Above Ground Pool In Irrigated Yard

(Chandler AZ)

Hello! So far this site has brought me the most comfort...

So aside from the fact that I measured wrong and started the above ground pool project in a spot that apparently infuriates my husband...... here is my problem:

We irrigate bi-weekly. I read in one of your other Q&As that you have built a birm around the pool and also a "birm platform". I was going for the birm platform. 12 tons of dirt and 13 hours later I realized I had measured wrong. Ok....get more. That was when I called my husband to "laugh" at how stupid I felt. That's when I was informed that it was the wrong place.

So tomorrow morning the crew is coming back out to fix this issue. It will be Sunday....Monday is irrigation day. They are bringing more dirt and also willing to move what they have already delivered.

We live in Arizona and it is steaming hot. Do you recommend the birm around or the birm platform? I had 6mil plastic covering the first platform to go under the tarp that comes with the pool. I wanted to be as safe as possible for weeds, erosion, gophers etc.

So now that I have to start over, I kind of like your birm around idea, but how do you prevent the birm from washing away? I also have a lot of 15 and 18 inch bricks I was going to use around the platform to hold down the plastic. My husband will not want to excavate away the grass, so how to I get rid of the vegetation? Still use the plastic and the tarp which will kill the grass until which time we decide to take the pool down?

Most importantly, where can I find pics of this? I am sure I a not the only person in the country who has done this, but I get nothing no matter what I search for on Google images. I am desperate! Help!!



Hi April. I'm sorry I can not help with photos. I have set pools on a raised area many times but none that I photographed.

Grass can grow through plastic, 2' or birm and then the liner if not properly dealt with. I would spray the ground with Doomsday before putting down the plastic and dirt. Just before the pool gets assembled I would treat the raised area again and use more plastic.

When installing a pool on a raised area you need to make sure you have about a three foot ledge all the way around the pool. This ledge could then get landscaped in a way that would prevent it from washing away. The biggest mistake people make is setting the pool to close to the edge of a built up area.

When using a raised area it is not necessary to use a second birm. Once the pool is installed it is good to cover the bottom rail with a little dirt and then your landscape plastic. Put rocks over the plastic and a border around the outside of the birm and it should all stay in place.

Uh oh.....

Well, birm is moved. What the 'landscape calculator' website told me would take 12 tons, took 24. The birm is 10 inches and has 2 layers of 6mil plastic, plus tarp that came with pool. After reading your response, I am very concerned about weeds. I didn't spray or treat for anything. We are keeping everything 'organic' . Also, there is about a foot and a half slope around the pool itself. Is this simply not enough? I am now really worried about the weeds and erosion. Other than the 2 layers of 6mil plastic and 2 rows of brick, can you think of any other preventatives for erosion? Probably nothing I can do about the grass at this point? Will weeds really go through 10 inches and 24tons of compacted dirt, 2 layers of 6mil visqueen and tarp???? Thanks for all the help I hope you get paid well for this. Maybe I'll take some pictures.



Hi April. The brick should be fine to hold the ledge in place and more plastic just before the pool installation should help with the weeds and grass.

Last step...I hope

Well pool is all up, but the instructions say that if the pool is not on concrete, I have to place supports pads under each support. They recommend 15x15x1.2inch pressure treated wood. I have called all over and no one has this size or can cut it. Alternatively, it says I can use steel pads or reinforced tiles. Again, google is not helping me figure out what these are or where I can get them. Any thoughts?



Hi April. Go to Home Depot and buy 2 x 8 x 16 inch masonry cap block, they will work just fine. Glad to hear the pool is up.

One more question!
by: April

Thanks for all the help. Do you think the cap blocks won't crack? I have several here from an old project and they seem to break really easy. I'm afraid that the weight of the pool will crack and break them....then split right through. I have the option of getting the pressure treated wood, but only 3/4 inch. Which would be the less of two evils? Thanks!



I would go with the blocks, or you could use both.
