How to Install a Paver Patio Base

Paver patio base panels are made from lightweight high-density polypropylene. The panels typically have tongue-and-groove or shiplap edges to keep the panel edges flush with one another. You may wonder how a thin plastic mat can effectively replace a 6-in.-deep layer of compacted gravel. The answer is that the panels spread out the load, so the weight of a person walking on the patio is distributed more widely. Distributing the load puts less pressure on the soil and prevents the paver bricks from becoming uneven.

The panels have the added advantage of providing an insulating layer that reduces problems caused by soil that thaws and refreezes. And finally, paver patio base panels have built-in channels and holes to drain water to the sand layer below. Studies from independent engineers have concluded that the panels are equivalent to a compacted gravel base for load distribution and superior for thermal resistance.

Benefits of a Paver Patio Base:

• Requires less digging
• Eliminates heavy gravel fill
• Saves time
• Reduces the cost of digging and hauling
• Prevents damage to the landscaping caused by excavating equipment
• Allows patio installations in fenced areas or areas with limited access
• Protects the screeded sand while you’re installing pavers

Plan the Paver Area

• Plan the size and mark out the area with paint, a garden hose or string.
• Measure the width and length and figure out how much material you’ll need.
• Divide the square footage of your patio by the square-foot coverage of each panel to determine the number of panels you’ll need. Add about 20 percent if your patio is an irregular shape.
  • Pro tip: Plan to build the patio base 1 foot wider and longer than the size of the finished patio so that it will extend 6 inches beyond the paving on all sides.
