The Dhwaja Sthambham (the sacred post in front of the temple) of Lord Venkateswara Swamy Temple on the hill, opposite to BHPV Township in Visakhapatnam, has deteriorated due to ingress of moisture that facilitated development of pest. Hence the Punah-Pratishta of this sacred pillar was conducted on 3rd-5th February 2014. This time, the temple authorities desired to make it resistive to pest attach and approached the scientists. the pit, holding the Pillar, is filled with Nano Concrete (NAC) for its characteristic ability in rendering absolute impermeability (27-100 Coulombs) associated with high strength (60 MPa at 28-day and 100-120 MPa at 1-year).
