Why is Water Tank Waterproofing Important for Your Home?

A water tank is one of the most essential parts of any home. It stores clean water for drinking, cooking, bathing, and other daily needs. But over time, water tanks often face leakage and seepage problems that can contaminate the water, damage the structure, and increase maintenance costs. This is where water tank waterproofing becomes important. A proper waterproofing solution protects your water supply, ensures safety, and increases the life of your tank.

In this blog, we’ll explore the benefits of water tank waterproofing, common causes of leakage, the best materials and methods, and why companies like Lakhwa Chemical Services are trusted for reliable solutions.

Benefits of Water Tank Waterproofing

1. Prevents contamination: Waterproofing keeps dust, algae, and external impurities from entering your water supply.

2. Extends tank life: By reducing cracks and seepage, your tank remains structurally sound for years.

3. Reduces maintenance costs: A waterproofed tank needs fewer repairs and saves you money in the long run.

4. Protects your home: Leaking tanks can cause dampness, mold, and even damage to nearby walls and ceilings.

5. Improves water quality: Waterproofing maintains a clean, safe water source for your family.

Common Causes of Water Tank Leakage

• Cracks due to aging: Concrete or plastic tanks weaken with time and develop hairline cracks.

• Poor construction: Using low-quality materials or improper curing during construction can lead to early leakage.

• Constant water pressure: Continuous storage and refilling put stress on the tank walls.

• Environmental factors: Weather changes, soil settlement, or seismic activity can cause structural damage.

• Lack of maintenance: Ignoring regular inspections can worsen small cracks into big leaks.

Best Waterproofing Materials for Water Tanks

The choice of material is critical for long-term results. Some commonly used waterproofing materials include:

• Cementitious waterproofing: Easy to apply and commonly used for both new and old tanks.

• Liquid waterproofing membranes: Flexible and durable, forming a seamless coating inside or outside the tank.

• Epoxy coatings: Provide a strong, chemical-resistant surface ideal for drinking water tanks.

• Polyurethane membranes: Highly elastic and effective for tanks exposed to extreme weather conditions.

At Lakhwa Chemical Services, experts analyze the type of tank and select the best waterproofing material to ensure safe, long-lasting results.

Step-by-Step Water Tank Waterproofing Process

1. Inspection: Checking the tank for cracks, seepage points, and weak areas.

2. Cleaning: Removing dirt, algae, and old coatings for a fresh surface.

3. Repairing: Filling cracks and repairing damaged areas with specialized materials.

4. Applying waterproofing material: Coating the internal or external surfaces with the chosen waterproofing solution.

5. Curing and testing: Allowing the material to set properly before filling the tank with water.

This process, when done professionally, ensures maximum protection and durability.

Difference Between Internal and External Tank Waterproofing

• Internal waterproofing: Focuses on coating the inner walls of the tank. It directly prevents water from seeping through cracks.

• External waterproofing: Applied to the outer surface of the tank, especially useful for underground tanks. It keeps moisture and groundwater from entering the tank.

Both methods are effective, but the choice depends on the tank type, location, and level of damage.

Waterproofing Solutions for Underground Water Tanks

Underground tanks are more vulnerable to seepage because of groundwater pressure and soil moisture. Common solutions include:

• Bituminous coatings for external surfaces

• Cementitious coatings inside the tank

• Liquid membranes for flexibility and long-lasting sealing

Professional service providers like Lakhwa Chemical Services specialize in handling underground tanks, ensuring both structural safety and water purity.

How to Maintain a Waterproofed Water Tank

• Inspect regularly: Check for cracks or signs of seepage every few months.

• Clean the tank: At least once or twice a year to avoid algae and sediment buildup.

• Avoid heavy loads: Do not place heavy objects on or near the tank that can cause structural stress.

• Get professional checks: Regular maintenance from specialists helps in early detection of problems.

Cost of Water Tank Waterproofing Services

The cost depends on:

• Size of the tank

• Location (overhead or underground)

• Choice of material

• Degree of damage

On average, waterproofing is a one-time investment that saves money in future repairs. Companies like Lakhwa Chemical Services provide affordable packages tailored to your tank type and budget.

Signs Your Water Tank Needs Waterproofing

• Damp patches around the tank

• Algae growth inside the tank

• Reduced water pressure due to leakage

• Stains or cracks on the outer walls

• Water contamination with odor or discoloration

If you notice these signs, it’s best to act quickly before the problem worsens.

DIY vs Professional Water Tank Waterproofing

• DIY waterproofing: Suitable only for very small cracks or temporary fixes. It usually involves sealants or coatings available in the market.

• Professional waterproofing: Provides long-term solutions, expert material selection, and guarantees durability.

When it comes to something as vital as your home’s water supply, relying on professionals like Lakhwa Chemical Services ensures safety, quality, and peace of mind.
