Vertical Walls with Concrete Facing Panels at Kempegowda International Airport

Compared to conventional structures, RS Wall system with precast concrete panels as facia and ParaWeb® as reinforcement was selected as the best solution due to its economy, flexibility, speed of construction, aesthetic finish, and long-term performance. 

Kempegowda International Airport Limited in Bengaluru is the third busiest airport with a high passenger traffic in India. The airport was initially designed with one passenger terminal of design capacity 11 Million Passengers Per Annum (MPPA) in 2008 and the first phase of expansion of airport was done in 2013 with a capacity of 25 MPPA. An expansion of existing main access road was required for easing out the traffic flow and vehicular under pass was made with widening on both sides without disturbing the traffic flow. 

Compared to conventional structures, Reinforced soil (RS) wall system with precast concrete panels as facia and ParaWeb® as reinforcement was selected as the best solution due to its economy, flexibility, speed of construction, aesthetic finish and long-term performance. Green space for plantation was also proposed over the RS Wall at few locations. As watering would be done for the growth of these plants, MacLine® layer below vegetative soil was proposed to avoid movement of water into the reinforced zone and act as a moisture barrier.
