Building a Concrete Pool on a Sloped Melbourne Block

Many Melbourne homes, from the Yarra Valley and Dandenong Ranges to the eastern suburbs, sit on sloping land. If that’s your property, a concrete pool on a sloped block is often the most flexible way to add a pool. Because concrete is engineered and formed on site, it can be designed to work with the fall of the land rather than against it.

Why Concrete Suits a Sloped Block

Unlike a pre-made shell that has a fixed shape and depth, a custom concrete pool is designed for your exact site. On a slope, that matters. A concrete pool can:

  • Be engineered as a structure: the shell is designed by a structural engineer to handle the weight of water and the pressure of the surrounding soil, even where part of the pool sits above natural ground level.
  • Follow the levels of your site: the depth, shape and position can be adjusted to balance cut and fill and reduce excavation.
  • Work with retaining: in some designs, a pool wall can be engineered to form part of the retaining for the site.
  • Create features from the slope: raised walls, vanishing edges, spillover spas and terraces all make use of the change in level.

How a Concrete Pool on a Sloped Block Is Built

Every site is different, but building a concrete pool on a sloped block usually follows these steps:

  1. Site survey and design: levels are measured across the block so the pool, paving and outdoor areas can be designed around the fall of the land.
  2. Soil testing and engineering: a soil (geotechnical) report and structural engineering determine the footings, steel reinforcement and any piers or retaining required. Melbourne soils range from reactive clay to rock, so this step is essential.
  3. Permits: in Victoria, a building permit from a registered building surveyor is required before construction. Taller retaining walls (generally over 1m) or walls near boundaries may also need engineering and approval.
  4. Excavation and retaining: the high side is cut into the slope and retained, while the low side may be built up. Access for machinery is planned carefully on steep sites.
  5. Steel and plumbing: reinforcing steel is fixed to the engineer’s design and plumbing is installed before the shell is formed.
  6. Concrete shell: the shell is sprayed (shotcrete) and allowed to cure, creating a strong, seamless structure.
  7. Drainage: agricultural drains and stormwater drainage divert water away from the pool and surrounding structures.
  8. Finishes and surrounds: coping, tiles or pebble interior, paving, landscaping and a compliant safety barrier complete the project.

Design Tips for Sloping Melbourne Blocks

A slope gives you design opportunities a flat block can’t offer. Ideas to consider include:

  • Vanishing edge: use the low side of the block to create an edge that frames the view. Explore our infinity swimming pools and infinity and vanishing edge pools in Victoria.
  • Raised spa spilling into the pool: a spa on the higher side can spill into the pool below. See our guide to adding a spa to your pool.
  • Feature walls: exposed pool walls on the low side can be finished in stone, tiles or render.
  • Terraced outdoor areas: separate levels for swimming, lounging and dining make the most of the slope.
  • Water features: waterfalls and sheer descents can use the change in level. Discover our luxury water features.
  • Pool fencing: plan barriers early, as changes in level and retaining walls affect compliance.

Sloped Block Concrete Pool FAQs

Is concrete the best pool type for a sloping block?

Concrete is generally the most flexible option for a slope because it is engineered and formed on site, so the shape, depth and structure can be designed to suit the fall of the land.

Does a concrete pool on a slope need engineering?

Yes. A structural engineer designs the shell, steel reinforcement, footings and any piers or retaining based on a soil report, so the pool can safely handle the load of water and soil.

Will I need retaining walls?

Most sloping sites need some retaining where soil is cut or filled. Taller retaining walls, or those near boundaries or buildings, generally require engineering and a building permit.

Is it more expensive to build a concrete pool on a slope?

Usually, yes. Extra excavation, retaining, engineering and drainage typically add to the cost. Careful positioning can help balance cut and fill and manage the budget.

Can part of the pool sit above ground?

Yes. Semi in-ground concrete pools are common on slopes. The exposed walls can be finished in stone, tiles or render to become a design feature.

How does drainage work around a pool on a slope?

Agricultural drains behind retaining walls and around the pool, along with stormwater drainage, help divert water away from the pool and nearby structures.
