Advancements in rolling techniques have enabled us to build up beams with Hot Rolled Flanges with interlocks to thread MHZ Sheet Piles. The resulting Beam acts as a King Pile providing the required stability and load bearing of the wall. The intermediary MHZ sheet piles help to transfer the load and cut off any soil erosion behind the wall.

For high strength retaining walls that require section modulus larger than 5200 cm3/m, a combination wall will be required. A combi-wall is a combination of a king pile together with sheet piles or interlocking elements to provide a continuous wall to retain the soil behind it. This can be in the form of Steel Pipe Sheet Piles, or Pipe-Sheet Piles Combi Wall, Beam-Sheet Piles Combi Wall and Box Pile Configurations.
