Eco-building materials · Made from diverted waste
Two steps off every wall you build.
ECOBLOCK interlocks, so courses align without a string line, and the moulded face is the finish — no plastering, either side. Same crew, same day, fewer trades. Manufactured from municipal waste recovered at our own facilities, to a tested 700 PSI.
01 · The range
Three families, one feedstock.
Everything here is manufactured from material recovered at a Nexuz Circular Economy Center. Custom sizes are cut to order.
Walls & structure
Commercial · residential · agricultural
ECOBLOCK structural block
Interlocking · self-finished
Alternative to conventional hollow block. The moulded face is the finish, so neither side needs plastering, and the interlock aligns each course without a string line.

Eco-Aggregate Series
Lightweight artificial aggregate
Structural aggregate engineered from recyclable waste, cutting dead load without giving up compressive resilience. For structural concrete, masonry units and precast.

Eco Paver — plain finish
Ultra-low water absorption
For high-traffic commercial and industrial zones where the surface has to be swept, washed and driven on. Outperforms standard concrete on compressive strength.

Eco Paver — rough & pervious
Slip-resistant · draining
Textured and permeable, so stormwater passes through the surface instead of pooling on it. Specified where runoff and standing water are the problem.

Slotted concrete post
Intermediary · four sections
Takes panels on both sides without brackets. Four square sections so the post is specified to the panel run and the exposure, not the other way round.

03 · The economics
Roughly 10% off, and almost none of it is the block price.
Compare on the wall, not on the unit. Four line items come off a conventional build, and three of them are labour and consumables.
No plastering
Both faces are finished out of the mould. That removes the plasterer, the cement, the sand and the cure days from between laying and painting.
Less mortar
A conventional hollow block has large voids, and every course loses bed mortar down into them. ECOBLOCK’s hollows are much smaller, so the mortar stays on the block instead of falling through it — less cement per square metre, and less of it swept off the slab at the end of the day.
Faster laying
Courses self-align, so a crew lays without a string line and without correcting drift. Same crew, more wall per day.
Fewer trades on site
The programme shortens where trades no longer have to queue behind each other — usually worth more than the material saving itself.
04 · Provenance
Every block has a catchment.
The material was your municipality's waste before it was your wall.
Mason Bee is the manufacturing arm of Nexuz Group. Feedstock comes from Circular Economy Centers we design, build and operate — municipal solid waste that was separated, washed, compounded and moulded within the same province it was collected in.
For a contractor that is a supply-chain fact: shorter haul, local availability, and a delivery note that says where the material came from. For an LGU buying back its own diverted waste, it is the point of the whole exercise.
And it does not have to carry our name.
Every product on this page can be supplied white label — your brand on the delivery, your logo on the documentation, and the diversion certificate issued in your programme's name rather than ours.
For a developer with a published sustainability commitment, or an LGU running its own green-build label, that turns a material purchase into a line in the programme. The waste diverted is counted against your target, and the wall it becomes carries your mark.
05 · Ordering
How buying works.
Quote against a schedule
Send a bill of quantities or a rough area and we quote to it. We would rather price your actual run than publish a rate that does not survive contact with your site.
Lead time follows the run
Stock lines dispatch from the nearest facility. Custom sizes and volume runs are scheduled into production and confirmed in writing before you commit.
Delivery from the nearest CEC
Freight is quoted from whichever facility is closest to site — one of the reasons a local catchment matters to the landed cost.
Test certificates included
Compressive strength certificates issue with delivery, so the material clears inspection without a separate testing round.
06 · Request a quote
Tell us the wall, not the block.
Area, run length or a bill of quantities — whichever you have. We quote landed to site from the nearest facility.
Quote request received.
We'll come back within 2 working days with a landed price from the nearest facility, and confirm lead time before you commit to anything.
What you get back
- A landed price — material and freight from the nearest facility, not an ex-works rate you have to add haulage to.
- A confirmed lead time — in writing, before you commit. Stock lines and production runs are quoted differently.
- Specifications and test certificates — so your engineer can approve the substitution before the order, not after delivery.
- A diversion figure — how much waste your order takes out of landfill, which counts toward EPR and ESG reporting if you need it to.
