Waterproofing in Sewri, Mumbai
Atlanta Waterproofing & Protective System provides waterproofing and building restoration across Sewri (F/South Ward, pincodes 400015, 400033). The locality records around 2,200 mm of rain annually and is dominated by dock and industrial stock and mill-era chawls in the 15-100 years range. We are roughly 45 minutes away.
What makes Sewri different
Dockside and mudflat exposure combines salt, industrial atmosphere and a high water table. Old industrial stock here frequently needs structural restoration before any waterproofing is meaningful.
The building stock here is principally dock and industrial stock, mill-era chawls, new towers on redeveloped land, mostly in the 15-100 years band. The failure patterns that follow from that are dockside salt and industrial exposure, mill-era structures at end of life, mudflat-adjacent high water table.
We work throughout the area, including around Sewri Fort, Sewri mudflats, Mumbai Trans Harbour Link landfall.
What we do in Sewri
- Terrace Waterproofing in Sewri
Terrace waterproofing is the application of a continuous water barrier across a roof slab, laid to a fall so rainwater drains rather than ponds.
- Basement Waterproofing in Sewri
Basement waterproofing protects a below-grade structure against groundwater under hydrostatic pressure.
- Bathroom Waterproofing in Sewri
Bathroom waterproofing seals the sunk slab and wet-area walls so water from daily use cannot reach the flat below.
- Toilet Waterproofing in Sewri
Toilet waterproofing seals the sunken slab, wall skirting and pipe penetrations of a WC area so water cannot migrate into the structure or the flat below.
- Brick Bat Coba Waterproofing in Sewri
Brick bat coba is the traditional Indian terrace system: broken brick pieces bedded in waterproofed cement mortar, laid to a fall and finished with china mosaic or IPS.
- China Mosaic Waterproofing in Sewri
China mosaic is a finish of broken glazed ceramic tile pieces set in waterproofed cement mortar over a terrace.
- APP Membrane Waterproofing in Sewri
APP membrane is an atactic-polypropylene-modified bitumen sheet, torch-applied to a primed substrate with lapped and sealed joints.
- SBS Membrane Waterproofing in Sewri
SBS membrane is a styrene-butadiene-styrene-modified bitumen sheet.
- HDPE Membrane Waterproofing in Sewri
HDPE membrane waterproofing uses a high-density polyethylene sheet, generally pre-applied below rafts and against retaining walls before concrete is poured.
- TPO Membrane Waterproofing in Sewri
TPO is a single-ply thermoplastic polyolefin membrane whose seams are hot-air welded rather than glued, producing a homogeneous joint as strong as the sheet.
- Polyurea Waterproofing in Sewri
Polyurea is a spray-applied, fast-setting elastomeric coating that gels within seconds and forms a seamless, high-elongation, highly abrasion-resistant membrane.
- PU Grouting in Sewri
PU grouting injects polyurethane resin under pressure into a leaking crack or joint.
- Injection Grouting in Sewri
Injection grouting forces a cementitious or epoxy grout under pressure into cracks, voids and honeycombed concrete to restore continuity and block water paths.
- Overhead Water Tank (OHWT) Waterproofing in Sewri
Overhead water tank waterproofing lines the internal faces of an elevated potable-water tank with a non-toxic, water-resistant system, and treats the external faces and base where leakage tracks into the structure below.
- Underground Water Tank (UGT) Waterproofing in Sewri
Underground tank waterproofing must resist water in both directions — the stored water pushing out, and groundwater pushing in.
- Swimming Pool Waterproofing in Sewri
Swimming pool waterproofing lines the pool shell so treated water cannot escape into the structure and so chemically treated water cannot attack the concrete.
- Podium Waterproofing in Sewri
Podium waterproofing protects a landscaped or trafficked deck sitting above occupied space — typically parking, a clubhouse or retail.
- Lift Pit Waterproofing in Sewri
Lift pit waterproofing seals the lowest point of a building's shaft, which sits below the water table in most of Mumbai and collects anything that runs down the shaft.
- External Plaster & Painting in Sewri
External plaster and painting is the building's first line of defence against driving rain.
- Building Restoration in Sewri
Building restoration is the structural rehabilitation of an ageing or distressed building — diagnosing why the concrete is failing, repairing it properly, and protecting it so it does not fail again.
Waterproofing in Sewri — questions we get asked
How quickly can you reach Sewri?
Our office is in Jogeshwari West, about 16 km from Sewri, and we normally allow around 45 minutes in off-peak traffic. We also work regularly in Parel, Wadala, Dadar, so a crew is often already in this part of the city.
Why do buildings in Sewri leak more than elsewhere?
Sewri records roughly 2,200 mm of rain a year, measured at the IMD Colaba observatory, island city. Combined with dock and industrial stock and mill-era chawls in the 15-100 years range, the recurring problems here are dockside salt and industrial exposure and mill-era structures at end of life. It is less that Sewri leaks more, and more that it leaks in a particular and fairly predictable way.
Which BMC ward is Sewri in, and does that matter?
Sewri falls under F/South Ward (F/South), covering pincodes 400015, 400033. It matters practically rather than technically: ward boundaries govern which office handles permissions, notices and any municipal correspondence a society may need during major repair work.
Does being close to the sea change what Sewri needs?
Substantially. Chloride from coastal air penetrates render and cover concrete and drives reinforcement corrosion far faster than inland. Two things follow: repair specifications must remove chloride-contaminated concrete rather than patch over it, and protective coatings should resist water ingress while still allowing the wall to dry outward. Sealing a salt-laden wall with an impermeable coating traps the problem inside.
Is Sewri on reclaimed land, and what does that mean for a basement?
Yes, substantially. Reclaimed ground retains water, continues to settle for decades, and puts a sustained hydrostatic head against below-grade structures. In practice that means a basement here needs a continuous wrapped barrier and water stops at every construction joint, plus working sump and dewatering provision. An internally applied coating on its own is being asked to hold back pressure from the wrong side.
