AT System - SERVITITE® AT 200/ SERVISEAL® AT 240
Verified by manufacturer today
Dual function PVC waterstop system with co-extruded hydrophilic bulbs to provide a unique combination of active and passive protection for joints in concrete.
Application
Internal and external applications. For water excluding and retaining structures such as basements, reservoirs, sewage treatment works, etc.
Serviseal® AT 240:
Can be cast on the external face for water excluding structures such as basements and sub structures or ground bearing slabs only of water retaining structures.
Servitite® AT 200:
An internally placed waterstop which is cast centrally in the concrete to resist internal and external water pressure.
Description
High security Polyvinyl chloride (PVC) waterstop system with coextruded hydrophilic bulbs to provide a unique combination of active and passive protection for joints in concrete .The two profiles can be combined, using factory produced transition junctions where Serviseal® AT 240 is used on the base slab and Servitite AT 200 is used within walls.
Features and benefits:
- Combines advantages of PVC waterstop with active hydrophilic elements to provide maximum resistance to water pressure.
- Hydrophilic elements swell in contact with water to plug voids formed by normal concrete shrinkage.
- Location of active element is designed to prevent lateral migration of water along waterstop bulb.
- Protective coating prevents premature swelling of hydrophilic element whilst exposed and for 12 to 18 days after casting to avoid spalling of fresh concrete.
- Easy installation.
