The installation of new railings running along an existing brick wall would make the cutting of grass and control of weeds under and behind the railings very difficult, therefore a solution was required to stop any growth in this area.
Loose material, such as forest bark or pea shingle laid onto a weed suppressing membrane would not be ideal because when the edge of the grass was strimmed the loose material would flick out. Also the idea of using larger stones laid loose was turned down because the feeling was people could pick up and throw the stones too easily from the road side of the railings. Therefore a more permanent solution was decided upon.
We dug out a 20cm width trench under the length of the railing and removed the excess soil from site. We then filled the trench with concrete which was smoothed and made good. Large stones were then pushed into the surface to enhance the apperance rather than just have plain concrete. New grass is to be laid in the spring up to this new barrier. Because the barrier is permanent no weeds will grow through and the grass can be finished with a neat edge and easily maintained regularly up to this barrier.
This will improve the look of the grass by enabling a neat edge to the lawn and avoid any scruffy unwanted growth behind the railing while also neatly finishing off where the railing meets the ground.
