Ambattur is two places in one: one of Chennai's oldest industrial estates, and the residential neighbourhoods that grew up around it in Padi, Korattur, Avadi and Ambattur itself. WATREX works on both, but most of the calls from here are about leaking factory and warehouse roofs.
Factory roofs: fix the leak, keep production running
Most units in Ambattur Industrial Estate work under metal or cement sheet roofs. These rarely leak through the sheet itself. They leak at the screws, where years of heating and cooling have hardened the washers, at the overlaps between sheets, at ridge caps, and at gutters sealed with ordinary silicone that peeled off long ago. A drip over a machine or a stack of finished goods is expensive, so the repair has to happen without shutting the floor.
We survey the roof with safety lines, map every leak and agree a schedule with you so work over sensitive areas happens between shifts. Fasteners are replaced or capped, laps and ridges are sealed with bitumen tape, rusted patches are treated, and gutters are cleaned and lined. Sheets are replaced only where rust has gone right through. See metal sheet and bitumen membrane waterproofing.
For flat concrete roofs on office blocks and newer sheds, we lay a torch-applied APP bitumen membrane.
Homes in Ambattur, Padi and Avadi
The residential side has the usual Chennai problems: ageing terraces, bathrooms leaking into the floor below, and sumps taking in water during the monsoon, particularly in the lower-lying streets near the lakes. See terrace waterproofing and sump waterproofing.
What we fix most in Ambattur

Planning a visit
Ambattur is across the city from our office on OMR at Kazhipattur. For factory roofs we plan the survey with you in advance. For homes, message us a few days ahead and we will fit you into a day we are working in the area.
Neighbourhoods we cover
Ambattur, Ambattur Industrial Estate, Padi, Korattur, Avadi and Pattaravakkam, plus Anna Nagar to the east and Porur to the south.
Common questions
Which part of a factory roof usually fails first?
The screws and the overlaps. Heat hardens the rubber washers under each screw, and daily expansion opens the laps between sheets, years before the sheets themselves wear through.
Can you survey several units in Ambattur Industrial Estate on one visit?
Yes. If neighbouring units need work, we can survey them on the same day and give each owner a separate, itemised quote.
Do you cover Avadi, Padi and Korattur?
Yes, for both industrial and residential buildings.
