Our Execution Process
Engineering Collaboration
We coordinate with leading building envelope engineers (SDR, RDH, etc.), review project specifications, and secure municipal street-use/sidewalk closure permits.
Substrate Preparation & Chipping
Carefully identify hollow areas, hammer and chip away spalled concrete to expose solid aggregate, and descale rust from exposed steel rebar down to bare metal.
Steel Anti-Corrosion Treatment
Coat exposed reinforcement steel with active, zinc-rich anti-corrosive primer to arrest future oxidation.
Structural Restoration
Refill concrete cavities with high-performance, polymer-modified structural patching mortars (e.g., Sika or BASF systems) and repoint masonry joints using custom compressive strength matched mortars.
Waterproof Membranes & Joint Sealing
Apply polyurethane liquid balcony traffic membranes, route and reseal building expansion joints, and apply breathable elastomeric exterior wall coatings.
Engineered Exterior Restoration for Strata & Commercial Facades
Vancouver's coastal climate—characterized by heavy wind-driven rain, freeze-thaw cycles, and airborne marine salts—places tremendous stress on the building envelopes of strata and commercial high-rises. Over time, concrete absorbs moisture, initiating steel rebar corrosion. As the internal steel rusts, it expands up to ten times its original volume, causing the surrounding concrete to crack, delaminate, and eventually fall away. This concrete spalling is a serious public safety hazard and a liability for property owners. Allweathercoating delivers comprehensive, engineered building restoration solutions designed to address the root cause of deterioration and safeguard your investment.
The Five Core Pillars of Our Restoration Services
1. Structural Concrete Spall & Rebar Repair
Restoring spalled concrete balconies, eyebrows, and slab edges requires precision execution. Our certified technicians follow a rigorous repair protocol:
- Mechanical Chipping: We chip away loose, delaminated concrete until we expose sound aggregate, ensuring we cut behind the rebar to allow for a full mechanical bond.
- Steel Descaling: Exposed steel reinforcement is wire-brushed or sandblasted to remove all surface oxidation and scale.
- Zinc-Rich Anti-Corrosive Coating: We apply a protective, active zinc primer to the steel to inhibit future corrosion cycles.
- High-Performance Patching: Cavities are packed with premium polymer-modified structural patching mortars from industry leaders like Sika or BASF, restoring the structural profile.
2. Brick Masonry Repointing & Joint Restoration
Weathered masonry joints allow water to bypass the rainscreen, rotting internal walls. We perform tuckpointing and brick repointing using custom mortar mixes formulated to match the compressive strength and vapor permeability of the original brick. This prevents mortar from cracking or causing spalls on the brick face. We also replace damaged bricks, clean efflorescence, and apply breathable water-repellent sealants.
3. Balcony & Parkade Waterproofing Membranes
Water ponding on balcony slabs and parkade decks eventually seeps into concrete pores. We install multi-layer, seamless liquid-applied polyurethane membranes that cure to form a flexible, traffic-bearing, slip-resistant waterproof seal. This protects suspended slabs from water ingress, salt penetration, and carbonation, while providing a clean, aesthetic finish for residents and parkade users.
4. Sealant & Caulking Joint Replacement
High-rise buildings undergo continuous thermal expansion and contraction. We rout out failing polyurethane window perimeter caulking and structural expansion joints, preparing the substrate with backer rods before applying premium, high-movement silicone sealants (e.g., Dow Corning 795/790) that carry warranties of up to 20 years.
5. Rainscreen Cladding & Stucco Rehabilitation
We repair stucco cracks and renew failing cladding panels to restore the integrity of the rainscreen system. The facade is finished with high-build, breathable elastomeric coatings that bridge hairline cracks and resist wind-driven rain while allowing interior water vapor to escape.
Engineering Coordination, Photo-Logs & Permitting
Large-scale building restoration requires careful coordination. We work alongside leading building envelope engineering consultants, reviewing drawings, following exact project specifications, and coordinating WorkSafeBC-compliant site safety plans. We handle all city street-use permits, sidewalk closures, and pedestrian overhead hoarding. To ensure complete transparency, our crew compiles daily progress logs and high-resolution close-up photo documentation, providing strata councils, property managers, and engineers with verification of all concealed repairs before they are coated.
Common Questions About Building Restoration in Vancouver
What is concrete spalling and why does it occur on building facades?
Concrete spalling is the cracking, delamination, and flaking of concrete from a building facade. It occurs when moisture penetrates porous concrete and reaches the internal steel rebar. The steel rusts and expands up to ten times its original volume, generating internal pressure that fractures the concrete. On Vancouver facades, wind-driven rain and coastal chlorides accelerate this process significantly.
How do you repair rusted rebar inside a spalled balcony or slab edge?
We chip back the concrete to expose the full circumference of the rusted steel, mechanically grind away all rust to bare metal, apply a zinc-rich anti-corrosive primer, and then pack the cavity with high-strength structural repair mortar.
Do building restoration projects require a building envelope engineer?
For minor cosmetic concrete chipping, engineering is generally not required. However, for structural repairs, suspended slab renewals, or load-bearing concrete restoration, we coordinate directly with qualified building envelope engineering consultants to ensure safety and compliance.
Safety & Access Considerations
Performing building restoration in vancouver requires meticulous planning under WorkSafeBC regulations. Our operations are governed by qualified SPRAT/IRATA technicians who conduct risk assessments, verify structural roof anchors, and set up secondary backup systems. We coordinate ground barricades to isolate work areas, keeping residents, shoppers, and pedestrians safe on the ground.

What materials do you use for patching concrete structures?
We use premium, polymer-modified structural patching mortars, epoxy concrete bonding agents, and zinc-rich anti-corrosive coatings from industry-leading manufacturers (such as Sika or BASF) to ensure durable, long-lasting repairs.
How do you access vertical high-rise facades for concrete and masonry repairs?
We utilize certified industrial rope access (SPRAT/IRATA) and swing stage configurations. Rope access allows us to access hard-to-reach areas quickly without the high cost, noise, and disruption of scaffolding.
What noise levels and resident disruptions should strata properties expect?
Concrete chipping and mortar routing generate significant noise. We manage this by planning structured quiet hours, posting resident notifications 7-14 days in advance, and scheduling noise-heavy work during off-peak hours.
How long does a typical concrete or masonry restoration project take?
The timeline varies widely based on the scale of the damage. A small balcony repair project might take 1-2 weeks, while a full facade restoration on a high-rise tower can take several months, executed in logical phases.
Do you offer warranties on structural building restoration?
Yes. We offer comprehensive labor and craftsmanship warranties, typically paired with 5-to-20-year manufacturer product warranties depending on the membranes, mortars, and sealants selected.
How do you handle municipal street and sidewalk permits in Vancouver?
We manage the entire permitting process with local municipalities, securing street-use permits, sidewalk closure permissions, and parking lane blockages, and setting up WorkSafeBC-compliant pedestrian safety hoarding.
How does Allweathercoating prioritize crew safety during overhead concrete chipping?
Worker safety is our number one priority. Our technicians are fully certified SPRAT/IRATA riggers operating on dual ropes with independent fall-arrest systems. We enforce safety zones on the ground, utilize tool lanyards to prevent drops, and maintain full WCB and comprehensive general liability insurance scaled to the danger of the specific job.
