A Farmtrac GPS map of the drainage installation is supplied with every job. This provides a record of this valuable buried asset and helps easily locate the pipe for system extensions and maintenance

Reconstruct your race without importing metal.

Save on transport costs, reduce lameness, reduce mastitis, reduce dust, increase profits.

" I have been very impressed with Road Packer products. The treated dairy farm races have held together well through a particularly wet season and still look as good as when they were first laid down. Track maintenance has always been an ongoing job but with the Road Packer products I am impressed with its durability and therefore its lesser costs. The product and process of the work on these tracks seems to bind the fine materials together and act as a cap, preventing the water getting into the metal, preventing bog, which in turn has reduced lame cows significantly. Less lame cows equals more profit and more time on productive work "

Blackley Construction Ltd have undertaken a number of small and large farm irrigation projects from private land owners to Fonterra Co-operative Group.

We work with water supplies of all sizes and materials.

We have been involved in the laying of standard installations for subdivisions through to special installations involving water filters, meters, pumps and specially fabricated pipe work.

We have installed more than 100,000m of pressure pipe for fixed effluent irrigation systems.


Blackley Construction Ltd has over the years constructed numerous horse arenas for both recreational and commercial use.

Whether the arena is for private use by family and friends, clubs, professional horse trainers or for riding for the disabled ventures, Blackleys can offer the appropriate conduction solution.

It is very important to have an arena surface and base that is specifically matched to the end use.

There are a number of factors that need to be defined to ensure the longevity of the surface and the safety of the horses. Discussions prior to construction with the potential users will provide the best end product and value for money for the client.

Blackleys use a variety of products and methods to best suit each situation.
