  Large scale constructions such as highways, bridges, high rise buildings, jetties etc. are designed to withstand heavy loads depending on the dead loads and imposed loads on the structure. For this purpose, loads from ...
• Low strain pile integrity testing for rock socketed bored piles in Sri Lanka 

  Kodithuwakku TH [Thesis-Full-text]

  Low strain pile integrity testing has been available over several decades. It is the widely used method of pile testing to detect serious defects in piles. The transient dynamic response (TDR) method of low strain pile ...
• Effectiveness of subsurface drainage and vegetation in enhancing the slope stability : a comprehensive case study on Badulusirigama landslide 

  Kankanamge LUM [Thesis-Full-text]

  Slope instability, triggered by excessive rainfall, is one of the common geo –hazards that geotechnical engineers are challenged with in tropical countries such as Sri Lanka. Typically, these slope failures are initiated ...
• Soil as a foundation material 

  Wijesinghe, S [Thesis-Full-text]

  Cement Stabilized Soil Blocks are now considerably popular in the construction industry as an alternative building material to burnt bricks and cement sand blocks. It provides a timely solution for the over exploitation ...
• Utilization of building debris as aggregates in stone column construction in Sri Lanka 

  Sanjeewa, KWD [Thesis-Full-text]

  Due to rapid development and population growth, construction industry has emerged with few recent problems. The major problem faced by the construction industry is the scarcity of construction material and disposal of ...
• Study on utilization of building debris in road construction in northern province of Sri Lanka 

  Shankar, P [Thesis-Full-text]

  Due to rapid development and population growth, construction industry has emerged with few new problems. The major problem faced by the industry is the scarcity of construction material and disposal of construction waste ...
• Possible use of bottom ash in embankment construction 

  Chrishanthi, JAC [Thesis-Full-text]

  Bottom ash is a solid residue byproduct produced by coal burning for electricity generation. In Sri lanka it has not been developed proper system to dispose of this bottom ash other than using small amount for concrete ...
