Darlington Drilling and Piling are able to offer retaining wall services covering timber pole retaining walls, UC or UB steel pile retaining walls and driven railway iron retaining walls.
Driven railway iron retaining walls on rural roads or beside streams and rivers is a specialist area Darlington Drilling and Piling have perfected over the years. We can offer economic solutions including a design and build service. Retaining walls for urgent roadside slip repairs, developing the design as work proceeds, is something Darlington Drilling and Piling has a proud record of with a number of local authorities and government entities through the region.
For the more routine retaining walls we are happy to work with clients who want just poles their timber retaining wall supplied and installed in drilled concrete piles through to full pole wall construction and backfilling. We are also able to supply and install galvanised or specialist paint system coated UC or UB steel soldier pile walls with the UCs or UBs either driven or installed in drilled concrete piles. A range of timbering (lagging) options are available to suit the wall design.
We will drive UCs, UBs and railway irons for retaining walls as we can ensure adequate penetration into competent ground, with railway irons in particular able to be driven someway into rock while maintaining a satisfactory alignment, however will not generally drive timber poles for retaining walls. Our preference to ensure suitable embedment for timber retaining wall poles into ground competent of holding up a retaining walls is to install the poles in drilled concrete piles, in doing so we can also ensure alignment to a standard that is not able to be maintained when driving poles.
