What Should A Patio Be Laid On?

An important part of the decision-making process when installing a patio is the choice of a base to lay it on. The base, or sub-base, determines the strength, stability, and durability of the patio for years to come. Therefore, selecting the ideal base layer is crucial to ensure proper drainage, reduce shifting, and prolong the lifespan of your patio. This article explores the essential aspects to consider when deciding what material to lay your patio on, leading you to make an informed decision that suits your specific needs and preferences.

Essential Aspects

1. Drainage and Sloping

Proper drainage is paramount for any patio. A well-sloped base layer allows water to flow away from the patio, preventing pooling and potential damage. The slope should be away from the house or other structures to avoid water seeping into foundations. The recommended slope is 1 inch of fall for every 8 feet of patio length.

2. Strength and Stability

The base layer should provide a stable and firm foundation for the patio. It must be able to withstand the weight of the patio stones or slabs, as well as any furniture or foot traffic. The ideal base materials are those that can be well-compacted, such as crushed stone, gravel, or concrete.

3. Material Type

There are several materials to choose from for the base layer, including:

Crushed Stone: A popular and cost-effective choice. It is well-draining and stable, making it suitable for most patios.
Gravel: Similar to crushed stone, gravel is also well-draining but may need to be replenished periodically due to displacement.
Concrete: The most expensive option but provides excellent stability and durability. It can be used as a base for heavy patios or those subject to significant traffic.

4. Compaction

Compacting the base layer is crucial to ensure a solid and level foundation. Proper compaction prevents the base from settling or shifting over time. Use a plate compactor or a hand tamper to compact the material in layers, achieving the desired firmness.

5. Edging

Edging helps keep the base and patio materials in place, preventing them from spreading or shifting. Edging materials can include bricks, concrete blocks, or metal edging. Choose an edging that complements your patio design and provides adequate support.

Conclusion

Selecting the right base for your patio is essential for its longevity and functionality. By considering drainage, strength, material type, compaction, and edging, you can create a patio that meets your needs and enhances your outdoor living space. Remember, investing in a solid and well-laid base will save you time and money in the long run by preventing costly repairs or replacements.
