Hi
Naylor Land Drainage Pipe Perforated Coil
as far as I can see this is sort of a soakaway, so in a moss infested garden could I put this in a trench to try to divert water away ?
Aye - would depend on the garden really. Is it on a fall? ie higher at one end then the other, or mainly flat?
If it's mainly flat then would need to install a snake like loop of the landrain throughout the garden to catch a lot of rainfall.
Always amazed me how effective this stuff is when installed properly.
you don't need to be that deep - enough to acheive a fall from one end of the landdrain to the other. lay the drain in the bottom of the trench and surround with a 10mm clean stone to approx 75 - 100mm shy of the surface. top of with a free draining grit sand ( river sand ) then finish with a sod of turf to level. Everything needs to be free draining otherwise water won't reach the pipe. The end of the drain needs to be connected to your surface water drainage via a silt trap.
alternatively strip all your existing turf - aerate the subsoil with a fork then replace the turf with an amenity type sod from Rowlawn (or similar). instant good lawn
Hi thanks, garden is on a slope but towards house, however the house has a patio with a drain at the far edge (ie nearest the hill)
diagram - which may work - below
next House up hill
-----------------------Garden Wall (4ft)
-------------------------------------------my Garden
-------------------------------------------------------wall (4ft)
---------------------------------------------------------------patio then my house
------------------------------------------------------------------drain at wall end
so I can slope pipe down to patio next to patio drain, patio slopes away from house
My garden is sort of a square, so I was planning to lay a trench around edge of graden with both ends leading to the patio where the drain is
So trench appears to need to be 12" deep (pipe is 4"), so dig trench, shingle layer, pipe, shingle layer, then recover with tosoil
I laid some pipe in my dads garden once... 🙄
In all seriousness, his garden is on a fall anyway so we relevelled it all. Put on drainage in Y formats in trenches. Need some decent gravel an sift out all the fines. Labour intensive but my old man can walk on the lawn in winter now
