Solutions for confined spaces

Grouted mini-piles
Grouted mini-piles are a foundation solution when there isn t much space or there is low headroom. We have successfully used them for over 25 years. They are typically used to underpin or strengthen existing structures, internally or externally.

This type of pile uses a drill head, rather than an auger. As the pile is drilled into the ground, it injects grout into the surrounding soil to bond the pile to the surrounding ground.

There are a number of advantages in using grouted mini-piles. They can be used in difficult or variable ground conditions. They can be used within existing buildings, causing minimal disruption.

Bored mini-piles
Cementation Skanska offers a full-range of mini-Piling services. As well as conventionally powered mini-piling rigs, we operate electric rigs. These can be used in very confined spaces without exhaust emission issues.

The diameter and depth of mini-piles are determined by two factors. These are the ground conditions and the size of the rig which can access the location where the pile is to be drilled. For this reason, it is essential to discuss the design details at an early stage.
