Background

Distell is a global business with roots in South Africa, that produces and markets a diverse portfolio of award-winning alcoholic brands that have been crafted by extraordinary people across the world.

After conducting an extensive site survey, it was found that the sealant used to coat the fasteners and the joints in many areas has delaminated and cracked. Not all of the joints and fasteners have been treated. This allows water and other contaminants to migrate beneath these areas and cause adverse effects such as corrosion to the underlying substrate as well as leaks. The circumference joint had not been sealed with a water tight solution. This can allow water to migrate into this void causing the topping and adjoint screeds to delaminate and crack. Possible environmental contamination caused by the leaking tank.

If urgent remedial action had not be taken, these repairs could be extremely costly and serious structural renovations may be required.

Solution

Sanika Waterproofing Specialists proceeded to restore the tanks with a high pressure wash to the entire surface area, using clean potable water and stripping and removing all obsolete coatings where necessary to prepare the surface area for grinding of the steel substrate. All floor/wall corners were coved. Once dry and the moisture content of the cementitious floor was below 10%, the entire surface area was wiped down in preparation of the polyurea application.

Primed the entire surface using Quickprime 2k SF to cure for at least 3 hours. Once cured, we applied Quickspray Industrial Pure Polyurea Dark Blue to achieve a DFT of at least 3mm over the entire internal surface.

On completion of site prep, we worked day and night to ensure the job was completed on time Sanika Waterproofing Specialists can be proud of this Calamity Tank
