Edging pavers are installed by excavating a trench, compacting a base, setting and anchoring the edging, then laying and compacting the pavers against it.
Getting edging pavers right is the difference between a lawn border that stays put for years and one that shifts with the first frost. The working method for installing edging pavers comes down to preparing a proper base, setting the restraint system flush to your line, and securing it before any paver touches the ground. Here’s the exact sequence, based on manufacturer installation guidance.
What You Need Before You Start
Edging systems fall into two camps: rigid plastic restraints with spikes or capture plates (used with permeable paver systems), and mortar or adhesive-style products for standard pavers. Both share the same foundation work.
For your base, plan to excavate to the depth your design calls for, plus roughly 6 inches beyond the paver edge. You’ll need:
- Geotextile fabric to separate soil from base stone
- Compacted base material (open-graded stone or similar)
- Edging restraint system with manufacturer-specified spikes or capture plates
- A plate compactor for proper settling
- Sand or bedding material for the pavers themselves
Setting the Edging: Step by Step
Start by establishing your elevation and perimeter line, then set the edging with the base side facing away from the pavement area. For permeable systems using geogrid, unfold the grid full length into the pavement area and connect edging sections with the included connectors.
Fill any gaps beneath the edging with base material so the restraint sits solid and level along the entire run. For curved installations, cut back the support and slit the grid in 12–18 inch increments perpendicular to the edging so it bends without buckling.
Secure the edging using the manufacturer’s anchoring method. In capture-plate systems, slide each plate under the edging base and geogrid, then fasten with two self-drilling stainless screws per plate. Tighten until the geogrid compresses. With spike systems, drive 3/8-inch spikes through the edging temporarily; these get removed once the pavers are laid and compacted.
Laying Pavers Against the Restraint
With the edging anchored, lay pavers starting from the restraint and working inward. Keep the first row tight against the edging base.
For long runs, stop paver installation about 6 feet from the far edge, locate and secure that second edge, then finish cutting and laying the remaining pavers. This prevents you from trapping yourself in cuts at the end of the project.
Once all pavers are placed, compact the entire surface with a plate compactor. For permeable systems, backfill adjacent material to about 1/2 to 3/4 inch below the paver surface. For standard edging, backfill with soil to the top of the pavement as soon as practical, then fine-grade with topsoil, mulch, or stone.
One caution: if you’re working with a permeable paver system, pedestrian areas need a 4-foot apron of geogrid, while vehicular areas need 6 feet. That extra fabric distributes the load and prevents edge settlement under weight.

Common Mistakes That Ruin an Edge
Most failed paver edges trace back to a handful of avoidable errors:
- Skipping base compaction. Uncompacted base settles later, dragging the edging down with it.
- Leaving wrinkles in the geogrid. Folds create voids that let pavers shift under load.
- Insufficient fabric overlap. Soil migrates through gaps and undermines the base.
- Delaying backfill. An exposed edge has no lateral support until backfill is in place.
- Ignoring the anchoring system. Omitting specified spikes, plates, or screws guarantees movement.
- Making radius cuts too wide. Tight curves need smaller, more frequent cuts to follow the line.
Manufacturer instructions vary by product, so always follow the specific guidance for your edging system. The installation sheets from Permaloc’s permeable pavement installation guide and SEK’s PermEdge specifier materials provide the detailed sequences for their respective systems.
FAQs
Do I need to remove grass before installing edging pavers?
Yes. Grass and its root layer must be excavated down to your design depth so the base material sits on stable soil. Leaving vegetation creates organic material that decomposes and settles, causing the edging to sink unevenly within the first season.
Can edging pavers be installed on a slope?
Yes, but the base preparation matters more. Step the excavation to follow the grade, compact each level thoroughly, and ensure the edging restraint maintains consistent elevation relative to the paver surface. On steeper slopes, additional anchoring with more spikes or plates per section helps resist lateral movement.
How long should edging mortar cure before compacting pavers?
The edging material needs to firm up enough to hold its shape under pressure, which typically takes several hours depending on temperature and humidity.
