PP Non-Woven Geotextile
As an alternative to hard-engineered structures like rock walls and gabion baskets, AWB offers effective soft solutions for erosion control and stabilisation.
Increasingly, communities and engineers are choosing adaptable, sustainable systems that work with the environment. Our goal is to provide a cost-effective, flexible coastal erosion control system that protects landscapes while supporting natural regeneration.
Our Services
At AWB, we provide innovative and sustainable erosion control and civil engineering solutions designed for New Zealand’s unique landscapes. From protecting fragile coastlines to supporting major infrastructure and land development projects, our systems are engineered to deliver strength, stability, and long-term environmental benefits.
Whether it’s stabilising sand dunes, reinforcing riverbanks, managing stormwater, or supporting large-scale construction, AWB’s proven geotextile and sandbag systems are trusted nationwide to perform in the toughest conditions.
Coastal Erosion Protection
Coastal erosion is a natural process that can have serious impacts on exposed shorelines. AWB’s specially engineered geotextile bag system is designed to stabilise vulnerable areas, strengthen sand dunes, and encourage natural regeneration of both sand and coastal vegetation. This provides a sustainable, long-term solution for protecting New Zealand’s coastal landscapes.
Civil Contracting
Our systems can be used for a wide range of infrastructure and civil works, including in-situ stabilisation, bridge support, pavement and road maintenance, and ground improvement projects.
Land Development
AWB supports complex infrastructure needs for both residential and commercial subdivisions. Our solutions assist with stormwater treatment areas, drainage structures, aggregate spillways, weirs, fish passages, and native re-vegetation landscaping—helping developers build resilient, sustainable environments.
