We manufacture Butyl Self Adhesive Tape and Flexible Water Stop for building waterproofing, surface sealing, and concrete joint protection. Our products cover different applications, from sealing roof joints, wall cracks, and pipe penetrations to protecting construction joints, expansion joints, and settlement joints against water penetration.
Each product serves a different purpose. Butyl Self Adhesive Tape creates a self-adhesive sealing layer on prepared surfaces, while Flexible Water Stop is embedded in concrete joints before pouring. Our range also covers waterproof sealing applications in RVs and boats.
1. Butyl Self Adhesive Tape
Our Butyl Self Adhesive Tape is made from butyl rubber, tackifiers, and anti-aging agents. Its self-adhesive, non-curing structure provides a sealing layer without requiring heating or additional adhesive during installation.
It is suitable for:
- Roof joints and waterproofing repairs
- Wall cracks and building joints
- Pipe penetrations
- Window and door sealing
- RV and boat sealing applications
The tape bonds to concrete, metal, glass, plastic, and existing waterproofing membranes. Installers simply remove the release film and apply it to the prepared surface. This cold-application method requires no specialized heating equipment or separate adhesive.
Our butyl tape is solvent-free and low-odor, with listed resistance to UV exposure, ozone, acids, and alkalis. The product information specifies an outdoor service life of more than 10 years.
2. Flexible Water Stop
Our Flexible Water Stop is designed for waterproofing joints within concrete structures. It is installed before concrete pouring and is suitable for construction joints, expansion joints, settlement joints, and pipe penetrations through concrete.
We offer three product types:
Elastic Rubber Water Stop
Made from rubber materials, this type accommodates joint movement and structural deformation. It is suitable for concrete joints requiring flexibility.
Water-Swelling Water Stop
This type expands upon contact with water, helping fill gaps in concrete joints and restrict water penetration.
Steel-Edge Water Stop
Its rubber and metal composite construction provides additional structural reinforcement for applications requiring a reinforced waterstop design.
These three structures address different concrete joint conditions and installation requirements. Rubber types have a listed service life of 10–20 years in underground or outdoor environments.
