How much does a concrete pool deck cost per square foot in Ottawa?

A concrete pool deck in Ottawa costs $8 to $50 per square foot installed, with basic broom-finished concrete at the low end ($8 to $14), stamped and coloured concrete in the middle ($14 to $25), and exposed aggregate or specialty finishes at the high end ($20 to $50) — making concrete the most versatile pool decking material available, with options for nearly every budget level.

The wide price range reflects the enormous variety of concrete finishing techniques available. All concrete pool decks start with the same basic process: forms are set, a gravel sub-base is compacted, reinforcing steel or mesh is placed, and ready-mix concrete is poured and screeded to the correct slope. What happens in the next 30 to 90 minutes — while the concrete is still workable — determines the final appearance and cost.

Broom-finished concrete is the most economical option at $8 to $14 per square foot. After the concrete is poured and floated smooth, a push broom is dragged across the surface to create a textured, slip-resistant finish. It is the same technique used for sidewalks and driveways across Ottawa. Broom-finish concrete is durable, safe (the texture provides grip for wet feet), and fast to install. It can be integrally coloured for an additional $1 to $3 per square foot, transforming a grey sidewalk appearance into a warm tan, sandstone, or terracotta tone. For a 500-square-foot pool deck, broom-finish concrete runs $4,000 to $7,000 installed.

Stamped concrete is the most popular pool deck choice in Ottawa, costing $14 to $25 per square foot. Stamped concrete mimics the appearance of natural stone, brick, slate, or wood plank using patterned stamps pressed into the wet concrete surface. A release agent (powder or liquid) is applied before stamping to prevent the stamps from sticking and to create colour variation that enhances the natural look. The concrete is typically integrally coloured and then the surface is sealed with a clear or tinted acrylic sealer that enhances the colour and provides a slight sheen. Popular stamp patterns among Ottawa pool owners include Ashlar slate, random stone, flagstone, and herringbone brick. For a 500-square-foot pool deck, stamped concrete runs $7,000 to $12,500 installed.

Exposed aggregate concrete costs $16 to $28 per square foot in Ottawa. The process involves pouring standard concrete with decorative aggregate (small stones, pebbles, or glass) mixed in, then washing or chemically retarding the surface layer to expose the aggregate before the concrete fully cures. The result is a naturally textured, slip-resistant surface with a distinctive pebbled appearance. Exposed aggregate is extremely durable, requires minimal maintenance, and ages gracefully — making it a favourite in Ottawa's established neighbourhoods where longevity is valued. The aggregate itself can be customized: local river stone for an earthy look, quartz pebbles for sparkle, or coloured glass for a modern aesthetic. For a 500-square-foot pool deck, exposed aggregate runs $8,000 to $14,000 installed.

Specialty concrete finishes — including micro-topping overlays, acid staining, and polished concrete — push costs to $25 to $50 per square foot. These finishes are more common for renovating existing concrete decks than for new installations, but they offer unique aesthetic possibilities. Acid staining creates mottled, translucent colour effects that resemble natural stone. Micro-topping overlays apply a thin (1 to 3 mm) cementitious coating over existing concrete, allowing a complete visual transformation without demolishing the old deck. These specialty options are less commonly offered by Ottawa concrete contractors, so expect limited local competition and higher prices.

Ottawa's freeze-thaw climate imposes specific requirements on pool deck concrete that affect cost. The concrete mix must include air entrainment — microscopic air bubbles mixed into the concrete that provide space for water to expand during freezing without cracking the slab. Air-entrained concrete is standard for all exterior flatwork in Ottawa and is included in the prices above. The sub-base preparation is equally critical: a minimum 100 to 150 mm of compacted granular material (Granular A or 19 mm clear stone) is required beneath the concrete to provide drainage and prevent frost heave. In areas with poor drainage or heavy Leda clay, Ottawa concrete contractors may recommend a thicker sub-base or the addition of drainage fabric, adding $1 to $3 per square foot to the preparation cost.

Slab thickness for a pool deck in Ottawa should be a minimum of 100 mm (4 inches), with many contractors recommending 125 mm (5 inches) for added durability. The extra thickness adds roughly $1.50 to $2.50 per square foot in concrete volume but significantly reduces the risk of cracking from frost heave and heavy use. Reinforcement options include welded wire mesh ($0.50 to $1.00 per square foot) or rebar on 300 mm centres ($1.50 to $3.00 per square foot). Rebar reinforcement is the better choice for Ottawa pool decks because it holds cracked concrete together if a crack does develop, preventing the slab from separating and becoming a trip hazard.

Control joints (saw cuts or tooled grooves) must be placed at regular intervals — no more than 2.5 to 3 metres apart in each direction — to control where the concrete cracks. All concrete cracks eventually; control joints ensure the cracks happen along predetermined lines rather than randomly across your decorative surface. Poorly planned control joints are a common shortcoming in Ottawa concrete work — insist on a joint layout plan before the pour.

Annual Maintenance Costs for Concrete Pool Decks in Ottawa

Sealed concrete (stamped, coloured, or specialty finishes) needs resealing every 2 to 3 years in Ottawa, at a cost of $1.50 to $3.00 per square foot for professional application or $0.30 to $0.60 per square foot for a DIY roller application using acrylic sealer from a local supplier. The sealer protects the colour from UV fading, prevents salt and chlorine damage, and maintains the slip-resistant texture. Broom-finished and exposed aggregate concrete do not require sealing but benefit from an optional sealer that makes the surface easier to clean and more resistant to staining.

Ottawa's winter de-icing salt is the enemy of all concrete, and pool decks are no exception. Never apply road salt (sodium chloride) or calcium chloride to a concrete pool deck. If you need traction on the deck during spring opening or fall closing, use sand or a non-chloride de-icer.
