Concrete is the first material to use. Waterproof it and do it well and you don't need anything else.

Concrete is the only waterproofing material that cannot be damaged after it is complete.

Sometimes existing cellars can have a waterproof concrete floor then waterproof concrete walls inside the existing structure. Probably a minimum of 120mm thick.]]>
