UHPC Liquid-tight constructions

Liquid-tight constructions are becoming increasingly important for the economy and insurance companies worldwide. 

In the past, industries such as refineries, seawater desalination plants, sewage treatment plants,
hydroelectric power plants, offshore industries, etc. were particularly interested. There is a huge range of sealing systems for concrete structures. Most systems are expensive, complex to install and do not have the same life expectancy as you would expect from the structure. So the sealants have to be applied several times, which in turn leads to problems and enormous
costs. For a few years now, there has been an increasing demand for coastal protection and especially flood protection structures that have to withstand the constant attack of moving seawater caused by high and low tides, but also by enormous wave movements.

Another growing problem is the rapid change in the climate and the ever-increasing amounts of rainfall that lead to inland flooding and, among other things, also flood residential buildings worldwide, which then have to be repaired in a time-consuming and costly manner. Concrete sealants are of limited or no help here.

One solution is concrete structures made of HPC or UHPC concrete. Here, waterproofing can already be achieved with a wall thickness of 10 - 15 mm. This concrete layer can be subsequently applied to any substrate in industry as well as in residential buildings. This is also possible in countries with predominantly natural material constructions.  
If the ground floor is completely built of HPC or UHPC or provided with a protective layer, no flood water, which is usually also dirty water, can penetrate into the building structure. 

After the floodwater has disappeared, the walls and floor can be cleaned with locally available cleaning machines such as high-pressure water jets, after which this area is immediately habitable again.

In industry, a UHPC layer can completely prevent or hold back breakthroughs for a very long time in the event of liquid attack from the outside, i.e. from floodwater masses, or from the inside in the event of ruptures or leaks in liquid tanks.

Sewage treatment plants can be constructed directly from HPC or UHPC, or they can be retrofitted after prior inspection of the building structure. The same applies to biotank systems for the production of biogas.
