OVERVIEW

Envirocon produces two core block families – Interbloc and Stonebloc. Each family has distinct applications and characteristics. Blocks are graded into quality bands according to the blocks suitability for the intended application. These guidelines outline our quality standards.

 

Interbloc:

Interbloc is primarily designed to provide structurally sound bulk storage and retaining wall solutions. The product is inherently industrial looking, therefore quality control is focused on the structural integrity of the block. There are three core quality bands for Interbloc – Premium blocks, Basic Blocks, and Second Blocks.

 

Stonebloc:

Stonebloc is a residential retaining wall solution. It is designed to provide a efficient, durable retaining wall solution with a superior aesthetic when compared to timber wall. As such our quality control is focused on both the structural integrity of the product and aesthetics of the block. There are two quality bands – Premium and Second.

INTERBLOC QUALITY BANDS

Premium Quality Blocks

Guiding Statement: Blocks are both structurally sound and largely free of chipping.

Product Code Designation: ‘E’ – for example 6IB-1200EStd-G.

Colour Designation on Block: Green dot.

Concrete MPa: Greater then 20MPa

Dimensional Accuracy: Within 3mm of true to size on each side of block.

Reinforcing Holes: Are clear, and straight.

Block Aesthetics: No cold joint split pours. No split pours of different colours. Block chipping is less then 10mm wide or 10mm deep. No more then two edges with chipping on either face of the block. No gaps or air bubbles on the face of the block.

Block Colour: Largely consistent colour across all blocks dispatched in the order. Some tonal variation may apply – for example slightly different greys across the concrete range.

Lifting Anchor: Sitting correctly and able to be grappled with a Klaw.

Basic Quality Blocks

Guiding Statement: Blocks are structurally sound.

Product Code Designation: ‘B’ – for example 6IB-1200BStd-G

Colour Designation on Block: Yellow dot.

Concrete MPa: Greater then 20MPa

Dimensional Accuracy: Within 6mm of true to size on each side of block.

Reinforcing Holes: Are clear.

Block Aesthetics: Blocks may be split pours with internal reinforcing. Block chipping is less then 50mm wide or 50mm deep. No more then three edges with chipping on either face of the block. May have gaps and air bubbles on the face of the block.

Block Colour: Mixed colour blocks are possible.

Lifting Anchor: Sitting correctly and able to be grappled with a Klaw.

Second Quality Blocks

Guiding Statement: Blocks have extensive damage or may not be easy to use.

Product Code Designation: ‘S’ – for example 6IB-1200SStd-G

Colour Designation on Block: Orange dot.

Concrete MPa: Greater then 10MPa

Dimensional Accuracy: Within 12mm of true to size on each side of block.

Reinforcing Holes: May be blocked.

Block Aesthetics: Blocks may be split pours without reinforcing. May have extensive chipping across all faces and edges of the block. May have gaps and air bubbles on the face of the block.

Block Colour: Mixed colour blocks are possible.

Lifting Anchor: No anchor warranty in all circumstances. May not have a lifting anchor.

STONEBLOC QUALITY GUIDES

Premium Quality Blocks

Guiding Statement: Blocks are both structurally sound and look good.

Product Code Designation: ‘E’ – for example 4SB-800EStdT-G.

Concrete MPa: Greater then 20MPa

Dimensional Accuracy: Within 3mm of true to size on each end of the block.

Block Aesthetics: No cold joint split pours. No split pours of different colours. No block chipping on front face of block. No more then two edges with chipping on back face of block. No gaps or air bubbles on the face of the block.

Block Colour: Largely consistent colour across all blocks dispatched in the order. Some tonal variation may apply – for example slightly different greys across the concrete range.

Lifting Anchor: Sitting correctly and able to be grappled with a Klaw.

Second Quality Blocks

Guiding Statement: Blocks are both structurally sound but may have some chipping, or variation in texture on the face of block.

Product Code Designation: ‘S’ – for example 4SB-800SStdT-G.

Concrete MPa: May be less then 20MPa

Dimensional Accuracy: May not be dimensionally accurate.

Block Aesthetics: May be split pours. May have extensive chipping or other errors in the facial texture. May have air bubbles.

Block Colour: May be different colour blocks.

Lifting Anchor: No lifting anchor warranty.

EXTRA INFORMATION

The quality of the block is measured at dispatch. Envirocon will not take any responsibility for damage during transport or unloading.

Where the final aesthetics of a wall are critical, it is important to remember that Interbloc is an industrial looking product. Envirocon can provide advice on options for post installation veneers.

As per Envirocon’s Terms of Sale, remedial action for block quality disputes is the replacement of blocks.

EFFECTS OF TRANSPORT ON QUALITY

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, or during the offloading of blocks by the customer.

"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."
