<p>Price from London drainage</p>

<p>As discussed we have various machinery to remove root ingress from the inside of pipework and manhole chambers, this can be completed by way of an electro-mechanical Picote machine with oscillating chains to remove the roots or by use of a high pressure water jetting machine with a &lsquo;Warthog&rsquo; nozzle.</p>

<p>The team will attend and set up the required equipment and begin to remove the root ingress, this will be monitored with a CCTV camera that we will have on site with us, to allow for as much root to be removed as possible (The extent of the root removed will be dependent on the configuration of the pipework, however, we can usually remove 90% plus.)</p>

<p>On completion of the root cutting the CCTV unit will be used to determine distances and provide evidence of the defective areas, a report will be sent with recommendations for repair, if the roots are cut out and no further works are completed then the root ingress is likely to return when the weather becomes dryer and the water table lowers due to lack of rainfall. When this period arrives the cut back root ends begin to regrow to extract water from the drainage and continue to grow until the pipeline is again blocked.</p>

<p>Over time this growth will inevitably damage and break the pipe, hence the need to install liners and/or patches over the ingress points to seal and stop the root growth.</p>

<p>The cost to attend with heavy manhole lifters, a CCTV inspection unit, high pressure water jetting capabilities and the Picote machine will be &pound;675.00 plus vat.</p>
