It's commonly used to fill trenches, pack around ag‑pipes, and sit behind retaining walls to take pressure off the structure. Because it's free‑draining and doesn't break down, it helps stop waterlogging, reduces erosion, and keeps the area stable over time.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003eTo work out how much drainage gravel you require (volume) of cubic meters (m3), use the following equation: Wall Length x Drainage Hole Width (we recommend 300mm) x Wall Height\u003c\/p\u003e\n\u003cdetails\u003e\u003csummary\u003eInstallation\u003c\/summary\u003e\u003cp\u003eHYBUILT have partnered with only the most experienced installers across South East Queensland and Northern NSW, offering a complete design \u0026amp; construct solution through competitive pricing and innovation.
