About TWAFrequently Asked.
Are you an authorized distributor — is the material genuine?
Yes. We buy directly from Fosroc, Sika, Pidilite (Dr. Fixit), MC-Bauchemie, STP and Soudal channels, supply factory-sealed, batch-coded packs and issue GST invoices that manufacturers honour for warranty support.
Do you deliver outside Ghaziabad?
Daily dispatches across Delhi NCR — Noida, Greater Noida, Delhi, Gurugram, Faridabad, Meerut — and pan-India for project quantities via transport.
Can you recommend the right product for my problem?
That’s our core value. Describe the structure and the symptom (seepage, joint failure, cracking) on WhatsApp with photos, and our technical team — led by a concrete technologist with 38+ years of practice — will specify the system, not just a product.
Do you also install what you sell?
Yes. We run trained applicator crews for waterproofing, expansion joint treatment, injection grouting and flooring — see our services.
