When a machine sits on a concrete pad, the grout underneath has to stay put. MasterFlow non-shrink grout holds its dimensions through cure, transferring load from the equipment sole plate into the foundation without gaps or settlement. Pittsburgh Concrete installs MasterFlow for industrial equipment commissioning, structural retrofits, and any baseplate where engineered grouting prevents failure. Free written estimate on every project.
Ordinary cement grout shrinks as it cures. For most masonry, that shrinkage is invisible. Under a machine baseplate, it is catastrophic. The grout pulls away from the sole plate, creating voids that break the load path. The equipment rocks, vibrates, and settles unevenly. MasterFlow non-shrink chemistry prevents that by holding dimensions through the entire cure cycle.
The grout stays in contact with the baseplate, transferring the machine's weight directly into the foundation. Load flows through a solid, engineered medium instead of through gaps and micro-voids. That is the difference between a machine that runs smoothly and one that fails early.
The machine manufacturer specifies the grout type and performance requirements. We confirm that spec, cross-check any project engineer notes, and select the matched MasterFlow product from the BASF range.
Prepare the cavity
The baseplate cavity is cleaned, anchor bolts are confirmed in place, the baseplate is leveled and shimmed, and the cavity walls are prepped to receive grout.
Mix and place to spec
MasterFlow is mixed to the exact BASF water ratio. That ratio is not negotiable; it is engineered into the non-shrink chemistry. Grout is placed by gravity flow, pump, or pressure injection depending on cavity geometry.
Cure and commission
The grout cures per BASF schedule (hours for rapid-set epoxy, days for high-strength cementitious). Once cured, the equipment is commissioned and the install is documented for the equipment file.
The critical detail
Water Ratio Discipline Separates MasterFlow Success from Failure
MasterFlow non-shrink performance is calibrated to a specific water ratio. Too much water and the grout shrinks like ordinary cement. Too little and it will not flow into the cavity. We mix to the BASF spec ratio every single batch because anything else compromises the engineered behavior that makes the product work.
That discipline is invisible in the finished install but shows up in load-transfer performance. The grout stays in contact with the baseplate. The equipment runs without settlement or vibration issues. The retrofit baseplate that failed with standard grout now holds because the right product was used correctly.
Cementitious vs epoxy, mix ratios, baseplate spec and commissioning.
Cementitious for most baseplate grouting (high compressive strength, good non-shrink performance, lower cost). Epoxy for higher-load or chemically aggressive environments and where rapid set is needed. We pick based on the spec and load.
Because the non-shrink performance is calibrated to a specific water ratio. Off-ratio mixing compromises the engineered chemistry, the grout shrinks during cure, and the load-transfer path through the baseplate is degraded.
Yes, for larger cavities or pressure-required installs. Most baseplate grouts go in by gravity flow with appropriate flow techniques; pressure injection is reserved for specific geometries.
Cementitious products typically cure to load-bearing strength in days; rapid-set epoxy can reach service strength in hours. The exact cure schedule is in the BASF product spec; equipment commissioning follows it.
Yes, MasterFlow products include formulations for structural anchor grouting where engineered non-shrink performance is critical. We pick the right product from the BASF range.
MasterFlow under a turbine baseplate, full non-shrink performance verified at commissioning. Equipment runs without vibration issues, no settlement at the pad. Real engineering grouting.

They mixed to the BASF water ratio exactly every batch. The discipline is invisible but the result shows in load-transfer performance through the cured grout.

Equipment retrofit with MasterFlow regrouting on a baseplate that had failed. New install holds; the original had used standard grout and shrunk away from the plate. Right product made the difference.

Rapid-set epoxy MasterFlow on a tight commissioning timeline. Cured to load strength inside the window we had. The right product within the BASF range matters.
