New build and repair of sewage treatment plants and sewers

Sewage treatment plants and sewers are exposed
to a permanent chemical and mechanical attack
by sewage from households and industry. Due
to the changing climate conditions and the resulting
extreme rain or flood masses, the systems and
channels are extremely stressed and damage that
their function is no longer guaranteed.

A material with high resistance to chemical and
mechanical attacks is necessary for the maintenance
of these systems.
This material should also be able to be processed

flexibly on site and should not require any complex
machinery.

Damage causes in a sewage treatment plant
- due to mechanical wear
- through frost and de-icing salt
- due to chemical attacks or solvents
- due to concrete corrosion in closed systems

UHPC Ultra High Performance Concrete
UHPC are special concrete products with a minimum
compressive strength of 130 MPa and a water/cement
ratio of less than 0.2.UHPC products can be used very
well for the rehabilitation of concrete - and steel structures.
UHPC products can increase to be rehabilitated
construction next to the corrosion protection even
with admixture of ceramic aggregates the static
bearing capacity.

Benefits of UHPC
- Easy installation as Spray, Mortar, Cast
- Very high corrosion resistance
- Extremely wear-resistant
- Extreme low to no carbonation
- Usable at very high humidity
- Very high impact strength
- Extreme low chloride permeabilit
- Very high resistance to mechanical loads
- No pore formation
- Maritime and port water resistant    
- Installation in the water possible
- Duration resistant
- The standard drying time is under 48 hours
- Penetrates into the smallest joints and cracks,
   and closes them permanently
- Joint less installation
- Very good thermal shock resistance
- Absolutely frost and de-icing salt resistant
