Patios & Surfaces
Compare ground-level surfaces, base preparation and water management.
Concrete Patios: Slabs, Joints and FinishConcrete can create a durable, accessible surface, but base support, drainage, thickness, reinforcement, joints and curing determine performance.Paver and Brick PatiosSegmental paving is repairable and adaptable, but only when excavation, edge restraint, base, bedding and drainage are appropriate for the site.Natural-Stone PatiosNatural stone varies in thickness, strength, absorption, texture and weathering; the installation method must match the stone and climate.Outdoor Porcelain and TileExterior porcelain can provide a refined, low-absorption surface, but substrate movement, drainage, slip resistance and edge detailing are critical.Patio Base Preparation and CompactionExcavation depth, subgrade condition, aggregate selection, lift thickness and compaction determine whether a patio stays level.Grading, Drainage and RunoffAn outdoor surface must shed water without directing it into the house, a neighbour’s property, a retaining wall or an overloaded drain.Building Over an Existing Concrete SlabAn old slab can sometimes support a new finish, but cracks, movement, drainage, height and door clearances must be assessed first.
