Lime allows you to build permeable wall systems, eliminating standing condensation. High Breathability: One of the outstanding benefits of using lime as an internal or external finish is its high porosity.Permeable: Lime absorbs moisture and allows it to evaporate.Availability: Lime raw materials are highly available in Egypt quarries are present across the nation and in various areas along the Nile valley – including Cairo (in Muqattam hill).Time-Tested: It is used as the main building material for centuries, most ancient monuments built in Egypt that still stand today were built with lime. With the rapid spread of quicker, more direct applications, the know-how of building with lime has been largely lost, and the facilities reduced due to supply and demand changes. The current training system works against anyone gaining this set of skills, as synthetic alternatives are dominating construction techniques. There is a real need for skilled labor in building with lime. Reutilization of lime can have large-scale positive effects on building in Egypt in economic and ecological terms if it is adequately explored and developed to match our modern-day construction requirements. Historical evidence, however, of use of lime in building for over 7,500 years of civilization history provides proof that the material has exceptional durability and resilience that makes it favorable over its new, faster-yielding synthetic counterparts. The promotion of modern gypsum-based plasters has led to the almost complete demise of lime plastering, as have the promotion of cement-based mortars and latex or emulsion paints for use of lime in these respective areas.
