Water intrusion and concrete deterioration demand precision. We apply Sika elastomeric membranes, injection systems, structural mortars and floor coatings as complete assemblies, following the manufacturer's chemistry and sequence. Every project includes a free written estimate and a firm timeline.
Concrete fails when water finds a path. Sika waterproofing membranes (Sikalastic, Sikagard) are elastomeric, meaning they move with the slab or wall instead of cracking and peeling like rigid coatings do. This flexibility is what keeps water out year after year in Pittsburgh's freeze-thaw cycle.
When a crack is already active and leaking, Sika crack injection (SikaFix HH, SikaFlex) fills from the inside out, sealing the path and stabilizing the substrate without exterior excavation. For spalled or structurally compromised areas, Sika MonoTop repair mortars rebuild to the original profile and load capacity. The topcoat layer comes from SikaTop and floor system products, completing the assembly. This approach is why our basement waterproofing and foundation repair work holds.

How We Apply Sika Systems in Pittsburgh
Assess the concrete and select the product
We evaluate whether the issue is preventive waterproofing, an active leak, structural spalling or a finished surface, then match the Sika line and chemistry to the substrate and environment.
Prepare the surface to spec
Concrete is cleaned, routed, and brought to the moisture and profile that the Sika system requires. Cracks are opened and cleaned for injection work.
Install primer, body, topcoat in sequence
Each layer goes down in the published Sika order, at the correct temperature, lift thickness and cure time. The chemistry is matched to the environment and load.
Document and hand off warranty
The install is photographed and documented. You receive the product data sheets and warranty information so future work is compatible with the Sika system.
Below-grade specialist
Why Sika Waterproofing Outperforms Below Grade
Most of our Sika work is below grade, where water pressure and concrete movement are constant. Sika waterproofing systems are elastomeric, so they flex with the slab and wall instead of cracking and leaking the way rigid coatings do. This is the difference between a one-time install and a repeat project.
When a crack is already letting water through, Sika crack injection seals from inside without excavation. For concrete that is spalled or structurally weak, Sika MonoTop mortars rebuild to the original profile and strength. The result is a foundation or basement slab that stays dry and stable.
Which Sika line for which job, injection, waterproofing and warranty in Pittsburgh.
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.
Client reviews
What Pittsburgh Clients Say About Their Sika Installs
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.
A. D.
Builder
★★★★★
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.
J. E.
Commercial property manager
★★★★★
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.
