Retaining walls were a fundamental item of our 'Garden Craft' landscaping projects in Wollongong and Sydney prior to GC Civil's establishment in 2002, and therefore our experience and knowledge of retaining walls is very extensive.

Common types of retaining walls built are block, koppers log, precast concrete panel (typically at the base of a noise wall), crib, rock/boulder, sandstone log, and gabion.

In all the years of building retaining walls, not one of our completed walls have failed; they are all built to a very high standard of quality and like all our services, they are built to last forever.
