Outline of Conference Programme

As further details are confirmed they will be posted on this page so do keep checking back.

Session 1: “Best practice in basement design and construction”

Chair: Cormac Rooney, MJ Rooney Construction

Topics will include:

a)  The Royal Albert Hall: An Architects view of structural waterproofing – Kevin Kelly, Building Design Partnership
– A brief overview of the Royal Albert Hall project, discussing the list of obstacles faced, warranties and insurance backing from an architects point of view and ways to improve for the future.

b)  Failures in basement waterproofing – Marc Separovic, NHBC
– Half a decade on since NHBC launched its campaign on Basement Waterproofing, how does the house building industry look now? Hear about the NHBC’s journey so far, the key changes made and the benefits sees to date.

b) The benefit of a waterproofing specialist from a warranty perspective – Richard Smith, MD Insurance
– Covering historic issues when dealing with Basement Claims and how current requirements have reduced claims; process for developing surveyors in basement waterproofing; how Building Regulations should be applied and what needs to be developed moving forward.

c) An introduction to the liability and professional risks market and what happens when a job fails – Ian Mahony, Astute Insurance & Mark Wookey, Davies Casualty


Session 2: “Innovation/new ways of looking at waterproofing”

Chair: Emily Walker, Walker Waterproofing

Topics will include:

a) Waterproof concrete: crack width or additives – Ben Hickman, Property Care Consultants
– How do we achieve waterproof concrete basements (structurally integral, or Type B protection)? Drawing on recent projects, some of the complications of the best practice literature on crack width will be explored, together with the part waterproofing admixtures have to play.

b) Predictive maintenance in below ground structures: first year experience – Ian Davis, PPS
– After 12 moths experience of collecting live, continuous data from pump stations, the findings will be presented about the benefits of this type of monitoring, its data reduction and how to make the service more predictive, more efficient and how it can benefit the client, the industry and the service organisation.

c) Specifying sustainability in waterproofing – Richard Crossley, Newton Waterproofing Systems Ltd
– Richard considers the steps that can be taken in order to significantly reduce the negative environmental impacts caused by the installation of cavity drain waterproofing systems, as well as how such steps can be, and have been implemented in the real world.


Session 3

Chair: Mike Bromley, Chief Examiner for CSSW

Topics will include:

a) Designers view of deep underground structures – Gordon Sprouse, Fosroc
– Waterproofing of fully buried multi-level structures with a 120 year design life in a congested urban location, presents some unique challenges for the designer and contractor. The construction of completely new box structures at Nine Elms and Battersea as part of the Northern Line extension project, provides a useful insight into how these structures are constructed and waterproofed – including aspects such as the construction of the tunnel interface.

b) Stepney Green Running Tunnels, SE London – Andrew Walker, Walker Waterproofing
– Consisting of a pair of SCL tunnels 50m below ground, 17m high, 18m wide and 165m long, the Stepney Green Running Tunnels were, at construction, the largest soft ground concrete caverns in Europe. The caverns saw the launch and breakthrough of two of the Tunnel Boring Machines. With caverns of this scale and water pressures in the tunnels exceeding 6.5 bar, the project provided a significant waterproofing challenge.

c) BS8102 v BS8576 Top Trumps – John Naylor GGS
– For many years, the worlds of waterproofing and gas protection have pretty much kept to themselves.  However as awareness increases and more properties with sub structures are being constructed on gas affected ground, a clash between the respective sector British Standards becomes inevitable – so which do we use?  This presentation will focus on the main issues of gas protection for a water resistant structure and pointers for progress.

d) What lies beneath? – Rob Withers, ASUC
– Planning issues including Traffic Management plan conditions and noise
– Dealing with neighbours – why basements are considered disruptive by the public at large
– Health and Safety implications and collapses whilst basements are being constructed
– Waterproofing issues and the need to design waterproofing into the scheme at a very early stage


Panel Debate

The day will finish with an interactive Panel Debate: ‘Do you think BS8102 should be revised?’ and ‘Closing Thoughts’.
