Manufactures cement, has the monopoly over the Israeli cement market. Since the company sells more than 85% of all cement in Israel it is safe to assume that the separation wall, checkpoints and terminals, West Bank settlements and Israeli infrastructure in the West Bank were all built using cement purchased from the company.

Products of the company were seen in construction sites in West Bank settlements and in the construction of the light rail project in Jerusalem, which connects the settlement neighbourhoods of the city with the city centre.

According to reports, following calls from Amnesty International to clarify the company's involvement in the construction of the separation wall, the CEO of CRH, one of the company's owners, admitted in 2004 that "in all probability" Nesher cement is being used in the construction of the wall.
