    ​​Hot Spray Applied Waterproofing Solutions​

    Hot spray waterproofing systems are the most efficient solutions in many waterproofing and protection applications thanks to their high performance and the fact that they can form a fully bonded seamless shield that avoids welds and seams which are typically the weaker spots in any waterproofing system.
    Hot spray systems are highly versatile thanks to their quick and easy application, lightweight; they are also highly resistant to chemical attacks and mechanical stress.

    The systems are based on polyurethane/polyurea waterproofing membranes which are spray applied on-site and selected depending on the structure to be protected. The membrane can be bonded almost to any type of substrate e.g. concrete, old bitumen sheets, steel or others, thanks to a primer and can be covered by a thin top coat layer, forming an extremely resistant and seamless protection skin.

    ​​​Key benefits at a glance​



    Although they are extremely tough, hot spray systems are highly elastic and can bridge a crack of more than 2 mm. Applied on a car-parks, they will stop the penetration of water and chemicals into the structure.

    Fast curing

    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.

    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.

    Durability and maintenance costs

    Durability and maintenance costs

    Hot spray systems 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.

    ​Main fields of application​

    Hot Spray Roofing


    Hot spray waterproofing systems can be easily applied to all kinds of buildings, all roof shapes, substrates and design details. They are lightweight and resistant to all weather conditions.

    Hot Spray Car parks

    Car parks

    Hot spray systems ensure optimum protection against the different challenges of a multi-storey car park and prevent rain water, snow and deicing salts from migrating to the lower levels or inside the building. 

    Hot Spray Water tanks

    Water tanks

    Hot spray systems cope very well with the specific challenges of water storage where the water tries constantly to escape through the weakest parts of the structure.

    Hot Spray Secondary containment

    Secondary containment

    The combination of excellent chemical resistance with crack-bridging properties makes the hot spray systems a preferred solution for secondary containment applications.
