Bridge decks are exposed to high mechanical loads throughout their service life. In particular, climatic conditions play an important role in the durability of bridges. Waterproofing of bridges extends the durability of bridge structures and protects them from destruction.

Covering of bridges is exposed to heavy loads due to constant movement, which indicates the need to install a waterproofing system with the possibility of overlapping cracks, increasing protection.

Another important problem that can arise is the chemical aggression of various substances, such as salts and oils, which enter the asphalt and can cause the concrete to break. These factors suggest that the waterproofing system should have high chemical resistance.

Features of waterproofing of bridge structures

At the end of repair work or during the construction of a new bridge structure, before the final stage of laying asphalt or concrete pavement, waterproofing of the bridge deck is carried out.

In general, liquid rubber, roll waterproofing or bituminous mastics are used for waterproofing bridges.

Bridge waterproofing is a process that requires a special approach when choosing materials. Basic requirements for characteristics:

  • high heat resistance
  • elasticity
  • strength
  • seamless coating
  • high adhesion

The heat resistance of the waterproofing coating should be higher than the temperature of the asphalt coating. If the asphalt can burn the waterproofing layer, then such a defect will reduce the waterproof performance.

Roll waterproofing in the waterproofing of bridge structures:

BENEFITS

  • affordable price

DISADVANTAGES

  • elasticity
  • seams
  • adhesion

Liquid rubber forms an elastic seamless surface.

BENEFITS

  • elasticity
  • strength
  • seamlessness
  • quick hardening
  • heat resistance
  • repairability
  • adhesion

DISADVANTAGES

  • high price

What negative consequences should be expected if the waterproofing of bridge structures is performed incorrectly and water penetrates under the covering:

  • destruction of spans and the structure itself
  • corrosion of fittings

But in addition to financial losses for carrying out repair work, in this field, it is worth paying attention and being responsible for the safety and lives of people.
