FAQ

Q: What is an internal pipe seal?
A: It's a trenchless, mechanical sealing system installed inside a pipeline to stop leaks, joint infiltration, and groundwater intrusion—without excavation.

Q: What materials are used?
A: internal seals are made of high-grade EPDM rubber and stainless steel expansion bands, ensuring long-term durability and corrosion resistance.

Q: What pipe types are compatible?
A: The seal works with concrete, PVC, HDPE, ductile iron, vitrified clay, and steel pipes. Custom sizing is available for round, oval, or offset joints.

Q:  Is excavation required?
A: No. The seal is installed from inside the pipe using a mechanical expansion tool. No adhesives, primers, or digging required.

Q: What sizes are available?
A: We offers seals for pipe diameters ranging from 150mm to 4000mm. Custom dimensions can be manufactured upon request.

Q: How long does installation take?
A: Most seals can be installed in under 30 minutes by a two-person crew. No curing time is needed.

Q: Is the seal watertight?
A: Yes. The compression seal resists external pressure, preventing groundwater infiltration and increasing system efficiency.

Q: Can it handle pipe movement or deformation?
A: Yes. The rubber sleeve is flexible and conforms to out-of-round shapes, joint offsets, and diameter variations.

Q: What is the expected service life?
A: Our internal pipe seals are designed for 20+ years of service, backed by industry benchmarks and material standards.

Q: Where is it used?
A: Ideal for sewer systems, stormwater drains, drinking water pipelines, gas lines, and industrial infrastructure.
