Void Forming Spiral Tubes

BWC is a leading manufacturer of Void Forming Spiral Tubes and Bridges Void Former.

Void Forming Spiral Tubes were specially designed and developed by BWC in collaboration with AECOM and Larsen & Toubro for NHAI and IRC. Specific machineries were designed and developed by BWC to manufacture Void Forming Spiral Tubes.​

The “specially patented” Void Forming Spiral Tubes manufactured by BWC are very rigid but yet light weight. They easily withstand existing forces during the pouring of concrete and are fully leak proof, which prevents water from the concrete to enter into the tubes. The light weight of our Void Forming Spiral Tubes makes them easier to handle during the installation process.
