When deciding to install an above-ground pool on the lawn, a pertinent question is what to put under the pool. The right base material can protect the grass while supporting the pool’s structure.
Proper ground preparation can make the above-ground pool experience much more enjoyable. This article explores the materials to use under a pool on grass.
Can a Pool Be Placed Directly on Grass?
Placing a pool directly on grass creates immediate problems for the lawn. This can potentially kill the grass by stopping access to all the essential resources. When a pool is placed on top of the grass, it blocks the sunlight and thereby prevents the process of photosynthesis.
There is also a possibility of dehydrating the grass by preventing water from reaching the grass. Therefore, keeping the pool in the same spot can eventually lead to the drying of the lawn.
Although it is possible to place a pool directly on grass, it is still better to remove the turf beforehand. The process involves using a sod cutter or shovel to clear the grass and its roots. Following this, make sure to clear the area of any rocks, sticks, or debris. The surface can also be treated with a weed killer to prevent any further growth.
Importance of a Base
A good base or foundation under the pool can help protect the pool liner from getting damaged. It also provides insulation, which contributes to maintaining the water temperature. A solid base can provide a smooth and level surface for the pool. Additionally, the base prevents weeds and vegetation from growing through the pool liner.
A base also becomes an absolute necessity to help in keeping the massive weight of the pool balanced. A level base keeps the pool's structure intact and prevents an uneven water line. Without proper leveling, there is also a remote possibility of the pool wall collapsing.
What to Put Under an Above-Ground Pool?
After the grass is removed and the ground is prepared, it is important to choose the right materials for the base. Here are a few options that can be best suitable as a level or foundation.
Sand
Sand is a traditional choice for creating a base under pools. It is a budget-friendly option, easy to level, and available in most places. It provides a cushioning that protects the pool liner while creating a suitable surface for swimmers. It also offers good drainage, thereby avoiding water from building up around the pool that may eventually cause erosion.
However, it also has a few downsides. One of the prominent cons is that sand can shift over time, which may gradually lead to uneven surfaces. To retain an even surface, it requires maintenance on a regular basis.
Foam Padding
This is one of the premium choices for pool bases, which offers excellent cushioning that can avoid punctures. This material can be a safe choice considering it reduces the risk of injury, further improving the swimmer’s experience.
In addition to enhanced comfort, it also provides better insulation when compared to sand. It helps retain heat in the pool, thereby extending the swimming season beyond summer.
On the other hand, this material’s prominent downsides are that it can be pricier than sand. But it offers long-term benefits that pool owners may find worth the investment.
Concrete Pads
This can be a solid and permanent choice for pool bases. They work especially well for installations on hard surfaces, while providing durability and stability. The concrete pads ensure that the pool remains level and secure for a longer period. Unlike sand, this base requires no regular upkeep and can help extend your pool's life.
However, it also has certain drawbacks. This method demands more effort, time, and expense to install, thereby making it a labor-intensive option. Additionally, most oval-shaped pools are not well-suited for concrete pads because of their structural design.
Pre-Cut Pool Pads
Their installation is rather convenient as they are made from durable and puncture-resistant materials. These pads are specifically designed to match various pool sizes. They ensure a precise fit while providing protection against damage.
Their initial investment can be quite expensive. However, they can be worthwhile since they require minimal maintenance and offer superior protection. They can be a popular choice among homeowners who are seeking a reliable and hassle-free option.
What to Use Under an Inflatable Pool on Grass?
Below are some commonly used ground covers to offer the best protection for the grass.
-
Ground Cloths: They are commonly included in inflatable pool packages and are easy to find. However, they usually tend to be of lower quality.
-
Tarps: They are waterproof material that comes in a variety of thicknesses, ranging from lightweight to heavy-duty. For the pool, a thicker and more durable tarp must be used. Ideally, they should be similar to those used to cover baseball infields during rain delays.
Make sure to fasten the tarp to the ground, and it should extend beyond the pool to cover the splash zone.
-
Mats: They can be placed on top of tarps to add more comfort. Make sure to use it with tarps, as they are an excellent combination for a base.
Conclusion
Setting up an above-ground pool on grass requires removing the grass and preparing a proper base. A well-prepared base ensures stability and longevity, further enhancing the swimming experience, especially in summer. They not only protect the pool liner but also help maintain the surface level.
