Keeping Water Out with Sika Waterproofing in Pittsburgh
Water finds every crack and joint. Sika's engineered membrane systems stop it before it becomes a problem. We install SikaProof sheet membranes and Sikalastic liquid coatings on foundations, plaza decks, balconies, and wet rooms across Pittsburgh. As a Sika-system specialist, we handle substrate prep, primer, application thickness, and protection detail to Sika spec, which is what the system warranty actually requires. Free written estimate on every project.
Sika's Waterproofing Chemistry Solves Real Problems
For over 100 years, Sika has built waterproofing systems that work in the harshest conditions. The product line spans pre-applied sheet membranes for below-grade work, liquid-applied systems for detail-heavy areas, hybrid plaza-deck assemblies rated for foot and vehicle traffic, and specialty coatings for wet rooms and balconies. Each system is engineered for its specific exposure.
We install as a Sika-system specialist, meaning every step follows Sika's specification: substrate cleaning and prep, primer selection and coverage, membrane application to engineered thickness, and protection layer installation. The system warranty depends on this compliance. We document the install so your warranty is backed by both product and method.
We evaluate the concrete surface, exposure conditions, and project timeline to choose the right Sika product: SikaProof sheet for backfilled walls, Sikalastic liquid for tight details, or plaza-deck hybrid for traffic-exposed areas.
Clean and prepare per Sika spec
The slab or wall is cleaned to remove dust and contaminants, existing cracks are repaired with compatible material, joints are isolated, and moisture testing confirms readiness before primer application.
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. All corners, penetrations, and joints are detailed per Sika specification.
Install protection and document
Where required, the protection layer (drainage board, screed, or traffic surface) is installed over the membrane. The completed system is documented and photographed for warranty support and handoff.

Why Sika System Warranty Matters More Than Product Warranty
A product warranty covers material defects. A system warranty covers the entire installation method. Sika's system warranty applies only when a Sika-system installer follows Sika spec. That distinction is critical: it means the warranty protects you against installation failure, not just material failure. On a 20-year commercial project, that's the difference between a real guarantee and a limited one.
Integrate other Sika services into your scope: crack injection for pre-existing damage, repair systems for substrate restoration, and floor systems for interior protection layers.
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.
