PRESS RELEASE


Euronext: LG, NYSE: LR		Paris, July 7, 2005

LAFARGE CONFIRMS ITS LONG-TERM COMMITMENT TO ACEH, INDONESIA

•

Investment up to 90 million US dollars to rebuild the plant

•

Launch of a program to rebuild 500 homes

Bernard Kasriel, Lafarge’s’ Chief Executive Officer, announced today to invest $ 90 million to rebuild the plant in Aceh, Northern Sumatra, Indonesia, providing the final reconstruction costs are in line with those detailed estimates. This plant was destroyed during the tsunami on December 26, 2004.

The new plant will be equipped with state-of-the-art technological standards and have a production capacity of approximately 1.6 million tonnes. It is expected to be operational by mid-2007. It will help economic recovery in the island’s northern regions which greatly suffered after the tsunami, as part of the Group’s aid plan for its employees, sub-contractors, and local communities.

“We have long been present in Indonesia, and today, beyond from the emergency situation, we would like to support affected populations and help contribute to economic development in this country, which is very needy in terms of reconstruction,” explained Bernard Kasriel, on site, on July 7, 2005.

Today, at the port of Lhoknga, Bernard Kasriel will launch a floating terminal used to unload cement imported by Lafarge from its Malaysian subsidiary to meet the high demand for cement in the region of Banda Aceh. This terminal will allow the delivery of up to 1,600 tons of cement daily until the plant’s activity starts back up.

The Lafarge Group has also launched a program to rebuild 500 homes, a school, and a mosque in Lamkruet, a nearby village about a mile away from the factory. Lamkruet was almost entirely destroyed by the tsunami. The first group of 275 houses should be completed by summer 2006, for a total of approximately $2 million. Lafarge will allocate its own funds to finance this operation, also using donations from Group employees throughout the world, and from other partners who offered their help for disaster recovery.

Each house will comply with government blueprints, complete with running water and electricity, and will include a bathroom, a bedroom, a living room, a kitchen, and a patio (see below). This reconstruction program is overseen by Lafarge in partnership with a local NGO, Dompet Dhuafa Republika, which handles relations with local communities, Habitat for Humanity, an international NGO specialized in providing housing for the underprivileged and Atlas Logistique, which has a high level of expertise in construction site management.

In parallel to this housing reconstruction program for tsunami victims, Lafarge has already renovated several mosques and schools in the province of Aceh, with the added service of mobile medical assistance across the area.
