Why leaks are hard to find
Water travels. It can enter at a terrace crack, run along a beam or a pipe and appear as a stain two rooms away. That is why many repairs fail: they treat the place where the damage shows instead of the place where the water gets in.
Our leak detection in Hyderabad combines careful inspection, moisture checks and controlled water tests on the terrace, bathroom or pipes to isolate the source. Once it is found, injection grouting seals the crack, joint or void from inside the concrete, which also works on active, wet leaks where coatings cannot bond.
When you need leak detection
- Repeated repairs haven't workedThe leak returned after re-painting, re-grouting or a new coating.
- Stain far from any water sourceDamp appearing in a room with no bathroom or terrace directly above.
- Leak only after heavy rainPoints to a crack or joint in the roof, wall or parapet that only takes water in heavy rain.
- Leak even in dry weatherSuggests a plumbing pipe, tank or bathroom rather than rain.
- Active water through concreteWater dripping or flowing through a slab, wall or joint.
- Cracks in beams or slabsCracks that stay wet need sealing, and structural cracks need bonding.
How we find and seal leaks
Inspection & history
We ask when and where the leak appears and inspect the damp area and everything above and around it.
Moisture mapping & water tests
Moisture checks and controlled flood tests on terraces, bathrooms and pipes isolate the exact source.
Drill injection ports
Holes are drilled at an angle to meet the crack or joint inside the concrete, and packers are fitted.
Inject PU or epoxy grout
PU grout expands to seal water paths; epoxy grout bonds structural cracks. Injected under pressure until the path is filled.
Seal & verify
Ports are removed and patched, and the area is re-tested to confirm the leak has stopped.
Injection grouting systems
PU injection grouting
Expanding polyurethane that reacts with water to seal active and wet leaks in cracks and joints.
Epoxy injection
Low-viscosity epoxy that bonds and strengthens structural cracks in beams, columns and slabs.
Cementitious grouting
Fills larger voids and honeycombed concrete behind the surface.
Construction joint sealing
Sealing the horizontal and vertical joints where concrete pours meet, a common basement leak path.

Leak Detection & Injection Grouting: frequently asked questions
It is a method of sealing a leak from inside the concrete. Small holes are drilled to meet the crack or joint, and a grout is pumped in under pressure to fill the path the water was taking.
Yes. PU grout reacts with water, so it seals leaks that are wet or even running, which is why it is used in basements, lift pits and during the monsoon.
We start with non-destructive checks and water tests. Injection only needs small drilled holes, which are patched afterwards.
The free inspection includes a visual check and our assessment of the likely source. Extended water testing for complex leaks is explained and quoted before we start.
