Weatherproof & UV Resistant: UV-treated material withstands strong sunlight and harsh conditions for long-term outdoor use, resisting aging and maintaining stability.
Safe & Eco-friendly: Made from non-toxic, eco-friendly materials that are harmless to water quality and aquatic life, safe for storing potable water or aquaculture use.
The PVC bladder works by using hydrostatic pressure to simulate structural loads. In use, the foldable blue PVC bladder is placed under a bridge bearing or support and gradually filled with water. As the bladder inflates, it applies an even pressure across the structure. Because water has a relatively low density, the filled bladder is lighter and easier to handle than solid weights. The even pressure from the filled bladder helps eliminate non‑elastic deformations in the foundation and supports, assisting in controlling the bridge geometry.
Reinforcement frame: Polyester ropes are sewn around the bladder's edges.
The rope frame distributes tension evenly, limiting over-expansion and maintaining a stable shape.
Anchoring points: the rope ends can be tied to supports or structural elements to secure the bladder during filling.
Durable material: high-quality PVC fabric with excellent resistance to abrasion, puncture, and tear.
Foldable and portable: the bladder can be drained and folded for easy transport and repeated use.
Cost-effective & eco-friendly: lower cost than concrete or steel weights and designed for multiple reuse cycles.
Bridge preloading tests: simulating dead loads on arch or girder spans in new bridges.
Static load testing for large structures: applying uniform pressure to features like factory roofs, stadiums or elevated highway sections.
Support and foundation checks: loading bridge piers, bearings or deep foundations to verify capacity and settlement behavior.
Other civil engineering uses: for example, preload on precast tunnel segments or soil filling stabilization.
Quality management: manufactured under ISO 9001:2015 quality system.
Independent testing: third-party labs (e.g. SGS, TÜV) can verify material strength and seal integrity.
Standards compliance: design and testing follow industry guidelines (e.g. LEEA 051); type approvals from BV, DNV, ABS, CCS available
