CONQOR 87B | WATERSTOP GASKET
Weather-resistant waterstop gasket.
CONQOR 87B is designed to activate after 8-24hrs. Prevent premature gasket failures.
- Delayed swell (8-24 hours)
- Weather-resistant
- High in-process visibility
CONQOR 87B | WATERSTOP GASKET
Controlled expansion waterstop gasket, designed to activate after 8-24 hours.
Stop premature expansion! Traditional waterstops can swell prematurely in wet conditions while neighbouring slabs are being poured. This premature expansion reduces or eliminates the gasket’s useful effect.
CONQOR 87B waterstop is a butyl hydrophilic polymer-based gasket that has a built-in delay system to activate after approximately 8-24 hours of constant exposure to water.
- 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
Suited for expansion joints, slab connections, vertical or horizontal situations, and around penetrations.

Who it helps.
Ideal Solution for
Concreters & formworkers.
CONQOR 87B does not swell prematurely, avoiding the need of replacement or rework. No onsite welding. No special equipment. CONQOR 87B is a self-healing jointing material.
Also HELPS
Project & Site Managers.
CONQOR 87B is weather-resistant and can be left in-situ until neighbouring slabs are poured. Avoid delays from prematurely swollen gaskets. Avoid concrete joint blowouts.
USED by
Architects & Construction Designers.
CONQOR 47B and CONQOR 87B can be included with confidence into multi-part basement or deck structural waterproofing systems. Also suited to car parks, tunnels, pits, box culverts, and new-to-old concrete interfaces.
works for
Asset owners.
CONQOR 47B and CONQOR 87B can be relied on for long-term waterproofing joint protection.
CONQOR 87B | WATERSTOP GASKET
How it helps.
CONQOR 87B is a controlled expansion waterstop gasket, designed to activate after 8-24 hours.
CONQOR 87B | WATERSTOP GASKET
No on-site welding
Save time and labour costs. No special process or equipment for welding. Very easy to install. CONQOR waterstops can be applied with simple equipment. Non toxic and requires no special handling.
CONQOR 87B | WATERSTOP GASKET
No risk to the concrete
Built-in delay system to stop premature expansion. No loss of integrity of waterstop. Allows concrete to gain full strength before expansion. Does not absorb water from the fresh concrete poured against it, eliminating the risks of the gasket expanding and causing the curing concrete to spall/de-bond directly above the gasket.
CONQOR 87B | WATERSTOP GASKET
Integral to multi-part waterproofing
Tested to withstand a 40-metre head of pressure; and because of its butyl properties, CONQOR 87B actually bonds to both concrete surfaces.
CONQOR 87B | WATERSTOP GASKET
HOW IT WORKS.
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.

Hydrophylic polymer-based
CONQOR 87B waterstops are butyl hydrophilic polymer-based gaskets, that have a built-in delay system that activates after approximately 8-24 hours of constant exposure to water.
CONQOR 87B | WATERSTOP GASKET
Weather resistant
CONQOR 47B and CONQOR 87B waterstops feature a delayed swell, and resistance to wet-dry cycles, ensuring they stand up to fluctuating site weather conditions.
CONQOR 87B | WATERSTOP GASKET
No special handling
CONQOR 87B is non-toxic; does not require welding; and does not require specialist installation equipment.
CONQOR 87B | WATERSTOP GASKET
High performance
CONQOR 87B has been tested to withstand 70m head of water pressure. CONQOR 87B continues functioning through multiple wet/dry cycles with no loss in performance. Suitable for horizontal and vertical joints. Bonds to concrete surfaces. Designed to resist premature expansion during construction.

CONQOR 47B & CONQOR 87B compared
The key difference between CONQOR 47B and CONQOR 87B is the swell delay time. The magenta-coloured CONQOR 87B swells in 8-24 hours. The cyan-coloured CONQOR 47B swells in 3+ days. CONQOR 47B tolerates longer exposure to rain and ponding prior to pour, while CONQOR 87B is the faster swelling option for projects requiring faster activation.

The delayed swell feature is important because it means the gasket will not expand rapidly if it comes into contact with water before the next pour.
