When you hire a concrete repair contractor, you are not just buying materials and labour — you are buying a process. The outcomes that matter most to property managers and strata councils — a repair that lasts, work done on schedule, no surprises on the final invoice, and a team that shows up and communicates clearly — are the product of a disciplined, structured approach to the work. At Miyagi Construction, we have developed our process around what we have learned from years of concrete repair and restoration work across Vancouver’s Lower Mainland. Here is how we approach every project, from first call to final inspection.
Step 1: Site Assessment and Condition Investigation
Every concrete repair project starts with a proper site assessment. We do not quote off square footage estimates or photos — we come to your property and look at the actual conditions. Our assessment typically includes a systematic visual inspection of all concrete surfaces for spalling, cracking, delamination, efflorescence, rust staining, and evidence of water infiltration; a hammer-sounding survey to identify delaminated areas that are not visually apparent; crack mapping to document crack locations, widths, and patterns to help diagnose root cause; a drainage assessment to review the drainage system and any evidence of ponding or improper slope; and, where waterproofing is present, an evaluation of its condition and remaining useful life. This assessment allows us to provide you with a genuinely accurate scope of work — not an estimate that will balloon with change orders once the project starts. When we find unexpected conditions during construction, we communicate immediately with the client before proceeding.
Step 2: Scope of Work Development
Based on the assessment, we develop a detailed scope of work that specifies the exact areas to be repaired by location and type of work, concrete removal methods (saw-cutting to establish clean repair boundaries, chipping to remove delaminated material to a sound substrate), rebar treatment requirements (cleaning, corrosion inhibitor application, replacement where section loss warrants), specific repair mortar products with product data sheets and applicable specifications, waterproofing system specifications where applicable, surface preparation requirements for coatings and sealers, and quality control and testing procedures. We are happy to work within owner-specified or engineer-specified scopes, or to develop the scope ourselves based on our assessment. For larger projects where an engineering firm is involved, we collaborate closely with the engineer’s requirements and specifications.
Step 3: Material Selection
Material quality is one of the most important factors in concrete repair longevity — and one of the most common places where cost-cutting contractors underdeliver. We use materials from reputable manufacturers with proven track records in the Vancouver climate, appropriate for each specific application. For repair mortars, we use cementitious polymer-modified mortars, epoxy mortars, or micro-concrete as appropriate for the depth, load exposure, and performance requirements of each repair. For corrosion protection, we apply epoxy-coated barriers or cementitious corrosion inhibitors on rebar where moisture exposure is a concern. For waterproofing membranes, we select hot-applied rubberized asphalt, liquid-applied elastomeric, or appropriate sheet systems based on the project requirements. We provide material data sheets and technical specifications with our proposals so clients and their advisors can verify the materials being used — not just the price.
Step 4: Project Execution
Our crews are experienced in the specific techniques required for quality concrete repair: saw-cutting to establish clean repair boundaries rather than chipping away at the edges (which leaves weak feather edges that fail quickly); removal of all unsound concrete to a fully sound substrate even when this means the repair area is larger than originally estimated; proper rebar treatment including wire brushing, mechanical cleaning, or abrasive blasting as specified; appropriate substrate preparation for the repair material being used — including proper moisture conditioning, primer application, and bonding agent application; careful mixing and placement of repair mortars to manufacturer specifications; and adequate curing — often the most skipped step in the industry and essential for achieving the specified strength and durability. We coordinate all work with building management to minimize disruption to residents and maintain access where required, providing advance notice to residents, clear timelines, and a point of contact for questions during the project.
Step 5: Quality Control
Quality control does not happen by accident. Our QC process includes pre-pour substrate inspection to verify all preparation requirements are met before mortar is placed, material batch tracking to ensure materials are within shelf life and mixed to specification, curing verification and documentation, post-repair hammer sounding to verify sound bond of new repairs, flood testing of waterproofed areas where specified, and photo documentation of key process steps — substrate condition, rebar treatment, material placement — so clients have a clear record of what was done and why.
Step 6: Warranty and Follow-Up
We stand behind our work with a written warranty that clearly specifies coverage terms and the claims process. Our warranty covers defects in workmanship and, where applicable, material failures. We are transparent about what is and is not covered — exclusions for normal wear, owner-caused damage, or pre-existing conditions not included in the repair scope are clearly stated. After project completion, we are available to answer questions, provide documentation for your building records, and return for warranty assessments if any concerns arise. Many of our clients are strata councils and property management firms who engage us on a recurring basis — that ongoing relationship is important to us, and it starts with doing the job right the first time.
