WATERSTOP GASKET for CONSTRUCTION JOINTS
CONQOR 87B is designed to activate after 8-24hrs
CONQOR 87B is a delayed-swell waterstop gasket, designed to activate after 8-24hrs
CONQOR 87B waterstops are butyl hydrophilic polymer based gasket, that have a built-in delay system that activates after approximately 8-24 hours of constant exposure to water.
CONQOR waterstops are manufactured utilising a specialised mixing process which encapsulates hydrophilic materials into a rubber base creating a controlled, moisture-activated gasket. This gasket has the structural integrity of a rubber-based sealant; the features of a butyl sealant; as well as the ability to expand to create a SELF-HEALING JOINT MATERIAL.

- DELAYED SWELL
- WEATHER RESISTANT
Why select CONQOR waterstops?
CONQOR waterstops feature a delayed swell, and resistance to wet-dry cycles, ensuring they stand up to fluctuating site weather conditions.
CONQOR 87B WATERSTOP GASKET
BUILT-IN DELAY SYSTEM (8-24 hours)
Stop premature expansion! Traditional waterstops can swell prematurely in wet conditions, while waiting for neighbouring slabs to be poured. This premature expansion reduces or removes the useful effect of the gasket.
- For use in horizontal and vertical joints
- Excellent adhesion, can be bedded into wet concrete
- No compact or displacement problems
- Unaffected by repeated dry cycles
- Bonds to both concrete surfaces
- Does not lose integrity over time in water

How CONQOR 87B GASKET works
CONQOR WATERSTOPS are unique sealing gaskets that expand in a controlled fashion when exposed to moisture, forming a compression seal in concrete joints.
CONQOR 87B has up to 10 days delay - ideal for lift pits, basements and in-ground construction
We recommend discussing your specific project needs with MARKHAM to select the correct product.
CONQOR 87B WATERSTOP GASKET
EASY TO INSTALL
- Ensure the surface where CONQOR 87B WATERSTOP gasket is to be installed is smooth, to ensure a complete contact for gasket.
- CONQOR 87B WATERSTOP gasket is to be placed on the positive water ingress side of any reinforcing, to ensure structural reinforcing is protected from moisture ingress long-term.
- Unroll required length of CONQOR 87B WATERSTOP gasket, apply contact adhesive to the exposed side, and then apply contact adhesive to the concrete surface to have the gasket installed. Allow to tack-off. NOTE: Use contact adhesive CS1550, CONQOR FIX, Sabrebond SMP60 or similar.
- Install CONQOR 87B WATERSTOP gasket on to concrete, apply pressure to ensure complete contact with surface.
- Concrete nails may be utilized as an alternative to adhesive.
- Join lengths of CONQOR 87B WATERSTOP gasket, by cutting a 45° splice and kneading together to form continuous gasket.
- Ensure the CONQOR 87B WATERSTOP gasket is securely fixed to the surface, prior to concrete being poured, as any gap between gasket and
surface will result in the waterstop performance being compromised. - If the surface is rough, ensure that there are no gaps between the surface of the concrete and the 47B gasket
