    Everything you always wanted to know about soakaway testing and groundwater monitoring*

    Everything you always wanted to know about soakaway testing and groundwater monitoring* (*but were afraid to ask).This was the title of a recent lunchtime CPD presentation that Simon and Callum recently gave to a company of drainage and civil engineers. Whilst the pun in the title, taken from a Woody Allen film, might have been lost on many of the audience, its content certainly wasn’t. I am all for sharing what we know, particularly if it takes less than an hour, over lunch, and especially if it helps make all of our lives easier and to the benefit of others. Whilst standing up in front of a room and talking for around 40 minutes isn’t my idea of fun, the benefits are great and many, so we are happy to provide a similar talk to others, if anyone fancies it.    Providing a pizza lunch is optional, but always helps with our availability!

    UKAS Accredited Testing for Residential Development in Somerset

    Extensive geotechnical and contamination laboratory testing was recently undertaken as part of a ground investigation for proposed residential development site on the outskirts of Weston-super-Mare. In addition to classification (plastic and liquid limits and particle size distribution) tests, quick undrained triaxial and oedometer consolidation tests were carried out to provide information for foundation design. pH and soluble sulphate testing (BRE SD1 suite) was also undertaken to confirm the buried concrete class requirements. A broad range of contamination testing, including asbestos, heavy metals, polyaromatic hydrocarbons (PAH) and total petroleum hydrocarbons (TPH), was undertaken to provide information for human health and controlled waters risk assessments. The testing was UKAS accredited and Ruddlesden geotechnical’s close working relationships with both the laboratories helped ensure the testing results were issued promptly.

    Rope Access Work for Cliff Stability Survey, Dorset

    Ruddlesden geotechnical were commissioned to undertake a cliff stability survey for a property situated on the Isle of Portland. In order for kinematic analyses to be undertaken, to inform the need for remedial (stabilisation) measures, rock mass data was required. Due to the inaccessibility of the limestone escarpment, rope access was required to obtain the necessary data. Ruddlesden geotechnical obtained the data under the supervision of IRATA-qualified personnel, who managed all of the health and safety aspects of the project.
