Combined Walls

Combined sheet pile walls consist of bearing piles and intermediate piles, are used worldwide in heavy coastal engineering projects.

Large diameter piles can be used to build into a continuous combi wall either by installing steel piles together through interlocking clutches or by installing sheet piles in between the steel piles.

In combi wall, piles acts as the load bearing structure, while sheet piles installed in between make the wall continuous.

Combi wall is an effective and economical solution for a high section modulus requirement and often used in applications i.e. building foundation, bridges, wharves and piers.

We are capable to supply the complete solution from our partners overseas. Our steel piles can be manufactured by SSAW or LSW method in accordance to relevant standards i.e. ASTM A252 / API 5L /AS/NZS 1579 / AS/NZS 1163 with interlocking hot or cold rolled clutches welded in line with AS/NZS 1554.1 SP or AWS D1.1

Please refer to our complete range of hot rolled or cold rolled sheet pile options to complete your combi wall project.
