Ecofill FAQ and Client Comfort

The ecofill solution works with a combination of brand new, custom designed and patent pending plant machinery that mixes clays and subsoils (ex-situ) with a bespoke, formulated proprietary binder at a predefined ratio. When the end product is compacted the stiffness and load bearing of the ground dramatically increases in order to support the trafficking and loading that will be placed upon it. Traditional binders, such as Quicklime, are not used in the process due to their performance and health and safety constraints.

Our Machines, Our Binder, Our ability to apply Ecofill to any kind of construction project (temporary and permanent) and our ability to offer both ‘solidification’ & ‘stabilisation’

In short, solidification is where our technology encapsulates and/or retards the leachability of the contaminants and stabilisation is where our technology reduces the quantity/amount of contaminants in the ground to safe levels. (Full scientific definitions can be found via the Environment Agency).

No. unlike other binding agents, the Ecofill binder is classed as an irritant (just like Ordinary Portland Cement) and is employed in a manner that is safe to the ground and the surrounding environment. We also use less binder compared to others, therefore ecofill typically has a much lower carbon footprint, has less health and safety considerations and is more cost effective.

Absolutely. And this is where Ecofill excels in offering value. There are an estimated 18,000 brownfield sites nationally. We have the ability to work with inert, non-hazardous and hazardous materials either by encapsulating or reducing the contaminants to safe levels all of which are signed off by the regulators. The Ecofill land remediation solution (“R-Ecofill”) is one of our key offerings to land agents and developers nationwide. No more costly export of contaminated soils to landfill. Our technical team can advise on specific contaminants and our solution for each.

This is simple. By using the Ecofill solution, you will drastically reduce the number of lorry movements to and from site thus reducing thousands of kilograms of Co2 emissions from your projects. In addition, particulate matter such as PM10, PM2.5 and Nitrogen Dioxide is significantly reduced. An example of these savings can be found on our about us page.

The sooner the better. Early contractor involvement is recommended to offer a fully optimised site strategy masterplan. Working with our industry partners, we offer an end-to-end service which includes Land Acquisition Support, Site Investigation, Land Remediation, Design, Build and Validation.

Or we can simply provide our affectionately termed “RO/RO” model (Rock On / Rock Off) where our machine arrives on site, processes your material and leaves. We would always recommend early engagement however to allow us to provide you with the best possible added value to your project. 

All ground types are different. In order to achieve the best efficiency from the process the ground ideally needs to have a certain moisture content. If moisture levels are too high, we can introduce a pre-treatment to the ground. Known as our “Pr-Ecofill” process we will ascertain moisture levels prior and implement a plan to achieve best efficiency for the main Ecofill process. We will guide our clients every step of the way.

Ex-Situ (in this instance) is the process of treating clays & subsoils ‘out of’ the ground. In-Situ is treating the clays and subsoils whilst still in the ground which has many limitations such as the depth at which the technology can be introduced and working in confined/hard to reach areas, for example, housing developments and/or railway embankments to name but a few.

Our technology is the only technology with the ability to treat earthworks Ex-Situ offering clients much greater flexibility, catering for any type of construction project.

Yes. Ecofill can work in the design and build of both temporary and permanent earthwork structures. Ecofill is the only methodology of its kind to be able to provide this service to clients & developers who seek value and a sustainable solution for permanent earthwork structures.

As of yet we haven’t quite figured out how to get our machines to the moon, but for now, Ecofill can be used anywhere else on planet earth. Ecofill is available to every kind of construction project ranging from smaller housing developments, medium sized commercial builds right through to large scale industrial projects, offshore windfarm projects and national rail & road infrastructure. We also work with quarries to transform their waste into a marketable product.

EcoFill can be used in low temperatures (3 degrees+) unlike Quick Lime, which generally require temperatures of 7 degrees+ which is typically restricted to the months between March and September. During light rains, EcoFill processing and use can continue as normal. Following compaction, the Ecofill treated subsoil is largely impervious to moisture and it sheds rainwater similar to a paved road. This means that even with hard rains, there are usually only minimal delays before the surfacing can be applied.

We know how much of a problem this has been in the past, especially when corrosive binders are used. These binders will alter the pH and nutrient status of the soil, which results in reduced or the elimination of crop growth and yield. Pre site data is collated, analysed and stored. When temporary structures such as haul roads and compounds are no longer required, based on this data and on our expertise of course, we can formulate a solution to return the pH levels and nutrients to their original status and in some cases even improve on this.

Absolutely. All of our products are designed and produced to national specifications for the DMRB (Design Manual for Roads & Bridges). Based on pre-site investigation, the ecofill Binder is formulated to optimum workability with the site ground type to achieve above and beyond the minimum stiffness modulus and load bearing that is required.

We have thorough testing procedures in place at every stage of the process. All of which are verified and validated by independent & accredited third-party institutes. All reports are made available to the client at every stage of the Ecofill process.

EcoFill can be mixed with subsoils and clays to produce materials that are compliant with the Design Manual for Roads and Bridges and their relevant British Standards. In addition to this the Ecofill material can be produced and designed in accordance with BRE 470 and TWF2019 for use as working platforms.

Our range of products compare to traditional products such as 6F2, 6F5 and Type 1 and Concrete. Equal to and in many cases better than the strength and durability that these traditional products offer. More information can be found on our applications page.

Ecofill has a workability period of up to 10 calendar days (provided stockpiles are sealed). This allows for much greater flexibility in site operations.

After final compaction, EcoFill only requires 24 to 48 hours to cure, this is faster than traditional binders such as cement or quick lime allowing the customer to open up the Ecofill structure to traffic in a shorter period of time. This helps reduce job time and allows surface course materials e.g. our HD layer to be placed in a shorter period of time also. Our technical team are on hand to a guide and assist at any time.

This is simple. By using the Ecofill solution, you will drastically reduce the number of lorry movements to and from site thus reducing thousands of kilograms of Co2 emissions from your projects. In addition, particulate matter such as PM10, PM2.5 and Nitrogen Dioxide is significantly reduced. An example of these savings can be found on our applications page.

No. An experienced and fully trained Ecofill operative will be with you on site to operate the machine at all times. They are there to constantly monitor the process, ensuring safety, efficiency and quality.

No. in fact quite the opposite. Ecofill can reduce your earthworks costs by up to 25%. And did we mention how environmentally sustainable this solution is? Not only will you save on your costs, but you will also achieve your own sustainability targets quicker and help to achieve UK & global net zero goals faster too.
