JK Williams Rely on GEOmasta for Caddens Hill Project

Caddens Hill Estate Project
JK Williams, March 2019

PROJECT SNAPSHOT

Our customer JK Williams has been heavily involved in delivering releases 1 through to 6 of the Caddens Hill Estate residential project. When topsoil was carved back during the final stages of the project, workers exposed soft ground unsuitable for road paving. A specialist geosynthetic was required and Jaybro was able to supply mastaGRID Composite within just hours of the request, ensuring the project could continue within strict time frames.

THE CHALLENGES

After heavy involvement in the Caddens Estate Releases 1,2,3,4,5 and 6, JK Williams was called on for the last stage of Penrith’s newest suburb.

The final landscaping works across the sites gently rolling hills included tree protection and erosion control for the many embankments. Additionally, JK Williams needed to stabilise and reinforce road pavements near the eastern end of O’Connell Lane.

However, once the topsoil was carved back, soft and unstable ground with a poor bearing ratio was exposed where the road runs closely beside a bio basin. This provided some difficulty for the contractor, and a geosynthetic solution was required.

JAYBRO’S SOLUTION

The project managers reached out to the GEOmasta specialist team for assistance. Within just two hours of receiving the request, GEOmasta had 3000 square metres of mastaGRID composite 30/30 on site, saving the contractor time and money.

mastaGRID Composite 30/30 is a polypropylene geogrid heat bonded to mastaTEX Non-Woven geofabic. In using this product, the contractor was able to stabilise and reinforce the pavement and provide separation to the soft soils below.

Jaybro has had the privilege of being involved in the supply of a number of products throughout the Caddens Hill project. Our high-quality geosynthetic range combined with exceptional service was a key factor for JK Williams, and the ability to supply lightning fast meant that there was no disruption to works and the project could be delivered on time and on budget.
