A Repair Should Not Begin With a Trowel
One of the most overlooked aspects of structural repair is planning the work before execution begins.
A contractor may have:
The repair material
Skilled workers
Mixing equipment
Tools
Yet the repair can still go wrong if nobody has clearly documented:
What is being repaired?
Why is it being repaired?
How will it be repaired?
What materials will be used?
What quality checks are required?
This is where a Structural Repair Method Statement becomes important.
What Is a Method Statement?
A method statement is a documented procedure describing how a particular construction or repair activity is intended to be carried out safely and in accordance with the approved project requirements.
For structural repair, it can provide a common reference for:
Site engineers
Contractors
Applicators
QA/QC personnel
Consultants
Project managers
It helps convert an engineering requirement into a controlled site execution process.
The Guardian's Principle
"If the repair method exists only in someone's head, it is difficult to control, inspect or reproduce."
A properly prepared method statement creates a common understanding before work begins.
1. Define the Scope of Repair
The first section should clearly establish:
Structure / building
Structural element
Location
Type of deterioration
Approximate repair area
Repair objective
For example:
RCC column — concrete spalling and localized section loss — rehabilitation according to approved structural repair design.
The scope should be specific enough that the site team understands exactly what work is covered.
2. Describe the Existing Condition
The method statement should explain the condition that led to the repair.
This may include:
Spalling
Honeycombing
Cracking
Exposed reinforcement
Concrete deterioration
Localized section loss
Where relevant, supporting inspection records, photographs or test reports may form part of the project documentation.
3. Establish the Repair Methodology
This is the heart of the document.
It should explain the sequence of work.
A typical sequence might be:
1. Identify & Mark
Define the repair zone.
↓
2. Remove Unsound Concrete
Expose suitable sound substrate.
↓
3. Inspect Reinforcement
Assess exposed reinforcement and follow the approved treatment.
↓
4. Prepare Substrate
Clean and prepare according to the repair system.
↓
5. Install Formwork / Reinforcement
Where required by the repair design.
↓
6. Mix Repair Material
Follow the manufacturer's specified procedure.
↓
7. Place Repair Material
Use the approved placement method.
↓
8. Cure
Follow the specified curing procedure.
↓
9. Inspect
Record the completed repair.
4. Identify the Materials
The method statement should identify the materials being used.
Depending on the repair system, this could include:
Repair mortar
Micro Concrete
Bonding system
Reinforcement treatment system
Formwork materials
Curing materials
The product should be identified by its actual approved product name and specification.
Avoid vague descriptions such as:
"Use good-quality repair material."
A professional document should identify exactly what has been approved.
5. Reference the Technical Data Sheet
The method statement should not replace the product Technical Data Sheet.
It should work together with it.
Important product-specific information may include:
Mixing procedure
Water requirement
Application thickness
Working time
Placement method
Curing requirements
Storage conditions
Applicable limitations
The manufacturer's current Technical Data Sheet should always be treated as the controlling reference for product-specific application requirements.
6. Explain Surface Preparation
Surface preparation should be described clearly.
Depending on the approved repair system, the process may include:
Removing unsound concrete
Cleaning the substrate
Removing dust and loose particles
Preparing exposed reinforcement
Achieving the specified substrate condition
The objective is to establish the appropriate interface for the repair system.
7. Define the Mixing Procedure
A good method statement should remove guesswork.
It should identify:
Material → Equipment → Water → Mixing Sequence → Mixing Time → Placement
The exact parameters must come from the approved product documentation.
Never write:
"Add water as required."
That creates uncontrolled variation.
Instead, specify the manufacturer's approved mixing procedure.
8. Define the Placement Procedure
The document should explain:
Where placement starts
How material will reach the repair zone
Whether formwork is required
How the repair zone will be filled
How interruptions will be handled
How reinforcement congestion will be addressed
For flowable Micro Concrete applications, placement planning becomes particularly important where the repair geometry is deep or confined.
9. Include Curing Requirements
Curing should be a specific section—not an afterthought.
The method statement should identify the curing procedure appropriate to the approved product and project conditions.
The repair team should know:
When curing begins → how the repair is protected → how long the required procedure continues.
10. Quality Control & Inspection
A professional method statement should establish the inspection points.
Before repair
Repair area identified
Unsound concrete removal verified
Reinforcement inspected
Substrate condition checked
Before placement
Material approved
Batch checked
Mixing equipment ready
Formwork checked
Water measurement controlled
During placement
Mixing procedure followed
Placement monitored
Formwork monitored
Repair zone adequately filled
After placement
Curing completed
Surface inspected
Defects recorded
Final acceptance documented
11. Include Responsibilities
This is often overlooked.
A method statement should make responsibilities clear.
For example:
Structural Engineer / Consultant
Design and technical approval where applicable.
Site Engineer
Execution supervision.
Contractor
Resources, manpower and execution.
QA/QC Team
Inspection, documentation and testing as specified.
Applicator
Correct execution of the approved procedure.
Clear responsibility reduces the possibility of:
"I thought someone else was checking it."
12. Safety Should Be Part of the Method Statement
Structural repair can involve:
Breaking concrete
Exposed reinforcement
Working at height
Dust
Power tools
Heavy materials
Wet cementitious materials
Restricted working areas
The project-specific safety requirements should therefore be incorporated into the approved work procedure.
13. What a Good Method Statement Should NOT Do
A method statement should not:
Invent product specifications
Override the Technical Data Sheet
Replace structural design
Give workers freedom to improvise critical parameters
Use vague instructions
Ignore site-specific conditions
The method statement is a control document, not a piece of generic marketing literature.
The Guardian's Method Statement Structure
A practical structural repair method statement can be organized as:
01 — Project & Location
02 — Scope of Work
03 — Existing Condition
04 — Repair Objective
05 — Approved Materials
06 — Equipment & Tools
07 — Surface Preparation
08 — Reinforcement Treatment
09 — Formwork / Reinforcement Installation
10 — Mixing Procedure
11 — Placement Procedure
12 — Curing
13 — Quality Control & Inspection
14 — Safety Requirements
15 — Responsibilities
16 — Records & Acceptance
This structure creates a much more disciplined repair process.
The Difference Between a Method Statement and a Product TDS
This distinction is important.
Technical Data Sheet
Answers:
"What is this product and how should this product be used?"
Method Statement
Answers:
"How will this particular project repair be executed and controlled?"
They are complementary—not interchangeable.
GUGAFIX® Micro Concrete
When GUGAFIX® Micro Concrete is specified for an appropriate repair application, the project method statement should incorporate the current product documentation and project requirements.
The formulation uses carefully selected cementitious materials, graded aggregates, admixtures and German-origin specialty polymers.
But the material is only one component of the repair system.
Design + Methodology + Material + Workmanship + QC
must work together.
The Guardian's Site Checklist
Before approving a structural repair method statement, ask:
Is the repair clearly defined?
Has the cause of deterioration been considered?
Is the structural methodology approved where required?
Are the materials clearly identified?
Is the product TDS referenced?
Is surface preparation defined?
Is the mixing procedure defined?
Is placement defined?
Is curing defined?
Are inspection points defined?
Are responsibilities clear?
Are safety requirements included?
If several answers are "No", the document isn't ready for controlled execution.
Frequently Asked Questions
Is a method statement required for every concrete repair?
Requirements vary by project and organization. For significant structural repairs, a documented method statement is an important tool for controlled execution.
Who prepares the method statement?
Typically the contractor or executing organization prepares it, subject to the project's approval process and technical requirements.
Does a method statement replace structural drawings?
No. It should work alongside the approved structural design, drawings, specifications and product documentation.
Can a contractor modify the method statement at site?
Any significant change should follow the project's change-control and approval procedure rather than being made informally.
Should the product TDS be attached to the method statement?
Where required by the project, it is good practice to reference or include the applicable current product documentation.
The Guardian's Advice
"A method statement turns a repair from an activity into a controlled process."
