MEKA & CDE Modular Systems – Delivered and Supported by Rocktec
Rocktec supplies high-performance wash plant systems from MEKA and CDE, two globally trusted leaders in wet processing technology. Whether you’re recovering sand, cleaning aggregates, or managing sediment-heavy waste streams, our systems are engineered for efficiency, compliance, and long-term value.
From compact modular setups to full-scale turnkey plants, we work with quarries, mines, and recycling operators across New Zealand to design smarter, more sustainable washing solutions — built to perform and backed locally.
The right wash plant doesn’t just clean material — it adds value. Let’s build one that works for your site.
Why We Deliver Wash Plants
Washing is where value is recovered — and too often, it’s where efficiency is lost. At Rocktec, we specialise in wash plant solutions because we know how critical clean, in-spec material is to your operation.
We’ve built wash plants across New Zealand that do more than just meet spec — they reduce waste, optimise water use, and keep production moving.
Our difference:
-
Decades of wash plant delivery across NZ
-
Solutions tailored to local materials and regulations
-
Global technology (MEKA + CDE), locally integrated
-
End-to-end service from concept to commissioning
We build wash plants that perform — because performance is what matters.

How Wash Plants Add Value to Your Operation
Improve Product Quality
Wash plants remove silt, clay, and other contaminants, delivering clean, in-spec sand and aggregates that meet grading and moisture requirements for concrete, asphalt, and export use.
Recover More Material
Efficient fines recovery systems help reclaim usable material from waste streams — turning what would be lost into saleable product, improving yield and profitability.
Reduce Water Usage
With integrated systems like thickeners and filter presses (especially via CDE), wash plants allow water to be recycled and reused, cutting consumption and helping meet environmental compliance.
Lower Operational Downtime
Modular wash plants like MEKA’s are easy to maintain, with fewer moving parts and accessible layouts — meaning less unplanned downtime and more time producing.
Support Compliance and Sustainability
Cleaner output, less sediment runoff, and smarter water management help operators stay ahead of regulatory pressure and demonstrate environmental responsibility to stakeholders.
