FRP tanks and MS FRP tanks
All-FRP tanks and mild steel tanks lined with FRP, for water, effluent and chemicals.
FRP waterproofing for terraces, tanks and wet areas
A seamless glass-fibre and resin lining laid on site over terraces, tanks and wet areas.
About FRP waterproofing
FRP waterproofing is a lining of glass-fibre mat and resin laid directly on the surface, on site. It cures into one continuous layer that bonds to the concrete, with no joints for water to find.
We use it where water sits or flows: terraces, water tanks and sumps, sunken bathroom slabs, planter boxes, swimming pools and concrete gutters. The lining is turned up the walls and coved at the corners, which is where leaks usually begin.
Applications for FRP waterproofing
-
Terraces and roofs
Exposed terraces that leak through cracks and at the parapet.
-
Water tanks and sumps
Concrete overhead tanks and underground sumps that seep.
-
Bathrooms
Sunken slabs and wet floors, lined before tiling.
-
Planters and podiums
Planter boxes and podium gardens over occupied floors.
-
Pools and water features
Swimming pools, fountains and ponds.
-
Gutters and drains
Concrete gutters and channels that leak at joints.
Customisation options
Everything we make is made to order. These are the choices you make with us before moulding starts.
- Layers
- One or more layers of mat, depending on foot traffic and exposure.
- Top coat colour
- Grey, white or a colour you choose. Light colours reflect heat on terraces.
- Anti-skid finish
- A textured top coat where people walk.
- Drinking water
- Tell us if a tank holds drinking water, so the materials are chosen for it.
- Details
- Outlets, pipes and drains are sealed into the lining.
How it's made and fitted
Made in our unit at Jakkur, Bangalore, and fitted by our own team.
-
Inspect
We look at the surface, existing leaks, slopes and drains.
-
Prepare
Loose material comes off, cracks are repaired, the surface is cleaned and dried, and coves are formed at wall junctions.
-
Prime
A primer is applied so the laminate bonds to the concrete.
-
Laminate
Glass-fibre mat is laid, wetted out with resin, rolled to remove air and lapped at every edge.
-
Top coat
A top coat seals the surface and protects it from sun and wear.
-
Test
Where practical, the area is water-tested before handover.
Typical jobs
The kind of work we're asked for most often.
- A terrace that leaked at the parapet every monsoon, lined with FRP and coved up the parapet.
- An underground sump with seepage through its walls, lined inside with FRP.
- Sunken bathroom slabs in a new villa, lined before screed and tiles.
Questions about FRP waterproofing
More answers on our FAQs page.
How is FRP waterproofing different from a waterproof coating?
Most coatings are thin films. An FRP lining is a reinforced laminate: glass-fibre mat set in resin, which makes it tough and continuous. Moving cracks and expansion joints still need their own detail, which we plan before starting.
Can FRP waterproofing be tiled over?
Yes. In bathrooms and sunken slabs the lining is usually covered with screed and tiles. On terraces it can be left exposed with a top coat, or covered.
Can you line a water tank that's in use?
The tank has to be emptied, cleaned and dried first, and the lining has to cure before it's filled again. We'll tell you how long it will be out of use.
Do we need to remove the old waterproofing?
Loose or failed layers have to come off so the FRP bonds to sound concrete. We'll tell you after the inspection.
