The Pyramid of Djoser has been controversially restored to save it after 4,600 years of damage from the harsh desert environment, earthquakes, looting and general deterioration. The builder, Imhotep, is credited with being the first recorded Architect in history.
The techniques used by the Welsh Engineers, Cintec International, challenged traditional architects’ views on the construction of Egyptian Pyramids and their restoration.
Cintec International used their patented anchoring system to reinforce the structure which was in a state of internal collapse in the main burial chamber. Stainless steel reinforcing bar enclosed in a mesh fabric sleeve were inserted into diamond drilled 100mm core holes to a depth of 30 metres. A special grout was then injected under low pressure into the sleeve.
