Collection: Patio & Walkway Base

A flagstone patio in Brockton or a paver walk in Plymouth lives or dies on what's under it. Skip the base prep and the first hard frost will heave every joint by spring. The Ottr build for a residential patio or walkway is 4–6" of compacted dense-pack base, then 1–1½" of bedding sand, then the surface stone or paver, with crushed fines or polymeric sand swept into the joints.

Base layer (4–6" compacted):

• Dense Pack ¾" to minus — the standard sub-base. Crushed sharp stone with fines that locks tight under a plate compactor.
• Crushed Concrete 1" to minus — recycled base, same compaction profile, friendlier price for larger patios.
• Gray Crushed Rock ¾" — alternative open-graded base for installs that need free drainage under the slab.

Bedding course (1–1½" deep, screeded flat):

• Concrete Sand — the pro choice for paver bedding. Sharp grains, locks under load, doesn't migrate.
• Coarse Sand — alternative bedding sand where you want faster drainage.
• Mason Sand — finer grain, used as bedding for natural stone walks where the surface needs to settle into the sand.

Joint & finish material:

• Blue Stone Dust — sweep into joints between flagstone and irregular natural stone walks.
• Blue Stone Rock ⅜", Brown Stone Rock ⅜", Gray Crushed Rock ⅜" — fine decorative top layer for stepping-stone paths or as drainage in pervious patios.
• Riverbed Rock ¼" and ⅜" — rounded river stone for softer-look pervious paths and decorative borders around the patio edge.

Sizing rule of thumb: 1 cubic yard of base covers ~80 sq ft at 4" compacted depth. A 12'×16' patio needs ~3 yards of base + 1 yard of bedding sand + the surface material. Add 10% for compaction.
