Hot Spray Applied Waterproofing Solutions for all Secondary Containments

Containment and retention basins are required by law to prevent hazardous waste or chemicals from entering the environment through leaks in tanks. The basins are usually made of concrete and have to guarantee the highest sealing security. Even the smallest pore may have serious consequences for people and the environment. 
The secondary containment is intended to safely contain any accidental liquid spill in a second basin on a temporary basis until response teams arrive and the plant has been safely shut down.

There are two main principles that need to be taken into consideration in the design of secondary containments: any liquid must be contained irrespective of its temperature and liquids start cooling down immediately after they leave the primary containment. Taking this into consideration, a secondary containment protection system needs to match both the type and the temperature of the chemicals stored and to bridge cracks in order to ensure that potential leakages can be contained whenever they occur, even in the case of substrate cracks. 

Hot spray systems from the MasterSeal range perfectly match all these requirements and ensure long-lasting protection for the secondary containment structure.

​​​​​​​​​Key benefits at a glance

Crack-bridging

Crack-bridging

Although they are extremely tough, hot spray systems are highly elastic and can bridge a crack of more than 2 mm. Whatever thermal expansion, or cracks may occur in the structure, the membrane will not be affected by any cracks.

Fast curing and dandering

Fast curing

Hot spray membranes take only a few seconds to harden, allowing a very fast return to service and minimizing downtime and risks on the job site.

​​​​

Primer

A primer is the foundation of all systems and ensures adhesion between the protective system and the substrate.

Chemicals and mechanical resistance

Chemical and mechanical resistance

Hot spray membranes are exceptionally robust and resistant to mechanical wear, abrasion and impact stress as well as to chemical attacks.


Conductive layer

The conductive layer is optional and it is applied only when antistatic properties are required.

Durability and maintenance costs

Durability and maintenance costs

Hot spray membranes are a long-lasting and very reliable solution which ensures a significant reduction in maintenance costs during the life cycle of the structures to which they are applied.

​​

Membrane

The membrane is the watertight and flexible layer which gives its properties to the complete system.

Hot stored chemicals: calculation of surface temperature and reduction of up to 30% in repair costs

Two major principles regarding the functionality of secondary containments are: first, a hot liquid has to be contained; second, the liquid starts cooling down immediately after it leaves the primary containment.
