Dowels

Unlike soil nails and rock bolts which act in tension, dowels act purely in shear. Dowels are not stressed and are passive until there is movement in the base material. Dowels are also used extensively to ensure structures are fixed securely to the base material.
Condor Projects have completed a number of successful projects
ranging from fixing down spillways at the base of dams and reservoirs to pining down flood overflow tanks to prevent ground water causing the tanks to 'float'.
Condor Projects have a range of specialized and custom built equipment for access on difficult sites, especially where scaffolding or benching may be impractical or too expensive.
Condor Projects have installed the full range of dowels, from mild steel for cheapness in a temporary situation to GRP and stainless steel bar to increase longevity.

Middle Image - A high watertable required the fixings to be placed using water resistant resins. All fixings were tested to BS8081 by an independent testing body, arranged by Condor Projects.

Bottom Image - Drilling to hold down a spillway. Dowels were fixed up to 5 m deep into the base rock to prevent the concrete spillway lifting during flood conditions.

"We have been extremely impressed with Condor Projects' pile cutter. The machine has delivered all that Condor Projects said it would do, and more. We've seen safe cutting to excellent accuracy and reducing time on the job by fantastic margins. We're sure to use it again."
