Our services

Every waterproofing problem has a solution.

We handle roofs, basements, pools, tanks, foundations, cracks, and damp walls — with the right product for each specific condition.

01 — Roof Waterproofing

Stop the leak. Protect the slab.

Flat concrete roofs in Kenya take constant punishment — intense sun, heavy rain, and thermal expansion. Without proper waterproofing, they crack, pool water, and eventually allow seepage that destroys your ceilings, walls, and everything beneath.

We apply systems ranging from liquid-applied membranes to torch-on bituminous sheets, depending on your roof's condition, slope, and drainage layout.

  • Flat roof and terrace waterproofing
  • Concrete slab leak diagnosis and repair
  • UV-resistant protective topcoats
  • Gutter and downpipe integration
  • Roof joint and edge treatment
  • Emergency roof leak sealing

02 — Basement Waterproofing

What's underground stays dry.

Underground spaces face hydrostatic water pressure constantly. Water pushes through concrete pores, joints, and cracks — often without any visible external sign until the interior is soaked.

We use tanking systems, cavity drain membranes, and crystalline waterproofing compounds to create a permanent barrier, regardless of water table depth.

  • Hydrostatic pressure control
  • Tanking systems for underground rooms
  • Retaining wall waterproofing
  • Basement floor slab treatment
  • Drainage cell and sump pump integration
  • Cavity drain membrane installation

03 — Water Tanks & Swimming Pools

Structures built to hold water. Systems built to keep it there.

Water tanks and swimming pools operate under constant pressure from the inside. The waterproofing system must be flexible, durable, and where relevant, food-safe for potable water tanks.

We use specialist pool coatings and cementitious waterproofing systems rated for permanent immersion.

  • Concrete water tank lining (food-safe)
  • Masonry cistern waterproofing
  • Swimming pool full waterproofing system
  • Pool crack injection and joint repair
  • Tile prep waterproofing layer
  • Rooftop tank waterproofing

04 — Foundation Waterproofing

Protect from the ground up. Literally.

Foundations are the most critical point of water entry — and the hardest to fix once construction is complete. We provide waterproofing during construction and post-construction foundation protection for existing buildings.

  • Perimeter foundation membrane application
  • Below-slab moisture barrier installation
  • French drain and perimeter drainage design
  • Retaining wall exterior waterproofing
  • Construction-phase waterproofing consultation

05 — Crack Injection & Leak Repair

Active leaks. Permanent fixes.

Not every water problem requires full waterproofing. Sometimes the entry point is specific — a crack in a retaining wall, a failed expansion joint, a pipe penetration. We diagnose the exact source and apply the right injection system for it.

  • Polyurethane foam injection for active leaks
  • Epoxy injection for structural crack repair
  • Expansion joint reseal and waterproofing
  • Concrete joint treatment
  • Pipe penetration waterproofing
  • Cold joint treatment

06 — Damp Proofing

Rising damp doesn't get better with time.

Damp walls are one of the most misdiagnosed problems in Kenyan construction. Most people repaint and hope for the best. The moisture returns within months because the source — rising capillary action or failed DPC — was never addressed.

We identify the cause, install a chemical damp-proof course where needed, and restore the wall surface to a condition that actually holds its finish.

  • Rising damp diagnosis and treatment
  • Chemical damp-proof course injection
  • Wall salt treatment and replastering
  • Penetrating damp remediation
  • Interior wall moisture barrier application
  • Mould-resistant finishing system

Common questions

What people ask before they call

How long does waterproofing last?

+

Properly applied waterproofing with quality materials typically lasts 10–20 years depending on the product type, surface condition, and exposure. Liquid membranes on rooftops may need recoating every 5–8 years in high-UV areas. We'll tell you what to expect for your specific system before we start.

Can you waterproof over existing finishes?

+

Sometimes yes, sometimes no — it depends on the condition of the existing surface. Waterproofing over a failing finish usually fails itself. We always inspect and often prepare surfaces first (remove loose material, clean, prime) before applying any new system.

How quickly can you respond to an emergency leak?

+

For urgent situations in Nairobi, we aim to be on site within 24–48 hours. Call us directly on +254 726 460 976 for emergencies — we'll assess what can be done immediately and what needs a longer-term fix.

Do you provide a warranty?

+

Yes. We provide warranties on our workmanship. The warranty period varies by service type and is discussed before project commencement. Most manufacturer warranties on materials we use are also passed on to clients where applicable.

Do I need to vacate my property during waterproofing?

+

Usually not. Most waterproofing work is on exterior surfaces — rooftops, outside walls, basements. Interior damp proofing and pool work may require temporary access restrictions, but rarely full evacuation. We'll advise on this during the inspection.

Not sure which service you need?

That's exactly what the free inspection is for. We'll come out, look at the problem, and give you a clear recommendation — no obligation.
