COVER UP Sealing membranes

Landfills and contaminated sites must be provided with a qualified surface sealing system after the end of the deposition phase, in accordance with waste legislation. For this reason, the sealing of individual landfill sections or entire landfill surfaces is a key competence in today's landfill construction and in the remediation of contaminated sites.

Depending on the material composition of the deposits, the type and structure of the landfill or contaminated site, significant subsidence of the landfill body may still occur after backfilling has been completed. Particularly in the case of waste with a high organic content, larger settlements must be expected, which endanger the serviceability of a sealing. To avoid damage to the permanent surface sealing system, it is applied only after the main settlements have subsided. Since this process extends over a longer period of time, it is possible to first apply a temporary cover that is as impermeable to gas and water as possible.

COVER UP temporary waterproofing system was developed specifically for this application. The service life of COVER UP is dimensioned to outlast the decay phase of the main settlements until the final surface sealing system is applied.

Allgemein

COVER UP Sealing membranes is a special composite material whose inner layer is a tensile geofabric made of high-density polyethylene (PEHD). This carrier fabric is fully covered on both sides with a triple coating of Low Density Polyethylene (PELD) in a special working process. This special combination of materials in sandwich construction allows COVER UP to be impermeable to liquids and gases despite its low thickness and low weight per unit area, while maintaining high mechanical resistance.


Project specific fabrication

The COVER UP Sealing membranes are prefabricated in the factory to form large tarpaulins. Furthermore, COVER UP geomembranes are also available in rolls. Depending on the project, the width can range from 20 m to a maximum of 60 m and the length from 50 m up to a maximum of 200 m. For this purpose, individual sheets are welded together in a fully automated process to form one large tarpaulin. The production line is capable of making up to 20,000 m2 COVER UP tarpaulins per hour. After welding, each tarpaulin is specially prepared for shipping. The COVER UP tarpaulin is carefully folded, equipped with lifting straps and provided with an easy-to-understand "unfolding sketch".
The prefabricated tarpaulins allows to reduce the connections to be made on the construction site to a minimum. This means that even large areas can be covered and sealed extremely quickly. Depending on the geometry of the structure and project-specific requirements, the prefabricated tarpaulins can also be produced in special formats if required. The effort required for installation on site can thus be reduced even further. The use of specially developed planning software made this additional service possible. This calculates the best possible result for the fabrication on the basis of the specified geometry.
On the construction site, the COVER UP Sealing membranes can simply be welded with hot air or sewn by machine. If required, the COVER UP tarpaulins can be equipped ex works with special accessories such as reinforced edges, handles, steel eyelets, buckles or Velcro fasteners.

COVER UP Sealing membranes are CE certified and undergo extensive quality management at the factory. Thanks to many years of experience gained from projects with a wide variety of requirements, the geomembrane has undergone continuous further development. Today's COVER UP provides the user with the right solution for temporary waterproofing.
