Backfill behind embedded Versa Lok
The Versa Lok bulletins emphasize the importance of backfill behind the embedded/buried layer and recommend native back soil. Because the backfill is so important, wouldn't it be better to use CR8 for this backfill rather than soil? It would cost more but to me seems better. My wall is 4 foot at highest point and I bury a full 6" layer.
Any guidance would be greatly appreciated.
