Flood and Water Management Act
Hydrology and SuDS: The Mathematical Reality of Permeable Resin Systems For modern urban developments, the management of surface water runoff is a critical engineering challenge. As “hard landscaping” continues to replace natural soil, the risk of “flash flooding” increases. Resin-bound surfacing is often marketed as SuDS (Sustainable Urban Drainage Systems) compliant. However, compliance is not […]
Why Some Resin Driveways Fail
Forensic Failure Analysis: A Structural and Chemical Post-Mortem of Resin-Bound Surfaces When a resin-bound surface fails, it is rarely the fault of the aggregate itself. Failure is typically a result of a breakdown in the interface mechanics or a chemical interference during the curing phase. For the professional specifier or civil engineering student, diagnosing these […]

Aromatic Binders: The Benzene Ring Weakness Aromatic resins (often derived from MDI – Methylene Diphenyl Diisocyanate) are the “standard” or “budget” resins found in the UK market. At a molecular level, Aromatic isocyanates contain Benzene rings. These rings are highly efficient at absorbing Ultraviolet (UV) light. When sunlight hits an aromatic binder, the energy from […]
