This retaining wall is almost 2m high, it’s behind the house with a concrete slab between it and the house. Every now and then with water build up from heavy rain, it’ll seep out and cause light flooding just behind the house on the concrete slab. There’s no where for it go, so it either dries or I basically sweep it away to the side
Any advice to deal with this? Obviously cutting the concrete slab to make a drain isn’t ideal. Not sure how I can redirect it without tiling it or cutting concrete.
