Limestone Landscaping

• Contemporary courtyards – lay sawn limestone pavers in a stacked pattern for a seamless indoor-outdoor flow.
• Coastal gardens – combine limestone chips with hardy grasses for a dune-inspired look.
• Feature walls – use split-face blocks to create textural retaining walls that double as seating.
• Driveway borders – edge asphalt or concrete with pale limestone cobbles for contrast and drainage.
• Water features – limestone’s soluble nature produces gentle sculpting over time, perfect for cascades.

Our suppliers stock a breadth of sizes and finishes:

• Limestone chips for landscaping: 8–40 mm grades for mulch, paths and permeable paving.
• Boulders & rip-rap: stabilise banks or add natural accents.
• Hand-dressed blocks: ideal for garden edging or BBQ surrounds.
• Dimensional pavers and tiles: honed, sandblasted or brushed finishes.
• Crushed aggregate: sub-base material that compacts firmly.

Limestone quarries are located in Northland, Waikato and Canterbury, so freight costs will vary. Order 5–10 % extra to account for breakage and colour matching.

Limestone is alkaline and can gradually raise soil pH. Pair it with acid-loving natives like pohutukawa cautiously, or keep a buffer of organic mulch.

Avoid harsh acids that etch the surface. Instead, rinse with low-pressure water, scrub with a soft broom and use a pH-neutral cleaner such as diluted dishwashing liquid. For stubborn algae, apply a biodegradable oxygen bleach, leave for 10 minutes and rinse thoroughly.

Where limestone blocks form part of a structural element, ensure the design meets the durability requirements of NZ Building Code clause B2.

• Seal high-traffic pavers every 2–3 years.
• Sweep loose debris weekly to minimise tannin stains.
• Top up limestone chips each spring to maintain depth and weed suppression.
