GAP 15 (Fine Builder Mix)
Our GAP 15 (Fine Builder Mix) is a finely graded compaction aggregate made from a blend of small stones and fines. Designed for projects that require a clean, smooth, and easily compacted surface, this mix binds tightly when compacted, creating a stable and level base.
Because it contains both coarse particles and fines (General All Passing), GAP 15 is ideal for precise work where accuracy, finish quality, and stability are crucial.
This material is regularly used across Hamilton, the wider Waikato region, and throughout NZ for landscaping, small construction work, and surfaces that demand a strong, consistent foundation.
Ideal Applications
- Paver bases for patios, paths and courtyards
- Garden edging foundations
- Small domestic pathways & decorative areas
- Light foundations & formwork prep
- Leveling layers for finer construction work
- Underlay for small concrete pads
Its fine granularity ensures precise leveling and a compact finish that resists shifting.
