What We Supply to Castle Hill
Castle Hill's established properties, sloping terrain and strong outdoor entertaining culture create a specific material demand that differs from newer suburbs.
Sandstone Pavers, Cladding and Steps
Sandstone defines Castle Hill's outdoor aesthetic. Established properties across the suburb have sandstone retaining walls built decades ago, sandstone paths, feature wall cladding and entertaining area paving and when homeowners renovate or extend, matching the existing stone is a real concern.
Our range covers every application: standard and diamond-edged pavers for paths and entertaining areas, rockfaced and smooth cladding panels for retaining and feature walls, step and riser sets for garden staircases, and pier caps and half slabs for fencing columns and entrance features.
All sandstone is Australian-sourced via our long-standing relationship with Gosford Quarries for consistent stone colour across multiple deliveries. Pair any sandstone purchase with our Premcoat surface sealers to protect the finish from staining and weathering.
For gravel driveways and feature paths, explore our aggregates and decorative stones range to complement sandstone work.
Premium Soils for Castle Hill's Clay-heavy Ground
Castle Hill's established residential areas sit on clay-dominant ground. Over time, this clay compacts, drains poorly and makes it hard for new plantings to establish. The fix amends the existing ground with composted blends and organic matter that break up the clay structure and improve drainage through the profile.
We stock premium composted garden soil blends, turf underlay mixes and organic matter specifically suited to this kind of renovation work.
If you're refreshing an established Castle Hill garden rather than starting from scratch, bring a description of the area and your current conditions; our team will tell you exactly what product to use and how much, before you spend anything.

Bulk Mulch and Bark
Castle Hill's established trees and garden beds benefit from regular mulching but it’s more than just about appearance. In the Hills District's clay-heavy soil, a proper 75mm mulch layer significantly reduces surface moisture loss through the warmer months and slows the cracking the clay undergoes when it dries.
Hardwood, pine bark, sugar cane and garden mix mulches are available in bulk cubic metre quantities or 50L bags.
Browse our mulches and barks range. Delivery direct to your Castle Hill property or pickup from our Galston Road yard is available.
Drainage and Stormwater Products
Castle Hill's terrain is not flat: older parts of the suburb have sloping blocks and terraced gardens where water runoff during heavy rain becomes a real problem if site drainage isn't properly designed.
Inadequately drained Castle Hill blocks develop erosion along garden edges, waterlogging in low spots and eventually structural movement in retaining walls.
We stock the full drainage product range: stormwater pipes, U-channel drains, end caps, couplings and fittings for residential and small commercial drainage work. We also carry a full range of sands, including paving sand and bedding sand for installation work alongside drainage systems and paved surfaces.
Structural Timber and Site Accessories
H2 treated pine for retaining walls is one of the most consistent Castle Hill requests we fill. The suburb's sloped blocks mean retaining structures are a standard part of any major garden project, and H2 treated pine is the practical backbone for both new builds and rebuilds.
We also stock weed mat fixings, surface sealers and paving cleaners so a Castle Hill project can run from ground prep to finished result through a single supplier. Channel drains and driveway drainage fittings are available year-round for hardstand applications.

Castle Hill is premium residential territory. The landscaping work done here is high-spec, high-spend and visible. Getting the materials right matters, and that starts with the supplier.
We've been supplying Castle Hill's landscaping trade and homeowners from our Galston Road yard since 1970. Over 55 years in this region means we know Castle Hill's soil conditions, terrain challenges and the material preferences of the suburb's residents.
Our team carries over 80 years of combined landscaping and building knowledge. When you ask us which sandstone product will match your existing wall, or what soil amendment your clay ground actually needs, you get a real answer.
Our relationship with Gosford Quarries means when you're working on a project that requires sandstone across multiple deliveries, we are capable of providing consistent stone colour. We're family-owned and multi-generational. If there's an issue with an order, you speak to the people who run the yard.
Unsure About How Much You Need?
Castle Hill renovations often span multiple product types: sandstone for the entertaining area, soil amendment for the garden beds, mulch across the whole yard, drainage products for a sloped section. Coordinating quantities across several materials in a single order is where mistakes happen.
Use the Martins quantity estimator before you order. Enter your dimensions and depth for each area, and it gives you a volume estimate in cubic metres for soils, mulches, sands and gravels.

What sandstone products are best for Castle Hill outdoor areas?
For retaining wall cladding, rockfaced sandstone panels are the standard choice in Castle Hill's established gardens, blending with the suburb's existing stone aesthetic. For entertaining areas and paths, standard or diamond-edged pavers work well, while step and riser sets handle sloped garden staircases. All our sandstone is sourced via Gosford Quarries, meaning consistent colour across multiple deliveries.
What soil works best in Castle Hill gardens?
Castle Hill sits on clay-dominant ground that compacts and drains poorly without amendment. Composted garden soil blends and organic matter break up the clay structure, improving drainage and root penetration. For established beds needing a top-up, we recommend premium topsoil blended with compost. Our team can advise on the right product for your specific site.
