Concept / Description

Retail drainage services are defined as the systematic application of diagnostic, restorative, and preventative techniques to manage complex drainage systems in retail environments. The concept pivots on three primary functions:

Diagnosis:

CCTV Drain Surveys: High-definition cameras are inserted into drainage systems to capture detailed images of internal defects, blockages, and potential points of failure. The footage is evaluated through standardised defect coding systems such as BS EN 13508, ensuring that even subtle issues are detected.
Dye and Smoke Testing: These methods trace the flow of water within the system, enabling technicians to pinpoint blockages and understand connectivity within the drainage network.
Drain Mapping: Techniques employing sonic devices and manual tracing facilitate the creation of accurate drainage maps, which serve as vital tools for planning interventions.

Restoration:

Mechanical Unblocking: Methods such as rodding and high-pressure jetting are employed to dislodge obstructions, whether caused by FOG (fat, oil, grease), tree roots, or debris.
No-Dig Pipe Relining: When internal pipe damage is observed, a resin-impregnated liner may be inserted to reinforce and seal the pipe without extensive excavation.
Root Removal: Techniques focused on the cutting or chemical treatment of tree roots prevent recurrent blockages that are common in urban retail settings.

Preventative Maintenance:

Scheduled Inspections: Regular diagnostics, often conducted using CCTV and sensor-based systems, help identify emerging issues well before they escalate into emergencies.
Maintenance Contracts: fixed-price agreements that encompass regular cleaning, jetting, and grease trap management contribute to system longevity, reducing the frequency and severity of breakdowns.
