Parallel shoring is the logical refinement of the slide rail system and is able to guarantee optimum performance and reliability, even in the most difficult ground conditions. Cracking and soil subsidence are both dramatically reduced. High strengths, system flexibility and user friendliness are main features and in stead of the fixed in position threaded spindles the double and triple parallel slide rails are connected by a heavy duty sliding frame that slides up and down within the slide rails. This design has the advantage of increased system strength and a dramatic reduction of soil subsidence which could otherwise cause damage to roads and nearby structures.
This system boasts the following features:

• Large maximum pipe culvert
• Restricted / extended trench width capability
• Extreme depth application
• Flexibility of system installation
