Installation Instructions:

Step 1

STEP 1 • Excavation of the New Gator Base Area

Total excavation will be done as follows – Total depth will be determined by adding together the following elements’ depths: Geofabric, compacted bedding sand’s final height (1/2 in [13 mm]), Gator base (3/4 in [19 mm ]), and paver’s height. • Total excavation should be 6 in (15 cm) wider on each side than the final paved area. This excavation could be done using a shovel or small mini-excavator, which can easily go through narrow passages. • Prior to excavating, check with local utility services to ensure digging does not damage underground pipes or wires.

STEP 2 • Levelling and Compacting of the Base

A • Once excavation is completed, level the excavated area using a rake or shovel. • Ensure a slope of at least 1 degree away from any structure, such as a house.
B • The native soil needs to be prepared and compacted in the same way that one would prepare a traditional base installation, using a hand tamper or plate compactor. • This area should be as smooth as possible to get rid of high or low spots within about 3/8 in (10 mm). • Using a string level (stakes and a string line), tie the string to the stakes to establish level according to which the final slope will be measured (minimum of 1 degree to the desired final paver level). • Once the final level is achieved, proceed to step 3.

STEP 3 • Addition of Geo-Fabric and Compacted Bedding Sand

A • Lay down the geo-fabric and cover the complete excavated area.
B • Spread an even layer of sand to a depth of 3/4 in (19 mm) over the geo-fabric. • To obtain a perfect 3/4-in (19 mm) bedding layer, use two 3/4-in (19 mm) pipes with an equal distance of 4 to 6 ft (1.22 to 1.83 m) over the geo-fabric and fill the surrounding area with sand. Using a straight board, level the bedding sand relatively to the pipes. • When removing the pipes, fill in the empty gaps. • Remember that levelling and compacting the bedding sand will be the last step prior to installing the Gator base.
C • Using a hand compactor and/or plate compactor, compact the 3/4 in (19 mm) of bedding sand until you obtain a final height of ½ in (13 mm) of compacted bedding sand. The final area should be smooth.

STEP 4 • Installation of the Gator Base

Make sure to install the Gator Base on the extended excavation area (total excavation should be 6 in [15 cm] wider on each side than the final paved area). • Start laying the Gator Base units according to a staggered pattern while ensuring locking of the tongue & groove system. This will guarantee the panels’ stability when the pavers or slabs are laid down. • Trim any visible curves or protruding angles using a utility knife.

STEP 5 • Installation of Pavers and Gator Edge.

It is recommended to create a path with pieces of plywood in order to avoid displacing or damaging the Gator Base. • Lay the pavers directly onto the Gator Base according to the selected pattern. • (Adding a second layer 1/2 in (13 mm) of loose bedding sand on top of the Gator Base is also an accepted method of installation.) • Use a rubber mallet to adjust the pavers. • Make sure the Gator base is 6 in (15 cm) wider on each side than the paved surface. Install Gator Edge on the Gator Base, making sure that it rests firmly against the pavers. A nail will be driven into every second hole to maximize lateral support of the Gator Edge.

STEP 6 • Sweeping, Compacting and Blowing of the Gator Maxx Polymeric Sand

A • WWhen emptying the bag of polymeric sand, spread it onto the dry, paved surface. This will avoid separation and sweeping a mountain of sand. • When sweeping the polymeric sand, spread over a small area before moving onto the next, while making sure to fill in the joints.
B • It is now time to compact the sand into the joints using a hand tamper or plate compactor. Do not use a plate compactor over slabs. Repeat filling and compacting of the paver joints. Finally, sweep the surface with a fine bristle broom and remove all excess sand. • Ensure the sand is 1/8 in (3 mm) lower than the paver chamfers.
C • Finally, use a blower to blow off all sand residue laying on the paved surface. • The combined actions of the sweeping and blowing will help eliminate any hazing effect. • Avoid callbacks! • Alliance Gator is the only manufacturer that offers a 10-year limited warranty on all its polymeric sand.

STEP 7 • Watering and Blowing Action

The watering process will activate the polymeric sand’s bonding process, and the sand will harden when dry.
A • Set your water spray to “mist,” and from a height of 4 ft (1.22 m), spray the paved surface for 10 to 15 seconds then wait 3 to 4 minutes. (N.B. Ensure the paved surface does not dry between waterings)
B • From a height of 2 to 4 ft (0.60 to 1.22 m), mist and rinse the paved surface and wait 3 to 4 minutes before repeating the mist-and-rinse process for a third and final time. However, stop misting (ALERT) when you see a minimal amount of water retention on the paver joints. • If the work is being done on a hot summer day, avoid spraying large areas, as they will dry up faster.
C • Finally, use a blower to remove any excess water lying on the paved surface. Again, this process eliminates any potential hazing effect. • Carefully following these installation steps guarantees elimination of any callbacks, and increases referrals.
