Waterproofing Remediation Works – Resting Balcony

Project Overview & Site Background

In early 2026, a homeowner in Ajigo, Bondo, reached out to Phemat Solutions Ltd after persistent water ingress began damaging the resting balcony of their residence. The balcony, approximately 98sqm, had been tiled and was used regularly for relaxation, but over time, water started seeping through the floor and around the glass sections, causing dampness and threatening the structural integrity of the slab. The homeowner had previously engaged local handymen for patch repairs, but these failed to address the root causes. Seeking a permanent solution, they contacted Phemat Solutions, recognized as leading waterproofing services in Kenya for residential and commercial properties.

Initial Structural Diagnostics

Our technical team conducted a thorough site assessment using digital moisture meters and thermal imaging. The diagnostics revealed multiple issues: the existing floor tiles were debonded in several areas, the screed had inadequate falls leading to ponding, floor traps were clogged and poorly integrated, and the joints around the glass sections were deteriorated. Moisture readings indicated saturation levels above 85% in the substrate, confirming active water migration. Cracks and voids were also noted at wall-to-floor junctions. It was clear that localized repairs would not suffice; a full remediation was necessary.

Critical Site Challenges

The project presented several challenges. The balcony was on the first floor, limiting access for heavy equipment. The rainy season was approaching, requiring swift execution to avoid weather delays. Additionally, the homeowner remained in residence, so we had to minimize noise and dust. The glass balustrade, approximately 35 linear metres, required delicate handling to avoid breakage during joint sealing. Drainage realignment needed precise grading to ensure water flows to the six floor traps without ponding.

Engineered Technical Solution

Phemat Solutions implemented a multi-stage remediation plan tailored to the site conditions. The process began with the careful removal of existing tiles and adhesive using manual chisels and grinders to expose the substrate. The surface was then mechanically prepared by scarifying and shot-blasting to remove laitance and contaminants, followed by thorough cleaning. Cracks and voids were repaired using a rapid-setting repair mortar. Wall-to-floor junctions were detailed with angle fillets to eliminate sharp corners. The drainage pipework was removed, realigned to correct falls, and reinstated. Six new floor traps were installed and integrated with the waterproofing system. Joints around the glass sections were cleaned and sealed with a polyurethane sealant. A new screed was applied with precise falls toward the drains. The substrate was primed, and a flexible cement-based waterproofing membrane was applied in two coats, with fiberglass reinforcement mesh embedded between coats for added tensile strength. All penetrations and junctions received additional membrane reinforcement. After curing, the final tile finish was reinstated.

At Phemat Solutions, we do not just stop leaks; we engineer waterproofing systems that last. Every project is backed by our rigorous quality control and a 10-year limited warranty, giving our clients complete peace of mind.

Quality Verification & 24-Hour Flood Testing

Upon completion of the waterproofing membrane, we conducted a 24-hour ponding test. The balcony area was flooded to a depth of 25mm and monitored for any signs of leakage. Moisture readings were taken at regular intervals, and after 24 hours, no drop in water level or increase in substrate moisture was detected. The test confirmed the integrity of the system. We also performed a visual inspection of all details, ensuring continuous coverage and proper sealing. The homeowner was invited to witness the test and expressed satisfaction with the thoroughness.

Final Results & Client Impact

The waterproofing remediation was completed within three days, on schedule and within budget. The balcony now features a fully watertight system with proper drainage, eliminating the previous dampness and protecting the structure from future water damage. The homeowner can once again enjoy the space without worry.
