Clearcal

See the cure. Go the distance.

The evolution of lining is here: stronger, longer, smarter. CLEARCAL combines SE and XT variants in one platform so crews can choose long-run efficiency or reinforced durability without changing process philosophy.

Calibration hose overview

Built for blind-shot and full-shot installations.

CLEARCAL is engineered for teams that already run CIPP daily and need reliable behavior in hard-to-access jobs. For Single-Access Relining (Blind Shot), it performs in both full-shot configurations and when crews bond (glue) it to the liner end. The result is steadier pressure control, cleaner finishes, and fewer corrective interventions in the field.

Single-Access Relining (Blind Shot) ready

For pipes with a closed or inaccessible far end, CLEARCAL enables true single-entry relining: run full-shot installations or bond (glue) it to the liner end for blind-shot workflows. Ideal for hard-access locations with fewer setup compromises.

Why contractors pick SE

High-transparency PVC supports real-time visual control, while long continuous lengths reduce changeovers on long sections.

Why contractors pick XT

Reinforced sewn and seam-taped construction is built for tougher, pressure-demanding installations where robustness is critical.

Variant selection

Choose the sleeve profile by project pressure.

Standard Efficiency

CLEARCAL SE

Pipe Range

DN70-DN150

Run Length

Up to 300m (984 ft)

Material

High-transparency PVC, single or double weld options

Daily long-run cycles where reducing changeovers and scrap is the primary lever.

  • Supports visual process control during inversion and cure.
  • Designed for high-volume throughput with stable handling.
  • Prioritizes operational continuity across large linear sections.

Xtra Tough

CLEARCAL XT

Pipe Range

DN100-DN200

Run Length

Up to 100m

Material

Heavy-duty reinforced sewn and seam-taped construction

Pressure-intensive jobs and rugged conditions where sleeve robustness is non-negotiable.

  • Built for harsher operating environments and tougher loading.
  • Maintains dependable cure behavior across supported methods.
  • Reinforcement profile helps crews manage demanding field setups.

Engineering pillars

Designed for longer runs and cleaner finishes.

SE and XT share one core engineering direction so crews gain predictable behavior from inversion to cure completion, regardless of the selected sleeve profile.

Capability 01

Running longer

Low-coefficient-of-friction exterior supports easier inversion and steadier advance.

Capability 02

Curing faster

High spectral transmittance improves UV-A and blue-light penetration inside the sleeve wall.

Capability 03

Finishing smoother

High-frequency welding creates lower-profile seams to help reduce fin effect at completion.

Capability 04

Inflating evenly

Low opening pressure design helps prevent pre-cure flat spots and improves shape consistency.

Technical specifications

Field-ready metrics for both variants.
