Invasive weeds and plants, such as Bamboo, Japanese Knotweed, Himalayan Balsam, and Giant Hogweed can cause serious damage if left uncontrolled which is why invasive weed control is vital. Bamboo and Japanese Knotweed are particularly difficult to manage as a result of their fast-growing and aggressive rhizome root systems. These species are notoriously resistant to physical removal because even a small fragment of rhizome root will regrow and develop a new and invasive plant.
THE DAMAGE JAPANESE KNOTWEED AND BAMBOO CAN CAUSE
Rapid growth, combined with the strength that these invasive weeds accumulate through maturity, means that these species can break their way through many apparently robust manmade construction materials, such as concrete, brick, and asphalt. Japanese Knotweed’s rapidly spreading interconnected rhizome roots systems facilitate their search for a breakthrough point across a relatively wide area where they then thrive via access to nutrients, water, and sunlight. The surface breakthrough can be problematic as the location of the main host plant may not be obvious. There are recorded cases of Japanese Knotweed finding its way into residential dwellings through cavity walls etc, which clearly has significant practical and economic implications for treatment, particularly when the source is difficult to identify and eradicate.
Japanese Knotweed effects up to 1.45 million homes throughout the UK, which amounts to around 5% of residential properties. Homeowners that have this invasive plant on their premises are likely to find their property value blighted. Furthermore any landowners who are deemed to have allowed these species to encroach on to neighbouring properties are likely to find themselves legally liable for the consequences. It is therefore clearly very important to implement invasive weed control as soon as possible and to maintain that invasive weed management system.
INVASIVE WEED CONTROL – THE BARRIER SOLUTION
Invasive weed barrier installed vertically one meter below the ground surface.
Flourishing shoots and leaves
Roots under control, and only grow to a permitted space
Ground left uncontaminated from Bamboo or Japanese Knotweed rhizomes.
CONTAMINATED SOIL LINERS SOLUTION
If the invasive plant area has become too big of a problem, removing the contaminated soil after the plant has died from winter weather may be the only option. TCS offers contaminated soil liners and covers, which enable you to transport the affected soil to another location and isolate it. The liners and covers seal off the contaminated soil to prevent any roots or rhizomes from reanimating by cutting off their nutrients and sunlight. The liners can also be utilised as a burial pit to be sealed off from public view. A hi-visible orange woven or non-woven may also be used within such an application as a warning layer for any future construction to identify that there is contaminated soil wrapped up and buried.
TCS offer 32m x 300m long lengths of Powerscrim HDPE liners.
