Re: Retaining Wall
If the dirt behind the wall is 6-7 foot hi you had better get an engineered plan. So much to consider, type of soil, slope above the wall etc.There is no way that stacked block will hold back that much dirt if it decides to let loose. You would need tie backs and deadmen as well as geogrid placed stratigically thruout the wall to stabilize it. You also need a drainge system or the water can saturate the soil and not dry out and the weightg of wet soil is tremendously heavy. Most of the do it yourself blocks for walls are meant for 3-4 foot max hieght. I think the liability of doing what you suggest is foolish without an engineered plan. Doing the work yourself is fine but get a plan first
