Keeping Water Out of Las Vegas Concrete Structures
When a foundation, deck, or wet room needs to stay dry, Sika waterproofing membranes are engineered to handle it. We install SikaProof sheet systems for below-grade work and Sikalastic liquid membranes for detail-intensive applications, following Sika's full specification so the system warranty covers both product and installation. Free written estimate on every project.
Sika has spent over 100 years refining waterproofing chemistry for every exposure condition. The product line spans pre-applied sheet membranes for backfilled foundation walls, liquid-applied systems for tight corners and penetrations, hybrid plaza-deck assemblies rated for foot and vehicle traffic, and specialized formulations for wet rooms and balconies.
We install as a Sika-system specialist, which means substrate prep, primer selection, membrane thickness, and protection layer all follow Sika's engineering spec. The system warranty depends on this compliance; we deliver it on every project.
We choose between SikaProof sheet (for backfill-ready walls), Sikalastic liquid (for detail work and tight spaces), or plaza-deck hybrid (for traffic-exposed decks) based on substrate type, water exposure, and construction sequence.
Prepare the concrete surface
The slab or wall is cleaned to Sika spec, existing cracks are repaired with compatible material, joints are isolated, and moisture testing confirms readiness before any primer is applied.
Apply primer and membrane
Sika primer is rolled or sprayed onto the prepped concrete, then the selected membrane (sheet or liquid) is applied to the engineered thickness, with all corners, joints, and penetrations detailed per Sika specification.
Install protection and finalize
Where required, the protection layer (drainage board, screed, or traffic surface) is installed over the membrane, the system is documented for warranty registration, and the project is handed off complete.
Warranty advantage
Sika System Warranty Covers Installation
Sika's warranty is not just product replacement; it covers the entire system when installed by a certified installer following Sika spec. This means the warranty protects against installation defects, not just material failure. That distinction matters on long-term commercial projects where water intrusion can be costly.
SikaProof vs Sikalastic, plaza decks, warranty and substrate prep.
SikaProof is a pre-applied sheet membrane for substrates that will be backfilled (foundation walls before backfill, blindside walls in tight excavations). Sikalastic is a liquid-applied membrane for tight detail work, plaza decks, balconies. We pick based on project specifics.
Yes, Sika has plaza-deck systems engineered for traffic-exposed waterproofing with protective wear surfaces. We install the full system including the protection layer that handles traffic without compromising the membrane.
System when installed by a Sika-system installer to Sika spec. That extends warranty beyond product replacement to cover install integrity, which is what commercial customers actually need.
Specific prep per system: surface cleanliness, moisture limits, crack repair, joint detail. The Sika spec defines the exact requirements; we follow them because skipping prep voids the system warranty.
Depends on system and area. Foundation walls can be done in days; plaza-deck systems with multiple layers stretch longer. The full schedule is in the quote.
