Liner Services: Farm Lagoons
AD Plant Digestate Lagoons
Expert lining Services across the UK.
There is a growing need to manage our waste. All the food waste we produce here in the UK goes to a network of anaerobic digestion (AD) plants across the UK. These plants turn this waste (organic matter) into biogas – a highly renewable fuel. It can be used to power just about anything – from vehicles to the national grid.

When the gas has been harvested, the waste material is pumped from the AD plant to settling ponds for further processing before the material is returned to the land as a nutrient-rich, organic fertiliser.
110% reliable & repairable
Our membranes are exactly that. Ultra reliable and virtually bullet-proof.
Lasting up to 60 years, EPDM membranes don’t break, nor do they degrade in the sun. EPDM is designed to sit dry (or wet) in the background for that event for which we all hope will never happen.
Should your liner become damaged – either through accidental or wildlife strike/damage, EPDM can be fully repaired. Whether it’s a puncture or tear, the repair can be warranted too, if undertaken by a qualified engineer.
Using EPDM repair processes and products, we can quickly restore the liner to a fully sealed system to maintain your water storage integrity.


Why EPDM?
There are a variety of materials available to the UK market for lining – plastic, LLDPE, HDPE, Bentonite, Butyl & EPDM. Plastic liners (plastic, LLDPE & HDPE) have a life of up to half (28 years) that of EPDM, whilst butyl will last 25 years +/- 5 years. Whilst EPDM is more expensive, it only needs installing once and should last well beyond 56 years of life. You ultimately save by not needing to re-engineer the site half-way through an EPDM liners’ life.
With Elevate GeoGard EPDM membrane’s working life of up to 60 years, it is:
- Fully UV stable
- Repairable should you damage it and
- will outlast the best HDPE liner by doubling its life.
A great investment where ownership of the project, for example farms, pass down through the generations.
With over 15 years in the industry, and seeing more the effects of cheaper membranes breaking down over time, which can cause micro plastics (POP’s) to enter water-courses. Turtle have chosen to only install EPDM rubber membranes. They are a natural product, entirely UV stable, have double the life span of plastic membranes and negate the risk of these pollution’s.

We only use the best materials
Life of service
Visit this life project - now 51 years old
Wilst EPDM is expensive, it only needs installing once.
Laboratory tested to 56 years of life, we believe the claim of double-the-life of other membranes is vald –
You should expect up to 60 years of service.
Weigh up the costs of a half-price liner, but doing the job twice – or more?
Short term savings normally cost more in the long run…
Microplastics
The Environment Agency are becoming increasingly concerned at the levels of POPs being displayed in the environment, especially our water-courses.
EPDM rubber liners are a natural product, entirely UV stable and have double the life span of cheaper membranes.
Recent public concern of river pollution along with climate change has seen awareness and choice of membrane arising during the planning process.
Turtle Productions fully endorses and supports EPDM membranes.
Zero waste efficiency
Cost efficiency is not only key, but critical too in these modern times of price rises and emphasis on planetary resources.
EPDM membranes are the most expensive on the market now, so waste is simply not an option. Therefore every quote, every site visit, every installation is meticulously worked out at the design stage to use the absolute minimum quantity of membrane in a variety of stock widths to ensure there is as little, to no waste as possible.
We pride ourselves that in 14 years joining liner on site, we’ve never ordered a skip! That’s less of your money wasted.
Quotation, not estimate
We DO NOT quote on a square metre basis, with estimates that are subject to a site visit, inflation or bid-low to create a false impression to engage your work. Your drawings are accurate, so you should expect your lining contractor to be able to interpret these and give you the most valued service possible.
This is Turtle Productions approach. Our quote is a fixed price quotation, not an estimate, based on known dimensions which allow us to line your project correctly, on time, in budget, without wastage and can leave you reassured that the lagoon will withstand the future test of time.
We have an extensive Portfolio of projects which is not only testament to the service we offer, but something we are proud to be associated with. Below are a few examples of our work, why not go and explore?
AD plant digestate pond in Herefordshire
We were asked by our friends at AMS of Hereford to assist them by lining this digestate lagoon for a client of theirs in Herefordshire. Their AD (anaerobic digester) plant processes food and animal waste producing biogas and liquid. Further processing of …
Our commercial projects portfolio
Our extensive online Portfolio features dozens of projects from concept to completion too. Please visit our galleries, click through the image on the project and then see not only how the project was constructed, but also many re-visits we’ve undertaken.
Whilst it’s your project, we still consider it our baby and we’re always there to support you in the future when you need us.
