Foundations for 70 Homes Delivered Ahead of Schedule – The Broyle

At The Broyle development in Ringmer, near Lewes, ground conditions presented several challenges that required the right foundation solution from the very start.

Across the site, the topsoil was highly variable, consisting of gravelly sandy and silty clay layers. These changing geological conditions meant the foundations had to perform reliably across inconsistent ground.

To add further complexity, several plots were located within areas of tree influence, meaning heave protection measures were essential to protect the structures long term.

Our engineered solution was a mixed voided and non-voided piled raft foundation system, specifically designed to manage the site’s challenging ground conditions while delivering long-term structural stability.

In total, the project required 3,886m² of structural foundations, made up of 32 raft foundations supporting 70 residential properties — all delivered within a 14-week construction programme.

Located in the village of Ringmer, just outside the historic town of Lewes, The Broyle is a carefully planned development of 70 homes designed to complement its semi-rural setting.

But before the homes could take shape above ground, it was essential to get the foundations right below it.

More than 70% of the works took place during the wettest months of the year, often in heavy rain. Thanks to the piled raft system, the programme continued moving — where traditional foundation methods may have required waiting for drier conditions.

Given the weather and site conditions, completing the project on time was no small challenge. Yet the team delivered the foundations three days ahead of schedule.
