Results

  • Fire-damaged retaining wall safely remediated, protecting the property above from future instability.

  • Slopes stabilised and naturally regenerated vegetation, reducing long-term erosion risk.

  • Innovative two-tiered retaining solution delivered within tight site constraints.

  • Integrated soil nailing, shotcrete, and micropile techniques provided a durable and cost-effective outcome.

Project

Solution

  • Designed slope-specific stabilisation using soil nails, high-tensile rockfall netting, and erosion control matting.

  • Delivered erosion control that promoted natural revegetation without hydro-seeding.

  • Constructed a lower retaining structure with soil nails and shotcrete, backfilled with stabilised sand to create a stable platform.

  • Rebuilt the upper retaining wall as a precast concrete panel wall supported by a strip footing and series of micropiles.

  • Combined geotechnical and structural systems to ensure stability, longevity, and minimal site disturbance.

Project

Challenges

  • Fire damage had compromised an existing retaining wall, increasing risk of undermining property above.

  • Restricted space at the site meant traditional retaining wall construction methods were not feasible.

  • Requirement to stabilise slopes prone to erosion while enabling long-term natural regeneration.

  • Need to design and integrate two retaining solutions within limited footprint.

Project

Overview

Geovert was engaged to stabilise fire-damaged slopes and an existing retaining wall at risk of undermining a property above. Using available geotechnical information, the team designed site-specific soil nailing and erosion control solutions, applying high-tensile rockfall netting and erosion control matting. Vegetation successfully regenerated naturally in a short time, enhancing long-term slope stability. 


A two-part retaining solution was engineered to address the damaged wall: a soil nail and shotcrete structure forming a stable base, and a precast concrete panel wall supported by micropiles to provide permanent protection.
