Concrete Water Tank Cleaning
Built to last, but not to be ignored
Concrete tanks are durable and common in underground installations, but mineral buildup and hairline cracking still develop over the years. We clean thoroughly and check the structure at the same time.
Concrete tanks, typically built underground as part of a property's original construction, are valued for their durability and structural strength. Over years of use, though, they develop mineral scaling on interior surfaces and can form hairline cracks that let groundwater seep in — issues that need a trained eye during cleaning, not just a scrub.
Types of Water Tanks We Clean
Common Water Tank Problems
Mineral scaling on interior walls
Years of water contact can leave a hard mineral deposit on concrete surfaces that a simple rinse won't remove.
Hairline cracks developing over time
Concrete can develop small cracks as it ages or shifts slightly, potentially letting groundwater into the tank.
Waterproof lining wear in lined tanks
Tanks with an internal waterproof coating can see that lining wear thin or peel over years of use.
Heavier sediment settling on rough concrete floors
Concrete's naturally textured surface holds onto sediment more than a smooth plastic or steel tank floor.
Health Risks of Dirty Water Tanks
Groundwater contamination through cracks
Cracks in concrete tank walls can let untreated groundwater seep into stored water, introducing contaminants.
Bacteria sheltering in scaling and texture
Mineral scale and concrete's natural texture both provide surfaces where bacteria can persist more easily than on smooth materials.
Lining degradation exposing water to raw concrete
If a waterproof lining fails, stored water contacts raw concrete directly, which can affect water chemistry over time.
Compounding risk in older, unchecked tanks
Concrete tanks built years ago without regular structural checks can accumulate multiple issues before any are noticed.
Signs Your Tank Needs Cleaning
Our Professional Cleaning Process
Structural crack assessment
We check for hairline cracks and any signs of groundwater intrusion before beginning the clean.
Mineral scale removal
Built-up mineral deposits are removed from interior walls using methods safe for concrete surfaces.
Sediment extraction from textured floors
Concrete's rougher floor texture gets extra attention to fully clear settled sediment.
Sanitization & lining check
The tank is sanitized and any internal waterproof lining is checked for wear as part of the same visit.
Inspection Before Cleaning
Concrete tank inspection focuses on cracking and lining condition, structural concerns specific to this material.
Checking for hairline cracks and groundwater intrusion signs
Assessing internal waterproof lining condition where present
Evaluating mineral scale buildup on interior surfaces
Sediment Removal Process
Concrete's naturally textured floor requires more thorough sediment extraction than smoother tank materials.
Extended extraction time for concrete's textured surface
Removal of mineral scale alongside standard sediment
Attention to corners and floor seams where debris compacts
Sanitization & Disinfection Process
Disinfection accounts for concrete's porous nature, which can hold onto contamination differently than sealed plastic or steel.
Disinfectant formulated for compatibility with concrete surfaces
Extended contact time given concrete's more porous texture
Full rinse to clear mineral and disinfectant residue
