Waterblocks RT90

WaterBlocks® Rough Terrain Barriers for uneven ground and more substantial working applications. Our Rough Terrain barriers advantages over the Light Duty barriers are: 1. The Arched front face design offers 20% to 30% more anti-flood resistance. 2. The concave-convex side face brings better sealing and stability. 3. Back side's removable structure and support bars could prevent barrier from moving under heavy wave and wind and provide more anti-flood support. 4. Spring lock structure is more convenient to install and more stable 5. Much bigger waterproof strips and anti-slip strips than Light Duty.
