WJ at Chalk 2018
We're delighted to be exhibiting sponsors of Chalk 2018
Chalk 2018
The British Geotechnical Association (BGA) with support from the Engineering Group of the Geological Society (EGGS) will be hosting a major two-day international conference on Engineering in Chalk on 17th and 18th September 2018 at Imperial College in London.
The last major conference on Chalk was held almost 30 years ago in 1989 in Brighton. Since that time, considerable work has been undertaken internationally through research and in many major projects in Chalk, advancing our understanding of its origin, nature and engineering behavior.

It is big, and it is clever
Meet our new rig
Probably the most technically advanced mid-sized water well drilling rig operating in the UK today, our new Conrad Combi 500 is a state of the art
machine. It’s powerful and effi cient modern engine is compliant with the highest emissions standards, making it one of the cleanest rigs in the business.
It’s smart, too. Intelligent power management automatically reduces engine rpm to stationary when no function is operated for 5 seconds. Equipped with remote controlled hydraulic functions, designed to eliminate manual handling, also provides a safe working environment.
The reduced noise and exhaust emissions, coupled with the ability to operate in an incredibly small footprint, make WJ and our Conrad rig the ideal solution for installing wells up to 500mm diameter and up to 200m depth in restricted urban sites.
Featured Chalk Projects
We have successfully delivered a number of key projects where chalk formations have been a primary factor
Crossrail Station, Canary Wharf
Canary Wharf will be one of the largest Crossrail stations. Read more to discover how we installed 11 chalk wells, drilled to a depth of 90m….
Brighton i360
In order to make the Brighton i360 a reality, WJ needed to achieve the drawdown of tidally variable groundwater levels from underlying chalk….
University College London
WJ were called in as the principal contractor and entrusted with the execution of the drilling of a single chalk borehole to a depth of 110m with a finished diameter of 300mm….
