Rivenhall Western Slope

At Rivenhall Western Slope, our team was tasked with stabilising and regrading a large embankment composed of loose, wet quarry material to support the ongoing construction of the Integrated Waste Management Facility (IWMF). These works were critical to ensuring a secure, durable foundation adjacent to the active quarry and to establishing permanent access infrastructure for the IWMF. The project required meticulous excavation, soil nailing, and re-compaction using clay arisings from the IWMF bunker, producing a stable slope and an essential access route to support the facility’s long-term operational needs.

The Rivenhall Western Slope is located on a greenfield site adjacent to both a live quarry and the main IWMF construction area, necessitating strict safety protocols and coordination to prevent disruption to ongoing quarry operations. The Western Slope was initially formed of loose, wet quarry material, which was excavated and removed to improve stability. This material was replaced with primary clay arisings from the IWMF bunker, compacted to form a more solid, durable embankment that will endure under future site conditions.

To further stabilise the embankment, our team employed soil nailing techniques, enabling the slope to be steepened while ensuring structural integrity. These soil nails were installed systematically to reinforce the earthworks and provide long-term stability against environmental and operational pressures.

An integral part of the project was the construction of the main permanent access road. This road is equipped with a comprehensive drainage system and service ducting to manage water runoff and support future utilities for the IWMF facility, ensuring accessibility and durability throughout the life of the facility.

Working alongside a live quarry and the primary IWMF construction area introduced logistical and safety challenges. Our team implemented a rigorous safety and communications plan, working closely with the quarry’s operations team to coordinate schedules and minimise any potential interference with daily operations. Through careful planning, we mitigated the environmental impact of the excavation works and implemented measures to reduce dust and noise, contributing to a safe, efficient work environment.
