A raised patio, elevated from the ground and often encapsulated by a retaining wall, offers both aesthetic and functional benefits. It's an ideal solution for sloped terrains, providing a level area for relaxation and entertainment. In this guide, we'll delve into the steps and considerations for building a raised patio using retaining wall blocks and pavers.


Advantages of a Raised Patio

1)Minimal Maintenance: Unlike wooden decks, raised patios don't demand frequent upkeep.


2) Design Flexibility: They can take on any shape, multiple levels, and even include stairs.

3) Neat Appearance: Say goodbye to under-deck clutter.


4) Longevity: A raised patio adds enduring value to your landscape.


Constructing Your Raised Patio

The foundation of a successful raised patio lies in meticulous planning and execution. Start by sketching your desired design, marking out the area, and considering the location, size, and shape. Excavation follows, where you remove surface vegetation and dig a base trench. The depth and width of this trench are crucial, as they determine the stability of the entire structure.


Retaining wall construction is the next step. Here, the base is prepared, and the first course of retaining wall blocks is laid. It's essential to ensure these blocks are level and aligned. Backfilling behind the wall with wall rock and compactable rock or sand is vital for preventing settling over time. As you stack additional courses, always check for alignment and leveling.


Once the walls reach the desired height, it's time for patio flooring installation. Choices range from concrete, pavers, brick, to natural stones. A slight slope is recommended for water drainage. After laying the pavers, a plate compactor ensures they are level. The gaps between pavers can be filled with sand or a jointing compound.

Key Considerations for a Raised Patio

Drainage is paramount. Without proper drainage, water pressure can build up behind the retaining wall, leading to potential damage. The patio surface should also have a slope for water runoff. Base preparation cannot be emphasized enough. A well-prepared base guarantees the patio's longevity and stability. When selecting materials, choose those that resonate with your landscape's design and style. Allan Block's retaining wall blocks, for instance, offer a cohesive look. Lastly, always check local regulations. If your patio exceeds a certain height, you might be required to install a railing for safety.


CONCLUSION

In conclusion, while building a raised patio requires effort and attention to detail, the result is a beautiful, functional space that enhances your backyard's appeal. Whether for entertainment, relaxation, or property value enhancement, a raised patio is a commendable addition to any home.


FAQs

1. Does a raised patio need drainage?

Like any other Allan Block retaining wall, your raised patio needs to have proper drainage. A drain pipe is used to prevent water pressure from building up behind the retaining wall.

2. How deep should footings be for a raised patio?

The recommended depth you'll want to dig to is about 150mm or 6 inches from the finished patio level


3. Why is my raised patio sinking?

Your patio may be sinking because of the original construction. When the concrete was poured, those in charge of the project may have failed to make sure the base was stable.


4. What is the best sub-base for a patio?

MOT Type 1 is a crushed limestone, concrete or granite that contains no fines. It is the highest quality sub-base available and provides an excellent base for paving
