Aggregates for Sewage Treatment Works
Specialist Materials for Drainage, Filtration & Structural Support
Aggregates are essential in the construction, maintenance, and upgrading of sewage treatment works and wastewater infrastructure. At RedRox, we supply a wide range of certified aggregates used throughout these critical environments, from drainage layers to concrete bedding and structural fill.
With reliable nationwide delivery across England, Scotland and Wales, we support everything from large-scale utility frameworks to regional upgrades and emergency repairs.
Where Aggregates Are Used in Sewage Treatment Projects:
Drainage & Filtration Layers
Aggregates such as clean gravel and specialist filter media are used to promote effective drainage and separation in treatment beds, percolation areas, and infiltration trenches.
Washed, single-size gravels (e.g. 10mm, 20mm) ensure optimal permeability and prevent clogging.
Pipe Bedding & Surround
Clean, angular aggregates are used to support and protect pipes within wastewater networks.
We supply Type A, B, and C pipe bedding aggregates, including recycled options, to suit project specifications.
Proper bedding ensures long-term durability and reduces the risk of pipe deformation or settlement.
Structural Fill & Sub-base Construction
Sewage treatment works require stable platforms for tanks, chambers, and access roads.
Aggregates such as MOT Type 1, 6F5, and granular fill are used for foundations, bases, and retaining structures.
Concrete & Precast Production
Aggregates are a core ingredient in the production of precast units, wet wells, and cast-in-place structures.
Supplied in certified mixes, our aggregates meet strict requirements for strength, consistency, and cleanliness. a
Key Benefits of Using Aggregates in Sewage Infrastructure:
Supports load-bearing structures such as tanks, kiosks, and concrete slabs
Enhances drainage and filtration, ensuring effective wastewater flow and treatment
Protects buried utilities from shifting and pressure
Reduces maintenance and risk of failure in high-load or corrosive environments
Improves ground stability around critical assets and access routes
