@MoWT_Uganda this is a tourism road heading to Bwindi (Rushaga) from Rubuguri town. This happened today, the road was already in poor Conditions. And then later we wonder why other countries are better than us when it comes to tourism. @assempebwa

@ApolloBuregyeya @bruno_akampa What a good reply technicality. Just hope the concrete dose not oxidize and steel is exposed and not treated because that's when the troubles will start

Are Kampala’s Flooded Basements About to Collapse? ======= For three days now, photos and videos of flooded basements in Kampala’s commercial buildings have been circulating online. People are asking a fair question: are these buildings about to collapse? As a structural engineer, my answer is simple but not short: Most properly designed buildings will not suddenly collapse just because their basements have been submerged for a few days. However, that does not mean there is no danger. The real risk is deeper and more long term. 1. This is not just rainwater. === In design textbooks, flood water is often treated as clean rain. Kampala’s reality is very different. Our city’s drains carry a mixture of storm water, sewage from on-site sanitation, oil and fuel from garages, detergents, industrial effluent, plastics, and decomposing organic waste. When this cocktail settles in the basement of a building, it brings with it: 1.1. Salts such as chlorides and sulphates 1.2. Acids from decaying waste 1.3. Oils and hydrocarbons 1.4. Fine clays and silts that keep structures damp Concrete itself can live under water for a very long time. We build offshore platforms, harbour structures and submerged tunnels with reinforced concrete. The problem is not simply “water.” It is what that water carries into the pores and cracks of the concrete and down to the steel reinforcement. 2. Immediate versus long term risk. === In the short term, three main structural concerns arise when a basement is flooded. First is lateral water pressure on basement walls. Water is heavy. One metre of water outside a wall is roughly one tonne per square metre pushing sideways. If water remains outside but is pumped out quickly inside, that unbalanced pressure can overstress a wall that was never designed for it. Second is uplift, or flotation. A basement is like a boat. Flood water and rising groundwater try to push the floor slab up. If the designer did not check “anti-floatation” properly, the slab can crack or lift, especially in areas built on former wetlands. Third is softening and erosion of soil. Moving flood water can wash away soil supporting foundations, just as scouring around a bridge pier can cause failure. Repeated flooding and poor drainage gradually undermine the ground that carries the building. If the building was well designed for these conditions, three days of standing water is unlikely to cause an instant collapse. If the basement was an afterthought on marginal land, with thin walls and poor detailing, the safety margin is much smaller. The bigger danger, however, is long term deterioration. 3. Corrosion, cracking and the wet–dry cycles. === Concrete protects steel reinforcement bars by keeping them in an alkaline environment. Chlorides and other aggressive ions in dirty flood water break down this protective layer and start corrosion (rusting) of the steel bars. As steel corrodes, the rust occupies more volume than the original metal. This expansion creates internal pressure, leading to cracking and spalling of the concrete cover. Over time, the steel bars that are supposed to carry the load become thinner and weaker. After the flood is pumped out, basements rarely dry uniformly. Parts remain damp, others dry quickly. The structure enters a cycle of wetting and drying. Ironically, corrosion is often most aggressive in these intermediate moisture conditions, not when concrete is fully soaked or fully dry. In a city where some basements flood several times a year, the pattern becomes predictable: flood, pump, crack, rust, repeat. The building may stand for years, but its remaining life quietly shrinks. 4. What should we do now? === For the current situation, three immediate actions are important. 4.1. Treat flooded basements as structural incidents, not just cleaning jobs. Pump water out in stages, not violently, to avoid creating large, unbalanced pressures on walls. 4.2 Require professional structural inspections. Owners should engage competent structural engineers to inspect walls, slabs, columns and foundation areas for new cracks, tilting, soil loss, exposed steel or spalling concrete. Findings should be documented and, where necessary, repairs done promptly. 4.3 Issue clear city-wide guidance. Kampala Capital City Authority (@KCCAUG ) and the National Building Review Board (@NBRBug ) should publish a simple post-flood inspection and repair protocol: what to check, when to restrict use, how to pump, and minimum repair standards for affected basements. In the medium term, planning authorities must ask a harder question: why do we keep approving deep basements in known flood plains and former wetlands, without insisting on strict durability and anti-floatation design? 5. Beyond the basements. === The real story is not that “all these buildings will collapse tomorrow.” Most will not. The real story is that floods have exposed our urban culture: our neglect of wetlands, our casual approach to drainage, our tolerance of construction in risky zones, and our weak enforcement of standards. Kampala’s flooded basements are a warning light on the dashboard. If we respond with science, enforcement and honest planning, we can still correct course. If we simply drain, mop and move on, the next generation will inherit a city with buildings whose decay started quietly, in three days of dirty water we chose to ignore.

🛑TRAFFIC ADVISORY: ROAD SECTION FAILURE ALONG KARUMA—KAMDINI–ROAD The Ministry of Works and Transport wishes to inform the general public of a road section failure along the Karuma—Kamdini section on Gulu Highway, approximately 1 km from the Karuma–Olwiyo/Pakwach junction from Kampala side/ [URA checkpoint]. Preliminary assessments attribute the failure to heavy rains, which caused the embankment failure. To ensure safety, the affected section has been hoarded off, and traffic is being managed on a single lane. Restoration works are being mobilized to reinstate the section as soon as possible. ⚠️ CAUTION: Motorists are advised to drive cautiously, reduce speed, and follow all traffic control instructions at the affected section. 🔄 DIVERSION: We advise all drivers of *heavy trucks and trailers* to divert at the Karuma–Pakwach junction [URA checkpoint] and proceed to Olwiyo Trading Centre, approximately 51 km from Karuma Junction, then turn right to connect through Anaka and continue to Gulu [approximately 62 km]. We regret the inconvenience caused and appreciate your cooperation as we undertake emergency interventions. Issued by; Ministry of Works and Transport 2nd November 2025

QUOTE: “No highway should be allowed to deteriorate…” — @GenWamala . Indeed, going forward, the In-House Construction Unit is being empowered to respond swiftly and effectively to the emerging needs of the road network. The team is currently mobilized at Namawojjolo, Namataba along Jinja highway addressing critical bottlenecks in preparation for sealing the section with asphalt. Similar interventions are scheduled for other sections along the corridor, including Lugazi, Kawolo, Najjembe, Mabira and Mbikko. 🙏🏾We urge road users to exercise caution along these work sections.

This is so bittersweet to watch. They can’t take away that feeling we all experienced. The best feeling in the world. I could not be prouder of our horse, the people I have brought together and the journey we are all on together. She’s our guineas winner, we couldn’t love her anymore
