Our old concrete patio had cracked in three places over the years. Trueform designed a flexible paver system that can actually move with the Ladner soil. Two winters in and nothing has cracked.

Ladner, Delta

Ladner, Tsawwassen, and North Delta each sit on completely different ground. We engineer hardscape that respects peat soils, dike rules, and coastal exposure.
Delta is not one place. It is three. Ladner is historic farming and fishing village on the north arm of the Fraser River delta. Tsawwassen is a coastal community with ocean views and sandy soils mixed with pockets of glacial till. North Delta (Sunshine Hills, Nordel, Scottsdale) sits higher on the slopes of the Burns Bog escarpment and has completely different construction conditions than the lower lying parts of the municipality. A contractor who treats Delta as one city will make expensive mistakes in at least one of these zones. We adapt our approach to where your property actually sits.
Ladner is where delta soil is at its most delta: organic peat, silty alluvium, and in some areas former marsh that was drained decades ago. The water table is shallow, the soil compresses under load, and dike authority rules govern anything close to the river. We use wider footprint base systems, flexible paver installations, and realistic expectations about long term settlement. Every Ladner project includes a conversation about what will shift slightly over the first year and how we will handle it under warranty. The payoff for building well in Ladner is one of the most characterful neighborhoods in Metro Vancouver.
Tsawwassen is a different world, though it is technically in the same municipality. The ground is sandy loam with pockets of glacial till, generally well drained and forgiving, and the climate is the sunniest in the Lower Mainland because of the rain shadow from the Olympic Mountains. Hardscape here performs well with standard base preparation but needs to account for salt air on coastal properties and for the views and sight lines that Tsawwassen homeowners value. We have built many elevated patios and multilevel backyards that take advantage of the ocean or Boundary Bay views.
North Delta, including Sunshine Hills, Nordel, Scottsdale, and Annieville, sits on the slopes rising out of the Fraser lowlands. The soil is better here than in Ladner (glacial till, silty loam) and drainage is easier, though mountain runoff is a factor in winter. Lots are typical suburban size with standard development permit area rules. North Delta is our most common Delta work zone because the construction conditions are predictable and the homeowner base is active. Delta as a whole enforces tree protection and setback bylaws that we scope into every project from day one.
Delta has the sunniest and driest climate in Metro Vancouver because of the rain shadow from the Olympic Mountains, with typically 1,000 to 1,200 mm of annual rainfall in Tsawwassen, slightly more in Ladner and North Delta. Coastal fog is common in the morning. Tsawwassen summers are dry enough that irrigation planning matters on every landscape project.
Ladner is organic peat and silty alluvium with a high water table, making it delta soil in the truest sense. Tsawwassen is sandy loam with pockets of glacial till and generally drains well. North Delta is glacial till and silty loam over the Burns Bog escarpment. Every Delta project starts with a soil assessment because conditions vary dramatically across the municipality.
The Corporation of Delta requires a building permit for retaining walls over 1.2 metres. Ladner has additional dike authority rules for anything built near the Fraser River. Tsawwassen has coastal setback considerations. Delta also has a tree protection bylaw that covers trees over 30 cm DBH. We verify all permits and protection zones before quoting.
In Ladner, accept that the soil will compress slightly and plan for it. In Tsawwassen, ask about salt air rated hardware on coastal properties. In North Delta, standard development permit area rules apply, so verify before designing. And in Tsawwassen specifically, plan for the dry summers with irrigation on any planting.
A Tsawwassen home with an English Bluff ocean view needed a patio that made the most of the sight lines without blocking them. We designed a 44 square metre Techo-Bloc Borealis paver patio with a 450mm low seat wall along the view edge, integrated low voltage LED lighting, and a pergola with retractable sun shades for the dry Tsawwassen summers. All metal hardware is marine grade stainless to handle the salt air.

Yes, but the design is very different from an upland project. Ladner peat and silty alluvium compress under load, so we use wider footprint bases, flexible paver installations, and realistic expectations about long term settlement. Every Ladner project includes a first year checkup under warranty to address any minor movement. Done right, a Ladner patio performs well for decades.
Yes, if your property is near the Fraser River or any of Delta's managed watercourses. Dike authority rules govern setbacks from dikes, restrict certain types of excavation, and may require additional permits. We verify dike authority implications for any project near water and coordinate with the authority when required.
Yes, significantly. Tsawwassen sits in the rain shadow of the Olympic Mountains and typically receives 1,000 to 1,200 mm of annual rainfall, roughly 60 to 70 percent of what Abbotsford or Maple Ridge gets. This means Tsawwassen landscape projects almost always need irrigation planning, and drought tolerant plant selection is standard in our Tsawwassen designs.
Yes. North Delta is one of our most common Delta work zones. The soil is better than Ladner (glacial till, silty loam), drainage is more predictable, and lot sizes are typical suburban. Standard development permit area rules apply in most neighborhoods, which we verify before designing.
Yes, for metal hardware, fasteners, and some finishes. We specify marine grade stainless steel fasteners on coastal Tsawwassen properties, recommend powder coat finishes for outdoor lighting and railings, and select paver colors that will not fade from coastal UV exposure. These are small decisions that matter a lot over a five to ten year horizon.
Delta paver patio costs range from $25 to $55 per square foot installed, depending on paver selection and base requirements. Ladner projects are typically at the higher end because of the base engineering required for peat soil. Tsawwassen and North Delta projects are in the standard range. A typical 400 square foot Delta patio costs $12,000 to $20,000.

The ocean view was the whole reason we bought the house. Trueform's low seat wall does not block the view and the pergola lets us use the patio on the hottest Tsawwassen days.
