Environmental Control for Large-Scale Underground Water Tank Repair

When a water tank has a capacity of more than 18,000 cubic metres, maintaining the correct temperature and relative humidity levels is challenging. When looking to maintain an underground water tank of this scale at a rural site, the structural engineering contractor engaged Polygon’s specialist teams to help ensure very specific environmental parameters were met.

The overall objective of the project was to securely seal the water tank with a solvent-free epoxy adhesive and repair mortar that has been specially formulated to satisfy the stringent requirements for applications involving drinking water. The adhesive will only cure successfully, however, if environmental conditions are maintained within certain thresholds for a consistent period of seven days.

The Process

Polygon was tasked with providing the desired ambient conditions for the contractor to carry out its work. In the preparation phase, our specialist team carried out to meet the temperature and dehumidification requirements. The equipment would run on a generator, which Polygon UK provided alongside the associated power equipment and fuel tank.

The Solution 

Thanks to the comprehensive planning and preparation work, Polygon UK were able to install all equipment on time and within budget. The delivered set-up ensured ideal ambient air conditions were maintained 24 hours a day for the seven days required. 

The Outcome

The solution provided enabled the contractors to complete the required repair works on time and within budget on behalf of the client.

The necessary calculations were carried out to determine the scale of equipment needed!
