Reconstruction of the Serpukhov–Leningrad Main Gas Pipeline, km 546.5–km 575.5

Preventing structural failure of an underground gas pipeline trench.

Trench construction in a casing made of Hydromat 3D/M, with the drainage side facing outward. This solution prevents mechanical damage to the gas pipeline due to the impermeability of the structure and prevents erosion of the trench structure by diverting water through the external drainage side of Hydromat.
 

• Easy to install without construction equipment
• Resistant to aggressive substances
• Operating temperature range from minus 60 °С to plus 65 °С.
