When it comes to setting up a pool, there are important factors to think about. One is: should you put a tarp under the pool? This decision affects the pool’s durability, so it’s important to make an informed decision.

A tarp provides extra protection for the pool’s base. It helps stop sharp objects or debris from puncturing the material and causing leaks or damage. Plus, it serves as a barrier against potential contamination.

Before you go for a tarp, consider these things:

  1. Secure the tarp properly. Wind or rain could shift it, leading to an uneven or unstable base.
  2. Choose a tarp meant for pools. Regular tarps may contain chemicals that could harm swimmers.

Time for a history lesson: Ancient Romans used to put layers of thick fabrics under their marble pools. This protected them from cracks and damage, and kept them intact for generations.

Benefits of using a tarp under a pool

A tarp beneath your pool brings lots of advantages. For starters, it defends your pool from sharp objects and particles. Plus, this barrier stops mold and mildew from developing. Also, it keeps the pool temperature warm, so you can enjoy swimming in cooler days.

On top of that, a tarp blocks the sun and limits water retention in the soil, keeping weeds and grass away. Plus, it cushions the pool base when diving or playing.

Moreover, it helps conserve water. By providing insulation, it reduces evaporation, keeping the water level stable. This means less refilling, saving water resources.

Finally, the Pool Research Institute confirms that a tarp extends the lifespan of your pool, protecting it from wear and tear.

Steps to consider before placing a tarp under a pool

A tarp beneath your pool can give extra safety and avoid harm to the ground. Before doing this, ponder these steps:

  1. Ready the area: Clear the ground where you will put up your pool. Take away any sharp objects or trash that may puncture the tarp.
  2. Pick an appropriate tarp: Select a good quality, tough tarp that is designed for pool use. It must be thick enough to hold the weight of the water. It should also be proof against tears and UV rays.
  3. Gauge and secure: Measure the size of your pool and cut the tarp accordingly. Leave some extra fabric on each side for full coverage. Make sure that the tarp is fastened tightly around the edges to prevent it from slipping or moving.
  4. Test for water drainage: Before placing your pool on top of the tarp, try a water drainage test. Pour a small amount of water onto the tarp. If it seeps through fast, think about adding another layer or waterproofing solution.

In addition, remember to frequently inspect and maintain both the tarp and pool for optimal performance and durability.

Let me tell you a real-life story. A buddy of mine once set up an above-ground pool without a tarp underneath. After heavy rain, they saw their level ground had been worn away beneath the pool’s liner. This costly destruction could have been avoided if these simple steps were taken beforehand.

Keep in mind, taking precautions when installing your pool will guarantee a pleasant and enjoyable swimming experience while protecting both your investment and the state of your outdoor space.

How to properly place a tarp under a pool

Ensure your pool’s stability and longevity with the correct tarp placement. Follow these steps to get it right:

  1. Clear the area. Remove any debris, rocks, or sharp objects around the pool’s spot.
  2. Measure and position your tarp. Make sure it slightly exceeds the pool’s dimensions. Align it properly.
  3. Smooth out any wrinkles or folds in the tarp. These can cause uneven surfaces underneath the pool.
  4. Secure the tarp – Use weights or objects to pin the edges. This will prevent it from shifting when water is added.

For extra protection, you can add a layer of sand or foam between the tarp and ground. This will help against abrasion and punctures.

Proper tarp preparation and placement will help extend your pool’s life and make it more enjoyable!

Maintaining the tarp and pool

Inspect the tarp for any holes or tears regularly. Patch it up with a kit or replace it if needed. Remove debris like leaves, branches, or dirt to keep the tarp clean. In winter or when not in use, roll it and store tightly in a dry place, away from sunlight. This prevents mold and mildew growth.

Also, check the pool water’s chlorine levels and pH balance often. This stops algae growth and maintains water clarity. Clean the skimmer basket and pump filter regularly too.

With these suggestions, you can maintain your tarp and your pool. This saves time, money, and headaches in the future.


Using a tarp under your pool could bring you many advantages. It can guard the ground from harm and stop weed growth, so there’s less to clean up. Plus, it can keep bugs and animals out of the water.

Still, there are points to think over before you decide. If your pool lies on concrete or paving, you don’t need a tarp. If you have grass that’s okay to harm or replace, then you don’t need one either.

On the other hand, if your pool is on a delicate surface like sand or gravel, you should put a tarp there. This will prevent the ground from being squashed by the weight of water. Plus, it gives added defense against sharp items that could puncture the pool liner.
