Every leak starts small. Left untreated, it undermines your walls, your structure, your investment. SealTech Prime applies the right system — once, properly — so the water stays outside.
Most property owners treat water damage as cosmetic — they repaint the damp wall, ignore the ceiling stain, seal the crack with silicon and move on. That's expensive thinking.
Water infiltration weakens concrete, corrodes rebar, breeds mould, and compromises structural integrity over years. The repair bill grows with every rain season you ignore it.

Moisture climbs walls silently, destroying finishes and air quality
Unremedied water pressure can crack load-bearing structures
Every year of delay multiplies the repair cost by 3–5×
From flat roofs baking in Nairobi's sun to basement walls under hydrostatic pressure — we have a system for it.
Flat slabs, terraces, and exposed concrete. We stop pooling, cracking, and UV degradation.
→Hydrostatic pressure control, tanking systems, and moisture barriers for below-grade spaces.
→Durable, food-safe linings for concrete tanks, masonry cisterns, and swimming pools.
→Perimeter drainage, waterproof membranes, and protective coatings for footings and walls.
→Polyurethane and epoxy injection systems for live cracks, joints, and active water ingress.
→Rising damp treatment, chemical DPC, and wall restoration that actually lasts.
→Most waterproofing failures happen because someone applied the wrong product to an undiagnosed problem. We don't do that.
We visit the property, identify every source of water ingress, and assess the surface conditions, drainage patterns, and structural risk before we quote anything.
Not every surface needs the same product. We select the membrane, injection system, or coating matched to your specific surface, exposure level, and water pressure.
We clean, repair, level, and prime every surface. Waterproofing fails at the prep stage more than anywhere else — we don't cut corners here.
We apply the system, check every joint, edge, and penetration point, then walk you through the result before leaving the site.
There are many waterproofing companies in Kenya. Most of them spray a coating, issue a receipt, and disappear before the next rain. We built our reputation differently.
Every job starts with a diagnosis. Every material is selected for the specific site condition. Every team member knows that our name is on that wall for years after we leave.
Meet the teamWe don't give blind prices. Every quote follows a real site visit and diagnosis.
One system doesn't fit all surfaces. We use the right product for each specific condition.
Our applicators have worked on rooftops, pools, basements, and foundations across Kenya.
We operate in Nairobi and across major towns in Kenya for large projects.
