Gabbro refers to a large group of dark, coarse-grained, intrusive mafic igneous rock chemically equivalent to Basalt. Because of its special hardness and strength, chemical and physical properties, Gabbro is a very suitable material for a wide range of construction and engineering projects.
With a deep knowledge of the technological processes and properties of Gabbro, United Quarries produces a range of standard aggregate and rock products.
