SNAP-IT is a modular plastic formwork system for creating permanent concrete garden edges. It replaces timber boxing and traditional shaping methods with a faster, cleaner, and DIY-friendly solution. Once poured, the concrete cures in place and the plastic can be trimmed flush.
All SNAP-IT components are made from durable, UV-resistant polymer. They’re built to stay in the ground and hold their shape for good. The plastic becomes part of the structure and is not removed.
SNAP-IT is faster to install, doesn’t rot or warp, and requires no ongoing maintenance. Unlike timber or steel, it stays in place and becomes part of the structure, giving you a long-term, professional finish without contractor costs.
Use the SNAP-IT Builder (coming soon!) to plan your layout and calculate how many straights, curves, and elbows you’ll need. Or choose a pre-made kit that suits your project size and shape.
Not at all. The SNAP-IT Builder (coming soon!) is a free, web-based tool that helps you plan and calculate your project. You can use it on your phone, tablet, or computer, no downloads or design experience required.
Yes. Use 90° or 45° Elbow Connectors for clean corners, or Landscape Curve Units for smooth transitions. Bending the plastic is not recommended, each component is designed to hold its shape.
Yes. SNAP-IT is perfect for retrofitting around established trees, garden beds, and lawns. Use our SNAP-IT Builder (coming soon!) to plan your shape, then simply dig around the area and install SNAP-IT in sections.
You’ll need a spade, snips (for trimming components), steel rebar (included in most kits), a hammer or mallet, and a SNAP-IT Finishing Trowel (included in most kits or sold separately). A string line or chalk is helpful for layout.
Yes, all units can be trimmed with snips for smaller spaces. Always leave a 10–20mm overlap between pieces for strength and a snug seal.
In most cases, a shallow trench helps with levelling and keeping your layout stable during the pour. Dig to about the depth of the SNAP-IT channel and line with bedding sand if needed.
Yes. A 6mm steel rod (or 2 rods for heavy-duty installs) must be laid inside the SNAP-IT channel before pouring concrete. Use Lock Pins to hold it in place.
Because SNAP-IT is modular, you can easily reposition or replace components before pouring. If your concrete is already poured, fixing the edge may require trimming or removing the section and repouring.
A standard DIY mix works well:
For smaller jobs, one 40kg bag of instant concrete will fill about 2.1m of SNAP-IT edging.
Yes. You can mix oxides into your concrete to create coloured edging. Add the oxide when mixing your concrete and follow the manufacturer’s dosing instructions.
SNAP-IT is compatible with three main finishes:
Wait 30–45 minutes after pouring before finishing.
Leave your concrete to cure for 5 full days. Avoid heavy loads during this time.
Once cured:
Yes. SNAP-IT forms are designed to stay in place permanently. There’s no boxing to remove and no ongoing maintenance.
No. SNAP-IT is designed to be a permanent in-ground formwork system. Once installed and poured, the components are trimmed and stay in place as part of the edging.
