Limestone Ultiflow

Our Limestone Ultiflow is a specialist free-draining limestone aggregate produced for soakaways, attenuation systems, permeable groundwork, and drainage applications where rapid water movement is required through the installed stone layer. The controlled low-fines grading creates larger interconnected voids between the aggregate which helps increase water storage and flow capacity beneath drainage systems and permeable construction works. Groundworkers and civil contractors regularly use this material where conventional compacting aggregates would restrict drainage performance or reduce long-term permeability.

We supply this limestone aggregate for domestic, commercial, and infrastructure groundwork projects across Manchester and surrounding North West areas. Ultiflow limestone is commonly installed beneath permeable paving, around attenuation crates, within soakaway systems, and across sustainable drainage applications where maintaining water movement is critical to overall system performance. The angular stone structure also helps the aggregate remain stable within excavation areas while still allowing effective water transfer through the installed layer. Its drainage-focused grading makes it particularly suitable for SuDS-related groundwork and modern permeable surface construction.
