Renolith™ is a patented polymer-based emulsion of latex, cellulose and nanoparticles. It is used as an additive to enhance soil-cement pavement construction and performance.

About Us

SINCE 1995

Wirtgen soil stabilizer

Context

Stabilisation is used to increase the mechanical performance of soils for the construction or rehabilitation of subgrades and pavements. This process can permit reduction in pavement depth and enable recycled, site-won, and lower grade materials to be used for pavement construction. However, cement-only stabilisation has application and performance limitations.

Renolith enables a long life, durable, impermeable road to be constructed from any in-situ soil using conventional stabilisation processes and machinery.

Renolith Product

Renolith™ is a patented polymer-based emulsion of primarily latex, cellulose and nanoparticles (aka: nanopolymer). It is used as an additive to enhance soil-cement pavement construction and performance. Road construction cost savings of up to 60% are achievable. 

Unlike other additives, Renolith:

  • inhibits crack formation and crack growth
  • is suitable for flexible pavements
  • can be used with any in-situ soil (or recycled pavement)
  • does not require periodic reapplication
NO RUTS. NO CRACKS. NO POTHOLES

Supply

Renolith is manufactured in Europe under an ISO-9001 compliant Quality Management System. It conforms to standard EN 934-2:2009. 

Grey Vort Pty Ltd, trading as Renolith (Australia) ABN 83 090 985 014, is the sole distributor of Renolith™ in Australia, NZ & PNG. Renolith™ is available in 5L sample containers and 1000L IBCs via renolith.com.au

Sustainability

Renolith Australia is committed to sustainability via a triple bottom line model:

  • People – better roads with less roadworks disruption.
  • Profit – pavements are cheaper to construct and maintain.
  • Planet – reduce materials use and carbon footprint.

Renolith can help improve a project’s Infrastructure Sustainability (IS) Rating. It enables roads to be constructed using 100% in-situ soils and/or recycled aggregates, thereby eliminating the need to mine, crush and transport vast quantities of virgin quarry material.

Renolith was originally developed as an admixture for Portland cement. However, cement production is energy intensive with a high carbon footprint. Subsequent research has confirmed its compatibility with pozzolans/Supplementary Cementitious Materials (SCMs) such as fly ash, lime, GGBS, glass powder, and volcanic ash. It is effective in mix designs using lower-carbon binders (eg. Blends incorporating cement and recycled SCMs such as slag or fly ash).

Research

The behaviour of Renolith in civil applications has been characterised in dozens of laboratory reports, field trials and research papers.

Renolith Australia is committed to an ongoing research programme to support pavement designers, project managers and construction contractors. The Civil Engineering departments at RMIT University and Flinders University have been engaged to support the programme.

Renolith Timeline

Invented and originally patented in 1995 by German nanotech laboratory.First major project: Sydney 2000 Olympics

1990's

Renolith used successfully in hundreds of projects across the globe, in every climate, with many different soil types.  

2000's

Next generation Renolith 2.0 formula developed.

2010's

Renolith 2.0 poised to transform global road construction processes to a sustainable and low-cost model.

2020's

Genuine Renolith™

We only sell genuine Renolith conforming to the patented formulae.

Fake products were sold in some markets including Australia under names such as “Renolith WS” and “Renolith WP” from circa 2000 to 2015. These products did not conform to the patented formula. Pavements using these fakes often cracked. 

Genuine Renolith:

  • Is safe to handle;
  • Contains cellulose to improve flexural strength and inhibit crack formation and crack growth;
  • Incorporates proprietary nanotechnology to improve density, impermeability, ettringite formation, CSH-binding and cross-linking;
  • Is effective at high binder contents without susceptibility to cracking; and
  • Is suitable for flexible pavement applications.
