You invested millions in a high-rise, mall, or commercial tower.
But now, water is leaking through the expansion joints, affecting interior finishes, damaging equipment, and threatening structural safety.
Unfortunately, many projects treat expansion joints as an afterthought â or trust generic sealants that donât hold up to Kenyaâs rains, heat, or movement.
Expansion joint waterproofing in Kenya is essential, not optional. And Phemat Solutions Ltd is your trusted specialist for it.
We offer flexible, chemical-resistant, and movement-accommodating joint sealing systems that protect your building envelope â even in the most demanding applications.
Whether itâs a CBD commercial tower, mall in Westlands, or office complex in Eldoret, we help you build confidently, protect tenants, and comply with code.
Expansion joints are designed to allow buildings to move without cracking. But when poorly sealed, they become highways for water ingress.
In Kenyaâs urban zones like Nairobi, buildings face:
Intense solar heat and heavy rainfall
High wind load and concrete expansion
Movement due to traffic vibrations and occupancy shifts
Multiple storeys requiring flexible but leak-proof connections
Without proper waterproofing, you risk:
Water leakage through floors and ceilings
Cracks at joints leading to façade or tile damage
HVAC or electrical duct corrosion
Safety risks in emergency staircases
Expensive downtime and post-handover repairs
Phematâs expansion joint waterproofing systems are built to adapt to movement â while locking out moisture, air, and debris.
We partner with Kenyaâs leading:

To provide innovative, affordable, and durable waterproofing and construction solutions that meet the needs of modern Kenya. one project at a time.
We exist to help individuals, businesses, and institutions protect their investments through reliable construction and waterproofing solutions. Our work isnât just about structures, itâs about building confidence, preserving value, and sustaining communities.
Every project begins with a site visit and ends with a watertight seal. Hereâs how we work:
We measure movement tolerance, substrate compatibility, and exposure type (roof, floor, wall, façade).
Debris and old sealants are removed. We grind, clean, and install bond breakers and backer rods where needed.
After application, joints are cured and tested for movement and leak protection. We document every step for engineers and clients.
We apply protective screeds, drainage mats, or geotextiles to ensure the membrane is not damaged during backfilling.
