Just over a hundred years ago we had basements made by big old rocks. Fast forward some years and cinder blocks became the norm. Now the gold standard are prefabricated concrete walls with insulation and a water proof seal. One of my customers wanted photographs of their basement installation. All I can say is that their basement, to say the least is more impressive than my house. The foundations are made by Superior Walls. An impressive product by my uneducated view.
