Protection for Structures That Hold Water

Water tanks are constantly exposed to moisture and water pressure. Cracks, joints, and surface weaknesses can create pathways for leakage and gradually affect the surrounding structure. Goodwill provides water tank waterproofing solutions with a focus on surface condition, proper preparation, and careful application.

Leakage Protection

Helping prevent water from escaping through vulnerable tank surfaces.

Crack & Joint Treatment

Sealing suitable cracks, joints and other potential leakage points.

Moisture Protection

Reducing water exposure to the surrounding structure and surfaces.

Tank Surface Protection

Suitable Environments

Residential pools, hotel pools, resort pools and commercial swimming facilities face continuous water exposure. Our swimming pool waterproofing systems are selected based on pool construction, surface condition and leakage points, with solutions suitable for projects in Coimbatore.

Complete Waterproofing Solutions

Roof
Waterproofing

Roof waterproofing is one of the most challenging aspects of building protection, as it must safeguard the entire structure from prolonged exposure to harsh weather conditions. Our experienced professionals prioritize quality at every stage, conducting thorough inspections and ensure optimal system performance and long-lasting protection.

Bathroom
Waterproofing

At Goodwill, we go beyond examining the existing surface condition and extent of water exposure. We assess the anticipated water load and select the most suitable waterproofing treatment tailored to your specific requirements. Since bathrooms are among the most water-intensive areas, constant exposure to moisture makes them highly susceptible to seepage, leaks, and mold growth.

Basement
Waterproofing

Constant groundwater pressure, combined with inadequate sealing, can result in damp and moisture-laden walls, corrosion and rusting of pipes, progressive structural damage. Goodwill develop adaptive waterproofing solutions tailored to your specific requirements, including internal waterproofing, crack treatment, and joint treatment to provide lasting protection against water intrusion.

External Wall Waterproofing

Our external wall waterproofing systems are designed to prevent water ingress and enhance the long-term durability of your building since they are constantly exposed to changing weather conditions. Our process begins with a detailed inspection and surface assessment, based on which we recommend a customized waterproofing solution

Our Waterproofing Process

01 Tank Inspection

We assess the tank structure, surface condition and visible areas of leakage or seepage.

02 Surface Preparation

The surface is cleaned and prepared according to the selected waterproofing system.

03 Waterproofing Application

The suitable waterproofing solution is applied carefully to the required surfaces and details.

04 Final Quality Check

The completed waterproofing work is inspected before the tank is returned to use, based on the project requirements.

Materials & Systems Used

The waterproofing system depends on the tank structure and level of water exposure. Cementitious coatings help protect porous surfaces, while crack sealants and joint treatments address vulnerable areas. Suitable repair materials are also used before application to create a stronger base and reduce recurring seepage.

Frequently Asked Questions

Is waterproofing necessary if the water tank has only minor seepage?

Even minor seepage should not simply be ignored, especially when it keeps returning. Early assessment can help identify whether the issue is related to cracks, joints, surface deterioration or another weakness in the existing tank structure.

Can waterproofing be carried out on an old water tank?

Yes, depending on its condition and accessibility. Existing water tanks can be inspected to understand the source of leakage and determine whether waterproofing is suitable for the structure.

What parts of a water tank can develop leakage?

Leakage can occur through cracks, construction joints, corners, penetrations or deteriorated surface areas. The visible leakage point may not always be the exact location where water is entering or escaping, which is why inspection is important.

How should a tank be prepared before waterproofing?

The tank needs to be properly assessed and the surface prepared according to the selected waterproofing system. Cleaning, addressing unsuitable surface conditions and preparing vulnerable details are important before the waterproofing application begins.

Can waterproofing help protect the surrounding structure from tank leakage?

Yes. A properly selected waterproofing treatment can help reduce water escaping from the tank into surrounding structural or finished areas. The existing condition and source of leakage need to be understood before deciding on the treatment.

Do you provide water tank waterproofing in Coimbatore?

Yes. We provide waterproofing services in Coimbatore for suitable water tanks and other water-exposed structures. Our team can inspect the tank and discuss an appropriate solution based on its condition and leakage concerns.

What information should I share before requesting a tank waterproofing estimate?

It helps to provide the tank type, approximate size, location and details of the leakage or seepage you have noticed. A site inspection can then give our team a clearer understanding of the condition before the waterproofing estimate is prepared.
