Interlock Installation In Ottawa

Base preparation depends on the existing ground, drainage and intended use. Organic material and unsuitable ground are typically removed before a granular base is placed and compacted in layers. The required excavation, aggregate and base thickness depend on site conditions and loading. Bedding sand does not replace a properly prepared base.

Bedding sand forms a thin, consistent layer between the prepared base and the pavers. It is screeded to provide an even laying surface. It is not intended to fill deep hollows or correct an uneven base. The bedding material should be compatible with the paver system.

Edge restraint helps prevent pavers from moving sideways. Jointing sand fills the gaps and helps transfer loads between neighbouring pavers. Both are part of the paving system. The choice of restraint and jointing material depends on the pavers, the surrounding surfaces and the product requirements.

A driveway must account for vehicle weight, turning and repeated loading. A walkway is generally designed around foot traffic. Those uses can call for different paver thicknesses, laying patterns and base construction. The intended use and the paver manufacturer’s guidance should inform the specification.

Freezing water in the ground can lift paving, and thawing can leave an uneven surface. Settlement can also relate to soil conditions, drainage, compaction or loading. The cause needs assessment before deciding on repairs. Base preparation and water management help address these risks, but do not make paving immune to seasonal movement.

Use a plastic shovel, or a blade with a plastic or rubber edge, so it does not catch and chip a raised paver. Before using a de-icer, check the paver manufacturer’s guidance and choose a product it lists as safe for concrete pavers. In spring, sweep off leftover grit and check for settled pavers and washed-out joint sand.

Requirements depend on the location and scope of the work. Changes to a driveway entrance, work near a public right of way, steps and changes in grade can involve different rules or approvals. Check current City of Ottawa requirements before work begins. Grading also needs to account for runoff near the house and neighbouring properties.

Share the property location, photos from several angles, approximate dimensions and whether the area will carry vehicles or foot traffic. Note existing paving, steps, access constraints and any puddles or changes in level. A simple sketch and reference images can help explain the layout you have in mind.

Often, yes. Pavers can be lifted, the base corrected and the same pavers relaid.

It can be, when the pavers, pattern and base are specified for vehicles. Tell us the vehicles that use the driveway and whether the entrance at the street is changing.
