Debris and stone impact
Typhoons, heavy rain, and water-level changes can drive stones, driftwood, and debris against pier surfaces.
BayBrane® Application | Pier and Bridge Protection
Piers face river scour, debris impact, water-level changes, and temperature stress. Without protection, concrete wear, crack growth, corrosion, and durability loss may occur. BayBrane® forms a continuous elastic layer for waterproofing, impact protection, and long-term bridge durability.
Why pier protection matters
BayBrane® is applied to pier, bridge, and river environments to reduce surface damage from long-term scour and external impact.
Typhoons, heavy rain, and water-level changes can drive stones, driftwood, and debris against pier surfaces.
Continuous water exposure requires stable adhesion and durable surface protection.
Wear, cracks, and weak points may increase maintenance costs and reduce durability.
Water entering concrete may increase reinforcement corrosion and structural deterioration.
Project timeline
From Taiwan High Speed Rail piers to international bridge projects, BayBrane® applications are supported by long-term exposure and field testing.
Hydroseal introduced BayBrane® materials and technology to Taiwan for waterproofing and special engineering protection.
Interactive layer model
Pier protection is more than waterproofing. It uses a continuous elastic layer with compression strength to reduce damage from stones, debris, scour, and weather exposure.
BayBrane® cures quickly after spraying and forms a uniform orange-peel, non-sag membrane. A penetrating primer improves bonding to concrete or metal substrates.
This application page focuses on pier impact protection, bridge protection, river scour, and severe engineering environments.

Key points on pier protection, bridge protection, material performance, and project references.
BayBrane® is a high-grade elastomer without additives. Independent tests at different temperatures verify its waterproofing and protection performance.
For piers exposed to scour, debris, and stone impact, BayBrane® forms a continuous elastic layer that helps reduce surface damage.
BayBrane® passed a 100,000-cycle repeated compression test without deformation.
After three years, a field sample passed another 100,000-cycle test. After seven years, key properties remained above BayBrane® standard values.
At 50% compression deformation, BayBrane® can reach 150 kg/cm² compression strength while retaining elasticity after repeated compression.
BayBrane® was used with Taiwan High Speed Rail in 2007 for pier protection against long-term river scour.
Related applications include Minjiang Bridge piers, Harbin high-speed rail bridges, and Macau LRT elevated bridge structures.
