Water logged lawn / poor drainage

While it is relatively dry I want to sort out my garden drainage. I have a raised lawn, south facing but it never seems to dry out. People have
mentioned french drains and sand but not sure of the best course of action. Any help would be great. Thank you

"I would suggest removing moss and aerating the lawn before you dig it up to put in drainage.
Moss and thatch reduce the amount of water that can move through the soil into the ground, so by removing the moss and aerating the ground you should get the water table to drop.
I hope this helps."

"Yes I would look at installing a good draining system or a soak away to prevent it getting worse"

"Dig a trench, make a soak away with pea gravel or add a land drain to soak it away"

First you should understand why your garden never drys out. Is it because of a deep waterproof layer? Or because it collects water from other sources like an underground spring? May it be because of concrete base of a patio/shed or the footing of a wall?

Second you need decide where to send the water you will collect with the drainage system: in another property or in manhole/gutter? Remember that the water runs from high to low and on this will depend how much you have to dig.

When these details have been decided you need to drawn your drainage system like a grid or more likely like a fish bone. This to know where to dig the trenches and how long they'll need to be and calculate how much material you need (meters of land drain and sock to protect it, gravel to cover it.

Depth of the excavations depend on the type of soil, how deep you want to dry it, the lowest point of your system (i.e. the place where the water needs to go into).
Hope this is clear."

There are plenty of ways to get rid of surplus or surface water. I would never advise on a certain type of drainage without having seen the site or carried out a investigation through a small excavation. This is due to needing to know the ground conditions at least 600mm to 800m depth to see if some drainage methods could work. Aco or France drainage would work if you had a drainage mains to the property close by or room and ground conditions for a soakaway.

I hope this helps."

"Usually with this sort of situation there is a blockage, it tends to be builders rubble used as drainage, which doesn't work.
I use either a flint gravel or plastic drain crates I the ground to take the water.
Hope this is of some help."
