Hawkes Group specialises in supplying sub-bases using sustainable recycled materials.
Type 1 Recycled Aggregate
A mixture of primary and recycled aggregate, combining the advantages of both.
6F5 Recycled (Formerly 6F2 Recycled)
Typically used for capping sub formations prior to laying Type 1 or Type 2 sub-base. Well graded material ranging from 125mm to dust.
6F4 Recycled (Formerly 6F1 Recycled)
Finer Capping Layer used in the same applications as 6F5 but with a finer grading. Generally 50mm to dust and evenly graded.
Waste product of road resurfacing, used for hard standing and ideal as a finished surface for building sub-bases and farm tracks. Not suitable for drainage trenches.
A crushed recycled material with good cohesive qualities, often used as a hard core for temporary roadways and as a sub-base. Normally supplied as a 0-50mm and often referred to as a Type 4.
Type 3 Recycled (formerly Type1x Recycled)
40mm unbound mixture utilising recycled aggregate. Used for sub- base applications as per the Specification for Highway Works, clause 805. Generally open graded with a reduced amount of fines (not zero fines) to improve drainage in comparison to Type 1. Widely used for sports pitches, equestrian arenas, driveways and tennis courts where drain blockage may be an issue, particularly where SUDS (Sustainable Urban Drainage Systems) legislation is imposed. Also used as a sub-base material in hard standings, haul roads, paths and patios.
