When clay soils become compacted, they form a dense layer or “cap.” These clay caps hinder rainwater from draining properly, leading to waterlogged conditions, especially during heavy rainfall.
Ideal for areas where traditional ploughing or manual digging is impractical, such as gardens or smaller plots.
When applied, the large calcium ions in Liquid Gypsum attract clay particles, forming aggregates known as “flocs.” These flocs enhance:
Liquid Gypsum was developed by Dr. Russell Sharp in 2016 and remains formulated in-house to Eutrema’s high standards.
Liquid Gypsum is particularly effective for:

I'm extremely pleased to report that following the application of your liquid gypsum product our new build quagmire, sorry I mean lawn, this has resolved our waterlogging with the lawn remaining firm and draining rainwater.
Did my garden 2 months ago its not coping with all this rain at the moment will have to wait and see how quickly it drains when the rain stops, currently flooded
- Update it stopped raining overnight and wow the flooding has gone would normally have taken weeks to drain away so very impressed used both products all of it over a few weeks will do it again next year.
My Dad is thrilled with the rapid results after trying everything else to fix his poor quality 'new build house' lawn. He now has a green lawn that isn't waterlogged and his neighbours are impressed too.
I bought some of this to mitigate my heavily saturated clay lawn in my new build house. I have to say I'm very impressed with the results and there has been no waterlogging despite some of the weather we've had.
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 bought the Liquid Gypsum and i have been surprised at how quickly it does work. My garden has about a metre depth of clay and when it rained my lawn looked like a 3d map of the Lake District. Drainage was pretty much non existent, now however there are only a few areas where the water is slow to drain. I'm going to keep treating until it drains better. I'd recommend this product.
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 applied the liquid gypsum about 5 weeks ago, I've noticed that I don't get anywhere near as much rain running off my lawn and pooling against my house which has got much better as the weeks have gone on.
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.

Helped improve the drainage on the lawn. Our soil is very heavy clay and so drainage is poor in winter after torrential rain.
Grass seemed to be a luscious green in the weeks after application too (compared to the small bit we left untreated)!
