  • Cons: Can be difficult to find, may not provide sufficient cushioning.

Installation Considerations: What Do You Put Under An Inflatable Pool On Grass

Preparing the grass area before installing the underlayment is crucial to ensure a smooth and stable surface for your inflatable pool. Here’s how to do it:

Leveling the Ground:Ensure the ground is level to prevent the pool from leaning or shifting. Use a spirit level to check for any uneven areas and fill in low spots with topsoil or sand.

Removing Debris

Clear the grass area of any debris, such as stones, twigs, or roots, that could puncture the underlayment or damage the pool liner. Use a rake or broom to remove loose debris and dig out any larger objects.

Placing and Securing the Underlayment

Once the ground is leveled and debris-free, roll out the underlayment over the grass. Overlap the edges by a few inches and secure them with stakes or weights to prevent shifting. Ensure the underlayment is taut and free of wrinkles or folds.

Drainage and Water Management

Effective drainage is crucial for inflatable pools on grass, as it prevents water from accumulating and damaging the pool or the lawn beneath. Different underlayment materials play a significant role in facilitating drainage and managing water runoff.

Materials like foam tiles or interlocking puzzle mats provide a solid base for the pool, but they may not offer optimal drainage. However, materials like geotextile fabric or gravel allow water to seep through, reducing the risk of waterlogging.

Managing Water Runoff

To prevent water from pooling around the inflatable pool, consider creating a slight slope away from the pool. This allows water to drain off naturally. Additionally, installing a French drain or perforated pipe around the perimeter of the pool can effectively channel excess water away from the area.

Impact on Grass Health

Placing an inflatable pool on grass can impact its health, potentially causing damage or inhibiting growth. The weight of the pool and water can compress the grass blades, blocking sunlight and airflow, leading to yellowing or thinning. Moreover, the chemicals used to treat pool water, such as chlorine, can be harmful to grass if not diluted properly.To

minimize damage and promote grass recovery, follow these tips:

Grass Preparation

Before setting up the pool, prepare the grass by mowing it to a shorter length to reduce stress. Aerating the soil can also help improve drainage and root growth.

Underlayment Protection

Use a suitable underlayment material, such as a pool pad or foam tiles, to distribute the weight of the pool and prevent direct contact with the grass. This creates a protective barrier that reduces compression and allows for better airflow.

Proper Pool Setup

Ensure the pool is level and evenly supported to prevent uneven pressure on the grass. Avoid overfilling the pool, as the additional weight can increase damage.

Water Management

Properly dilute pool chemicals according to the manufacturer’s instructions to minimize their impact on grass. Avoid draining pool water directly onto the grass, as the concentrated chemicals can cause burns.

Grass Care After Pool Removal

Once the pool is removed, the grass may need some time to recover. Water the area deeply and regularly to encourage root growth. Fertilizing the grass can also help restore its health and promote new growth.

Additional Tips and Considerations

To ensure your inflatable pool on grass lasts longer and provides optimal enjoyment, here are some additional tips and considerations:

Cleaning and Maintenance

Regular cleaning is essential to keep your inflatable pool hygienic and free from dirt and debris. Use a mild soap solution and a soft brush to gently scrub the pool’s surface. Avoid using harsh chemicals or abrasive cleaners, as they can damage the material.


When not in use, properly store your inflatable pool in a cool, dry place away from direct sunlight. Make sure it is completely dry before storing to prevent mold or mildew growth. Consider using a storage bag or container to protect it from dust and dirt.


Small punctures or tears can occur during use. Fortunately, most inflatable pools come with repair kits that allow you to easily patch up any leaks. Follow the manufacturer’s instructions carefully to ensure a proper seal.

Common Challenges and Solutions

Pool sinking into the ground:Place a layer of sand or gravel beneath the pool to create a more level and stable base.

Water leaking from seams:Check for any loose or damaged seams and apply sealant or repair tape as needed.

Pool becoming too hot:Set up your pool in a shaded area or consider using a pool cover to reflect sunlight and keep the water cooler.

Other Insights

Consider using a ground cloth or tarp under the inflatable pool to protect the grass from wear and tear.

Regularly check the water level and add water as needed to prevent damage to the pool’s liner.

If you have pets, keep them away from the pool to prevent punctures or tears.
