We planted 3 large Schipkaensis next to a new foundation facing south and they are not doing well. The leaves have turned brown and are dropping. We have already replaced one within a 6 month period. We planted high and watered very well. Does a new cement foundation have an affect on survival?

Quite possibly. Cement and mortar are very alkaline, and will leach for years, quite copiously while new.

Schipkaensi [like rhododendrons and azaleas] prefer acidic soil. You can try mixing agricultural sulphur into the soil as a neutralizer, but I honestly wouldn't want to guess how effective it would be in lowering the alkalinity.
