Rock Anchors & ODEX

With our proven rock drilling techniques, piles can be installed into solid rock, or in voided ground such as heavily faulted rock, coal or other workings, and natural solution features.

In these circumstances, our flexible drilling rigs are capable of drilling vertically and at any angle, so small and medium diameter piles can be drilled to achieve exceptionally high pile capabilities. In addition, restricted access drilling rigs can be used in tight corners.

Using the ODEX system, steel casings can be used to support loose ground or fractured rock, and once the solid rock is reached a rock socket can be constructed in the rock using a down-the-hole-hammer. Sacrificial casings can be used to support the piles through any voids.

We also have the capability to advance rock sockets with our standard bored piling machines.
Rock anchors are installed to BS 8081 with full corrosion protection if required and can be used to retain rock faces or provide economic support to any retaining wall.
