Guardian Bituwrap Systems
Reliable bituminous corrosion protection for buried and submerged steel assets — proven performance against soil stress, moisture, and mechanical damage.
Reliable Protection for Buried Steel Assets
Guardian Bituwrap Systems provide cost-effective and durable corrosion protection for buried and submerged steel assets. The bituminous compound delivers high resistance to soil stress, moisture penetration, and mechanical damage from backfill and ground movement.
JST Group supplies and applies Guardian Bituwrap as a complete, turnkey corrosion protection system — covering product supply, surface preparation, professional application, and quality inspection from a single source.

Why Bituwrap Systems?
A proven underground corrosion protection solution — durable, economical, and reliably tested in field conditions worldwide.
High Soil Stress Resistance
Bituminous compound withstands soil movement, backfill loads, and ground shifting without cracking or disbonding.
Strong Steel Adhesion
Bonds directly to the steel substrate, creating a persistent moisture barrier that resists undercutting corrosion.
Proven Underground Performance
Decades of global field performance in buried pipeline applications across diverse soil conditions.
Economical Protection
A cost-effective solution for large-scale buried pipeline projects where coating area and material cost are critical factors.
Where Bituwrap Systems Are Applied
Buried Pipelines
Onshore oil, gas, and water pipelines requiring durable protection against soil corrosion and moisture ingress.
Tank Bottoms
External base surfaces of above-ground storage tanks in contact with soil or concrete foundations.
Underground Steel Structures
