Symptoms of Poor Garden Drainage
- Grassed areas take a long time to drain and dry out after heavy rainfall
- Children and pets are unable to play outside without trailing dirt and mud back indoors
- Water present even in summer and in extreme cases rashes on the lawn
- Existing drains have become blocked
Factors Contributing to Poor Drainage
- Soil type particularly heavy clay
- Lie of the land
- Sunshine or shade
- Changes to neighbouring areas
The Solution
- The installation of a herringbone drainage system with gravel place below the surface of your lawn.
- Replacing the existing faulty system.
- In some cases, totally replacing soil type utilising sand, gravel and top soil.
-
Where there is no obvious outlet for water, a sump can be installed with electric pump to remove water to nearby drain or ditch.
Other Services
- We also install all-weather play areas which include removal of topsoil, draining the designated site, laying of Terram sheeting, and replacing it with playgrade woodchip from Firewood Express
- Re-turfing – which can be in combination with or separate from our garden drainage service.

Drainage Solution
In some instances, a natural “run-off” can be achieved without the use of a sump system. Ground levels can be taken to establish the natural run of water and new drains can be installed to remedy the flooding.
Drainage Solution
“Bad flooding caused by low lying gardens, with no obvious outlet for water, can have a sump installed which pumps the excess water to a nearby drain or ditch.”

“We hired THM Garden Drainage to sort the poor drainage in our back garden cause by compacted heavy clay soil. Ewan and his team did a great job and we’re very professional. They took the time to answer any questions we had at every step. Thanks to Ewan we can finally use our garden.” – Scott Haldane

Testimonials
“For many years we had a serious drainage problem with water running down our driveway and also causing the garden to be waterlogged. Every winter the driveway would ice over resulting in having to spread rock salt over the ice in order to prevent anyone from slipping.
Any company previously contacted would not assist or advise a way forward for us.
Then we found THM Garden Drainage. Having arranged a suitable time to visit, Ewan then explained in detail how he would be able to solve our problem. The work that Ewan and team carried out on this very long monoblock driveway included installing an electric pump and additional drainage in the garden.
It was obvious that this work was very challenging but Ewan and team never gave up until the problem was fully addressed and completed.
We were very fortunate to find THM Garden Drainage and for the first time in years we won’t dread the winter. No more having to de-ice the driveway.
Many thanks THM Garden Drainage”

“Ewan impressed us from the start with his knowledge about drainage. He took time to work out the most suitable method, and explained each stage carefully. He has successfully solved a difficult and long – standing problem in our garden. He and his team worked in a professional and friendly manner, and we consider ourselves lucky to have chosen the correct man for the job.
Thanks, Ewan to you and your team for your excellent work!”
I am very happy with the service from THM Drainage, from first site visit until job completion and would highly recommend them. Like most new build properties, our back garden suffered with very poor drainage and clay soil. Our lawn was a swamp for most of the year. Ewan spent time on the first site visit and gave us a considered and detailed solution. The quote was very reasonable for the expertise and amount of work needing done. Job was completed to a high standard and they left the property tidy. Communication was very good, job was done when agreed and my questions were always answered. The drainage has now improved greatly and we are happy with our service. Thank you Ewan and his team at THM Drainage”
It’s been a bad week for weather but the drainage you installed has made a difference. The earth is drying out quickly even after all the rain we’ve had this week.
You were so efficient and professional and I have never known such clean workers. I would recommend you to anyone needing this work done. It’s five stars from me. Many thanks.
“I had a serious issue with flooding in my garden, and Ewan resolved it quickly and effectively. His expertise and experience were clear from the start, and he knew exactly what needed to be done. I’m grateful for his professional approach and recommend his services for anyone experiencing significant drainage problems”
We arranged for THM Drainage to fix our drainage issue that we had in the back garden.The pipes turned out to be extremely deep, however this was not an issue as Ewan and his team spared no effort to solve the problem. The whole job only took 2 days from start to finish and he kept us informed at all times.
I would highly recommend THM Drainage to anyone with drainage issues.
5 Stars
We had drainage installed at our property in Jackton and couldn’t be happier with the service from THM. I chose them because of their excellent online reviews and the fact they’re a local company, and I’m glad I did.
Ewan and his team were brilliant to deal with – the whole process was straightforward, well-organised, and the work was completed to a really high standard. The aftercare and follow-up have also been excellent.
Highly recommend!
“Ewan provided an excellent service from start to finish. This included visiting the garden to determine a practical passive drainage solution, providing a reasonable quote, and undertaking the works within the agreed timeframe.Before, our garden was waterlogged during dry spells. Now, even following prolonged heavy rainfall, there are no issues with waterlogging.
Ewan and his team were friendly and professional at all times, and a pleasure to deal with.
Thanks again Ewan and the team!
We hired THM Garden Drainage to sort the poor drainage in our back garden caused by compacted heavy clay soil. Ewan and his team did a great job and we’re very professional. They took the time to answer any questions we had at every step.
Thanks to Ewan we can finally use our garden.
A very big thanks to Ewan and the team at THM Garden Drainage, quite simply the drainage installed in our garden has completely transformed it, we had years of the lawn and borders flooding after heavy rainfall, which destroyed plants and shrubs and made the garden totally unusable. Now even if we have weeks of rain our lawn and borders look great.
This is the best investment we have made in our garden.
I highly recommend Ewan a great worker and tidy too. Thanks again
“Ewan has taken care of my drainage and landscaping needs on Crawfordston Farm since 2010. He is an extremely experienced individual delivering a high quality service and first class advice. He is a top class professional in his field.”
Big thank you to Ewan and his team for a very professional job on our garden drainage issue.
The ground is already showing positive signs of less water retention following the drainage installation, which was achieved with no disruption to the rest of the garden.
On completion they tidied up to a very high standard.
We recommend you to others who have a similar issue as to what we had – 10 out of 10.
Well done and “Thank you”
Ewan recently installed drainage in our garden. We were very impressed with his workmanship and professionalism throughout the entire process. From the initial consultation to the final touches, Ewan was attentive to our needs and communicated effectively with us every step of the way.
The drains that Ewan installed have completely transformed our garden, and we no longer have to worry about standing water or flooding after heavy rainfall.
Overall, we are extremely pleased with the work that Ewan has done, and we would highly recommend him to anyone looking for a skilled and reliable contractor for their garden drainage and landscaping needs.
Thanks again to Ewan and THM Garden Drainage for a job well done!
“We have used Ewan from THM Garden drainage on a number of occasions and have found his work to be of an exceptionally high standard. His attention to detail and knowledge is first class, particularly for garden drainage work. I would have no hesitation in recommending Ewan. And he leaves the garden tidy!!!”
“Over the last 20 plus years, on an almost yearly basis, I have entrusted my drainage maintenance and renewal work to THM Drainage .
I have no hesitation in recommending Ewan for all drainage work. When you hire Ewan not only do you get brawn you get Brains as well.”
“Ewan from THM Garden drainage has done quite a lot of work for us over the last few years. From big field drains to smaller drive drains. All work carried out carefully and always a clear explanation of what the work entails. Ewan is always enthusiastic and prompt and the work gets done.”
Went to Ewan from great reviews online. We had a damp smell from water draining down our garden and under our house. Ewan asked for photos and advised us to heat the house because it had been empty and advised us to wait and see if the smell dissipated and did not rush to take our money!
Then we had a downpour and water was evident. Ewan gave us an estimate that was lower than another contractor. When he came to survey he realised we had limited access to the back garden and couldn’t get machinery in so we would need to do it by manual labour. We expected to pay more but he said the garden was smaller than my initial measurements so the estimate remained the same. He did a professional job. No more water and we are very happy.
Would definitely recommend him.
“Thanks again for a great job. I’ll recommend you to anyone with similar problems.”
