Combined Walls | Oriental Sheet Piling

Pipe and Pile Diagram

Innovating at every opportunity, OSP is the pioneer for foundation projects involving both pipes and sheet piles.

Find out why our steel pipes can withstand such high lateral forces.

The pipe and pile combined wall system combines the best of both worlds from OSP’s foundation steel solutions: the primary pipe element being used to take the brunt of lateral force from soil and water, while having the shorter and lighter sheet piles to stabilise local soil mass between primary piles and transfer load.

The result? An effective weight foundation solution that handles high lateral force and vertical bearing capacity with ease.

HZ-M Walls

The revolutionary HZ-M wall is an extremely economical combined wall system, launched in 2008 by ArcelorMittal to replace the former HZ/AZ system. This typically consists of:
1. HZ-M king piles
2. A pair of AZ sheet piles as intermediary elements (the infill sheet piles)
3. Special connectors (RH, RZD, RZU)
The HZ-M king pile

This combination fulfils two different structural functions: they act as retaining members for soil and hydrostatic pressure while being bearing piles for vertical loads. More specifically, the intermediary sheet piles have a soil-retaining and load-transferring function and are generally shorter than the HZ-M king piles.

A variety of other combinations of sheet piles and foundation steel solutions can be incorporated together depending on the specific conditions and requirements of a project. Certain specific examples of past combinations include:
