Keeping Water Out with Sika Waterproofing in Detroit
When concrete meets water, the membrane between them has to work. Sika builds waterproofing systems that handle foundation walls, plaza decks, balconies, wet rooms, and any below-grade or exposed-deck condition where moisture intrusion is the enemy. We're a Sika-system installer, meaning every project gets the right product selection, substrate prep, primer, application thickness, and protection layer that Sika engineering requires. Call for a free written estimate.
Sika has spent over 100 years refining waterproofing chemistry. The product lineup spans pre-applied sheet membranes (SikaProof) for foundation walls and blindside applications, liquid-applied systems (Sikalastic) for detail-heavy work and tight corners, hybrid plaza-deck assemblies engineered for foot and vehicle traffic, and specialty formulations for wet rooms and balcony edges.
We install as a Sika-system specialist. That means substrate cleanliness, moisture testing, crack repair, primer selection, membrane thickness, joint detail, and protection layer all follow Sika's engineering spec. The system warranty depends on that compliance; we deliver it.
We evaluate the concrete surface, exposure conditions, and project sequencing to choose between SikaProof sheet (for backfill scenarios), Sikalastic liquid (for detail work), or a plaza-deck hybrid system. The choice drives the entire prep and application strategy.
Prepare the concrete per Sika spec
The slab or wall is cleaned to remove dust, laitance, and contaminants. Cracks are routed and filled with compatible repair material. Moisture is tested and confirmed within limits. Joint areas are isolated and prepped for detail work.
Apply primer and membrane
The Sika primer is rolled or sprayed onto the prepped concrete. Once cured, the membrane (sheet or liquid) is applied to the engineered thickness. All corners, penetrations, and joints are detailed per Sika spec to eliminate weak points.
Install protection and document
Where required, a protection layer (drainage board, screed, or traffic surface) is installed over the membrane. The system is photographed and documented. Warranty paperwork is prepared and handed off with the project.
System vs. product
Why Sika System Warranty Beats Product Warranty
Sika's warranty is a system warranty, not just a product warranty. That means it covers not only the membrane material but also the installation method, substrate prep, and application thickness. A system warranty is what commercial owners actually need, because a failed membrane is usually a failed install, not a failed product.
We maintain Sika-system installer status by following spec on every project. When you get a Sika system from us, the warranty paperwork reflects that compliance. Integrate other Sika products on the same project: SikaTop floor systems, Sika repair, and crack injection all work together in a coordinated scope.
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.

★★★★★
Sika system on our wet-room area, every penetration detailed properly. No leak issues since install. The detail work made the system.

They explained Sika system warranty vs product warranty before quote. The value was obvious. System warranty paperwork came at handoff.
