Basement & Foundation Sealing.
The most expensive water problem in Nigerian construction - solved permanently.
Basement & Foundation Sealing, defined.
Basement and foundation waterproofing for new-build and existing structures. Positive-side and negative-side systems, crystalline slurries, polyurethane injection and active drainage management.
Basements are the most expensive water problem in Nigerian construction. The high water table in Lagos, the brackish ground conditions in coastal cities, and the construction-joint detailing that gets rushed in new builds - all of it conspires against a dry basement. The fix depends on what stage you catch it.
What we get called for.
- 01Visible water seepage at the base of basement walls
- 02Efflorescence on the inside face of basement walls
- 03Standing water in basement plant rooms or car parks
- 04Damp smell from below-grade rooms
Our approach.
- 01
Inspection to confirm whether the source is wall, slab, joint or penetration
- 02
Crystalline waterproofing on the positive face where access is possible
- 03
Polyurethane resin injection at construction joints and cracks
- 04
Negative-side coating system where excavation is not viable
- 05
Active drainage management where ground conditions demand it
Systems we are certified to apply.
- Sika
- Fosroc

FAQ.
- Can I get a basement dry that has been wet for years?
- Yes, in almost all cases. The longer you wait, the more invasive the fix - but the result is the same: a dry, usable basement.
- How long does basement waterproofing last?
- Crystalline systems are essentially permanent for the life of the structure. Injection repairs at joints are warranted for 10 years.
