Our Products

For the market of crack repair, water proofing, water control etc. we supply the following types of polyurethane systems in our program of formulations:

 

Systems

Characteristics & Applications

1. SOLID RESINS / PUR RESIN SYSTEMS FOR CRACK INJECTION

 

 

Erro Grout 223E / Erro Nate 500

Two component polyurethane injection resin for the elastic sealing of cracks in concrete structures; this system is phthalate free and has a mixing ratio from 1 : 1 in volume.

Erro Grout 225 / Erro Nate 300

Two component polyurethane injection resin for the structural sealing of cracks in concrete structures; this system is phthalate free and has a mixing ratio from 1 : 1 in volume. The main advantage is that the material has a high tensile strength.

 

2. SOLID RESIN / FOAM SYSTEMS

 

 

Erro Grout 371 / Erro Nate 500

Two component polyurethane injection system for the elastic sealing of cracks in concrete structures with a unique performance:

a. In case water is present it will form an elastic foam;

b. In case there is no water the material will form a flexible resin like the Erro Grout 223E/Erro Nate 500;

c. Permanent sealing as the same material can be used for the second injection if needed.

This system is phtalates free and has a mixing ratio from 1 : 1 in volume

 

 

3. WATER STOP SYSTEMS BASED ON POLYURETHANES / FOAM TYPES

 

 

Erro Grout 447E / Erro Cat 48
A single component, hydrophobic, water reactive polyurethane to be used as a water stop system producing a relatively stiff polyurethane foam. The main application is to stop or react away flowing water in cracks and soil. This system is phtalates free.

 

4. FOAM / GEL SYSTEMS

 

 

 Erro Grout 686
A single component, hydrophilic, MDI based, solvent and phthalate free polyurethane to be used as a water stop system producing, depending on the amount of water, a tough, flexible polyurethane foam or an elastomeric gel. Mixing ratio polymer to water from 1 : 1 to 1 : 10

 

5. GEL SYSTEMS

 

 

Erro Grout 858A / Erro Nate 858BA two component, hydrophilic, MDI based, solvent and phthalate free polyurethane to be used as a water stop system producing an elastomeric gel. Mixing ratio 858A to 858B is 1 : 1 in volume.
