In preparation for the onset of winter, the College of Education for Pure Sciences has started a maintenance procedure for the roofs of the college by treating them with Isogam -Roll Roofing in order to preserve the buildings from damage due to the accumulation of rain during the winter season. The first stage  of the work included the maintenance of the building of the Department of biology, which consists of four sections, where the old layer was scraped and the surfaces were completely cleaned, and thus covered with Isogam -Roll Roofing
