Product Overview

MC-Grout PF is a precision fine-grain, non-shrink cementitious grout from MC-Bauchemie representing the specialised precision grouting segment of the MC-Grout product range — positioned between the coarser general-purpose MC-Grout HES (non-shrink grout with larger aggregate for thicker grout layers) and ultra-fine micro cement injection grouts (MC-Grout 500) for the specific application of base plate grouting where the grout must flow through thin gaps under precision-levelled base plates. The technical distinction of MC-Grout PF from standard non-shrink grouts lies in three characteristics: fine aggregate grading (maximum particle size 1.0 to 1.5 mm — enabling flow under base plates with 10 to 15 mm clearance), non-shrink performance (the grout achieves zero or slightly positive volumetric change during hardening — preventing the formation of voids and gaps under the base plate that would cause partial bearing contact and uneven load distribution), and high compressive strength at 28 days (greater than 55 to 65 MPa — sufficient for the high bearing stress under heavily loaded machine or structural column base plates). The non-shrink property of MC-Grout PF is achieved by a gas-generating mechanism (finely divided iron oxidation or aluminium reaction producing hydrogen gas bubbles) or crystalline expansion mechanism that exactly compensates the normal chemical shrinkage of cementitious materials during hydration — the result is a grout that expands slightly during the plastic state to fill the base plate void completely, and then stabilises at its final dimensions without the long-term shrinkage that causes void formation under base plates in plain cement grout applications. The consequence of void formation under a machine base plate — from inadequate grout flow or post-set shrinkage — is rocking and vibration of the machine during operation, accelerating bearing wear, misalignment, and ultimately structural damage to both the machine and the foundation. Space Arc Engineering supplies MC-Grout PF for industrial construction contractors, erection agencies, plant maintenance teams, and structural repair specialists in Ghaziabad, Delhi NCR, Noida, and Uttar Pradesh.

Applications

• Machine base plate grouting in manufacturing and process plants — precision grouting of the base plates of heavy industrial machines including CNC machining centres, turbines, compressors, pumps, motors, generators, and process equipment in manufacturing facilities, power plants, and process industries in Delhi NCR and Uttar Pradesh — where machine alignment accuracy (typically to within 0.02 to 0.05 mm over the machine span) requires a grout that achieves 100 percent bearing contact under the base plate without voids, and where machine vibration during operation requires the grout to be high-strength, dense, and void-free to transmit vibration loads without grout fatigue or cracking
• Column base plate grouting in steel-framed buildings and industrial structures — grouting the gap between the fabricated steel column base plate and the concrete column pedestal or foundation block in steel-framed industrial buildings, warehouses, portal frame structures, and multi-storey steel buildings where the column base plate is levelled by machined shims or levelling screws and the gap below the plate must be completely filled with non-shrink grout to provide full bearing from the column down to the foundation without point loading at the levelling shims
• Bridge bearing pedestal grouting — precision grouting of elastomeric bearing pads and pot bearings on bridge abutments and pier caps where the bearing must sit on a flat, void-free grout bed at the precise design level — incorrect grouting of bridge bearings causes eccentric loading on the bearing, premature bearing distortion, and differential settlement of the bridge deck — MC-Grout PF precision grout ensures the bearing sits on a fully supported, level grout pad meeting MORTH and IRC bearing installation specifications
• Anchor bolt and foundation bolt grouting — grouting of anchor bolt pockets in machine foundations, process equipment foundations, and structural column bases where the annular gap around the bolt must be completely filled with high-strength, non-shrink grout that bonds the bolt to the foundation concrete and allows full design load transfer from the machine or structural frame to the foundation through the anchor bolt — MC-Grout PF fine grain allows complete filling of anchor bolt pockets as small as 50 mm diameter
• Precast column and beam connection grouting — grouting of the joint between precast reinforced concrete columns and precast column bases in precast frame construction, and grouting of grouted splice sleeves and column-beam joint pockets in precast structures where the grout must develop high early strength (for rapid precast erection cycle) and achieve full bearing contact in the confined joint cavity to ensure monolithic structural connection behaviour

Key Advantages

• Fine grain for flow under narrow base plate clearances — maximum aggregate size of 1.0 to 1.5 mm allows the mixed grout to flow freely under base plates with 10 to 15 mm clearance at a fluid consistency — the fine aggregate size ensures the grout particle size is not larger than one-third of the minimum gap dimension, preventing aggregate bridging that would cause incomplete grout flow and partial bearing contact — the critical criterion for base plate grout selection
• Non-shrink — zero void formation under base plates — the non-shrink formulation ensures the grout volume at final hardened state is equal to or slightly greater than the plastic volume at the time of placement — compensating the cement hydration shrinkage that would otherwise create a thin gap between the grout and the underside of the base plate — void-free full bearing contact is the fundamental performance requirement for machine and structural base plate grouting
• High compressive strength for heavy machinery and structural bearing — greater than 55 to 65 MPa at 28 days provides the high bearing capacity required under heavily loaded machine base plates and structural column bases — capable of supporting the bearing stress from 10 to 100 tonne machines and structural column loads of 2,000 to 10,000 kN without grout crushing or plastic deformation under sustained load
• Fluid to plastic consistency range for different applications — the mixing water quantity can be adjusted within the manufacturer-specified range to achieve either fluid (self-flowing) consistency for narrow base plate gaps where full flow is required, or plastic (stiff, trowelable) consistency for vertical anchor bolt pocket filling where the grout must not slump out of the pocket during filling — the consistency range provides one product that covers both free-flow and packed-fill grouting applications
• Compatible with machine foundation vibration environment — the high strength, dense microstructure, and low porosity of hardened MC-Grout PF provides excellent resistance to fatigue under cyclic vibration loading from rotating machines — the grout does not crack, soften, or lose bond to the base plate under repeated vibration cycles at the frequencies typical of industrial rotating equipment (10 to 100 Hz), providing long-term vibration-resistant machine mounting
