My concern is that its an outer wall, will wall panel withstand the blazing sun in summer and rain in rainy season?
As far as the source goes, there are underground water tanks on three sides and people are noncooperative. So whatever needs to be done is by me only
Is it possible that I rebuild a part of my side wall where seepage is most and then place a polythene sheet so that seepage can be stopped for at-least some years?
