The Ecofill structural materials are produced, tested & validated to meet all the National specification requirements & performance levels for Highways & Earthworks as laid out by the Standards for Highways, Manual of Contract Documents for Highways Works (MCHW), Specification for Highways Works, Series 600, 800 and/or BSEN 14227.
Ecofill end products surpass the minimum structural requirements of:
100%CBR / 335 MPa for Surface Layer (Ecofill HD / Heavy Duty)
30%+CBR / 150 MPa for Sub-base Layer (Ecofill 50)
15%+CBR / 100 MPa for Capping Layer (Ecofill 75)
Ecofill Product Specifications are fully tested & accredited by independent laboratories.
AECOM, the world’s trusted infrastructure firm, which is currently commissioned by the UK Government in the re-writing of various sections of the Manual of Contract Documents for Highways Works, Specification for Highways Works, has also been independently commissioned by Ecofill to produce our comprehensive Quality Management Plan.
This Quality Management Plan covers the design, production and quality control of the Ecofill products, which ensures that the Ecofill products meet the relevant National and European standards for Highways and Earthworks
Ecofill 75 is a Class 9 stabilised material produced and tested to the Standards for Highways, Manual of Contract Documents for Highways Works (MCHW) Volume 1, Specification for Highway Works 600 Series. Ecofill 75 is non-frost susceptible and when compacted, will cure and achieve a stiffness modulus of 15% CBR or 100MPa.
Ecofill 75 can be used as capping and fill layers for earthworks structures and in adoptable Highways.
Ecofill 50 is a Class 9 stabilised material produced and tested to the Standards for Highways, Manual of Contract Documents for Highways Works (MCHW) Volume 1, Specification for Highway Works 600 Series. Ecofill 50 is non-frost susceptible and when compacted, will cure and achieve a stiffness modulus of 30% CBR or 150MPa.
Ecofill 50 can be used as in the same layers as Ecofill 75 however, due to its higher stiffness modulus, it can also be used as the subbase layer in non-adoptable earthworks structures.
EcoFill HD (Heavy Duty) is a Hydraulically Bound Mixture produced to SHW 800 Series Clauses 830, 831 or 832 and BS EN 14227- 5. EcoFill HD has a typical compressive strength of C8/10+ and is non-frost susceptible.
Ecofill HD can be used as Capping, Fill, Subbase and Base layers in earthworks structures and in adoptable Highways.

The Installation and Maintenance of our Ecofill products require a similar approach and methodology to that of traditional roads and foundations construction. This includes Storage, Compaction, Inclement Weather, Water Tables, Drainage etc and additional applications such as Induced Cracking of Ecofill HD.
