Brief Bio

Previously Greg Sieders was the Regional Business Manager – Asia and Americas of Bluey Technologies and was with the company for close to 13 years.

Since completing his education, Greg has had a work history spanning more than 20 years in large civil engineering and building projects.  Through his employment by major technology suppliers including BASF, EWS and Bluey, Greg has gained a wide range of product development and site application experience.  His knowledge includes cement and resin based systems, corrosion protection and various types of ground support.  

The combination of his experience and knowledge has prepared Greg to be instrumental in the development of new cable rock bolt designs for tunnels and also the increasingly prevalent use of GRP systems for permanent ground support applications.  Greg worked closely with both in-house Bluey Engineers and external consultants to ensure new design solutions developed by Bluey can be adopted on site with practical application advantages.

Greg was instrumental in the growth of Bluey Technologies which has rapidly expanded to become a reputable construction material supplier throughout Australia, New Zealand and South-East Asia.

Abstract

Lightweight Cellular Grout (LCG) Solutions for Civil Engineering Applications

This presentation explores lightweight cellular grout (LCG) as a sustainable, cost-effective alternative to conventional construction materials. The focus is on three key applications:

1. Retaining Walls for Slope Stabilization– Replacing no-fines concrete with LCG to reduce material usage, improve workability, and enhance drainage performance.
2. Road Pavement Subbase– Utilizing LCG as a lightweight, stable subbase to minimize settlement and improve load distribution.
3. Reinforced Earth Walls– Substituting compacted soil with LCG for faster installation, reduced labor requirements, and improved cost efficiency.
