Mapei Planitop and Mapegrout repair mortars restore damaged concrete before tile install or structural work. Kerabond and Keraflex adhesives complete the system. We diagnose the repair need, select the right Mapei product, and coordinate the adhesive layer so warranty stays intact across the whole assembly.
Mapei's strength is that every layer from substrate repair through waterproofing through tile adhesive is engineered as a single system. When you use Planitop repair under Mapelastic waterproofing under Kerabond adhesive, the warranty covers the whole assembly. If you swap brands at the adhesive stage, the warranty path breaks even if the repair was Mapei.
We install Mapei repair products to restore the substrate, then coordinate with the tile installer or next trade to ensure the matched Kerabond adhesive gets specified. This keeps the system whole and the warranty intact. The repair mortar is only as good as the adhesive that follows it.
We evaluate whether the repair is cosmetic patching, moderate substrate prep for tile, or structural restoration. This determines whether Planitop or Mapegrout is the right choice.
Prepare concrete to spec
Unsound concrete is cut back, the repair area is cleaned and primed with the matched Mapei primer. Substrate prep follows Mapei's technical data sheet exactly.
Mix and place repair mortar
Mapei repair is mixed to manufacturer ratios, placed at the engineered thickness, and finished to match the surrounding concrete surface.
Hand off to adhesive layer
Once the repair cures, we coordinate with the tile installer or next trade to specify Kerabond or the matched Mapei adhesive so the system stays whole.
Warranty and durability
Single-Brand Warranty Across the Assembly
The real value of Mapei repair is that when the whole system is Mapei, the warranty covers every layer. Repair fails? Covered. Adhesive fails? Covered. We make sure the repair is installed to spec and the adhesive layer is coordinated so that warranty path stays open.
Planitop vs Mapegrout, tile system warranty, primer and structural repair.
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.

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.
