Sika is the global waterproofing leader for a reason: full system chemistry that handles below-grade foundations, plaza decks, balconies, wet rooms, and any concrete environment that water has to be kept out of. Gatineau Concrete installs Sika SikaProof sheet membranes and Sikalastic liquid systems as the Sika-system specialist, with the prep, primer, application and protection detail that the system requires. Every project starts with a free written estimate.
Sika has been engineering waterproofing systems for over a century. The product range covers every below-grade and exposed-deck application a project might encounter: pre-applied sheet membranes for foundations to be backfilled, liquid-applied membranes for tight detail work, hybrid systems for plaza decks with traffic exposure, and specialty systems for wet rooms and balconies.
We install Sika systems as the Sika-system specialist, meaning prep, primer, application thickness, and protection layer all follow Sika spec. The system warranty depends on installer compliance with that spec; we deliver to it.
We pick the Sika system that fits the project (SikaProof sheet for backfill, Sikalastic liquid for detail, plaza-deck hybrid for traffic-exposed) based on substrate, exposure and project sequencing.
Prep substrate for Sika
Substrate is cleaned and prepped per Sika spec, cracks repaired with compatible material, joint detail areas isolated, and any moisture issues addressed before primer.
Prime and apply Sika membrane
The Sika primer goes on the prepped substrate, then the matched membrane (sheet or liquid) is applied to engineered thickness, with all corner, joint and penetration detail per Sika spec.
Protect and document Sika
Protection layer is installed where required (drainage board, screed, traffic surface), the system is documented for Sika warranty support, and the install is handed off.
Where Sika shines
Sika System Warranty Needs Installer Discipline
Sika warranty applies when installation follows Sika spec by a Sika-system installer. The warranty extends beyond product to address install method; that combined warranty is what makes Sika valuable on long-term commercial work.
Coordinate with other Sika services on the project (crack injection, repair, floor systems) where multiple Sika products integrate into the larger 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.
