Waterstops

PVC is the industry standard for flexible waterstops, which are typically embedded across and along the joint. PVC is the most versatile waterstop material, offering the broadest design selection and is accepted under the ACI 350 "Code Requirements for Environmental Engineering Concrete Structures". It has great inherent elasticity and is resistant to many waterborne chemicals. It will not discolour concrete or produce electrolytic action.

Hydrophilic joint sealing systems, such as SikaSwell® profiles and sealants, are water stops designed to swell and be used in watertight concrete structures for the systematic sealing of construction joints. Upon contact with water, SikaSwell® Waterstop creates swelling pressure within the construction. This inflation pressure seals the construction and prevents water penetration.

Construction joints in concrete structures are often complex or difficult to reach. Sika offers a complete range of injection hoses that are easy and safe to install. Injection hoses provide tight seals and offer a complete solution for maintenance in the event of a future leak.

High performance and versatile sealing system for construction joints, expansion joints, connection joint and cracks. This system allows variable and large amplitude movements in one or more directions, while maintaining the watertight seal.
