BRIEF INTRODUCTION rubber waterstop belt :
Our company is absorbed in producing rubber water stop series and research and development. We could produce various rubber water stop series. And our products all have high quality. Rubber water stop use high elasticity to make elastic deformation under load. Thereby, it could make seal sturdy, and prevent structure leak and seepage in order to shock absorption.
| Applications: | Rubber water stop is widely used in underground installation, tunnel and culvert, impounding reservoir, metro, and retaining dam and so on. |
| Features: | 1. The rubber water stop strip will expand when getting in touch with water, so allowing it to come into closer contact with the concrete, creating a better water-stop result.2. Different thicknesses structure is adopted for the cross section, which is divided into the high-strength area, the waterproof area and the installation area, allowing for uniform and reasonable stress for all portions.3. At installation area add installing hole, it could facilitate fixed with adjacent reinforced, and not produce shifting. Construction is convenient, positioning installation isfirm. |
