🚨 A Leaking Foundation Threatens Everything Above It

It doesn’t matter how beautiful the walls are or how modern the finishes look —
If the foundation leaks, the entire building is at risk.

Cracks in basements. Damp rising through floors. Mould creeping up interior walls.
These are not just common — they are costly, dangerous, and completely preventable.

At Phemat Solutions Ltd, we specialize in foundation waterproofing in Kenya, using deep-penetrating membranes, flexible joint systems, and high-performance drainage to keep water out — permanently.

We work with building contractors, engineers, and housing projects across Nairobi, Kisumu, Eldoret, Machakos, and beyond, to protect structures from the ground up.

💧 Why Foundation Waterproofing in Kenya Is Critical

Kenya’s soil and weather conditions make foundation sealing a non-negotiable part of construction.

  • Heavy rains in Kisumu or Eldoret cause groundwater pressure

  • Expansive black cotton soil in Nairobi and Machakos increases cracking

  • Poor drainage and faulty basements lead to rising damp

  • Inadequate concrete compaction allows seepage

Without professional foundation waterproofing, your building is vulnerable to:

  • Structural damage from water ingress

  • Floor bubbling and internal wall cracks

  • Steel reinforcement corrosion

  • Black mould and health risks

  • Reduced resale value and costly litigation

That’s why the most forward-thinking engineers and developers waterproof at the foundation level — not after problems start.

James N. Project Manager, Affordable Housing Build

We had a serious issue with rising damp in our Machakos housing site. Phemat waterproofed 48 units' foundations before slab casting. Perfect result.

Eng. Atieno Structural Engineer

Our school project in Kisumu had a high water table. Phemat used membrane plus drainage board. It's dry, clean, and solid — even after 2 rainy seasons.

Peter K. Developer

We were building in Kitengela black cotton soil. Phemat sealed our retaining walls and basement with zero leakage. Very technical and very professional.

❓ Frequently Asked Questions (FAQs)

1. When should foundation waterproofing be done?

Ideally during construction — before backfilling. This allows full access to foundation walls, footings, and joint areas for proper membrane application.

2. Can you waterproof an already constructed foundation?

Yes. We offer retrofit waterproofing using exterior excavation, injection sealing, or interior membranes — depending on the structure and severity.

3. How long does foundation waterproofing last?

With proper application, high-quality membranes can last 25–50 years. We also offer warranties and maintenance plans for peace of mind.

4. Is waterproofing required by law in Kenya?

Yes. Both NCA and county bylaws recommend or require damp-proofing and substructure sealing — especially for housing, commercial, and school projects.

5. Do you work with construction companies and project engineers?

Absolutely. We’re fully equipped to partner with contractors, civil engineers, architects, and quantity surveyors — and can scale for estate and institutional projects.
