Engineered concrete mixes from C15 to C40 — batched to specification and delivered to your site.
Concrete strength classes describe the compressive strength of the hardened concrete. Choosing the correct class for each building element is essential for safety and durability — our team is happy to advise.
| Class | Typical Applications | Notes |
|---|---|---|
| C15 | Blinding, levelling layers, non-structural fill | Simple, economical mix for preparation works |
| C20 | Footpaths, floor screeds, light-duty slabs | Reliable all-rounder for residential works |
| C25 | Foundations, ground floor slabs, residential structures | The standard choice for most home construction |
| C30 | Suspended slabs, beams, columns, driveways | Structural-grade concrete for loaded elements |
| C35 | Commercial structures, heavy-duty floors | Higher strength for demanding structural work |
| C40 | Roads, industrial floors, engineered structures | High-performance mix for specified projects |
Special mixes (e.g. waterproof concrete, rapid-setting or pump mixes) available on request.
Site-mixed concrete depends on whoever holds the shovel that day. Ready-mix from GLD Concrete is produced against a defined mix design with weighed ingredients, controlled water content and documented batching.
