Waterproofing & Seepage Solutions
A drier space starts with understanding the water.
We investigate leaks and dampness, identify likely entry paths and plan treatments suited to the source and the affected surfaces.
Sikkim's heavy monsoon and hillside groundwater make seepage one of the most common problems in local buildings. Left untreated, water does far more than spoil paint: it reaches the steel inside the concrete, which rusts, expands and cracks the structure from within.
We treat waterproofing as an engineering problem. First we find where the water is coming from and how it travels. Then we select a treatment suited to that location, whether a roof, a retaining wall, a bathroom or a basement, and repair any damage it has already caused.
Common problems we fix
- Roof and terrace leaks during the monsoon
- Damp patches, peeling paint and efflorescence on walls
- Seepage through retaining walls and basement walls on hill slopes
- Leaking bathrooms, water tanks and sunken slabs
- Rust stains or spalling concrete caused by long-term water ingress
What the work can include
Leak investigation
Tracing the source and path of water, including moisture readings and checks on drainage, joints and cracks.
Roof and terrace waterproofing
Membrane, coating or cementitious systems chosen for exposure, slope and foot traffic.
Crack injection and sealing
Epoxy or polyurethane injection to seal active leaks and structural cracks.
Basement and retaining wall treatment
Negative and positive side waterproofing, along with drainage behind walls to relieve water pressure.
Corrosion repair
Removing damaged concrete, treating corroded reinforcement and restoring the section with repair mortars.
Frequently asked questions
Why does seepage keep coming back after repair?
Usually because the visible damp patch was treated, not the source. Water can travel a long way inside walls and slabs before it appears. We investigate the path before choosing a treatment.
Is seepage a structural problem?
It can become one. Long-term moisture corrodes reinforcement, which weakens beams, slabs and columns. Treating seepage early is far cheaper than repairing structural damage later.
When is the best time to waterproof?
Ideally in the dry season, before the monsoon. Surfaces need to be dry for most systems to bond properly. Investigation, however, is often easiest while leaks are active.
