Backfill Grout Mixing Equipment
Backfill Grout Mixing Equipment is important part of Grout Solution Transport. We can design equipment to suit the needs and budget according to the project of the customer. We can supply used equipment for customer as well.
Backfill Grout Material
UMAT understands the performance requirements and the difficulties our customers have in designing specific grouts, whether single component, active and non-active, A+B grout mixes, etc based on the TBM equipment and logistics available. UMAT have a full range of admixtures to suit all backfill grout application methods, together with experts in the field to support you all the way.
Soil Conditioning Foams / Clay dispersants
UMAT understand how the geological conditions can change from one advance to the very next and the need to adjust technology parameters [ FIR & FER ] such as using Soil Conditioning Foams to ensure the highest excavation efficiency of all soil types, whether sandy silt, clay or highly abrasive rock.
Tail Grease Products
We offer a selection of tail grease products inclusive of first fill grade suitable foruse in shielded tunnel boring machine (TBM), where wire brushes are used to form a barrier between the tail shield and concrete segments. Our tail grease products effectively seal off any ingress of water, muck and backfill grout back into the tailend of the TBM. The tail grease range shows excellent adhesion properties to all substrates and good pumping properties.
Water swelling Rubber Sealing
A countless of joints can be produced while sealing segment joints. The construction works such as subways, water supply and sewer systems in cities are likely to be required for water-expanding sealant materials that would provide a superior watertight performance for underground construction. The design for water-stop and pressure is also critical in order to prevent a leak of water from concrete joints.
