Sika's elastomeric chemistry flexes with concrete movement instead of cracking off. We install Sika waterproofing, crack injection, repair mortars and floor systems across Laval, following the full manufacturer sequence. Every job gets a free written estimate and a firm schedule.
Water finds cracks. Sika's elastomeric membranes and sealants are engineered to move with the concrete slab and wall, so they don't crack off the way rigid coatings do. Sika waterproofing (Sikalastic, Sikagard) seals the entire surface before water ever gets in.
When a crack is already leaking, Sika crack injection (SikaFix HH, SikaFlex) fills it from the inside out, stopping the leak and stabilizing the substrate. No excavation needed in most cases.
We evaluate whether the issue is active water ingress, a structural crack, spalling or a finished-surface repair, then select the matching Sika product line and chemistry.
Prepare the substrate
The concrete is cleaned, routed, and brought to the moisture content and profile that the Sika system requires. Cracks are opened and cleared for injection.
Install primer, body, topcoat
We follow the published Sika sequence, applying each layer at the specified temperature, lift thickness and cure time. The chemistry is matched to the environment and load.
Document and warranty
The install is photographed and documented. You receive the product data sheets and warranty information so future work stays compatible with the Sika system.
Elastomeric chemistry
Why Sika Flexes Where Others Crack
Concrete moves. Freeze-thaw cycles, seasonal expansion, settling, and structural loads all cause the slab and walls to shift. A rigid waterproofing coating or sealant cracks when the substrate moves, and water finds the crack.
Which Sika line for which job, injection, waterproofing and warranty in Laval.
Often, yes. Sika crack injection with SikaFix HH polyurethane seals active cracks from inside the wall and stops the leak, without needing to excavate the outside of the foundation in most cases.
Sika waterproofing is a system applied to a whole wall or slab to keep water out. Crack injection is a targeted repair that seals a specific crack already letting water through.
Yes, the right one can. Sika MonoTop repair mortars rebuild spalled and structural concrete to original profile and strength, with the chemistry chosen to suit whether the repair is cosmetic or load-bearing.
Because elastomeric chemistry actually flexes with concrete movement. A rigid coating cracks where the substrate moves, and the leak comes back. Sika systems were developed to flex and seal, which is why they hold up below grade.
Yes. We install Sika products as a system, primer, body and topcoat in the published sequence and chemistry. That is what keeps the manufacturer warranty intact and what makes the install actually perform.
Sika crack injection stopped a leak we had chased with caulking for years. They sealed it from inside and the basement has been dry through two springs.

Full Sika waterproofing on a new foundation. Elastomeric so it can flex with the concrete and not crack off the way the old rigid coating did.

SikaTop repair on a worn loading-dock area. Profile is exact, took our forklift traffic, and they handed over the data sheets for our records.

They install Sika as a full system, not just a coat of the product they have on the truck. That difference shows up in how long the install holds.
