Can you put landscape fabric under the pool?

Yes, you can put landscape fabric under a pool, and it’s often a good idea for several reasons:

Protection Against Sharp Objects	Landscape fabric can provide an extra layer of protection between the pool liner and the ground, helping to prevent punctures from sharp stones, sticks, or other debris.
Weed Prevention	It can help prevent weeds from growing up through the bottom of the pool. While weeds might not seem like a big issue under a pool, they can be surprisingly strong and might grow into the pool liner, causing damage.
Stability	Landscape fabric can help to stabilize the ground under the pool, especially if you put a layer of sand or other soft, level material on top of it. This can make the pool bottom more comfortable and ensure it stays level and stable.
Drainage	Good quality landscape fabric is designed to allow water to pass through while keeping soil and other materials out. This can help with drainage around the pool, preventing water from pooling underneath it, which could lead to issues with mold or mildew.

However, there are a few considerations to keep in mind:

Material Quality	Make sure to use a high-quality, durable landscape fabric for heavy-duty applications. Thin or poor-quality fabric might not provide the protection you need.
Installation	The fabric should be laid out smoothly and possibly secured to prevent it from bunching up or shifting, which could create uneven spots under the pool.
Pool Type:	This advice generally applies to above-ground pools. In-ground pools have different requirements and preparations for their foundations.
Additional Layers	Depending on the type of pool and the ground conditions, you might also need additional layers, like a cushioning layer of sand or foam padding, on top of the landscape fabric for extra protection and comfort.

Should I put landscape fabric under the deck?

Using landscape fabric under a deck can be beneficial for several reasons, but it also depends on your specific situation and the design of your deck. Here are some points to consider:

Benefits of Using Landscape Fabric Under a Deck

• Weed Control: Landscape fabric can effectively prevent weeds from growing up through the gaps in your decking. This is particularly useful in decks that are low to the ground where limited sunlight and airflow might not naturally inhibit weed growth.
• Moisture Management: Good quality landscape fabric allows water to pass through while keeping the soil underneath separate. This can help prevent excessive moisture buildup under the deck, leading to mold and mildew.
• Cleanliness and Maintenance: By preventing the growth of weeds and keeping the area under the deck cleaner and drier, landscape fabric can reduce the need for maintenance.
• Stability: In some cases, landscape fabric can help to stabilize the ground under the deck, although this is more of a secondary benefit.

Considerations and Tips

• Type of Fabric: Choose a high-quality, durable landscape fabric that is designed for long-term outdoor use and can withstand the conditions under a deck.
• Installation: Ensure that the fabric is laid smoothly and possibly secured to prevent it from shifting. Overlap the edges of the fabric to prevent weeds from finding their way through any gaps.
• Drainage: Consider the overall drainage of the area. While landscape fabric allows water to pass through, if the ground underneath does not drain well, you might need additional drainage solutions to prevent water from pooling.
• Combination with Other Materials: In some cases, laying gravel or small stones on top of the landscape fabric under a deck can improve drainage and stability, and also give a neat appearance.
• Deck Design: The effectiveness of landscape fabric also depends on the design of your deck. For decks that are high off the ground with good airflow and sunlight penetration, the need for landscape fabric might be less.
• Longevity: Be prepared that over time, the fabric may degrade, and soil or organic material may start to accumulate on top of it, potentially allowing weeds to grow. This means it may not be a completely maintenance-free solution.

Will water go through the landscaping fabric?

Composition and Design of Landscaping Fabric: Landscaping fabric is typically made from either woven or non-woven materials, such as polypropylene or polyester. Woven fabrics consist of interlaced threads, allowing for significant water permeability, while non-woven fabrics are made from bonded fibers, offering varying degrees of water resistance. The design and weight of the fabric influence how well it allows water to pass through; lighter fabrics tend to be more permeable.

Impact on Soil Moisture Levels and Plant Health: While landscaping fabric allows water to drain through, it can affect soil moisture retention. If the fabric is too dense or improperly installed, it may inhibit water from reaching the soil effectively, leading to dry conditions. This can negatively impact plant health, as roots may not receive adequate moisture. Therefore, selecting the right type of fabric for the specific plants and local conditions is crucial.

Recommendations for Use

To ensure optimal water flow when using landscaping fabric:

• Choose the Right Type: For areas with heavy rainfall or plants requiring more moisture, opt for a lighter, woven fabric.
• Installation Depth: Ensure the fabric is installed properly, with no overlapping edges that can trap water.
• Combination with Other Materials: In some cases, combining landscaping fabric with mulch can enhance moisture retention while still allowing for drainage.

Landscaping fabric can allow water to pass through, but its effectiveness depends on the type and installation. Proper selection and application are essential for maintaining soil moisture levels and supporting plant health. By considering these factors, you can maximize the benefits of landscaping fabric in your garden design.

Can I use a tarp instead of landscape fabric?

Using a tarp instead of landscape fabric is an option in some scenarios, but it’s important to understand the differences between these materials and their implications for your specific application. Tarps and landscape fabrics are designed for different purposes, and this affects how they perform in a garden or landscaping setting.

Differences Between Tarps and Landscape Fabric

Material	Tarps are usually made from materials like polyethylene or canvas and are designed to be waterproof. Landscape fabric, on the other hand, is typically made from a permeable material that allows water and air to pass through.
Water Permeability	A key difference is that landscape fabric is permeable, allowing water and air to reach the soil, which is essential for the health of plants and soil. Tarps, being waterproof, will prevent water from passing through, which can lead to water pooling and may cause problems with drainage and soil health.
Weed Control	Both tarps and landscape fabric can be effective for weed control, but they achieve this in different ways. Landscape fabric blocks sunlight while still allowing the soil to breathe and water to penetrate. A tarp, if used as a weed barrier, will also block sunlight but will create a more stifling environment for the soil.

Considerations for Using a Tarp

Temporary Solutions	Tarps can be useful for short-term applications, like covering an area to kill off grass or weeds before planting. However, for long-term solutions, their lack of permeability can be a disadvantage.
Water Drainage	If you use a tarp in an area where water drainage is important (like under a deck or in a garden), you might encounter issues with water pooling and poor soil conditions.
Durability	Tarps can be quite durable and resistant to tearing, which might be beneficial in certain situations where heavy-duty coverage is needed.
Heat Accumulation	Tarps can trap heat, which might be beneficial for warming up the soil in some gardening contexts, but this can also lead to overheating and harm plant roots or beneficial soil organisms.

While a tarp can be used in place of landscape fabric for certain applications, it’s important to consider the implications of its use, especially regarding water and airflow to the soil. For most landscaping and gardening purposes where soil health is a concern, landscape fabric is generally the better choice due to its permeability and ability to maintain healthier soil conditions.

In conclusion, investing in quality geotextile fabric under your pool deck is a wise decision to ensure its longevity and structural integrity. Its ability to control weed growth, manage water drainage, and provide a stable base contributes significantly to preserving your outdoor space. By making this thoughtful addition, you’re safeguarding your pool deck against common issues, allowing for prolonged enjoyment and minimal maintenance in the long run.
