Landscape timbers are used for many outdoor projects, often as edging or stacked several rows high to construct sturdy landscape structures. Holding the timbers in place and securing them to each other requires sturdy hardware. There are several nail and spike options that work well with landscape timbers. Some are available in specific lengths, and others can be cut to your specifications. The hardware is economical and long-lasting and will hold your landscape timber project together for many years.
Steel pipe can serve as a strong anchor to hold large landscape timbers in place. Available at DIY centres and metal shops, you can cut them to length with a pipe cutter or have them cut at a metal shop. By drilling several holes through each timber and pounding the steel pipes through them, you can link rows together as you stack them to create a structure such as a short retaining wall.
Rebar (reinforcing bar) is commonly used to reinforce concrete during construction projects, but also works well to secure landscape timbers together. The timbers are held in place by pounding the rebar through predrilled holes and into the ground at an angle. In a single row they can then serve as edging to hold bricks or stones in place for walkways or patios. By securing several rows of timbers together with the rebar, and pounding it into the ground at least 30 cm (12 inches), you can create walls for a raised flower bed or vegetable garden.
Galvanised spike nails
Large galvanised spike nails work well in securing several rows of timber to each other to create a structure such as a children's sand pit. The galvanised coating resists corrosion, and it's not necessary to predrill holes for the spike nails. Pound the spikes into the wood with a hammer, using three or four in each timber to hold several rows together. Ensure that each spike is driven through one timber and deep into the next timber beneath for a secure fit.
Timber screws work well to secure rows of landscape timbers together, but unlike other hardware options, they're easy to remove if needed. Available in various lengths, these screws have a self-drilling point, so it's not necessary to drill holes in the timber beforehand. Because they're partially threaded, the screws wont back out of the wood like nails will. Install them with a basic 14-volt or larger power drill.
