Morcem® Geogrout
High-conductivity grout for pumping, injecting and filling in geothermal plant heat exchangers.
Additional information
Composition
Product comprised of hydraulic bonding materials, micronized minerals, natural marl soils and other additives.
Features and applications
- Highly fluid and cohesive mixing.
- High resistance to salts.
- No separation or exudation.
- Low content of soluble salts.
- High mechanical resistance.
- Excellent sealing, maintaining continuity between the probe and bore walls.
Instructions for use
- Make the boreholes in the ground and install the probe.
- Fill the interior annular space between the probes and interior bore walls with the mixed grout using a pump fitted with appropriate mixing and pressure control system.
- Mechanically mix with the stated amount of water (5.5-6.3 l per sack) until a fluid consistency is achieved gradually adding the powder to a part of the recommended amount of water.
- If necessary the amount of water added to the mixture can be reduced increasing the fluid viscosity for situations where the ground is very permeable, thick sands or cavities. The injection equipment can be limited in these situations to the pressure of the work necessary.
Cautions and recommendations
- Do not reuse previously mixed product.
- Do not apply under 5ºC nor above 30ºC.
- Do not apply if there is a risk of freezing.
Packaging
15 kg plastic-lined paper bags.
Shelf life: 1 year in sealed original packaging, sheltered from weather conditions and humidity.
