Gator Base Landscaping Foundation

Gator Base is made by a Canadian company Alliance.  They have developed a product that replaces up to 6-inches of landscape foundations.  It makes foundations stronger because of better load transfer, it speeds up installation time and allows for interlock to be installed in small areas machines can’t reach. 

Gator Base Advantages Over Traditional Aggregate

Gator Base replaces 6 inches of crushed stone interlock foundation


Larger surface area distributes weight and has better load transfer

Faster installations – less aggregate being transported to the installation area, and less tamping is required


Gator Base is designed to handle Ottawa’s freezing and thawing without damage to your landscape foundation.

Perfect for projects where access for machinery is limited like between houses or in other tight spaces.

Gator Base is engineered to last and still backed by A&Z Interlock’s amazing warranty.

Check out this Gator Base explainer video and see how the technology works.

How To Install Gator Base

Step 1


Our crew digs a foundation to a depth of 6”.   Foundations that use crushed stone have an excavated average depth of 6-12”.  Since a single layer of Gator Base replaces 6” of stone our foundation is at the maximum recommended depth.

Step 2

Levelling & Compacting Sub Grade

We compact the base layer of soil and slope it away from any structures like a  house. The area needs to be as smooth as possible and relative to the final grade and slope of the area.  

Step 3

Adding Geofabric & Levelling Bedding Sand

We lay down non-woven Gator Fabric and cover the excavated and tamped area.  Then we add a ¾” layer of sand and level it using a float.

Step 4

Installation of Gator Base

In a staggered pattern, we lay out the Gator Base over the desired project area.  Using the tongue and groove system the base is secure and locked into place. The surface area of the Gator Base ends up being 6” wider than the final paved area.  Any curved and excess Gator Base can be trimmed using a utility knife.

Step 5

Lay Pavers &
Install Gator Edging

We lay the pavers on the Gator Base foundation in the pattern the customer wants.  Then we install Gator Edge with butterflying anchor screws. We securely fasten the Gator Base to the ground maximizing lateral support.  This prevents sunken pavers and keeps your patio looking good for years to come!

Step 6

Gator Maxx Polymeric Sand

Every project uses polymeric sand to prevent weeds from growing between the pavers.  Gator Base has developed a new product that is technologically advanced and stronger than other products.  We sweep the sand in the joints of the Ottawa interlock then use a machine to level and compact the joints.

Step 7

Hardening Polymeric Sand

The last step is to mist the polymeric sand.  By adding water it triggers a chemical reaction hardening the paver joints as it dries.   Your project is ready to enjoy.
