For a building to remain reliable for many years, all below-ground elements must be protected against water and moisture. Foundations and retaining walls can be exposed to soil moisture, surface water and groundwater, making foundation waterproofing one of the most critical stages of construction.
Water ingress can contribute to reinforcement corrosion, concrete deterioration, damp basements and indoor moisture problems. Since foundations are difficult to access after construction, repairs can also be expensive.
The substrate should be clean, sound and as even as possible. Loose particles and sharp projections must be removed.
Where required, a suitable primer is applied to improve compatibility and adhesion.
Bituminous membranes should be installed according to the technical data sheet and project details, with special attention to overlaps and wall-floor junctions.
Pipe penetrations, expansion joints and corners require careful detailing to maintain continuity.
After installation, the membrane should be protected from mechanical damage during backfilling.
Ground conditions, groundwater level, building type, mechanical loads, climate and technical specifications should all be considered.
İzopak offers bituminous membrane solutions for different project requirements. For contractors, applicators and project stakeholders such as Topak İnşaat, correct membrane selection supports investment security and long-term building performance.
Foundation waterproofing should be correctly designed and executed during construction. Quality materials, proper detailing and professional installation work together to provide durable protection.
