Backyard pool paving walls are a big part of a great-looking and functional pool area. They provide the structure and support, as well as the style and glamour of your outdoor space.
In this guide, we cover everything you need to know about paving walls around pools, from choosing the right materials to keeping them looking great for years to come.
What is a Pool Retaining Wall?
A retaining wall is a structure designed to hold back soil, water, or other materials from a sloping or uneven terrain. In the context of a swimming pool, a retaining wall is an important component that helps to stabilise the soil around the pool area, preventing erosion and collapse.
Retaining walls can be made from various materials, including concrete, stone, brick, and wood, and are designed to provide a level surface for the pool.
Paving Materials for Pool Walls
When installing a paved retaining wall around your pool one of the first decisions you will make is choosing the right material. Here are some options to consider:
Natural Stone
- Bluestone: Durable and timeless bluestone is a popular choice for pool surrounds. Non-slip surface and salt water resistant makes it perfect for Australian pool owners. Natural stone can significantly enhance a traditional pool design by ensuring durability and low maintenance.
- Travertine is a luxurious natural stone with earthy tones and unique patterns. The blocks adds sophistication to your pool area and is cool underfoot, so it’s perfect for hot summer days.
- Limestone: Its soft, neutral colours and smooth texture create a peaceful and inviting pool area. It is highly durable and weather-resistant, so it will look great for years to come.
Concrete Pavers
Endless design options with colours, shapes and textures. Durable and low maintenance so cost effective for pool retaining walls.
Clay Brick Pavers

Material | Durability | Slip Resistance | Heat Resistance | Design Options | Cost |
Bluestone | High | High | Moderate | Limited | High |
Travertine | High | Moderate | High | Varied | High |
Limestone | High | Moderate | Moderate | Limited | Moderate |
Concrete Pavers | High | High | Low | Extensive | Low to Moderate |
Clay Brick Pavers | High | Moderate | Moderate | Varied | Moderate |
Things to Consider When Building Pool Retaining Walls
When choosing the right paving material for your pool retaining wall, you should consider:
- Durability and resistance to pool conditions: Your chosen material should be able to withstand water, chemicals and UV without deteriorating or losing its look.
- Slip resistance for safety: Safety is key around pools so opt for materials with a textured or non-slip surface to prevent accidents.
- Heat resistance and comfort underfoot: In the hot Australian summers you want a material that doesn’t absorb too much heat and is comfortable to walk on barefoot.
- Aesthetic appeal and design options: Choose a material that matches your home’s architecture and landscape design and has design options to create patterns and layouts that suit your style.
- Cost and long term value: Consider the initial cost and long term value of your chosen material, including durability, maintenance and potential resale value.
- Adherence to local building codes: Ensure that your chosen materials and designs comply with local building codes, which can influence the choice of materials, wall design, and the need for permits. Consulting a knowledgeable contractor can help in adhering to these regulations.
Drainage and Site Grading
Proper drainage and site grading are essential for a retaining wall to function effectively. The area around the wall should slope away from the pool to prevent water from accumulating and causing erosion.
A drainage system, including weep holes and perforated pipes, should be installed behind the wall to allow excess water to flow away. The drainage system must be regularly inspected and maintained to prevent clogging and ensure the wall’s stability.
Pool Paving Wall Installation Process
Installing a paved retaining wall around your pool involves:
- Excavation and base preparation: The area is excavated to the required depth and a solid compacted base of crushed rock is laid to provide a stable base.
- Laying the foundation: A concrete footing is poured to support the retaining wall and ensure its longevity.
- Installation of drainage systems: Proper drainage is key to prevent water from building up behind the wall which can cause damage and compromise the structure. Perforated pipes and gravel backfill is installed to facilitate drainage.
- Laying the pavers: The chosen paving material is laid on the prepared base to the desired pattern and level.
- Jointing sand and sealant: Once the pavers are laid jointing sand is swept into the gaps to lock them together and a sealant is applied to prevent stains and enhance the colour and appearance.
Maintenance and Care for Pool Paving Walls
To keep your pool paving walls looking great for years to come, we recommend:
- Regular cleaning and sealing: Sweep away debris and clean the pavers with a mild detergent solution as needed. Reapply sealant every few years to maintain protection and enhance the material’s natural look.
- Weeding: Use a weed killer or manually remove any weeds that grow between the pavers to keep it looking clean and tidy.
- Repairing damaged pavers: If a paver becomes cracked, chipped or loose replace it as soon as possible to prevent further damage and maintain the wall’s structure.
- Winterising in colder climates: In areas that freeze take steps to protect your pool paving walls in the winter months such as covering them with a tarp or applying a protective sealant.
Benefits of a Retaining Wall for Swimming Pool Areas
A retaining wall offers several benefits for a swimming pool, including:
- Stability and erosion prevention: A retaining wall helps to stabilise the soil around the pool area, preventing erosion and collapse.
- Aesthetic appeal: A retaining wall can be designed to match the style and architecture of the pool and surrounding structures, enhancing the visual appeal of the pool area.
- Increased safety: A retaining wall helps to prevent accidents and injuries by providing a stable and level surface around the pool or water features.
- Cost savings: A retaining wall can help to prevent costly repairs and maintenance by preventing erosion and damage to the pool and surrounding structures.
