Is caliche sustainable?

In terms of sustainability, caliche is an abundant sedimentary rock found around the world. Though it is not renewable, there's a lot of it. If you live in an area where caliche supplies are plentiful, choosing a local caliche supplier could be considered a "green" choice.

Does caliche hold up to rain?

Caliche is best used in drier climates. Not only is it created in arid and semiarid environments, it's more suitable as a road base material in drier climates.

Can caliche be obtained onsite?

In some cases, yes. If your jobsite has a large enough caliche deposit, it may be possible to extract and crush the caliche onsite. Depending on the ultimate use for the extracted caliche, you may need to have the soil tested. For example, if you plan on using onsite caliche for caliche block walls, the soil must be tested to ensure that the caliche is suitable for structural use and for meeting any applicable building codes.
