Adcor 500S

Swellable conformable waterstop strip, expanding in contact with water, for sealing joints in monolithic concrete

Product description
Conformable, expanding in contact with water swellable polymer/butyl rubber waterstop. When fully encapsulated by concrete cover, the expansive forces form a waterstop between concrete and strip. The seal is resistant to hydrostatic water pressure, stopping water from entering sub-constructions.

Adcor® is specially developed unique product, that provides better protection than bentonite joints strips and traditional swellable rubber waterstops.

Grace can also ensure continuity of swellable waterstop at deformation and construction joints intersections. This is achieved by linking Adcor®  500Si and Servitite®  AT 200 (Servitite®  AT 200 is manufactured by means of co-extruding PVC with hydrofilic element; see drawing on the reverse side).

Applications

  • Construction joints in in-situ concrete structures.
  • Joints between existing concrete and new casting.
  • Between foundation slab and support wall (e.g., support walls for structural seal sections and steel sheet piles).
  • Joints between pile caps and foundation slab.
  • Pipe penetrations through walls and floors.
  • Casting with concrete over holes.

Advantages

  • controlled volumetric expansion – reduces risk of concrete spalling when swelling;
  • conformable – can be applied even at irregular substrates;
  • retains cohesive strength at both expanded and original shape;
  • when applying, no need for protecting joints with steel mash;
  • resists at least 6 bar hydrostatic pressure (60 m w.c.);
  • volumetric expansion min 100% in cement water;
  • joint overlaps are easily performed;
  • reproducively swelled after wet/dry cycling;
  • contains no sodium bentonite;
  • product can be easily jointed to Grace PVC waterstops at intersections.
