Sinhala (Sri Lanka)Tamil-Sri Lanka


National Building Research Organisation (NBRO) the premier research  & development institute established in 1984 has now grown in to a successful technical service provider and research & development institution where experts from multiple disciplines have teamed up and dedicated to create a disaster free built environment for the nation.


A Milestone for Quality Service at NBRO
  Building Materials Research & Testing Laboratory of National Building Research Organisation was granted ISO 17025 Accreditation for the “Performing Mechanical Testing on Concrete cubes & Steel bars as per ISO and SLS methods”. The first laboratory in Sri Lanka, granted accreditation for steel testing...

Newspaper article on “Landslide at Siripura in Aranayake Divisional Secretariat Division, Kegalla District”
The effects of climate change and climate variability give rise to frequent disasters globally, and the frequency of occurrence which has been observed as ever increasing. The situation in Sri Lanka is no exception, with landslides and flood incidents, becoming too frequent. Heavy and localized rains which fell in Sri Lanka during recent times caused an unprecedented disaster situation. Landslide means any type of movement of ground mass including land subsidence created due to natural causes or human activities. In the global context, landslides are triggered by earthquakes, volcanos, snow-melting and heavy rainfall. Almost all the time in Sri Lanka, landslides are triggered by rainfall. At times of heavy rainfall, water infiltrates through the top soil on the ground into the deep soil layers beneath, thus filling in empty pores in the soil. When the water in pores reaches close to saturation, it exerts a pressure internally, called as ‘pore water pressure’ and it causes the soil...

Remote Sensing Assessment over Niyadigala Landslide Area
NBRO recently flew a drone over the Balangoda landslide which is a large scale landslide occurred in Niyadagala, Pabahinna in Rathnapura District (476985.99 m E, 744040.48 m N) on 3rd May 2016 between 16.15 -17.00 Hrs. The landslide flowed through the "Pannil Oya" valley destroying the Niyadigala Arannasenasana Temple. The following figure (figure 1) shows the landslide location and surrounding features of the area. The stream flows to Samanala wewa (tank). Figure 1: Location and surrounding features Landslide: The landslide is approximate length of the landslide is about 1.5 km. The length of the main scarp is about 50 m & the height of the main scarp is about 29 m. Further, a 3D model was developed by using the aerial photographs, obtained from the drone. The figure 2 shows the debris flow path, surrounding settlements, and main features of the landslide. Figure 3 illustrate the landslide scarp which has occurred nearly 1250 m altitude. ...
