Please see below a list of all our mix designs we have to offer and there uses for each product Each mix design can be altered with admixtures and fibres to be suitable for each project

C8/10 (Gen 1)This concrete mix can be used for drainage works, floor blinding, Foundations for steps and void filling. Useful for a firm base where no structural strength is required.
C12/15 (Gen 2)This concrete mix can be used for house floors where a non – permanent finish will be applied (E.g. Carpet). It can be used for kerb bedding where there is no risk to excessive force for example a driveway.
C16/20 (Gen 3)This Concrete mix can be used for Domestic floors and bases with lighter overall loads including shed bases.
C20/25 (ST2)This concrete mix can be used for lightweight, commercial and domestic projects including shed bases, garden wall foundations, Ground foundations and reinforced bases, infills and kerbing.
C25/30 (PAV1/ST3)This concrete mix can be used for Commercial and Domestic projects including footings and foundations, Pathways, roadways for yards.
C28/35 (PAV 2)This concrete mix can be used for commercial structures with heavy use, piling, external slabs walls, yard and barn containment areas.
C32/40This concrete mix is a strong commercial concrete used for HGV Parks, Agricultural yards and chemically harsh environments.
C35/45Typically used in specialist projects where high strength and support is key for example areas with aggressive chemicals or high abrasion levels are present. This is a polymer – modified concrete that has a very high flow rate typically 700 to 800mm.
Self-Levelling Concrete C35/45Works very well with slabs and requires very little work for a smooth finish.
C40/50Concrete for specialised strength for example crane bases.

Additional Additives

AdditivePurpose Additive & Purpose
Water Reducing Plasticiser (WRA)Reduce water content of mix without compromising consistence or strength. Water Proofer Agent Makes concrete waterproof by filling voids.
Set AcceleratorIncrease setting time and early age strength. (Used in cold conditions)Air Entrained Agent Improves Freeze/Thaw Durability. Used in harsh Conditions (Roads /Paths)
Retarder Delay setting time and hardening of concrete. (Used in hot Conditions)Concrete Fibres Improves Durability, Fire Resistance and reduced risk of cracking.
