BASF MasterInject 1380

MasterInject 1380 is TRSC's alternative structural epoxy injection specification, technically equivalent to Sika Sikadur-52 LP and selected on the same supply chain alignment grounds as the alternative MasterBrace LAM and MasterEmaco S 488 CI specifications. The product is the appropriate structural injection nomination on three job profiles: (1) where the project's repair-mortar specification is already MasterEmaco S 488 CI and a single-supplier MBS system is the integrated specification; (2) on hybrid projects where MasterEmaco patch repair, MasterProtect coatings and MasterBrace strengthening are also nominated and the materials submittal is simplified by a single-supplier system; (3) where the MasterInject technical support and design assistance offering provides additional value on the project. The pitfalls and engineering considerations are essentially identical to those for Sikadur-52 LP: crack activity classification (only dormant cracks are appropriate for structural epoxy injection — active cracks must first be stabilised, with the ongoing movement quantified through monitoring before the injection specification is issued), crack moisture (substrate must be dry; the product is not moisture-tolerant and weeping cracks must be water-cut-off with polyurethane foam injection ahead of any structural epoxy work), and injection technique (introduce from one end, work progressively along the crack length, demonstrate technique on first crack as a witness hold point). One MasterInject-specific consideration is the slightly different viscosity (~250 mPa.s vs. ~290 mPa.s for Sikadur-52 LP), which makes MasterInject 1380 marginally more penetrative on very fine cracks (below 0.3 mm) but otherwise functionally equivalent. TRSC remediation designs that nominate MasterInject 1380 include the surface port specification (typically MasterInject IP-200 ports or equivalent), the injection pump specification, the injection sequence, and a witness hold point for the first crack injection. Site QA includes batch numbers, ambient and substrate temperature recording, photographic record of port locations, and post-injection core sampling at agreed frequency to verify resin penetration through the crack depth. The Form 15 RPEQ certification on the injected element references the crack injection as part of the structural restoration scope, and the certification supporting investigation file retains the injection logs and core samples. The product was used on the 140 William Street basement remediation where structural cracks in basement wall concrete required epoxy injection following polyurethane water cut-off, with the MasterInject specification aligned with the MasterEmaco repair mortar already nominated on the project. The single-supplier system simplified site logistics and removed the cross-brand compatibility concerns that arise when multiple suppliers' products are used in the same repair.
