Solving waterlogging problems with solutions that work.
Have you got a Soggy waterlogged lawn or garden that holds water and is muddy ?
When what you really want is a lawn the kids can play on after school, without bringing saturated mud into the house. Or maybe flower borders or a vegetable garden, with soil that isn't boggy after rain.
It's a common problem, not just for homes and gardens built on low lying land, a floodplain, clay or compacted soil.
Structures you or your neighbour have added, like retaining walls, footings for house extensions and patios can all divert surface rain water and underground springs causing waterlogging.
You can spend a lot of time and money trying to trace the source of the problem, leading to disputes with neighbours, surveyors, the builder who built the extension the landscaper who installed your patio and retaining wall without considering the effect on garden drainage.The only solution that works is to drain the water from your lawn.
Whether your garden or lawn slopes or is level we have a drainage service or DIY solution to dry it out.

Herringbone French drainage system.
Our garden drainage services and cost.
This is the drainage system we recommend and install under lawns
This is the garden drainage system we recommend and install on clay.
Based on French drains, its installed under the existing turf or garden topsoil and solves waterlogged garden drainage problems, its easily the best drainage system for clay gardens. The drainage system takes about four days to install and the garden starts to drain immediately. Why put up with a lawn the kids can't play on and mud you can't plant in. The problem won't just go away.
Herringbone French drainage system.
If lawns are waterlogged over the whole area, a French drain laid in a Herringbone pattern is your best bet.
This is how we do it
Mark out and dig the main trench from the highest part of the lawn, to the lowest.
Connect to a Soak away, Sump, or Surface water drain.
Then mark and dig out the side trenches to connect to the main drain, forming a herringbone pattern.
The side drains join the main drain at a 45 degree angle and are spaced at 10 ft intervals for clay soil and 25 ft intervals for loamy soil.
Fill the drains with wrapped gravel. I/e line the trench with A heavy duty landscape fabric, for sale in the drainage shop, to keep earth out of the gravel and allow water to percolate freely through the gravel, then shovel coarse gravel onto the landscape fabric and wrap the fabric over the top of the gravel.
Next loosely shovel 3 or 4 inches of topsoil back into the trenches, slightly overfilling to allow for settling and making sure not to compact the soil.
A gravel drain trench system installed below the surface, solves most garden drainage problems. Ever since the Romans used them to solve drainage problems, not much has changed, perforated plastic pipes (holes at the top or bottom, depends who you ask !) came and went, French drains still work.Why are they are called French drains? Although stone drains go back the Ark, they are actually named after an American, Henry French a 19th-century judge,gardener and farmer
Draining the water away.
Soakaway or Sump or Drain.
At the lowest end of the main trench dig out a soakaway at least 4 ft deep filled with chunky gravel or clean rubble and link the main drain to the the soak away.
Soakaways are unlikely to work in clay soil.
If after you have dug out the soakaway, you find the water is not draining away, you will need to look at either connecting into the surface water drain system or where this isn't feasible, converting the soakaway into asump and pump
After installing the drainage channels, aerate and returfover grit sand.
If not allready compacted, the garden surface will have been flattened, during the drainage work.
Ask your drainage contractor to spread grit sand over the whole area to be turfed including the French drain trenches and aerate the surface, this ensures the drains work to full capacity by draining surface water into the soil and drainage channels.
If you are not laying new turf over the completed drainage system, spread grit sand over the whole lawn. Leave the tips of the grass showing and aerate. Hard work but you will end up with a level well drained lawn that's nice to walk on.
See the lawn care tips on the landscape gardeners page. I also offer a lawn turfing service in all areas of Southern England, where we have installed land drainage systems.
Aerating the whole area, including the trenches, ensures surface water drains from the surface into the soil and drainage system. How to aerate here.
Do not connect into the Foul drainage system: this is the drainage system that removes the waste from the toilet, bath, sinks, washing machines, dishwashers and showers and you will need permission from the local council.
You can connect into the surface water drainage: this is the drainage system that deals with rainfall from your gutters etc.
In gardens that slope away from the house it may not be possible to connect the gravel drains directly into the surface water drainage system and the rain water may need to be drained into a sump and pumped. I have included some basic information on thedrainage sump and pumpspage. also some other drainage systems you may want to consider.

What does installing a Garden drainage system cost.
The average cost of French drain installation in the uk is £2500.
The main factors effecting the price of installing garden drainage are:
Access to the garden, can we get a digger in to dig out the trenches and soakaway or will the trenches need to be dug out by hand.
Levels, does the garden naturally slope toward a rainwater drainage system.
Dispersal of the water, will a sump and pump system be needed.
Disposal of excavated soil and Clay, can it be used in the garden or will a skip be needed.
Drainage gravel, can it be delivered directly into the garden or wheel barreled in.
Home visits to advise and prepare a quote cost £200 (refundable)

Just completed the drainage on my lawn using your diy guide, must say it was simple to follow but still hard work, but what a difference, my boys can play on the lawn again, and I did save a lot of money. I found the gravel calculater really useful, ended up with a bit left over but probably my calculation.
Thanks again (well worth a tenner)

I just wanted to get in touch to let you know that despite the dire weather we've had since you installed drainage for us back in April, it has been working fantastically. We are so pleased - it has worked even better than we hoped it would. We no longer have to wear wellies and run the risk of sinking in a bog every time we venture outside! With any luck we may even get some summer soon and be able to actually sit out there!The other thing is we found a steel flask in the garden that one of you left - I washed it out and put it to one side to post but forgot - have just rediscovered it! Do you want me to post it back to you, or are you back in Cardiff anytime to pop in and collect it? Let me know what's best.Thanks once again. We will gladly recommend you to anyone needing drainage work done in future.
