Question 1

What is drainage gravel used for in construction?

Accepted Answer

There are several benefits of using gravel for your drainage. Aside from keeping the water away from your home or building foundation, the use of gravel adds an aesthetic value to your driveway, pathway or yard. Gravel can also be used to direct any water towards ditches since gravel does not compact or degrade with time. Gravel is designed to remain firm and stable without maintenance.

It is always recommended to ask the advice of experts and professionals before you decide to buy drainage gravel. Drainage gravel comes in different shapes and sizes which can affect the stability and effectiveness of your project. For example, areas that regularly experience a heavy flow of water should use large drainage gravel.

The idea here is to prevent the drainage gravel from being compacted to keep the debris on the top layer. This will allow the water to drain and flow through the spaces between the gravel.

Question 2

What are the most common sizes of drainage gravel?

Accepted Answer

Drainage gravel sizes vary depending on your project. For example, french drains require gravel with sizes of 1-inch to 1-and-a-half inches. Generally, it is best to aim for a gravel size from half-an-inch to at least 1-inch for your drains. However, this may change depending on the size of the project. Larger stones are usually placed as the base and coarser sand as the top layer and filler. This sand does not clump or log, making it an ideal top layer.

Question 3

How expensive is drainage gravel?

Accepted Answer

Drainage gravel prices range from approximately $25 to $77. However, prices can still change depending on the size of the drain, location, gravel supplier and delivery fee.

Question 6

What is drainage gravel for?

Accepted Answer

Drainage gravel is used to manage water flow and improve drainage in various landscaping and construction projects. It is typically placed in areas where water tends to accumulate to prevent waterlogging and soil erosion. By creating a permeable layer, drainage gravel allows water to pass through easily, reducing the risk of water damage and maintaining soil stability. Common applications include use around foundations, in French drains, and under driveways and pathways.

Question 7

How does adding gravel help with drainage?

Accepted Answer

Adding gravel helps with drainage by creating a permeable layer that allows water to flow through it easily. This prevents water from pooling on the surface and helps to redirect it away from structures, reducing the risk of water damage and erosion. Gravel also aids in soil aeration, which can improve root growth for plants and prevent soil compaction. By facilitating better water movement, gravel enhances the overall health of landscaped areas and prevents flooding.

Question 8

What gravel is best for drainage?

Accepted Answer

The best gravel for drainage is typically clean, washed gravel that is free from fines and debris. Common choices include crushed stone, pea gravel, and river rock, with sizes ranging from 10mm to 40mm. Crushed stone is highly effective due to its angular shape, which creates spaces for water to flow through. Pea gravel and river rock are also popular because they are smooth and round, allowing for excellent drainage and ease of installation.

Question 9

Is 10mm or 20mm gravel better for drainage?

Accepted Answer

Both 10mm and 20mm gravel can be effective for drainage, but 20mm gravel is generally better for larger drainage projects. The larger size of 20mm gravel allows for greater water flow and less likelihood of clogging, making it ideal for applications such as French drains and around foundations. However, 10mm gravel can be suitable for smaller-scale drainage tasks, such as under pavers or in garden beds, where finer gravel is needed for stability and aesthetics.

| Gravel Size | Best Uses | Pros | Cons | | ----------- | --------------------------------- | --------------------------------- | --------------------------------- | | 10mm | Garden beds, under pavers | Good stability, aesthetic appeal | Slower drainage compared to 20mm | | 20mm | French drains, around foundations | Excellent drainage, less clogging | Less stable for fine applications |

Question 10

Can I dig a hole and fill it with gravel for drainage?

Accepted Answer

Yes, digging a hole and filling it with gravel can be an effective method for improving drainage. This technique, often referred to as a dry well or soakaway, helps to collect and disperse excess water. The gravel-filled hole allows water to percolate down into the ground rather than pooling on the surface. It is essential to ensure that the hole is deep enough and filled with clean, washed gravel to maximise its drainage capabilities.

Question 11

How thick should gravel be for drainage?

Accepted Answer

The thickness of gravel needed for effective drainage depends on the specific application. Generally, a layer of gravel should be at least 100mm to 200mm thick for most drainage purposes. For French drains and around foundations, a thicker layer, up to 300mm, may be required to handle larger volumes of water. It is crucial to compact the gravel properly and ensure it is evenly spread to create a stable and effective drainage system.
