AGRU-Ultra Grip – for handling groundwater pressure

AGRU-Ultra Grip‘s patented conical stud design ensures the ultimate grip in concrete. By means of the newly developed AGRU-Ultra Grip concrete protection liner, groundwater pressures of up to 1.75 bar (at 20 °C) can now be permanently withstood. In large buildings, installation is even faster and cheaper, because by using the sheets of 5 m in width, which are also available from AGRU, you can save up to 60% of the welds that would normally be necessary. For an extra-long service life, AGRU-Ultra Grip also offers increased abrasion resistance.

Light signal layer so damage can be detected visually
Improved installation due to the white, reflective layer for optimal flatness on the formwork

AGRU-Ultra Grip – use in tunnels

In the case of large underground structures such as sewage tunnels and collectors, service life span is of utmost importance. AGRU-Ultra Grip is a widely proven solution here. Optimised installation techniques in conjunction with the large-format sheets of up to 5 m in width offered by AGRU enable corrosion-resistant and leakproof linings to be installed rapidly and for a reasonable cost. Channels of this type are built with an internal diameter of up to 6 m and have a single- or double-layer design.

AGRU-Ultra Grip - Combisegements

The Combisegments offered by Herrenknecht Formwork are ready-to-use segments equipped with a circumferential seal featuring AGRU-Ultra Grip. The tunnel is lined with singlelayer segment rings by the tunnel boring machine in a single pass and – thanks to this new technology – permanently sealed. This completely removes the need for two work steps, namely the retroactive installation of a concrete protection liner and the welding work in the tunnel. Time and cost savings are the result. The image on the right shows segment formwork with an inserted Combisegments lining.

Completely safe welds

AGRU-Ultra Grip sheets are joined using extrusion welding or hot-gas wire welding to create completely leakproof joints. Even cracks that occur in the concrete later on are bridged safely and permanently.

High media resistance

AGRU-Ultra Grip made of polypropylene has become indispensable in surface technology. Electrolytic pickling and high temperatures can damage unsealed concrete pools and basins. AGRU-Ultra Grip is resistant to media and prolongs the life of concrete pools and basins.
