Miércoles 25th Abril 2018 @ 09:00 – 13:30

Universidad Politécnica de Valencia

Conference organised and promted by (Organiza y promueve):

Supported by (Colabora):


Learn how to control groundwater inside and outside earth retaining structures to ensure a safe & stable working environment. Discover the theory behind the mechanism of groundwater control, together with gaining an understanding of the practical techniques used in industry. 


A series of case studies will be used to illustrate effective Groundwater Control and Pore-water Pressure Relief techniques, within and surrounding earth retaining structures, including: jacked and underpinned shafts, concrete secant and contiguous pile walls, diaphragm walls, steel sheet piled and combi walls, king post walls, earth embankments, soil nailed walls and reinforced anchor walls.


In addition, OGI will present the groundwater control system constructed for the widening of the Seaforth Passage, a project for which OGI was awarded “Highly Commended” in the 2016 British Construction Industry Awards and in the 2017 Ground Engineering Awards. This seminar will provide a unique insight into the challenges encountered during the design and implementation of the groundwater control system.
