Waterproofing Services in Obuasi, Ashanti Region 2026
Share
Fest Ghana Limited installs polyurethane roof, wall, and water tank waterproofing in Obuasi, Ashanti Region, at GHS 80-130 per square metre for a standard 2-coat system. The membrane carries a 3-year workmanship warranty, a 3-year manufacturer material warranty, and a 20-year engineered design life.
Obuasi's Building Stock and Its Waterproofing Problems
Obuasi is a working mining town, and its building stock reflects that: dense residential compounds, commercial strips along the main roads, workshops, and warehouses supporting the AngloGold Ashanti operations and the wider local economy. Ashanti Region rainfall runs comparable to Kumasi's roughly 1,400mm a year, concentrated in two rainy seasons, and the daily thermal swing on an exposed concrete roof — hot sun through the afternoon, sudden rain, a 20°C swing in surface temperature — is what eventually cracks an unprotected slab.
What We Waterproof in Obuasi
Our Obuasi work covers residential flat roofs and compound homes, commercial rooftops along the Kumasi road corridor, warehouse and workshop roofs, and water tanks and sumps for both households and small businesses. We also get called for box-gutter repair on older metal-roofed buildings, where corrosion at the gutter seams is usually the actual point of failure, not the roof sheets themselves.
Pricing in Obuasi
| System | Installed Rate |
|---|---|
| 2-coat polyurethane (open roof field) | GHS 80-130/m² |
| Fleece-reinforced (parapets, gutters, cracks) | GHS 180-280/m² |
| Torch-on membrane | GHS 150-220/m² |
Material Quantities: Getting the Order Right
Coverage is always quoted per coat, and every job needs two coats — that's where most Obuasi quotes go wrong. Our 5kg Polyurethane Coating (GHS 500) covers 20-40 m² per coat, or 10-20 m² finished after both coats. The 10kg pail (GHS 1,000) covers 40-80 m² per coat, or 20-40 m² finished. For take-off purposes, use roughly 0.4 kg per square metre across two coats — verified against a documented 370 m² job at Kpone Katamanso that used 150 kg (0.41 kg/m²). Ask any contractor quoting your Obuasi roof how many kilograms their price actually includes.
Warranty and Design Life
The warranty is the period we return and fix it at our cost; the design life is how long the membrane is engineered to keep performing. Fest Ghana's workmanship and material warranties are each 3 years, and the system carries a 20-year design life. Inland towns like Obuasi, with no coastal salt exposure, typically see 18-20 years of real service life when gutters are kept clear and parapet joints are checked each year.
