Building Engineer: beware of Japanese knotweed on construction sites

Building Engineer: beware of Japanese knotweed on construction sites

Japanese knotweed on a construction site

Environet are featured in the latest issue of Building Engineer, published in April 2017.

Environmental scientist and Managing Director Nic Seal speaks to Building Engineer and explains how best to tackle Japanese knotweed on construction sites, highlighting the importance to checking out all knotweed liabilities before purchase.

Environet were commissioned to survey a residential development plot, which had been undergoing herbicide treatment for over 7 years. When conducting trial pits, live rhizome was found. Cost estimates of between £250,000 for Xtract™ and £500,000 for “dig & dump” made the site uneconomic to develop.

Following a degree in Environmental Science from the University of London and a few years spent working in engineering, I started Environet in 1996. Since then it has grown to become one of the major players in the field of invasive plants, including Japanese knotweed and bamboo. Recognised as one of the UK's leading experts in the field, I have secured patents for many innovations relating to the treatment of Japanese knotweed.

“We had a large stand of bamboo removed, thinned, contained and replaced. The customer service has been first class. Joe and Jason were fabulous and kept me well informed at all times”.
