing permeable paver joints, sweep Gator Aqua Rock diagonally across the surface until joints are completely filled, then compact the pavement using a rubber-pad vibratory plate compactor to seat the stones without fracturing the aggregate. Refill joints as needed and sweep clean before final inspection.
