Water Tank Waterproofing
Protect tank floors, walls, joints, and pipe penetrations against leakage and continuous hydrostatic pressure with Siegelt waterproofing solutions.
Application Overview
Overhead and underground water tanks require dependable waterproofing because their floors and walls remain under continuous water pressure. Cracks, construction joints, corners, and pipe penetrations can become direct leakage pathways.
Siegelt provides an integrated tank waterproofing system that protects the concrete shell and seals vulnerable joints and service penetrations. The system supports long-term water retention while helping protect the surrounding structure from moisture damage.
Product suitability should be confirmed according to the tank’s intended water use and project specifications.
Hydrostatic Pressure
Stored water creates constant hydrostatic pressure against floors and walls, exposing weaknesses in membranes, joints, and penetrations.
Common Waterproofing Challenges
Construction Joints
Cold joints between concrete pours can become leakage paths unless treated with swelling or flexible waterproofing components.
Concrete Cracks
Concrete shrinkage and settlement produce cracks that permit water loss, reinforcement corrosion, and deterioration of structural elements.
Pipe Penetrations
Inlet, outlet, overflow, and cleaning pipes interrupt tank walls, requiring precise seals around every service penetration point.Corner Junctions
Floor-to-wall and wall-to-wall junctions concentrate movement and pressure, making untreated corners especially vulnerable to recurring water leakage.
Water Compatibility
Unsuitable waterproofing materials may affect stored water quality, making tested system compatibility essential for intended tank usage.
Recommended Siegelt Waterproofing System
1
Seal Concrete Joints
Install Hydrophilic Swell Bar within construction joints before completing the concrete structure.
2
Protect Openings
Fit Pipe and Drain Collars around inlets, outlets, overflow pipes, and cleaning connections.
3
Apply the Membrane
Install Sealing Membrane across tank floors and walls to create continuous waterproof protection.
4
Inspect and Test
Check joints, corners, overlaps, and penetrations before conducting the recommended water-retention test.
Product Recommendations
Sealing Membrane
A flexible three-layer membrane designed to create a continuous waterproof barrier across water-retaining concrete surfaces.
Hydrophilic Swell Bar – TPE
A hydrophilic TPE profile that expands upon contact with water to seal pores, gaps, and irregularities within concrete joints.
Pipe and Drain Collars
Flexible collars that create secure seals around pipe penetrations passing through tank walls and floors.
