This anisotropicplus video shows how we used a French Drain to block excessive rainwater from flooding the portion of our house built on a slab. Although a drainage system had been installed earlier it was overwhelmed by the January, 2023 atmospheric river. Although the house survived we knew it had come close to being flooded. We decided to use a French Drain design combined with an in ground outdoor sump pump to protect the house. It works great! French drain https://en.wikipedia.org/wiki/French_drain
