The Challenge
Vannamei shrimp aquaculture operation suffered 30-40% loss from water seepage into surrounding soil — destabilizing pH, salinity, dissolved oxygen. Earthen liners eroded each season requiring expensive re-grading. Survival rate dropped to 60-65%.
Our Solution
Substrate prepared via mechanical compaction + geotextile underlayment. Applied 3mm food-grade pure polyurea using JYYJ-H-V6T at 36 MPa, NSF/ANSI 61 compliant grade for aquatic environments. Seamless coverage across 24 production ponds. Cured in seconds, returned to brood-stocking within 48 hours.
What Pioneer Delivered
Not just a machine — a matched system, a trained crew on site, and after-sales backing end to end.
- An on-site survey of pond geometry, slopes and fittings with a substrate-preparation plan before any spray — so the liner bonds to a stable base and does not punch through.
- A single-source system — JYYJ-H-V6T machine and food-grade NSF/ANSI 61 polyurea matched, tuned and warranted together, not a sprayer and a material bought from three suppliers who blame each other.
- A spray crew trained to hold even 3 mm thickness across sloped banks and humid-climate gel timing — the hard part of polyurea is the operator, and we own that skill.
- Holiday-tested QA and a pond-by-pond schedule built around the customer's production cycle — ponds went back to brood-stocking in under 48 hours, keeping the harvest calendar intact.
- Ongoing remote support for ratio and climate tuning, plus easy re-order of the exact matched food-grade material — lining the next pond block is a phone call, not a new project.
Execution Process
-
1 · Substrate Prep & Compaction
Each pond bed and bank is shaped, mechanically compacted and overlaid with a geotextile underlayment to give the membrane a stable, puncture-resistant base. Slopes and inlet/outlet fittings are detailed so the polyurea can run seamless from floor to crest.
-
2 · Machine Setup & Material Check
The JYYJ-H-V6T high-pressure rig is brought to 36 MPa with heated hoses, and the food-grade NSF/ANSI 61 polyurea is verified on test panels for full cure and adhesion. Gel time is tuned for the humid Mekong Delta climate before lining the first pond.
-
3 · Polyurea Spray Lining 3 mm
Hand-spray 3 mm of food-grade pure polyurea over the prepared bed with the JYYJ-H-V6T at 36 MPa, building one seamless monolithic liner per pond with no welds or overlaps to leak. The few-second gel lets the crew coat sloped banks and detailed fittings in a single continuous pass.
-
4 · Cure & Return to Stocking
Polyurea is tack-free in seconds and water-ready fast; the liner is holiday-tested for pinholes before filling. Ponds are flushed and returned to brood-stocking within 48 hours, with no inert leaching to disturb pH, salinity or dissolved oxygen.

Applications
Polyurea Waterproofing
Fast-curing 100% solids polyurea coating for roofs, terraces, pools, and containment. Seamless waterproof membrane with extreme elongation and tear strength.
Tank Lining Equipment: High-Pressure Polyurea Spray Machines
Spray equipment for tank & cistern relining contractors — Pioneer JYYJ plural-component machines at 25–36 MPa with 1:1 ratio control for holiday-free application.
Why This Model Is Commonly Selected
The JYYJ-H-V6T adds a 7-inch PLC touchscreen to the hydraulic V6 platform for precise temperature and pressure control — useful for tank lining, industrial flooring and abrasion-resistant coatings where consistent film thickness matters.
