Horokiwi Quarry MSE Wall
Project Type
Retaining
Date
June 2025
Location
Horokiwi Quarry, Lower Hutt, Wellington NZ
Client
Fulton Hogan NZ
Tascon was engaged to deliver site retaining works and a significant portion of the foundation construction for a new asphalt plant at Horokiwi, Wellington.
The scope included the construction of a Mass Stabilised Earth (MSE) retaining wall along the front edge of the site, measuring approximately 65 linear metres in length and up to 7 metres in height. The works required around 2,000 m³ of excavation, with approximately 2,500 m³ of AP65 placed and compacted as engineered backfill behind the wall.
Delivered under challenging site conditions, with stringent health and safety requirements and a compressed programme, the project aligned perfectly with Tascon’s core strengths — technical civil construction, efficient delivery, and dependable outcomes on complex sites.
