  Thanks Reza and Dinesh, since the issue of underpinning is on a high cost, decided to go in with use of bitumen on the sides of the covered foundation. i.e. expose the external foundation and use paint it with bitumen since i suspect that there is more of horizontal capillarity that become vertical hence the adoption of the method. The area has to an extent clay properties hence the trapping of side water that later vertically moves up the wall, will try it and watch what happens.
