Overview

Targeted patch capability without adding another machine

Spot Adapter turns existing Sewerbot equipment into a fast, precise patch workflow for localized failures where full-run lining is unnecessary.

Key Benefits

  • Works with both Sewerbot and Sewerbot Compact — no additional unit required.
  • Only the adapter changes per diameter; repair length is flexible from ~40 cm to 4 m.
  • Disposable bladder after each repair — no wear-and-tear management.
  • Eliminates separate dedicated patch rigs in everyday spot-repair operations.
  • Uses the installed control stack and tooling for simpler deployment.

Applications

Where Spot Adapter delivers the clearest field advantage

Localized Defect Repairs

Deploy targeted patches where localized failure makes full-run rehabilitation unnecessary.

  • Optimized for short damaged segments where precision and speed are critical.
  • Supports fast return-to-service on common municipal and commercial defects.

Constrained Access Interventions

Run spot repair in difficult access conditions with compact setup and stable in-pipe control.

  • Designed for practical operation where space or access limits larger workflows.
  • Keeps on-site handling efficient without adding dedicated patch equipment.

Fleet Utilization Expansion

Turn existing Sewerbot capability into a complete patch workflow without extra platform overhead.

  • Eliminates the need for a separate dedicated patch rig in most use cases.
  • Extends platform value across both full-run and spot-repair job types.

Workflow

Fast targeted repair flow for localized failures

Spot Adapter is structured for quick intervention and dependable patch quality, helping teams close localized defects with less setup overhead.

Step 01

Prepare

Configure the patch workflow on the existing control stack and tooling.

Step 02

Position

Place the repair section exactly at the defect location in-pipe.

Step 03

UV Cure

Execute controlled curing with the integrated UV head process.

Step 04

Verify

Confirm patch quality and reopen the line with repeatable QA checks.
