In some cases traditional methods are still the best. Proven over the last hundred years, and using the latest tools and technology, timber headings and blind pipe jacks can solve some problems that other trenchless methods cannot. Whether it’s restricted space at the drive shaft or many services in the area, this is one of the best methods of tunnelling over short distances.
Timber Headings are a cost effective method for short tunnelled sections where microtunnelling equipment or other trenchless equipment does not prove possible or uneconomical. One of the main advantages is the ability to divert past any unknown obstructions and connect into existing services underground while maintaining standard operating conditions above surface.
Timber headings are constructed by hand using timber sets
to support the excavation and the pipeline is fed through the tunnel and grouted.
