Our products in action
AM Surface protection systems have proven successful in all places where surfaces on and inside buildings are subjected to high or very high stresses, plus ageing.
The Cholfirst tunnel is located on the southern side of the Rhine between the Flurlingen exit and the Rhine bridge. It consists of a tube with three lanes. The existing coating of the tunnel walls was cleaned and roughened and then recoated with AM Surface Tunnel.
The existing concrete swimming pool, approx. 15 years old , was strongly attacked by the chlorides before the renovation and the surface was therefore very rough. For this reason, the coating was applied in two layers to cover the pores and cavities as completely as possible.
The Fäsenstaub tunnel is located on the northern side of the Rhine. It connects to the Rhine bridge at its south portal, the north portal merges into the Schönenberg Gallery. The two-lane tunnel is 1,460 metres long and has only a slight longitudinal inclination. The existing coating of the tunnel walls was cleaned and roughened and then recoated with AM Surface Tunnel.
In the underground car park all columns were coated in yellow and the walls in white, up to half their height.
In order to guarantee traffic and operational safety, the tunnels of the Thuringian motorways will be retrofitted step by step in order to bring the technical safety level up to the current state of the art (RABT 2006/2016).
The Alte Burg tunnel will be rehabilitated in two stages, the east tunnel in 2018 and the west tunnel in 2019.
The tunnel, which was originally kept in raw concrete, will be rehabilitated locally and coated with AM Surface Tunnel in a single operation.
The existing pedestrian underpass at Kiesen railway station is due to its location predestined for unwanted graffiti. The new coating is intended to simplify the cleaning of painted and sprayed areas and in particular to enable regular cleaning without permanent residue and damage.
The Serrières - Saint-Blaise motorway section has a length of 8 kilometres, is two-lane and has a daily traffic volume of around 40000 vehicles. Most of the line runs through tunnels, but there are also open and laterally closed sections.
Most of the rehabilitation work and in particular the renewal of the coating will be carried out during night-time closures (10 p.m. - 6 a.m.), so that the line will still be available for traffic during the day.
After the rehabilitation of defective zones in the concrete, the old coatings are mechanically roughened, cleaned with high-pressure water and then coated directly with AM Surface Tunnel in a single operation. In this way, the blocking times per coating stage can be kept to a minimum.
The Transolimpica Expressway connects the agglomerations of Recreiro dos Bandeirantes with Deodoro in Rio de Janeiro. The 25 km long motorway is equipped with two road tunnels. The link was built with a view to the 2016 Olympics to connect the Olympic Park with the Olympic Village.
AM Surface Tunnel complies with the safety guidelines of the Brazilian Association for Technical Standards (ABNT).
The old coating of the galleries (tunnels) of the A2 south ramp was overcoated with AM Surface Tunnel. A special process was developed for the pre-treatment of the old coating.
AM Surface Tunnel was selected in Küblis on the basis of an extensive pre-qualification procedure. In addition to the tunnel walls, SOS niches and escape routes were coated in orange and green with AM Surface Tunnel.
The coating of the Urnerloch tunnel as well as the coating of the galleries took place under climatically very demanding conditions at the onset of winter. The temperatures were around freezing point and partly dropped below it at night. Nevertheless, the material cured without any problems and is now in perfect condition after almost 5 years of operation.
The coating of the underpass was applied manually in two different shades of grey with an airless spraying device in order to enhance the colour of the building. The work was carried out in winter at low temperatures.
The Grota Funda and Andrade Gutierrez tunnels were built to connect the Recreio dos Bandeirantes and Vargem Grande districts with the Baixada de Guaratiba in the city of Rio de Janeiro. The project was carried out particularly in view of the 2014 FIFA World Cup.
The coating of the Rontal tunnel was carried out sometimes under very extreme weather conditions. The humidity was very high (about 100%) and the temperatures were low (2-10°C). The coating was applied manually with an airless spraying device. Despite the adverse weather conditions during application, the coating is still in perfect condition today and can be cleaned every year without any problems.
AM Surface Tunnel was applied in Saas for the first time with a mechanised machine. In addition to the tunnel walls, SOS niches and escape routes were coated in orange and green with AM Surface Tunnel. Despite the high salt load and low temperatures, the condition of the tunnel walls is still perfect today and the coated surfaces can be easily cleaned at any time.
The coating of the tunnel in Tuttlingen was carried out as part of a product evaluation. The coating was carried out manually using an airless spraying device.
