Working on the River Lea in East London our client is undertaking UXO works as part of a flood alleviation project.  The site is one of London’s oldest surviving industrial centres and weight restrictions are in place at the point of launch.  Our investigation pontoon solution was equipped with load spreading mats and counter balance IBCs to maintain stability.  The construction of the pontoon provided 40mm bore hole access 2m from the bank with a capacity to test 20m lengths in each position.
