💧 Moisture Is Silent — But Cementitious Waterproofing Stops It Cold

You’ve seen it before. Damp spots on basement walls. Cracks leaking water. Mould creeping across concrete floors.
Moisture doesn’t shout — but it slowly eats away your structure from the inside out.

That’s why cementitious waterproofing in Kenya is the trusted solution for builders and contractors who want long-lasting, deep-penetrating protection for concrete surfaces.

At Phemat Solutions Ltd, we specialize in applying high-performance cementitious systems that bond permanently with concrete to seal out water, resist pressure, and stop damage before it starts.

Whether you’re building a tank, sealing a basement, or protecting a bathroom slab, we’re here to make sure water never becomes your worst enemy.

🔍 What Is Cementitious Waterproofing?

Cementitious waterproofing is a two-component system that blends cement with advanced polymers to form a rigid or flexible coating that:

  • Bonds to concrete and masonry surfaces

  • Resists hydrostatic pressure from inside or outside

  • Blocks water penetration and capillary movement

  • Is ideal for interior or protected exterior surfaces

It is widely used for:

  • Water tanks (internal coating)

  • Underground basements

  • Lift pits and wet areas

  • Retaining walls and sunken slabs

  • Balconies and bathrooms

  • Culverts, tunnels, and concrete bridges

If it’s concrete and needs to be watertight, cementitious waterproofing is the answer.

📞 Don’t Let Moisture Weaken Your Concrete. Act Early.

Concrete is strong — but not waterproof.
Without protection, it absorbs water, corrodes reinforcement, and shortens your structure’s lifespan.

Cementitious waterproofing is the most cost-effective way to seal concrete from within — and keep moisture out for decades.

Let’s stop water before it starts damage. Permanently.

Eng. Mwangi Project Manager, Real Estate Developer

We were struggling with seepage in 3 underground tanks at our Thika site. Phemat sealed them with cementitious coating, and we’ve had zero water loss since. They’re real professionals.

Faith K. Facilities Manager, Kisumu

Phemat did cementitious waterproofing in our hotel’s wet rooms and balconies. Two years later, still leak-free. They worked neatly and even helped us solve slope issues.

Peter O. Civil Contractor

They sealed our elevator pit and pump room in Eldoret using a two-component membrane. Job was on schedule, and they gave us a 5-year guarantee. Great workmanship.

❓ Frequently Asked Questions (FAQs)

1. What surfaces are ideal for cementitious waterproofing?

Cementitious systems are perfect for concrete walls, slabs, tanks, pools, lift shafts, and wet rooms — basically any cement-based surface needing waterproofing.

2. Is cementitious waterproofing suitable for exposed outdoor areas?

It works well in protected outdoor areas. For exposed spaces like terraces or rooftops, we combine cementitious base with top UV-resistant finishes or screed overlays.

3. How long does cementitious waterproofing last?

With correct application and surface prep, it can last 15–30 years. It's a rigid but long-lasting solution for low-movement surfaces.

4. Is this method safe for drinking water tanks?

Yes — we use KEBS and potable-grade membranes that are non-toxic and certified safe for internal tank use, including drinking and food-grade water.

5. Can I apply cementitious waterproofing myself?

Not recommended. Mixing ratios, curing time, and substrate prep are critical. For lasting results, always hire a trained waterproofing professional.

🧾 External Compliance Reference

All waterproofing solutions meet:

  • KEBS – Waterproofing Product Standards

  • ASTM C 836 / EN 1504-2 – Performance specs for cementitious coatings on concrete
  • National Construction Authority (NCA) compliance for structural works and sealing procedures

We use certified, non-toxic, UV-resistant materials safe for homes, institutions, and large developments.
