Block Quality

About Our Quality Control

We take quality control seriously. We grade Interbloc blocks into three quality bands based on;

  • Dimensional accuracy
  • Concrete strength
  • Aesthetics
  • Integrity of lifting pin

Our three quality bands are Premium, Basic, and Second. You can view the full quality band guidelines here.

Warranty Information

We offer comprehensive warranties on all our premium products, and limited warranties on basic products.

The standard solution to an manufacturing faulty is to replace that product with new. You can read our warranty policy here.

We are a building products supplier and we do not undertake installation work. As such our warranty is strictly limited to the replacement of blocks.

Guaranteed MPa Blocks

All our premium and basic products meet a minimum strength of 20MPa at 21 days.

About 50% of our blocks exceed this requirement. As such we can provide project specific minimum MPa blocks.

About Upcycled Concrete

Upcycled concrete is unused, uncured, ready mix concrete. It is the same concrete that is used in footpaths, building foundations, bridges etc. It’s simply excess to needs. It may be that a contractor wasn’t ready for the concrete, or too much was ordered.

Rather then letting it go hard and being sent to landfill – we capture the wet concrete and put it in our moulds.

Out of the mould comes a high quality precast concrete blocks manufactured using certified ready mix concrete from the countries leading concrete suppliers.

Block Buyback

Our approach to product design means that our blocks can have a use long after you no longer require them. Thats why we offer a unique Buyback Guarantee. It’s about making your life easier while helping the environment. It is essentially a second hand trading service, we take the blocks off your hands and offer them to our database of customers who prefer second hand blocks.
