Patio Installation — Richmond, BC
Richmond's flat geography is ideal for large patio layouts — there are no slopes to fight, and lot sizes in Steveston, Broadmoor, and Ironwood often provide generous backyard footprints. But flat terrain comes with a hidden cost: water has nowhere to go naturally. Richmond's high water table and delta silt soil mean that any patio without proper sub-base drainage will trap moisture underneath, leading to efflorescence staining on pavers, frost heave during cold snaps, and spongy spots where the base was never properly compacted. Getting the drainage right on a Richmond patio takes more care than people expect from flat ground.
Richmond's high water table pushes moisture up into the sub-base during wet months, requiring free-draining gravel layers and sometimes perimeter drain tile beneath the patio.
Delta silt-clay soil compacts poorly and retains water — patios installed directly on native soil settle unevenly within two years.
Flat terrain means water must be directed off the patio surface through engineered slope rather than relying on natural grade — every square foot needs deliberate grading.
Efflorescence (white mineral deposits) appears on pavers when subgrade moisture migrates upward through the base — proper aggregate selection and drainage prevent this.
Richmond patios need a drainage-first approach. We excavate to a full ten inches and lay geotextile fabric to separate the native silt from the granular base. Compaction happens in two-inch lifts with a plate compactor — no shortcuts. The finished surface slopes at two percent toward a permeable edge or catch basin because flat terrain means zero natural runoff. For larger Steveston and Broadmoor patios, we install perimeter drain tile beneath the base to intercept rising groundwater before it reaches the paver bedding layer. The surface looks flat — but the engineering underneath is anything but simple.
Patio installation in Richmond typically ranges from $5,500 to $28,000. Richmond's flat terrain keeps excavation costs moderate, but the additional drainage engineering and deeper sub-base requirements add to material costs. Larger Steveston and Broadmoor properties with expansive patio footprints push toward the upper range.

Those white deposits are efflorescence — mineral salts carried upward by moisture migrating through the sub-base. In Richmond, the high water table pushes moisture into inadequately drained bases year-round. We prevent this by using washed aggregate in the base, installing geotextile separation from the native silt, and adding perimeter drainage when the water table is particularly high. Existing efflorescence can be cleaned, but prevention is the real fix.
Yes, but never directly on the native soil. Richmond's delta silt does not compact properly and retains too much moisture for a stable patio base. We excavate the silt layer entirely and replace it with compacted road-mix gravel, then finish with a leveling layer of concrete sand. Geotextile fabric between the native soil and gravel prevents silt migration into the base over time.
Richmond backyards in Steveston and Broadmoor often support patios in the 250 to 500 square foot range — generous by Lower Mainland standards. Newer homes in West Cambie and Hamilton typically have smaller yards suited to 150 to 300 square foot patios. We design to maximize your specific lot, often integrating planters or raised edges to define zones within the patio footprint.
