We are a Kenyan waterproofing company that specialises in diagnosing and permanently solving water infiltration problems in residential, commercial, and industrial buildings.
SealTech Prime Limited was founded with a simple frustration: too many property owners in Kenya were spending money on waterproofing that failed within months — because it was applied over undiagnosed problems, using the wrong product, by teams that didn't understand surface preparation.
We set out to build a company where every job starts with a real inspection, every product is matched to the specific problem, and every team member is trained to the standard the job requires.
The result: we've completed over 200 projects across Nairobi and major Kenyan towns, serving homeowners, property developers, construction contractors, and government institutions.
We don't quote blind and we don't guess. Every engagement starts with a trained eye on the actual problem before we recommend anything.
There's no universal waterproofing solution. We match the system to the surface, the water pressure, the exposure, and the budget — in that order.
We stand behind our work. Our reputation in Kenya is built on jobs that hold up through multiple rain seasons, not just the first month.
Most waterproofing failures begin at the prep stage. We take it seriously — clean, repair, prime — before any product goes on.
If we can't fix it permanently, we'll say so. We'd rather lose a job than promise something we can't deliver.
Our systems are selected for local climate, construction methods, and material availability. Not a generic import from another market.
SealTech Prime works with a wide range of clients — each with different needs, timelines, and scales of work.
Roof leaks, damp walls, rising damp, basement moisture — we handle residential water problems of all sizes.
New construction waterproofing and retrofit systems for investment properties, apartments, and commercial buildings.
On-site waterproofing subcontracting for roofs, foundations, basements, and wet areas during active construction.
Waterproofing for schools, hospitals, offices, and public infrastructure across Kenya.
We are based in Nairobi and operate across the greater Nairobi metropolitan area as well as major towns across Kenya for large-scale or institutional projects.
