A real DaniCrete project in Greenacre — custom crack separation, dry sand and epoxy stitching, and a charcoal flecked spraycrete finish backed by a 3-year warranty.
This project in Greenacre involved a concrete slab with a particularly wide and long crack running through it. Instead of standard patching or costly demolition, we studied the slab behavior and applied a dedicated repair method.
Using a concrete cutter, two parallel cuts were made along the sides of the crack to isolate the damaged area from the slab. Perpendicular cuts were then made across the crack axis at measured intervals. The entire crack and cuts were filled with a mixture of dry sand and epoxy resin to stitch the two edges together, providing a solid bond backed by a 3-year warranty, finished with a full charcoal flecked spraycrete coating.
Step-by-Step
Each photo shows the actual progression on this Greenacre job — from initial cutting and epoxy-sand filling to the final flecked spraycrete.
01In this Greenacre project, the concrete slab had developed a very wide and long crack across the area. A close study of the slab's movement was conducted to design a lasting fix rather than a quick cosmetic cover.
02Using a concrete cutting saw, two straight parallel cuts were made along both sides of the longitudinal crack axis. This completely separated the cracked section from the rest of the slab to isolate movement.
03Across the crack line, perpendicular cuts were made at measured intervals along the length of the fracture to create stitching channels.
04The entire crack and cross-cut channels were filled and bonded with a specialized mixture of dry sand and epoxy resin, firmly locking both edges together and backed by a 3-year warranty.
05Once the epoxy-sand repair cured solidly, the entire concrete surface was resurfaced with a durable charcoal spraycrete base and decorative flecks for a clean, non-slip finish.
06A protective clear sealer was applied over the spraycrete, leaving a consistent, modern, and hard-wearing surface with zero trace of the previous cracks.

Rather than costly demolition and concrete replacement, proper crack isolation and high-strength epoxy-sand bonding provides a solid foundation for a long-lasting spraycrete surface.
