Bridge waterproofing with polyurea

With polyurea, we create a tight, seamless and root-repellent bridge waterproofing system on your behalf. And in many cases, this is necessary. If a pothole opens up on a road, in the very worst case the axle breaks. As a rule, you either avoid a pothole or simply drive over it thanks to the good shock absorbers. This is different for a bridge. Corrosion and wear often have fatal effects here due to the height. A fall with a vehicle from a bridge usually ends in the hospital – or with even worse consequences.

Therefore, the public sector, responsible for bridge construction and maintenance, is also increasingly adopting the view that bridge sealing with polyurea is the best solution. Thus, experts create a surface through which no water, de-icing salt, oil, gasoline, diesel, as well as other chemicals can seep.

Bridge sealing with polyurea – excellent load distribution

Load management is important for bridge construction. A bridge must absorb, carry and support not only the live load but also the dead load. Therefore, bridge structural engineers must accurately calculate the distribution of weight – even for structural elements added later. The less additional load, the better. Therefore, the bridge waterproofing with polyurea is also a good idea. It is enough to apply a very thin and therefore particularly light layer. The additional weight should usually fall within the tolerance of the bridge.

Even though polyurea quickly becomes particularly hard, it is still a highly flexible material. And that’s an advantage – especially for bridge rehabilitation and bridge repair. Bridges are not rigid objects. The ground works and they not infrequently get a real broadside from the wind. So a bridge moves and sways. In addition, a bridge expands at high temperatures. The bridge coating with polyurea goes through all these movements.

These advantages it also has to perform bridge waterproofing with polyurea:

• High impact resistance
• Bridges cracks in the substructure
• Prevents deposits from plants
• Extremely weather resistant
