Clay Drainer breaks down surface tension in clay soil, allowing water to drain away by gravity.
As water drains, air flows into the spaces left behind, promoting healthy plant roots and supporting beneficial soil organisms.
Decomposes into non-hazardous nutrients like nitrogen and sulphur within a few months.
The diluted mixture applied to the garden is non-toxic. So safe for use in gardens frequently used by pets and children.
While harmless to lawn grass and flowering plants, Clay Drainer may bleach moss in the lawn, potentially causing it to die.
1 litre of Clay Drainer treats over 3,000 m², equivalent to half a football pitch.
Relieves “pans” created by compacted clay soil over time, allowing for improved drainage.
Clay Drainer can also be used to re-wet baked dry clay soils during drought when the soil turns ‘hydro-phobic’; also known as ‘dry patch’.
Designed for year-round use, our products keep your lawn nourished and thriving, even in winter.
Shake the bottle thoroughly before use.
Add 10 mL of Clay Drainer per litre of tap water and mix thoroughly. Do not add any other products to the mix.
Apply evenly using a watering can with a sprinkler or a backpack sprayer. 1 litre of diluted product treats up to 30 m² - dilute with more water if your struggle to get coverage.
Apply an extra dose of water to drive the product into the soil either using a watering can or garden sprinkler.
For best results, avoid applying on very sunny and hot days. Apply once per year to maintain the effect.
I highly recommend Eutrema. I have ordered both Liquid Gypsum and Clay Drainer. Products made a noticeable improvement in our heavy clay lawn that was regularly waterlogged. I've also purchased a nitrogen fertiliser with fantastic results. Russ is always every helpful with any questions you may have.
I have used both the clay drainer and liquid gypsum this summer and found the drainage during our recent deluge in Oxfordshire was greatly improved.
Got my order a couple of months back and it's made such a difference to our garden thanks so much guys
I used this on heavy clay garden that used to flood a lot, it has certainly helped.
Put mine on two weeks ago and its definitely working.
I have used this 3 times so far this year, after having a bog all winter. Can definitely say it's making a difference.
Liquid Gypsum helps disperse compacted clay soil, improving drainage and soil structure.

What an amazing product this worked very well on my Lawn along with Liquid Gypsum. Best results I’ve ever had..
Good Value as well. Will be purchasing again!!

Used in conjunction with Liquid Gypsum, the product seems to be working and allowing the Liquid Gypsum to get down and do it’s job. The acid test more so for the LG will be in the Autumn/Winter but so far so good.

After researching fairly extensively about my heavy clay based (new build) garden I opted to purchase the Clay Drainer as well as the Liquid Gypsum. I can honestly say it’s worked a treat so far. When my (new build) lawn was laid some two years ago it looked great but over time weeds started to grow all over and the lawn became saturated when it rained! Now, after using this in April 2025 along with Liquid Gypsum (aerating and lawn seeding) my lawn looks like a lawn again! Water doesn’t pool anymore when it rains. I’ll be using this again in Autumn to further improve the soil structure and drainage.

Hi Andrew. We recommend applying once a year to maintain an effect. Thanks. Russ
