Superwell 47B controlled swell gasket & waterstop

Superswell 47B waterstop is for waterproofing concrete basements, pools, precast infills.

A controlled hydrophillic swellable gasket that expands in a controlled fashion when exposed to moisture, forming a seal in concrete joints.

Can be exposed to moisture for days before the swelling starts. No need to worry about a shower of rain destroying newly installed water stops.

HOW IT WORKS

Controlled expansion waterstop

MARKHAM SUPERSWELL 47B WATERSTOP is a unique sealing gasket that expands in a controlled fashion when exposed to moisture, forming a compression seal in concrete joints

Orders before 2pm will be dispatched the same working day. Orders after this cut off will dispatched the following working day

Key benefits
desktop-banner-product
Built-in delay system to stop premature expansion

Allows concrete to gain full strength before expansion, and then the butyl hydrophilic polymar based gasket activates after approximately 5-10 days of constant exposure to water.

Does not lose integrity over time in water

Unaffected by repeated wet and dry cycles. 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.

Bonds to both concrete surfaces

Very easy to handle and install.. No on-site welding required as with PVC waterstops. Excellent adhesion, can be bedded into wet concrete and is suitable for use in horizontal and vertical joints.
