Adeka KM-String KM6MM 165' Case
Adeka Ultraseal KM-String is a chemically modified natural rubber (vulcanized) product. The manufacturing process chemically bonds a hydrophilic agent to the rubber. This permits the seal to undergo controlled expansion when exposed to moisture. This expansion capability provides a "double locking" waterstop.
- Excellent waterstop for repairing leaks in sheet piles interlocks
- Performs in joints of varying sizes
- Environmentaly safe

Adeka Ultraseal KM-String KM6MM Hydrophilic Waterstop 165 ft Case
Adeka Ultraseal KM-String KM6MM is a chemically modified natural rubber hydrophilic string waterstop. It expands approximately three times by volume when exposed to moisture, providing a double-locking seal. The 6 mm diameter is suited for larger gaps. Packaged 165 feet per case. A smaller 4 mm version is available as the Adeka KM-String KM4MM 165 ft Case.
Key Features
- Chemically modified natural rubber with bonded hydrophilic agent.
- Expands approximately 3 times by volume (about 170% volume change).
- String form allows insertion into joints, cracks, and penetrations.
- Diameter can be reduced about 40% when stretched for easier placement.
- Excellent durability and resistance to chemical contaminants.
- Vulcanized construction.
Applications
- Waterproofing sheet pile interlocks, cracks, and CIPP pipe.
- Sealing piping penetrations and irregular joints.
- Stopping active leaks where string insertion is practical.
- Joints where string size is approximately 1.2 times the gap width.

Frequently Asked Questions
What is the difference between KM6MM and KM4MM?
KM6MM is approximately 1/4 inch diameter for larger gaps. KM4MM is approximately 3/16 inch. Both expand about three times by volume. See the Adeka KM-String KM4MM 165 ft Case.
How should string size be selected?
String diameter should be about 1.2 times the joint or gap width. Stretching reduces diameter by roughly 40% for insertion, then recovery provides initial compression.
Where is KM-String typically used?
Sheet pile interlocks, cracks, CIPP pipe, piping penetrations, and other locations where a flexible hydrophilic string can be inserted.
Does it expand in all directions?
Yes. Expansion occurs in diameter and length and follows the path of least resistance.
