Specialist piling for difficult-to-reach and constrained sites
Restricted-access piling allows specialist foundation works to be undertaken where conventional piling equipment cannot practically reach or operate. Constraints may include narrow entrances, existing buildings, limited headroom, small working areas or difficult routes between the site entrance and the required pile locations.
Rather than referring to one specific piling technique, restricted-access piling involves selecting suitable plant and foundation methods around the physical limitations of the project. SPS can review access dimensions, structural requirements and ground conditions to identify practical options that deliver the required foundation performance while working within the available space.

How Restricted Access Piling Works
The first stage of a restricted-access project is understanding the physical constraints of the site. Access width, headroom, working platform dimensions and the route available for equipment and materials all influence which piling systems can be considered.
Once these constraints are understood, suitable compact plant and piling methods can be assessed alongside structural loads and ground conditions. This allows the foundation solution to be developed around both the technical requirements of the structure and the practical realities of the site.

Frequently Asked Questions
How do I know whether my site counts as restricted access?
Common constraints include narrow entrances, low headroom, limited working areas or difficult mobilisation routes. Photographs and dimensions can help SPS assess the site.
What piling methods can be used on restricted-access sites?
The available options depend on structural loading, ground conditions and the particular site restrictions. Mini piling, screw piling and other specialist systems may be considered.
How much access does piling equipment need?
There is no single minimum dimension because different rigs and piling methods have different requirements. Access width, height, turning space and working area should all be reviewed.
Can restricted-access piling be used inside existing buildings?
Potentially, yes. The available headroom, ventilation, working space, structural constraints and method of installation all need to be assessed.
