SERVISEAL®
External PVC waterstop system for passive protection of movement joints and construction joints in reinforced concrete structures
Product Applications
SERVISEAL® is a passive external PVC waterstop system manufactured in a range of sizes for protecting joints in concrete basements and sub-structures.
SERVISEAL® external flexible waterstop systems have a proven design using four T shaped ribs for solid embedment in in-situ concrete which create a valve action to seal the water path, and are suitable for horizontal and vertical applications. Being cast into the outside water face prevents the ingress of moisture and protects the outer layer of reinforcement from corrosion. Location on the outside face of a concrete member also promotes better compaction of the concrete around the ribs of the SERVISEAL® since it is free from reinforcement congestion and the weight of wet concrete makes consolidation easier.
SERVISEAL® can be used for non-suspended slabs in water retaining structures such as reservoirs, swimming pools and sewage treatment tanks.
Advantages
- Proven design - the original external waterstop used extensively in water excluding and water retaining structures
- Flexible - will accommodate movement during construction and service life
- External seal - protects reinforcement from water ingress
- Pliable - remains flexible at low temperatures
- Four ribs - provide extended and tortuous water path
- Stabilising/Nailing flange - allows fastening without damaging waterstop and prevents displacement or folding of ribs during concreting
- Pre formed junction pieces - factory made range of standard junction pieces.
Limitations
SERVISEAL® is not suitable for walls of water retaining structures which should always have SERVITITE® waterstops cast centrally in the concrete wall to resist the internal water pressure.
Installation
A continuous waterstop network should be used at all joints to prevent the ingress of moisture using only factory produced fabrications for changes of direction or profile with site jointing limited to simple butted welds. Before concreting, waterstops must be clean and free from concrete laitance, oil, grease or any other contamination that might prevent a good waterstop to concrete bond.
The waterstop network should be loose laid direct on to the blinding concrete with timber stop-ends or securely fixed into the vertical shutters using mechanical fixings staggered at 500 mm cross centres.
