Adeka Ultraseal KM-3030M Hydrophilic Waterstop
Adeka Ultraseal KM-3030M is a hydrophilic vulcanized rubber strip with embedded stainless mesh for expansion joints, isolation joints, and thick cold joints. Mesh-directed swell runs about 3 times by volume, and movement is intended not to exceed 1/2 in. Use KM-3030M where the wall or slab is at least 1 ft thick, including high-head work such as dams.
Key Features
- Expansion joints with movement not exceeding 1/2 in
- Stainless mesh directs swell through the joint
- Wall or slab at least 1 ft thick
- About 3 times volume swell when wet
- Seawater and cement water exposure
- High hydrostatic work including dams
Applications
- Expansion joints up to 1/2 in movement
- Isolation joints
- Construction and cold joints in thick walls
- Dams and other high-head structures

Frequently Asked Questions
When is Adeka Ultraseal KM-3030M a better pick than KBA-1510FP?
KM-3030M is the 30 x 30 mm mesh strip for thick walls (at least 1 ft), expansion joints, and higher head. Adeka Ultraseal KBA-1510FP is the low-pressure sponge for about 1 in cover and 25 ft head. If the wall is thin, KM-3030M is the wrong profile.
Can Adeka Ultraseal KM-3030M go in an expansion joint?
Yes. The OCM sheet lists expansion joints among the basic uses, with movement not exceeding 1/2 in. Isolation joints and thick cold joints are the other listed roles.
How much does Adeka Ultraseal KM-3030M swell?
About 3 times by volume (170% volume change on the press-sheet values). Stainless mesh in KM-3030M directs that swell so the strip does not wind along its length.
What wall or slab thickness is Adeka Ultraseal KM-3030M intended for?
The sheet says use KM-3030M only where wall or slab thickness equals one foot or greater. Thinner cover belongs on a lower-pressure profile such as KBA-1510FP.
Is Adeka Ultraseal KM-3030M used in isolation joints as well as cold joints?
Yes. Isolation joints are a listed use, along with expansion joints and construction or cold joints where concrete thickness exceeds 30 in.
Does Adeka Ultraseal KM-3030M hold up in seawater or cement water?
Yes. The OCM sheet lists seawater and cement water among the solutions KM-3030M can perform in, with no toxic substances or heavy metals.
