Tzaneen, Limpopo
Tzaneen round concrete dam waterproofed with torch-on bitumen — 18 m diameter, approximately 255 m².
PROJECT DETAIL
A Tzaneen-area client required waterproofing on a round concrete dam used for water storage. Torch-on bitumen can be a practical option for selected concrete reservoirs, channels and water-retaining surfaces when surface preparation, overlaps and detailing are correctly handled.
PROJECT DETAIL
The Lowveld climate around Tzaneen brings high summer temperatures and strong UV, which makes surface preparation and membrane detailing important for long-term performance on exposed concrete.
The 18 m diameter round profile produced an estimated 255 m² waterproofing footprint. Continuous torch-on laps, corner detailing and penetration seals had to remain watertight under thermal movement on rigid concrete.
Damtech prepared the concrete surfaces and applied modified bitumen torch-on sheets in runs planned to maintain continuous laps across the round dam. Work was staged to suit site conditions suitable for torch application in the Lowveld.
OUTCOME
Approximately 255 m² of torch-on bitumen waterproofing was completed on the 18 m diameter concrete dam, supporting improved water retention on the structure.
18 m diameter round concrete dam — approximately 255 m² torch-on bitumen waterproofing.
Surface preparation and continuous membrane laps across rigid concrete.
Detailing at corners, outlets and penetrations completed to torch-on practice.
Improved retention for stored water in a Lowveld water storage application.
