Isaac Construction Company – Plant Expansion

About the Customer

Since 1950, Isaac Construction has helped build the South Island by continually improving its infrastructure and environment. The right people, for the right result. As part of the Isaac Group they believe in delivering the best civil solutions, whilst everything they do is for the betterment of the community and the regional environments they operate within.

Isaac’s quarry products include concrete aggregates, sand, asphalt, roading, drainage aggregates, ice grit, cement stabilised products right through to topsoil.


Following the 2014 Christchurch earthquakes, Isaac was looking to expand in order to supply the development requirements of the city. So, a decision was made to invest in a major upgrade to the plant in order to satisfy this demand.

Stage 3 – Secondary Crushing Circuit and Cone PAP production

Stage 4 – Tertiary Crushing Circuit, Barmac PAP production and Sealing Chip Screens
