Keeping Water Out with Sika Waterproofing in Regina
Below-grade foundations, plaza decks exposed to traffic, balconies, wet rooms, every concrete surface that needs to stay dry requires a waterproofing system engineered for that specific exposure. Sika builds membranes and coatings for all of them. Regina Concrete applies SikaProof sheet membranes and Sikalastic liquid coatings as a certified Sika-system installer, meaning substrate prep, primer, application thickness, and protection detail all follow Sika specification. System warranty depends on that compliance. Free written estimate on every project.
Sika's 100+ years in waterproofing chemistry means the product line covers every scenario: pre-applied sheet membranes for foundation walls that will be backfilled, liquid-applied systems for tight corners and penetrations, hybrid plaza-deck systems rated for vehicle traffic, and specialty formulations for wet rooms and balconies. Each product is engineered for its exposure.
We install as a Sika-system specialist. That means the substrate gets prepped to Sika spec, the primer is applied at the right rate, the membrane goes down at engineered thickness, and protection layers are installed per the system design. The warranty covers not just the product but the installation method itself, which is what matters on long-term commercial work.
We evaluate the substrate, exposure conditions, and project timeline to choose the right Sika product: SikaProof sheet for backfilled walls, Sikalastic liquid for detail work, or a plaza-deck hybrid for traffic-exposed surfaces.
Prepare the concrete surface
The substrate is cleaned, any active cracks are repaired with compatible material, joints are isolated, and moisture testing is done per Sika spec. Skipping this step voids the warranty.
Apply primer and membrane
The Sika primer is rolled or sprayed at the specified rate, then the membrane (sheet or liquid) is applied to engineered thickness. All corners, joints, and penetrations are detailed per Sika specification.
Install protection and document
Where required, the protection layer (drainage board, screed, or traffic surface) is installed to shield the membrane. The system is documented for warranty registration and handed off to the owner.

Sika System Warranty Requires Installer Precision
Sika's warranty is not just a product guarantee. When installed by a certified Sika-system installer following Sika specification, the warranty covers the installation method and materials together. That system-level coverage is what protects a commercial property long-term.
On multi-product projects, we integrate Sika floor systems, Sika repair, and Sika crack injection so the waterproofing works as part of a larger concrete strategy. Every detail is documented for warranty support.
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.
