Chambers Flat Road Widening: Overcoming Soft Subgrade with mastaTEX®

Chambers Flat mastatex

See Civil recently undertook a challenging project involving road widening and the construction of a new bridge on Chambers Flat Road, Chambers Flat. However, the project faced a significant obstacle in the form of unsuitable ground conditions, particularly regarding road base compaction.

Overcoming Soft Subgrade for Road Base Compaction

The existing soft subgrade posed a major hurdle in achieving the required compaction for the new road base. Traditional methods risked intermixing of the granular base materials with the subgrade. This could have compromised the road’s structural integrity and potentially led to surface issues like rutting and deformation.

Innovative Solution with mastaTEX® (PET) and mastaGRID® GT

Understanding the project’s urgency, Polyfabrics responded swiftly with a solution – readily available stock of mastaTEX® (PET) Non-Woven PF44 and mastaGRID® GT Geogrid.

  • mastaTEX® (PET) Non-Woven: This innovative geotextile served as a separation layer between the new road base and the subgrade. mastaTEX® enabled optimal compaction by preventing intermixing, resulting in a resilient and long-lasting road surface.
  • MastaGRID® GT Geogrid: This biaxial geogrid helped stabilise the road base during excavation and widening – especially in areas with unsuitable ground. mastaGRID® GT reduced road base height while achieving design compaction levels. Its availability for same day delivery helped the project meet tight deadlines due to rain delays.

Benefits of mastaTEX® (PET) Non-Woven and mastaGRID® GT for Road Construction:

  • Immediate Availability: Polyfabrics’ well-maintained inventory ensured minimal project delays due to material procurement. This was particularly crucial during unpredictable weather conditions, keeping the project on track.
  • Enhanced Road Base Performance: The geotextiles and geogrids effectively separated the subgrade from the road base, preventing material intermixing and promoting optimal compaction. This resulted in a long-lasting road surface with superior structural integrity.
  • Technical Expertise: Our in-house technical team provided valuable advice on proper mastaTEX® and mastaGRID® GT usage. This ensured the geotextile and geogrid’s effectiveness and maximised project success.

Additional Solution: TerraDrain® Sheet Drain for Bridge Embankment Drainage

Due to the wet weather forecast, a quick and easy solution was needed to collect and divert water on the bridge embankment. Polyfabrics recommended TerraDrain® Sheet Drain, a dimpled plastic sheet that provides effective drainage and waterproof membrane protection. This TerraDrain® s integrated non-woven geotextile covering prevents soil particles from blocking the drainage while allowing water inflow. Its dimple structure effectively captures and transports high water volumes. TerraDrain® was readily available to meet project requirements with staged deliveries.
