Groundsmart 4 Roman Brick Rubber Landscape Edging 6pk: A Practical Guide (2026)

Updated November 2026

Groundsmart 4 Roman brick rubber landscape edging 6pk is a flexible, lightweight border system that gives a lawn or bed a crisp, finished edge without concrete or mortar. This guide walks you through planning the run, setting the sections, and anchoring them so the border stays straight through freezing, mowing and heavy rain.

Plan the Layout and Gather Supplies

Start by marking the path of the border with a garden hose or spray paint. Curves look best when they are smooth arcs rather than tight bends, so lay the hose out and step back to check the flow from the house or sidewalk. Measure the total run and divide by the length of each section to estimate how many pieces you need, then add one or two extra for cuts and mistakes.

Gather the tools before you dig:

• Spade or half-moon edger for the trench
• Garden hose or marking paint
• Tape measure and a line level
• Rubber mallet
• Landscape stakes or spikes (the included anchors work for most soils)
• Hand saw or utility knife for trimming sections
• Coarse sand or crushed stone for the base in soft or sloped ground

Dig the Trench to the Correct Depth

Cut a trench along your marked line so the top of the edging sits flush with, or slightly above, the surrounding grass. Most installers dig about the height of the edging plus 1 to 2 inches for a sand base. Keep the trench sides as vertical as you can, since a clean cut helps the edging sit upright. Remove sod, roots and rocks as you go, and tamp the bottom firmly.

Set and Anchor the Sections

Lay each section into the trench, pressing the interlocking ends together so there are no visible gaps. Check the top edge with your line level or a straightedge every few feet, and adjust the depth where the ground dips or rises. Drive the stakes through the pre-drilled holes at roughly 12 to 18 inches apart on straight runs, and place a stake within a few inches of every joint. Tap the top of the edging gently with the rubber mallet to seat it, and backfill the outside edge with soil or mulch so the border does not lean.

Cutting and Fitting Corners

For tight curves, make shallow cuts with a hand saw on the inside edge only, then flex the piece into place. Overlap the cut piece slightly onto the next section so the joint stays tight. Always wear eye protection when cutting rubber, because small chips can fly.

Finish the Border and Check for Problems

Once every section is anchored, walk the full length and look for lifted corners, uneven tops or gaps at joints. Re-seat any piece that has shifted and add a stake where the border flexes. Rake soil or mulch against the outside edge to hide the stakes and give the bed a natural look. Water the area lightly to settle the backfill, then check again after the first heavy rain.

Common Mistakes

• Skipping the sand base in soft ground, which lets the edging sink unevenly over time
• Placing stakes too far apart on curves, causing the border to bow outward
• Setting the top too low, so the mower wheels ride over the edge
• Failing to check level before anchoring, which shows up as wavy lines later
• Cutting pieces without measuring the joint, leaving gaps that collect weeds

Recommended Gear

A sturdy half-moon edger makes trenching along a marked line far easier than a square spade, especially in compacted soil. View on Amazon

A rubber mallet with a non-marring head lets you seat each section without cracking the edging or leaving dents on the top surface. View on Amazon

A line level clips onto a string line and shows height differences across a long run, which helps keep the top edge consistent. View on Amazon

FAQ

Can I install this edging in winter?

It is best to install when the ground is workable and not frozen, because frozen soil makes trenching difficult and can heave the sections later. Mild days above freezing usually work well if the soil is not saturated.

How deep should the stakes go?

Drive the stakes so their heads sit flush with or just below the top of the edging, which keeps them out of the way of the mower. In hard or rocky soil, pre-drill with a long screwdriver or rod before driving.

Will the edging hold up to a lawn mower?

Properly anchored rubber edging is designed to take light contact from a mower wheel without moving. Keep the top set level with or slightly above the grass so the wheel rides on the lawn rather than the border.

Conclusion

With a level trench, a firm base and stakes placed close enough to hold each curve, groundsmart 4 roman brick rubber landscape edging 6pk gives a clean, durable border in a single weekend. Take your time with layout and depth, since those two steps decide how straight the finished line will look. Check the border after the first few weeks and re-seat any section that has shifted.
