Waterproofing Services in Sakumono — Complete 2026 Guide
Share
Fest Ghana Limited waterproofs roofs, parapets, bathrooms and water tanks in Sakumono and the lagoon-side estates near Tema. Properties here face a double load — coastal salt from the Atlantic and elevated humidity off the Sakumono lagoon — so the system has to be specified for both.
The Sakumono Condition
Sakumono lies within the 15km coastal salt band that runs along Ghana's shoreline. Add the lagoon immediately behind the estates and you get near-constant ambient moisture on top of salt exposure — a combination that shortens the realistic service life of an unprotected or poorly specified membrane faster than in inland towns such as Kumasi (roughly 1,400mm annual rainfall) or Koforidua (1,400-1,600mm).
We separate the two figures that Ghanaian waterproofing quotes often blur: the workmanship warranty (3 years — the period we return and fix it at our cost) and the design life (20 years — how long the membrane is engineered to keep performing). The manufacturer material warranty is also 3 years.
Realistic Service Life
| System | Design Life | Realistic Service Life in Sakumono |
|---|---|---|
| Standard 2-coat polyurethane | 20 years | 14-17 years |
| Coastal-rated fleece + chloride-blocking primer | 20 years | 17-20 years |
Where Fleece Reinforcement Earns Its Cost in Sakumono
Fleece-reinforced membrane doesn't extend the 20-year design life beyond what standard PU already offers — it bridges wider cracks (up to about 3mm versus roughly 0.3mm for standard film). In Sakumono that makes it worth specifying at parapet-to-roof junctions, gutter channels and pipe penetrations, where thermal movement and lagoon humidity concentrate stress. Applying it across an otherwise sound open roof field just doubles cost for no extra years.
Coverage — Two Coats, Not One
Our 5kg Polyurethane Coating (GHS 500) covers 20-40 m² per coat — 10-20 m² finished after the required two coats. The 10kg (GHS 1,000) covers 40-80 m² per coat, or 20-40 m² finished. Budget approximately 0.4 kg/m² across both coats for take-off — verified against a 370 m² job in Kpone Katamanso that used 150 kg (0.41 kg/m²).
