More drainage news....

As the day finishes on the second week of the greens drainage works I'd like to give you an update on our progress.
To quickly recap, the plan is to drain 5 greens & approaches this winter working alongside the contractors we have engaged & worked with before, ProFusion. The greens that are being drained, 5th, 7th, 10th, 15th & 17th will have drains installed every 3 metres with the drains installed at 45 degrees to intercept the water moving across the natural fall of the green surface.
Adding this primary drainage system to the greens is the first step in moving to ensure we have better quality putting surfaces all year long.

So the process involves the drains being marked out by lasers to ensure we have the correct falls and angles. The turf is then cut and lifted and stored to be relaid once the drains have been installed.
Next the drains are cut with a trencher using laser guided technology to ensure the correct levels are maintained, each lateral drain is cut too at least 550mm falling into a main outlet drain which is set deeper than the lateral drains






Once the trenches have been dug pipe & stone is then added, we're using an 80mm diameter pipe that will then connect into the outlet pipe. The gravel layer comes to within 300mm of the surface we're the rootzone layer is then added. This rootzone layer is compacted to reduce the potential for the drain lines to drop once there put in. This year we have altered some of the machines we use to make the process quicker & so we get a better finish.












Once the rootzone layers are back to a level the turf is then relayed and a light rolling program is started to help the turf knit back together.

So far we've made good progress with the first three greens being drained and returfed within the first two weeks. Work has now moved on to the 15th green & finally we will move on to the 17th.

I'll post again soon with further updates.
