Oshawa Concrete Restoration Using Mapei Repair & Adhesives
Planitop and Mapegrout handle the concrete substrate; Kerabond and Keraflex carry the tile layer. Oshawa Concrete sequences both so the assembly stays one warranted Mapei system. Free written estimate on every job.
How Mapei Repair + Adhesives Keeps the System Intact
Most concrete restoration jobs involve more than patching a slab. When tile goes down afterward, the repair mortar, the waterproofing membrane, and the tile adhesive all need to speak the same chemical language. Mapei engineers those layers to work together, so a Planitop repair under a Mapelastic membrane under a Kerabond adhesive bed is a single traceable system, not three separate products from three separate manufacturers.
On Oshawa projects where tile follows concrete repair, we select the right Planitop or Mapegrout product for the substrate condition, apply the matched Mapei primer, and finish the repair surface to the tolerance the tile layer requires. When the tile contractor arrives, the substrate is ready and the adhesive recommendation is already in hand.
We look at the slab or wall surface, identify whether the situation calls for cosmetic patching (Planitop range) or load-bearing structural restoration (Mapegrout high-strength), and document the repair scope before any product is opened.
Prepare the substrate to Mapei tolerances
Unsound concrete is cut back to solid material, contaminants are removed, and the repair zone is profiled to the bond depth Mapei specifies. The matched Mapei primer goes down before any mortar touches the slab.
Place and finish the repair mortar
Mapei repair mortar is gauged to manufacturer water ratios, placed at the engineered thickness for the product selected, and finished flush with the surrounding concrete surface so the next layer lands on a flat, consistent plane.
Hand off to the tile system
Once the repair has cured to Mapei's specified window, we confirm the surface is ready and pass the Kerabond or Keraflex adhesive recommendation to the tile installer, keeping the whole assembly within the Mapei warranty envelope.
Why the warranty path matters
Protecting the Whole-Mapei System Through Every Layer
A concrete repair that performs well in isolation can still void a tile system warranty if the adhesive above it comes from a different manufacturer. Mapei's warranty structure covers the full assembly, from the repair mortar at the bottom to the grout at the top, but only when each layer is a Mapei product installed to Mapei spec. Introducing a competing adhesive brand at the tile layer breaks that chain, even if the Planitop or Mapegrout repair underneath was flawless.
Oshawa Concrete tracks which Mapei products go into each layer and documents the install sequence so the warranty path is clear if a question comes up later. For vertical and overhead repairs, we select the non-sag Mapei formulations that hold position during cure rather than slumping before the mortar sets. That product selection detail is the difference between a repair that lasts and one that needs to be redone.
Planitop vs Mapegrout, tile system warranty, primer requirements, and structural applications.
Planitop is the cosmetic-to-moderate repair family; Mapegrout covers structural repair with high-strength bonded chemistry. We pick based on the repair situation.
For whole-system warranty path, yes. Mixing brands at the adhesive layer breaks the system warranty even if the repair was Mapei. We coordinate accordingly.
Yes, the Mapegrout high-strength formulations are engineered for structural load. We pick the matched product for the engineered spec.
Yes, with the non-sag formulations in the Mapei range. Standard horizontal repair sags vertically; the vertical/overhead products stay in place.
Properly matched and installed Mapei repairs outlast the surrounding concrete in most service environments. Bond is engineered to be the strongest part of the assembly.
Mapei Planitop substrate repair under my tile install. Same brand through the whole assembly, warranty path stayed clean. The system coordination pays off.

Mapegrout structural repair on a load-bearing element. Engineer signed off on the repair spec, cured cleanly, structurally restored to spec.

They coordinated Mapei repair with the tile contractor's Mapei adhesive choice. Single-brand warranty path the customer wanted. Real trade coordination.

★★★★★
Vertical wall repair with the non-sag Mapei product, stayed in place during cure where a horizontal product would have slumped. Right tool for the situation.
