How Much Base Should Be Under an Interlock Patio?

Homeowners across Brantford and Ancaster often ask this question before they start calling contractors: How Much Base Should Be Under an Interlock Patio? The useful answer comes from understanding the property, the materials, the amount of preparation required, and how the finished space needs to perform for years after installation.

Base depth is site-specific

There is no responsible universal base depth for every yard. Soil, drainage, load, paver type, frost exposure, and existing conditions all matter. The critical principle is removal of unsuitable material, proper granular selection, placement in compacted lifts, and stable edge restraint.

The base matters more than the brochure photo

Paver colour and pattern are important, but the unseen work determines whether the surface stays flat. Proper excavation, drainage, granular base, compaction, edge restraints, and accurate elevations should be clearly described in the quote.

Plan water before laying stone

Patios must drain away from the home and should not create runoff problems for neighbouring properties. Downspouts, low points, steps, pool decks, retaining walls, and lawn grades should all be coordinated before final elevations are set.

Maintenance expectations

Interlock is not maintenance-free. Occasional cleaning, joint maintenance, vegetation control, and localized repairs may be needed. The benefit is that individual areas can often be serviced without replacing the entire patio.

Questions to ask before moving forward

• How will the area be excavated and compacted?
• How will water drain from the finished surface?
• What paver, border and jointing materials are included?
• How will steps, edges and transitions be finished?
