Transport Guidelines


Envirocon has a number of core services and procedures related to the movement of blocks. We offer our customers two options when it comes to freight:

OPTION 1: Envirocon Organised Delivery


OPTION 2: Customer Organised Pick Up

These guidelines will introduce you to the minimum requirements for each transportation option to ensure all deliveries occur on time, and in a cost effective way.



• Cost savings through Envirocon buying power

• Greater flexibility on delivery times

Envirocon will offer to organise delivery of blocks to site, however the customer will be responsible for offloading the blocks at site. This is the perfect option for customers who intend to install the blocks themselves.

How does it work?

1. Request a Quote – The freight price shown on the quote will be for Envirocon Organised Delivery only.

2. Accept the Quote – By accepting the quote you agree that to comply with Envirocon site access and unloading requirements outlined below. Any delays may result in extra charges for the customer.

3. Organise Delivery Dates – Your Envirocon rep, and Envirocon’s freight supplier will work with you to organise a delivery time. All site access requirements and guidelines are outlined below apply. If there are any special requirements relating to your site customers will need to raise this with your Envirocon rep to ensure deliveries comply with requirements.

4. Customer Offload Blocks – When the blocks arrive to site it will be the customer’s responsibility for offloading the blocks. To minimise chipping while offloading blocks Envirocon strongly recommends customers use lifting equipment as outlined in the guidelines below. Included in the price of delivery is 45 minutes wait time to offload blocks. Waiting longer than 45 minutes will incur extra costs which will be passed on to the customer.


From time to time customers will opt to pick up the blocks from an Envirocon manufacturing yard. Envircon is able to accommodate such requirements.

How does it work?

1. Accept the Quote – When accepting a quote specify to your Envirocon rep if you intend organise the delivery of the blocks to site.

2. Dispatch Dockets – All pick-ups from a Envirocon yard require a dispatch docket, you will receive this from your Envirocon rep. The truck driver picking up the blocks will need to present a copy of this when arriving at site. Organise with your Envirocon rep an expected pick up date.

3. Pick Up – Before arriving at site the truck driver will be required to call the yard dispatcher (the number will be listed on the dispatch docket) to inform them of an expected arrival date. The Truck driver will be required to comply with all Yard Health and Safety directives. The truck driver will also be required to supply dunage as outlined below.

Where the customer opts to customer organised pick up, Envirocon warrants the blocks and condition of the blocks only up to the stage they are loaded onto the truck. All customer organised pick-ups are subject to yard operating requirements.

Envirocon recommends the following guidelines for customer organised pick ups:


Envirocon blocks will only be loaded on to a flat deck, or curtain sider truck. Careful consideration needs to be given to how the blocks will be unloaded when selecting transport type.


– When loaded at an Envirocon manufacturing yard, loading must be completed by a Envirocon staff member.

– The truck driver is ultimately responsible for the distribution of the load across the deck, and should direct the machine operator on where to place blocks.

– Consideration should be given to the size and weight of blocks when placing loads. 600 Series Blocks can be placed four across on a standard 2.4m wide deck, 400 Series are stacked on pallets allowing for two pallets across a deck.

– The interlocking recesses at the bottom of standard 600 series blocks provide natural lugs for forks to lift the blocks. Providing the lifting capacity of the forklift allows, standard 1200 blocks may be loaded two at the time.

NB: Forks thicker than 50mm (common on forklifts above 2.5t) will bind in the fork slot and will damage the lower edge of the block.


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.

– It is the responsibility of the transport operator to provide dunnage which conforms to Envirocon requirements. Failure to provide dunnage, or the correct size of dunnage will result in Envirocon charging for the supply of dunnage at the cost of $7.50 per piece.


– Blocks must be tied down to the deck.

– 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.

– It is the responsibility of the transport operate to ensure they comply with all regulatory requirements, including all applicable NZTA requirements.


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:

• Access – Average width of trucks transporting blocks are 2.5m wide. Access should be a minimum of 3m wide. Ensure over hanging trees, plants, or other obstacles are either cleared in advance, or are sufficiently high enough for trucks to pass under.

• Turning – Trucks will require sufficient space to turn on site. It is the customer’s responsibility to notify their Envirocon rep if turning space is limited.

• Unloading – The most efficient way of unloading blocks is to unload blocks two at a time from either side of the truck deck. This requires a minimum of 6m clear space on either side of the truck to provide a sufficient and safe working area.

• Stacking Blocks – After being unloaded the blocks are required to be stacked in preparation for use in the structure. Good ground conditions may allow for blocks to be stacked 3 high. Stacking blocks as close to the final place of installation reduces installation times and minimises the need for double handling and potential damage. As a general guide for 3 blocks storage space of 1.5m2 is required.

• Ground Conditions – Good access requires firm level ground, capable of
bearing the weight of a fully loaded truck and trailer. Where weather causes ground conditions to change your Envirocon rep should be notified immediately.

• Gradients – Where access to site is via ground of varying gradients the customer must ensure it is passable by a fully loaded truck. Steep gradients, or incorrect prepared roads can result in an inaccessible site.

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.


The movement of the truck while in transit can result in minor chipping of the blocks. This is largely unavoidable, however in cases where it is essential to maintain the aesthetics of the block, blocks can be loaded on a truck with greater space between each block. This will result in increased freight costs. Customers who require this service should discuss this with their Envirocon rep.

At Envirocon we make every effort to minimise chipping. For this reason we require flat bottom blocks to be loaded on dunnage.

Envirocon does not take responsibility for chipping of blocks in transit.


Envirocon block weight between 300kg 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.

"We had a small crisis at work, our loading bank for chip and residues was falling. The would stop our operation. The team at Interbloc gave us a solution that we could dismantle and rebuild our wall in 1½ days. The advice was good, the service prompt and the result was great. I would recommend Interbloc when you need a fast, stable wall for a competitive price."
