The National Building Research Institute states that the Lower Kadugannawa area is under constant surveillance of the associated road and railway line.
The technical director of the ministry RMS Bandara stated that steps will be taken to install a landslide warning system at the site.
Due to the adverse weather conditions prevailing in the island recently, there was a risk of landslides in this area and due to that the road was closed for a week.
Meanwhile, the Building Research Organization (BRO) has launched an investigation into the incident and is monitoring the situation from time to time.
