G6 Filling (Sub-Base) – General Compaction Material

Reliable Compaction at a Lower Cost.

G6 Filling is the industry workhorse for general earthworks. It is an engineered natural gravel that is slightly less refined than G5 but still offers excellent compaction properties. It is the perfect middle-ground between cheap “Normal Filling” and premium “G5.”

Why Choose G6 Filling?

Budget Friendly: It is cheaper than G5, saving you money on large volume projects without sacrificing too much structural integrity.
Structural Strength: Unlike “Normal Filling” (which can sink), G6 is designed to be compacted. It forms a stable, non-sinking platform.
Versatile: Suitable for the vast majority of residential construction tasks.

Application Guide:

Foundation Fill: The most common material used to fill the space under concrete floor slabs in houses.
Paving Sub-Base: Ideal for walkways, patios, and residential driveways (where heavy trucks won’t be driving).
Backfilling: Excellent for stabilizing ground behind retaining walls.

Delivery: We deliver bulk loads of G6 Filling to Pretoria East, supplying builders and DIY homeowners

Common Questions:

What is the difference between G5 and G6? G5 is higher quality with stricter grading standards (more stone, less clay). It is used for roads and heavy-duty driveways. G6 is slightly lower quality (might vary slightly more). It is perfect for house foundations and standard driveways.
Can I use G6 for my driveway? For a standard residential driveway (cars only), Yes, G6 is usually sufficient. If you plan to drive heavy delivery trucks or construction vehicles on it, we recommend spending the extra money on G5.
How do I compact it? Spread it in layers no thicker than 150mm. Water it well, then use a “Whacker” (plate compactor) or a pedestrian roller until it creates a hard, solid surface.
