Tank, Reservoirs and Underground Structures

Holderchem offers a wide range of bituminous products for soil exposed to ground moisture, wet areas, and pools, suitable for new constructions and renovations. Here are the elements included in this range:

Torch-applied bituminous membranes: These membranes are designed for application using a torch, ensuring strong adhesion and reliable waterproofing.

Self-adhesive bituminous membranes: These membranes have an adhesive coating and a peel-off anti-adhesive film. They provide easy installation and excellent adhesion.

Cold-applied bitumen and liquid membranes: These bituminous products are designed for low-temperature application without the need for pre-heating. They are available in liquid form, making them easy to apply on different surfaces.

Thermofusible bitumen and polymer-modified bitumen: These types of bitumen are heated before application to the substrate, allowing optimal adhesion and the formation of a fully bonded waterproofing layer. The added polymers enhance the performance and durability of the coating.

In addition to these bituminous products, Holderchem offers a below-ground waterproofing system called the “double joint.” This system combines the resistance, chemical resistance, and puncture characteristics of high-density polyethylene with the self-sealing properties of sodium bentonite clay. It provides exceptional waterproofing with a resistance to hydrostatic water pressure up to 46 meters. This system prevents water infiltration between the membrane and concrete surfaces, has high puncture resistance, is non-toxic, and has the ability to self-heal. Moreover, it can be quickly and easily applied to fresh concrete, even at extreme temperatures ranging from -30°C to +55°C.
