Alliance Gator USA
Gator Aqua Rock is a special line of permeable stone from Alliance Gator. This stone is calibrated by fractured high strength granite. Making it an ideal product for bedding and jointing material to collect water runoff.

Gator Aqua Rock

Permeable stone for permeable paver joints

graded ASTM no. 9 stone


The minimum slope of the soil subgrade should be 0.5%. Actual slope of soil subgrade will depend on the drainage design and exfiltration type. All drain pipes, observation wells, overflow pipes, geotextile and impermeable liner (if applicable) should be in place per the drawings prior to or during placement of the subbase and base, depending on their location. Care must be taken not to damage drain pipes during compaction and paving. No mud or sediment can be left on the base or bedding aggregates. If they are contaminated, they must be removed and replaced with clean materials.



  • Spread GATOR AQUA ROCK bedding material over base course. Bedding course should be 2″ (50 mm) of GATOR AQUA ROCK.
  • The surface tolerance of the screeded GATOR AQUA ROCK bedding layer shall be ±3/8 in (10 mm) over a 10 ft (3 m) straight edge.
  • Do not subject screeded bedding material to any pedestrian or vehicular traffic before paving unit installation begins.


  1. Lay the pavers in the selected pattern. Cut pavers and place along the edges, no piece should be smaller than 1/3 of a whole unit. To increase strength pattern in vehicular applications, we recommend laying the pattern in a 45-degrees-to-traffic flow.
  2. For applications such as driveways, we recommend that the edge restraints be installed with a ready mix concrete and reinforced with reinforcing steel.
  3. Sweep GATOR AQUA ROCK to fill joints.
  4. Remove excess GATOR AQUA ROCK on the surface by sweeping pavers clean.
  5. Compact and set the pavers into the bedding material using a low-amplitude, 75-90 Hz plate compactor capable of at least 4,000 lb (18 kN) centrifugal compaction force. This will require at least two passes with the plate compactor.
  6. After compaction ensure that the joints will be filled up-to 1/8″ (3 mm) from the top of the pavers and add or remove any excess of GATOR AQUA ROCK jointing material.

NOTE: The minimum slope of the finished pavement surface should be 1%. The surface of the pavers may be 1/8 to 1/4 in (3 to 6 mm) above the final elevations after compaction. This helps compensate for possible minor settling normal to pavement.
