FAQ
Questions clients ask us
Which shoring system is right for my basement?
It depends on depth, soil, groundwater and neighbouring structures. Diaphragm walls suit 2–3 level basements and high water tables; soil nailing and pile walls are economical for shallower cuts. Share your soil report and we'll advise.
Do you work outside Bengaluru?
Yes – we operate pan India and have delivered projects in Karnataka, Tamil Nadu and Gujarat.
Can you supply PT components only?
Yes. We manufacture and supply bonded and unbonded PT components – strands, wedges, anchor castings, ducts, pocket formers and end caps.
How quickly can you mobilise to site?
Mobilisation depends on equipment availability and site readiness. Contact us with your schedule and we'll confirm a plan.
