Jack Weed Mat Pins are heavy duty galvanised steel pins that hold weed mat and landscape fabric flat against the ground. Each pin has a chiselled point that pierces fabric cleanly and drives into firm soil without a pilot hole, and they are supplied twenty to a pack. They are the fixing to use where plastic pegs pull out: compacted ground, gravel beds and windy open sites.
What it does
-
Steel, not plastic. Solid steel takes mallet blows into hard ground and keeps its shape instead of bending or shattering.
-
Galvanised against rust. The zinc finish is what gives them a long service life buried in wet soil under mulch.
-
Chiselled point. It slices the weave rather than tearing a ragged hole, so the fabric is not weakened around every fixing.
-
Doubles as an irrigation peg. The same pin holds irrigation tubing up to 19mm flat to the ground.
How to use it
Lay the weed mat out and let it relax in the sun before pinning, so it settles flat instead of bubbling later. Overlap adjoining sheets by a hand width, then pin through both layers at once along the seam. Space pins roughly every 50cm for the best holding strength, closing that up on exposed corners, edges and uneven ground.
Drive each pin by hand pressure where the soil is soft, or with a mallet where it is not, until the head sits flush against the fabric. Finish by spreading mulch or decorative stone over the top: it hides the heads, protects the fabric from sunlight and stops anyone catching a foot.
What it suits
Beds, paths and slopes. Anchoring weed mat under mulched garden beds and gravel paths, and holding landscape fabric and ground covers in place on slopes.
Beyond weed mat. Pegging irrigation poly line up to 19mm along a bed, and general residential landscaping work. Delivered Australia wide, with delivery from $29.95.
They are not for loose sand or very wet, soft soil, where any pin of this length works its way free. Twenty pins covers a small bed rather than a whole yard, so measure the run and order to suit.
