Glenn Armstrong Agricultural Excavations is a family owned and operated business. Established 1988, we have a wealth of local knowledge of Far North Coast NSW and specialise in agricultural and permaculture excavations for all your farming needs. Much of our agricultural and permaculture earthworks involve constructing dams, swales and drainage, or cleaning out existing dams. We also conduct erosion control and landslip repairs. Let us help you with all your earthwork creations or dreams. We will work with your engineering or help you design your own earthworks.
