Methodology & Quality Control

Our 4-Phase Installation Standard

Every project follows our strict Australian engineering workflow to eliminate drummy hollow sounds, lippage, and water ingress before tiles are placed.

01
Phase 01

Stone Grading & Dry-Lay

Each individual flagstone is categorized by thickness, face texture, and hue, then tessellated dry on site to guarantee balanced geometric distribution.

Phase 02

Hand-Dressed Edging

Artisans trim and shape stone perimeters using diamond cut-off saws and stone carver chisels to establish consistent 10-15mm mortar gaps.

Phase 03

Polymer Slurry & Wet Bedding

The reinforced concrete base is wet-primed with synthetic latex bonding slurry before stones are solidly bedded into thick M4 polymer mortar.

Phase 04

Flush Pointing & Siloxane Seal

Joints are filled with dense polymer mortar, struck flush, sponge-cleaned, and treated with deep penetrating breathable siloxane barrier.

Technical Clarifications

Frequently Asked Questions

Detailed engineering answers regarding Australian Standards, adhesive classes, and substrate prep.

Q1: Will crazy paving crack or lift over time?

When installed over a properly engineered reinforced concrete slab with flexible expansion joints and synthetic bonding slurry, our crazy paving will never crack or delaminate.

Q2: Which natural stones work best for pool surrounds?

Sydney Sandstone and dense Australian Bluestone are ideal because they remain cool under Australian summer sun and offer natural P4/P5 slip resistance.

Q3: How do you clean and maintain crazy paving?

Our siloxane penetrating sealers protect against oil, red wine, and organic tannins. Regular gentle pressure washing or neutral pH stone wash is all that is required.
