These best endeavours are strictly limited to the above ground structure (commonly the blocks any any vertical reinforcing requirements). Under no circumstances will Envirocon provide any warranty as to the suitability or structural integrity of the foundation or sub-base. It is ultimately the customer’s responsibility to seek independent engineering designs and calculations on foundation requirements. 

Envirocon does will not provide any warranty for the installation of the structure, even where training and demonstration services have been provided. 


If Envirocon has reasonable cause to believe that the customer has breached these terms, has committed or will commit an act of bankruptcy, has had or is about to have a receiver or liquidator appointed, or is insolvent, Envirocon may (without prejudice to its other rights) withhold supplies of further products or services to the customer (whether under these terms or any other agreement or arrangement) without notice, demand any form of security for the customer and to secure the customer’s obligations under these terms, and/or recover and/or resell any of the products and enter into any premises where it believes the products are located, and the customer grants Envirocon the irrevocable right and authority to do so. Envirocon may recover and resell only sufficient products to satisfy all unpaid liabilities.

The customer warrants that it has full authority to authorise Envirocon to install any product installed by Envirocon at the customer’s request.

Such indemnity extends to reasonable legal costs incurred by Envirocon arising out of the claim by the third party.

The customer shall provide Envirocon full access to premises in which products are to be installed, and adequate power, lighting, and other facilities to allow Envirocon to install or service products. Envirocon may make further charges to the customer should there be any delay, or additional attendances as a consequence of lack of access to facilities, or lack of adequate facilities.

The customer will advise Envirocon if it is necessary for Envirocon to co-ordinate with any other trade persons.

Envirocon’s Buyback Guarantee is all about making your life easier.

Envirocon offer two types of freight options.

OPTION 1: Envirocon Organised Delivery
OPTION 2: Customer Organised Pick Up

These guidelines outline the terms and conditions of each type of freight option.


The price of freight will be automatically calculated at the point of purchase on the e-commerce platform. The price of freight is determined by a combination of the weight of the product, the volume of product, and the delivery location. Freight pricing is subject to change at any time without prior warning.

For 600 and 400 Series blocks, Envirocon will deliver the blocks on a flat deck or curtain side trucks. The customer needs to ensure they have appropriate equipment (forklift or similar) to offload the blocks on arrival.

For Unibloc Series blocks Envirocon will deliver the blocks on a flat deck, curtain sider, or ute. The customer needs to ensure they have appropriate equipment of labour power to offload the blocks on arrival.


Dunnage is material (wood) stowed under blocks to prevent damage or instability during transport.

All flat bottom blocks must be transported using dunnage; standard dunnage measures 100mm x 100mm x 2400mm wooden dunnage. Envirocon automatically includes the cost of dunnage into the price of Flat Bottom blocks.


Clear site access is essential to the smooth delivery of blocks. When establishing whether there is clear access to site customers should keep in mind blocks are transported on large trucks, often fully loaded and weighing in excess of 33 tonne. The following should be considered when assessing site access:

NB: Delays caused as a result of the site not complying with the above guidelines will result in extra charges being passed on to the customer.


Where the customer opts to collect the blocks the following terms and conditions apply.

  1. There is a minimum 24 hour notice period between the placement of order and the customer arriving on site to collect blocks. Any variation of this stand down period must be agreed with Envirocon.
  2. Envirocon’s Dispatch Manager will make contact with the customer on placement of the order to organise a collection time.
  3. Blocks will be collected from Envirocon’s Penrose Collection Plant located at 667b Great South Road, Penrose. On arrival the customer must report to the office, with a copy of the order confirmation.
  4. For 600 and 400 Series blocks, Envirocon will only load the blocks on a flat deck or curtain side trucks. The customer needs to ensure they have appropriate equipment (forklift or similar) to offload the blocks at there site.
  5. For Unibloc Series blocks Envirocon will load the blocks on a flat deck, curtain sider, or utility vehicle. The customer needs to ensure they have appropriate equipment of labour power to offload the blocks.
  6. The customer must supply their own load constraints and dunnage;
    1. Blocks must be tied down to the deck.
    2. It is expected that land transport regulations are complied with. Where chains are used edge protectors should be used between the chain and the edge of the block to prevent damage to the block.
    3. It is the responsibility of the customer to ensure they comply with all regulatory requirements, including all applicable NZTA requirements.



The movement of the truck while in transit can result in minor chipping of the blocks. This is largely unavoidable. Envirocon does not take responsibility for chipping of blocks in transit, or during the offloading of blocks by the customer.


Envirocon block weight between 30kg and 1500kg. As such it is important to ensure appropriate lifting gear is available. There are multiple ways of lifting the blocks depending on the requirements of individual projects, the type of truck freighting the blocks, and the ground conditions at site.
