When planning a driveway in Auckland, the material beneath the surface matters more than most people realise. With regular rainfall, mixed soil types, and daily vehicle use, the long-term performance of a driveway depends heavily on the base layer. For most residential projects, Gap 20 aggregate is a proven and dependable option for Auckland conditions, provided it is installed correctly and matched to the site. What Gap 20 aggregate is and how it works under a driveway Gap 20 aggregate is a 20mm gap-graded crushed stone used for structural base layers. It compacts tightly while still allowing water to move through the base, which helps prevent moisture-related failure. This balance is why Gap 20 Aggregates Auckland is widely used beneath concrete, pavers, and other driveway finishes. Rather than sitting on soft ground, the driveway surface is supported by a stable, well-draining foundation. Why Auckland soil and climate affect driveway performance Auckland soils often contain clay, ...

Selecting the best base material depends on your project's load-bearing requirements, drainage needs, and surface type. Driveways need compacted aggregate like GAP-40, pedestrian paths work well with GAP-20, while lighter applications like artificial turf require finer materials such as GAP-7 for optimal stability and drainage. I learned this lesson the hard way fifteen years ago when I installed a beautiful paver patio in my backyard without properly understanding base materials. Within two years, sections had sunk, creating uneven surfaces and water pooling issues. That expensive mistake taught me that what's underneath matters just as much as what's visible on top. Whether you're planning a driveway, garden pathway, patio, or any outdoor hardscape project, the foundation literally makes or breaks your investment. A proper base prevents settling, manages water drainage, distributes weight evenly, and ensures your surface stays level for decades rather than months. Yet...

Yes, you can use Gap 20 aggregates around pools and outdoor entertaining spaces—but only if you understand how and where they work best. While Gap 20 is commonly used as a compactable base layer, it’s not always the most suitable option for top-layer finishes where barefoot traffic, aesthetics, and water management matter. The key lies in using Gap 20 properly—typically beneath more suitable surface materials—and ensuring it supports both function and comfort in your outdoor design. Why Even Consider Gap 20 Around Pools or Outdoor Areas? When people plan their outdoor spaces—especially around pools or patios—they’re usually thinking about aesthetics, safety, drainage, and low maintenance. So why does a construction-grade aggregate like Gap 20 come into the picture? Because it’s incredibly stable , cost-effective , and excellent for drainage when compacted correctly. Gap 20, which refers to a mix of stones and fines up to 20mm in size, creates a solid sub-base when compacted. It’s a...
