SECTIONAL WATER TANKS

Servicing & Maintenance

Does your tank have corrosion, erosion, or leaks? Drainmen Services provides expert solutions for all your sectional water tank needs.

It is crucial to engage a contracting company with technical experience and proper Occupational Health & Safety credentials when servicing industrial sectional tanks. These projects are beyond the scope of a standard plumber or general engineering company. Industry standards and SABS regulations exist for good reason, ensuring safety, compliance, and water quality.

Our Services Include:

• Water Tank Corrosion, Erosion & Leak Repair

• Water Tank Replacement

• Water Tank Refurbishment & Re-Lining

• Maintenance & Servicing

Potable water tanks can become easily contaminated, spreading disease. Drainmen Services has extensive experience with all types of sectional tanks, including:

We also specialize in servicing automated and non-automated valve applications, including:

• Knife-actuated valves

Let Drainmen Services audit your tank and provide the service your tank truly needs.

Benefits of Tank Re-Lining

Maintaining your tank in good condition is essential for clean, healthy water. Over time, tanks can suffer corrosion, erosion, and leaks. Drainmen Services provides expert tank re-line services for concrete, GRP, steel, and metal tanks.

While some may delay tank relining due to budget constraints, ignoring tank deterioration can lead to costly repairs and health risks. Drainmen Services offers a minimum 6-year guarantee against leaking, corrosion, and erosion.

Our Drainmen Polyurea System™ provides:

• High-quality refurbishment

• Easy maintenance with a smooth, tile-like finish

• Extended tank life and cleaner, safer water

Water Tank Replacement

Many engineers believe replacing steel tanks with GRP tanks is the ultimate solution. However, even new GRP tanks can develop micro-aquatic organism growth, osmosis, and leaks due to cavities, fine cracks, and chemical reactions within the laminate.

• Osmotic blistering and deterioration of the gel coat can create an environment for bacterial growth.

• Steel fastenings may corrode.

• Black spore fungi can proliferate in GRP tanks where water and air combine.

• Mastic between GRP panels can fail, causing leaks and water loss.

Most GRP tank manufacturers offer limited guarantees (6–12 months), which rarely cover long-term leaks or deterioration.

Water Tank Refurbishment – The Cost-Effective Solution

In most cases, repairing and refurbishing tanks is far more cost-effective than full replacement. Drainmen Polyurea System™ ensures:

• Surfaces are smooth, easy to clean, and compatible with Legionella treatment programs

• Long-lasting protection against corrosion, erosion, and microbial growth

• Minimized downtime and disruption to your business

• Environmental responsibility – avoiding disposal and replacement of large tanks
