SP9012 : Lining the canal sides on the Wendover Arm

Lining the canal sides on the Wendover Arm
Lining the canal sides on the Wendover Arm
The process involves the following stages
(1) The side is excavated smoothly down, using the JCB
(2) Large sheets of a waterproofing fabric containing a bentonite filling are added.
(3) A wall of concrete blocks is laid against the sheeting to protect it from damage from the barges once the canal is in use.
(4) The top of the wall is covered with a roll of coconut matting
(5) The upper part of the sheeting will later be covered with soil.
(6) When the sides have been completed along a reasonable length the bottom will be covered with a large sheet of matting.
(7) The matting on the floor will then be covered with a thick layer of soil.
(8) When a suitable length has been prepared a temporary earth dam will be added and the area flooded.
(9) When eventually the restoration work connects with the canal at Tringford the earth dams will be removed and canal badges will again be able to go along the canal.
At the present rate this is unlikely to be before about 2025.

Wendover Arm, Grand Union Canal
The Wendover Arm was planned as a feeder to supply water to the Tring Summit of the Grand Junction Canal (now the Grand Union Canal). It was completed as a navigable canal in 1797 and operated as such throughout the 19th century. However the canal leaked water and was closed early in the 20th century, and the water was piped into the reservoirs at Tring. As a result the route of the canal currently splits into three sections:
From Wendover to Drayton Beauchamp (via Halton and Buckland Wharf) the old canal channel carries what is, in environmental terms, a very healthy chalk stream. Because of the minimal human disturbance it supports a wide range of animal and plant species.
Between Drayton Beauchamp and Little Tring the canal channel is currently being relined so that it can be re-watered allowing canal boats to travel to Buckland Wharf, where low road bridges currently prevent further progress. This work is being carried out by the Wendover Arm Trust LinkExternal link
Between Little Tring and the Tring Summit of the Grand Union Canal the canal is fully navigable, and a short section has recently been reopened to provide a winding hole. This section gives great pleasure to those who travel in barges but is environmentally far less interesting than the Wendover end because passing barges stir up the mud.
