Precision, safety, and reliability — executed under live traffic conditions.
At Sri Vari Contractors, we specialize in advanced trenchless technology solutions for laying MS casing pipes across railway lines, national and state highways, and critical corridors. Our process begins with constructing a suitable driving pit, reinforced by RCC thrust walls and beds for maximum stability. Using modern equipment — cranes, jacks, compressors, welding machines, and jack hammers — we lower and weld pipes with precision to ensure durability and seamless performance, restoring sites to original condition upon completion.
