description
The 50 years old concrete roof of BAT Bangladesh was leaking, and leaking in spite of numerous efforts by its maintenance division. Their latest step of 'roofing felt' too failed to control the leaking. Astec Re-Ply System was installed by its authorized applicator in Bangladesh (Rafsha BD Ltd) in December 2012. The project management was very happy with the work because 'the problem roof' never leaked again till date. The presentation unfolds the waterproofing work in BAT Bangladesh. It was a tough job, but done easily.
