Precast concrete products

A history of service

Since 1932, Larsens have precast water tanks, troughs, septic tanks and most common farm and home concrete products. The company’s philosophy of offering quality products at a fair price has continued for the last 85 years to remain a cornerstone of the business.

In 1992, Pamela and Ian McDonald purchased Walter Larsen & Sons Ltd and revitalised the business and product lines. Founded on innovation, the Walter Larsen & Sons Ltd Company is now McDonald Concrete Group Limited.
