I am looking at various options for a walkout basement wall system in climate zone 5. Besides a cast in place concrete I came across The Perfect Block and more recently Faswall (https://faswall.com/what-is-faswall/). Is the Faswall system any good? What does this look like from a water and air sealing perspective? Can it support a concrete floor system like LiteForm (https://liteform.com/litedeck-srs/)? Is it really that easy to install?
