Why Choose 7mm Gyra Rock for Paver Bedding?
Gyra Rock is a small angular aggregate that can be spread and leveled to prepare a setting surface beneath compatible paving stones and slabs. Its crushed texture distinguishes it from rounded gravel and fine washed sand.
When used in a suitable paving system, the bedding aggregate sits above the prepared structural base and helps establish a consistent setting elevation. The appropriate aggregate type, grading and bedding depth depend on the manufacturer's installation requirements.
Our 7mm Gyra Rock should not be confused with polymeric jointing sand or compacted road crush. Each material serves a different purpose in a hardscape installation.
