At Earthwork Support Specialist (CE) Ltd, we design, supply, and install King Post wall systems with precision and reliability. Our in-house team brings decades of geotechnical expertise, delivering safe, efficient, and commercially sound solutions for projects across the UK.

King Post walls are a versatile and cost-effective method of earthwork support, suitable for both temporary and permanent applications. They are particularly valued for their flexibility, efficiency, and adaptability across a wide range of site conditions.

Key Benefits

• Ideal for vibration-sensitive environments.

• Practical for most ground conditions, with construction methods including open-bore, cased, or CFA techniques.

• Efficient use of steel and other costly materials.

• Multiple infill options such as timber, prestressed concrete panels, steel plates, and inverted sheet piles.

• Suitable for restricted access areas where larger piling rigs cannot operate.

• Can be installed tight to existing structures for maximum space efficiency.

How the System Works

The process begins by driving or boring into suitable ground conditions, installing a UC beam at predetermined centres. Infill materials are then fitted to complete the wall. A full engineering analysis is carried out beforehand to determine the correct post size, spacing, and design, ensuring the wall meets its intended application and retaining height requirements.
