If you have ground water concerns, you'll want to use a mix of either vermiculite and Portland cement or you can use what the pros do and opt for Pre-Mix.
There are 4 choices to use for the pool base.
- Sand & Portland Cement
- Vermiculite & Portland Cement
- Pre-Mix; also call Pool Krete® or Pool Crete
We cover the details of each and when it is best to use them here in this blog. <-- includes a chart for how much to use!
