Mapelastic is the go-to Mapei waterproofing membrane for wet rooms, balconies and exterior decks; Mapeflex covers the joint-detail products that make the system actually work. Las Vegas Concrete installs Mapei waterproofing systems with the matched primer, full joint detail, and the protection layer the system calls for. Every project starts with a free written estimate.
Mapelastic alone is just a membrane; the system is Mapelastic plus Mapeflex joint detail plus the matched primer plus the protection layer. Skip any component and the system underperforms. Mapei's strength is offering the complete chemistry across one brand so the install crew is working with calibrated-together products.
We install the full Mapei system, not pieces of it. Where the project specifies Mapei (often a tile-trade project where the same brand covers SLU through waterproofing through adhesive), we deliver the complete system. Coordinate with adjacent Mapei SLU and Mapei repair for the full Mapei project flow.
We confirm which Mapei waterproofing fits the application (Mapelastic Smart, AquaDefense, etc.), the joint detail products required, and any tile-trade coordination if Mapei adhesive follows.
Prep substrate to Mapei spec
Substrate is cleaned and prepped per Mapei spec, cracks repaired with compatible Mapei product, joints isolated with Mapeflex tape or sealant, and the surface prepared for membrane.
Apply Mapei membrane
Mapelastic is mixed and applied to engineered thickness across the field, with Mapeflex detail at every corner, joint, drain and penetration. Full system, not selective.
Cure and protect
The system cures per Mapei schedule, protection layer or tile adhesive (often Mapei Kerabond) follows per project spec, and the waterproofing is handed off ready for service.
Joint detail is the system
Mapeflex Is Where the Mapei System Lives
The Mapelastic field membrane is the visible part; Mapeflex joint detail is where the system actually holds. Every corner, drain and transition gets the matched Mapeflex tape or sealant. We never skip detail products because the field membrane alone fails at joints.
Mapelastic vs Mapeflex, tile-system path, system warranty.
Mapelastic is the field membrane; Mapeflex is the joint-detail family (tapes, sealants, transition products) that completes the system. Both are needed; using Mapelastic alone fails at the corners.
Often yes, especially when the tile installer is using Mapei adhesive and grout. The whole-system Mapei path keeps warranty paths clean. We install to that integration.
Yes, with the right Mapei system for the deck conditions. We confirm the spec, install with traffic-rated protection where required.
Yes, Mapei has below-grade systems. For most residential foundation work, see also foundation waterproofing for the non-brand-specific service.
Depends on area and detail count. Most projects take a few days through cure; large-scope work stretches longer. The schedule is in the quote.

Full Mapei system on a tile shower install, my adhesive went over it cleanly, warranty path intact for the whole assembly. Trade-coordinated install.

Mapelastic plus full Mapeflex detail on every wet room across a building. Inspector signed off on the system warranty; documentation was complete at handoff.

They never skipped the Mapeflex joint detail to save time, which is what every other contractor I have used does. The result is the difference.
