What Sand Should I Use To Level Underneath My Pool

How Much Sand is in my Sand Filter Model {Ask the Pool Guy Q& A}

When undertaking the project of installing a swimming pool many homeowners dont realize how large the project truly is.

There are a ton of factors that will impact the project, however one of the most frequent questions we get about installing a swimming pool is which sand should be used underneath it.

Before your pool can actually be installed a level surface must be created that will allow for support of the pool shell. This surface is created with sand.

Whether a pool professional or yourself will be installing your swimming pool, youll need to be aware of the different types of sand that are available, and which is the right choice for creating a level base for your pool.

Weve decided to explore the different options that are available to you and which sand you should use for your pool.

The Importance Of Sand In Pool Installations

Although many homeowners take the time to determine the actual size, depth, installation and pricing requirements for a swimming pool, many fail to consider the fact that the pools shell will need to have a stable base beneath it. The last thing that you want is for the floor of your swimming pool to be uneven. This creates safety issues and inconsistencies in depth.

Being required to repair these problems in the future can result in the need to excavate, which can quickly become very expensive. Its important to understand that an extra 2-4 of depth should be excavated to account for a layer of quality sand. Because of the small particle size, sand will not feature any voids which could cause the material to settle and result in an uneven surface after the shell is set into place.

As such, sand is the most popular option for establishing a solid base for underground swimming pools.

Do You Have To Round Up Sand After Installing A Pool

Sand could have a high content of moisture and therefore weigh more. Always round up the next higher amount if they will not deliver 1/2 yards. There will generally be sand left over after the installation. NOTE VERY IMPORTANT: Always insist on masonry sand! Sand must not contain any rocks, stones, pebbles, twigs, trash, grass, etc.

    Calculating How Much Sand You Need

    Many builders and gardeners are faced with calculating or estimating the amount of sand they need to fill a given space with sand. Our sand calculator is of great utility in such cases, but you should keep in mind that the results will only be as good as the measurements entered. The calculation process is as follows:

  • Estimate the volume of sand needed, using geometrical formulas and plans or measurements.
  • The approximate density of sand is 1600 kg/m3 .
  • Multiply the volume by the density to get the weight
  • There is finer and more coarse sand, so the density, measured for dry sand in kg per cubic meter or pounds per cubic feet, of your particular shipment may vary. For this reason, and due to potential loses / waste, you should consider buying 5-6% more sand than estimated so you don’t run just short of what you need in the end.

    Ton Vs Tonne Tons Vs Tonnes

    When calculating the sand’s weight, make sure you do not confuse the tonne with the ton . The first one is used by all countries in the world and is defined to be equal to 1000 kg by the international body of standardization. The ton is currently only used in the United States and is equal to 2000 pounds . The difference between the two is not huge but can quickly add up to a significant number as the amount increases.

    Why Is My Sand Filter Blowing Sand In The Pool

    When Do I Need To Change My Filter Sand?

    Sand coming from the pool filter is the sign of a broken component in the filter. If you see it blowing out into the pool, something is broken. The most common problem is a cracked lateral, which is one of the perforated pipes at the bottom of the filter that catches water that has circulated through the sand.

    We Have A Chart For That

    It is commonly recommended by above ground pool manufacturers to have a 2″ sand base inside the pool, under the liner.

    This will help protect your liner, and provide a soft floor that provides comfort while walking in your pool. Always use masonry sand, which is a washed sand, free of rocks and debris. This is widely available for delivery from earthworks, and landscaping centers.

    For reference, we have provided a chart of sand requirements for common pool sizes below but for extra installation tips for above ground pools using a sand base see this link!

    The actual amount used in the pool may vary depending on the excavation and liner type used. See the base order of operations image below the sand chart.

    Calculate How Much Sand You Will Need Using The Sand Calculator

    You start by finding or building a straight 2×4 that is 1 foot longer than your pool diameter. In our case, we had a 15 ft pool so I attached two 2×4’s together to make one long 16 foot 2×4, as shown below. You will use this long 2×4 for leveling the sand as well along with any inexpensive carpenter’s level.. Click on photo to enlarge

    Then, place one end of the 2×4 on the high side of your pool site and raise up the other end until it is level. Measure the distance in inches that you must raise the end up. In the photo below, I had to raise the end 4 inches. This distance is what you enter in the calculator below. Note that if you have more than a 2″ drop, you should level out your site by removing soil from the high side – otherwise you may have problems with the pool sinking into the softer end more. Then measure again.


    Swimming Pool Site Sand Calculator

    Note that this calculator adds 3 feet to your diameter and calculates the sand to level your area. It then calculates an additional 2 inches of sand to place over the leveled area. If you have more than 2″ to level out, you should level out your area by removing soil from the high side first. Then remeasure.

    How To Calculate The Exact Size Of Sand Filter For A Swimming Pool

    How much sand do I need for my pool


    This is a very important topic when one comes to see the differences in the pool filters. Its not about the size of the filter its the flow rate which matters.

    Each brand of pool equipment have their own flow rates although the sizes could/would be similar compared to the diameter of the filter.

    The most common mistake pool specialist make during construction or refurbishment of swimming pools.

    Below are the calculation which will allow you to understand how one can select the perfect filter for a swimming pool:

    Firstly the pool volume is very important :

    · Example 1:

    ü Length Of The Pool: 8 Meters

    ü Width Of The Pool: 4 Meters

    ü Deep End: 2 Meters

    ü Shallow End: 1 Meter

    Taking the average depth of the swimming pool

    · Example 2:

    ü Deep End: 2 Meters

    ü Shallow End: 1 Meter

    ü Average Depth = Deep End + Shallow End/2

    ü Average Depth = 2+1/2=1.5 Meters

    Now we can find the total volume of the swimming pool in Cubic Meters

    · Example 3:

    ü Length Of The Pool: 8 Meters

    ü Width Of The Pool: 4 Meters

    ü Average Depth: 1.5 Meters

    ü Total Volume = Length * Width * Average Depth

    ü Total Volume = 8 * 4 * 1.5 = 48 Cubic Meters

    The next important point during filter selection is the turnover rate, the turnover rate is when all of the water in the pool has passed through the filters & cleaned. All turnover rate differ from country to country. We will be selecting the best one which is 4hours.

    ü Pool Filtration Turnover Rate = 4 Hours

    When Do You Need to Change the Sand in Your Sand Filter

    When putting the floor base for your above ground pool, you will have to use several pieces of 2 X 4 wood in order to make an outline on the ground. This will also serve as the mold that you will have to fill with sand. The form should be big enough to contain the pool above it.

    You will have to make a square mold or floor base for round pools and you will also have to make a rectangular floor base if you have an oval shaped above ground pool. If the ground is not level, you will have to raise a piece of the frame or one corner of the mold. Use a carpenters level to do this properly.

    As soon as all of the sides are leveled, you can then put the sand into the mold. The surface of the sand needs to be tampered and compressed in order to create a solid base for the pool. Use the table provided by the manufacturer so you will know how much sand you will need for a specific pool model.
