Internal PVC waterstop system for passive protection of movement joints and construction joints in reinforced concrete structures.


SERVITITE is an internally cast specially formulated PVC waterstop system manufactured in a range of sizes for use in reinforced concrete structures. Being cast into the centre of the concrete member, SERVITITE waterstops will provide resistance against high hydrostatic pressure from both faces.


  • Robust profile - large solid circular end bulbs promote better anchorage and embedment into concrete and simplifies site jointing
  • Flexible - will accommodate large movements during construction and service life
  • Pliable - remains flexible at low temperatures
  • Valve action - created by concrete shrinkage around end bulbs and adjacent fin formation
  • Thick web - 10 mm thickness prevents folding over and displacement during concrete pouring
  • Common section for easy installation - for construction and expansion joints subject to thermal movement and deflection
