An EMS is an overall management system that includes organizational structure, planning activities, responsibilities, practices, procedures, processes and resources for developing, implementing, achieving, reviewing and maintaining the environmental policy of an organization. USAG Benelux and EMS is designed to ensure that all personnel, including contract personnel, whose work activities can cause a real or potential significant environmental impact, are aware of how their work supports the EMS and are competent to perform their roles, responsibilities, and authorities while supporting the Garrison’s mission. Contractors and their personnel are required to be aware of, and comply with, the Garrison EMS policy and legal and other requirements when performing work at an installation.

The Garrison EMS is explained during the contractor pre-performance meeting and/or in the EMS manual, which may be requested from the Environmental Division. The USAG Commander’s Environmental Policy may be viewed on line at:

- Breaking longitudinal elongation: 50%; breaking transversal elongation: 50%

- Dimensional stability: ≤ 0.1% (*)

(*) 15cm shrinking on transversal overlapping and executed according to prescriptions = 0mm.

Welding of membrane Rolls are aligned on the support with an overlapping of 10cm between each other, and folded back. Unroll the watertightness membrane, heating up its lower side to flux it; have the membrane adhere to the support. The overlapping must always be welded with a flame over their entire width of 10cm; edges are then pressed with a ±15kg roller. Transversal overlappings are 15cm. A small quantity of bitumen must flow off the overlapping joint. The bitumen cord may be beveled with the tip of the heated trowel.

Raised parts Raised parts totally shall be adhered by flame welding. Raised water tightness coverings shall be distinct from those applied horizontally, with which they connect at the basis of the 10cm min. overlappings welded with a flame. The angle of the raised part must always have two thicknesses. The edges shall be laid in max. width corresponding to the width of the rolls with an overlapping of 10cm.

Type of membrane: same as described in the “water tightness” item.

Remark Raised parts must at least be 150mm higher than the finished level of the roof, which is determined by the water tightness. Along the acroter, the raised part must be put under the wall cover.

Important remark

By decision of the Fire Chief of the U.S. Army, it is strictly forbidden to install heating devices (i.e. cauldrons) directly on the roof. The solution proposed by the contractor must be approved by the COR and the Fire Chief three (3) weeks before starting the work.
