Why choose Hardwood Sleeper H4?
Most landscaping failures come down to using the wrong treatment or sturctual grade timber in the wrong place. They are built specifically for soil contact, moisture and termite risk. Hardwood has a natural density and toughness that softwood alternatives can’t match, which matters when you’re building something that needs to hold soil (like garden beds) or carry structural load over years (fence posts). See our guide on treatment ratings.
