Concrete Structures: Protective Treatments and Waterproofing Course

Lesson 1 • Water Transport Mechanisms in Concrete

Covers capillary absorption, vapour diffusion, and hydrostatic pressure-driven flow. Each mechanism demands a different protective strategy.

Lesson 2 • Concrete Quality and Permeability Ratings

Introduces permeability classification systems and mix design parameters that govern durability. Establishes baseline metrics used throughout the course.

Lesson 3 • Deterioration Pathways from Moisture

Maps corrosion, freeze-thaw cycling, alkali-silica reaction, and carbonation as moisture-driven failures. Connects each pathway to measurable structural damage.

Lesson 1 • Condition Report and Treatment Planning

Synthesises inspection data into a structured condition report with prioritised treatment recommendations. Bridges assessment findings to specification decisions.

Lesson 2 • Visual Inspection Techniques

Trains structured observation of cracks, staining, efflorescence, and delamination. Visual data forms the first layer of any condition report.

Lesson 3 • Non-Destructive Testing Methods

Covers hammer sounding, rebound hammer, ground-penetrating radar, and half-cell potential testing. Each method reveals subsurface conditions without damaging the structure.

Lesson 1 • Mechanical Preparation Methods

Covers shot blasting, scarifying, grinding, and high-pressure water jetting. Mechanical methods remove laitance, coatings, and contamination efficiently.

Lesson 2 • Preparation Standards and Profiles

Introduces surface profile scales and cleanliness standards used industry-wide. Matching profile to product requirements prevents adhesion failure.

Lesson 3 • Quality Verification Before Application

Confirms surface readiness through pull-off adhesion tests, pH checks, and moisture verification. Verification prevents costly rework after treatment application.

Lesson 4 • Crack and Defect Repair Before Treatment

Addresses routing, filling, and bridging of cracks prior to coating or waterproofing. Unrepaired defects propagate through any applied treatment layer.

Lesson 1 • Silane and Siloxane Application

Covers application rates, methods, and environmental conditions for silane and siloxane products. Correct application ensures full penetration and long-term hydrophobic performance.

Lesson 2 • Chemistry of Penetrating Sealers

Explains silane, siloxane, and silicate reaction chemistry within the concrete matrix. Chemical understanding guides correct product selection for substrate conditions.

Lesson 3 • Performance Limits and Suitable Applications

Defines where penetrating treatments succeed and where they are insufficient. Matching treatment type to exposure class prevents premature failure.

Lesson 1 • Crystalline Waterproofing Mechanisms

Explains how crystalline compounds migrate and self-seal within the concrete pore network. This self-sealing property makes crystalline systems uniquely durable under sustained moisture.

Lesson 2 • Cementitious Coating Types and Properties

Distinguishes rigid, flexible, and polymer-modified cementitious coatings by composition and performance. Product selection depends on substrate movement and hydrostatic exposure.

Lesson 3 • Quality Control and Acceptance Testing

Establishes thickness verification, adhesion testing, and flood testing protocols for cementitious systems. Acceptance criteria must be defined before work begins.

Lesson 4 • Application of Cementitious Systems

Covers mixing, priming, brush and spray application, and curing of cementitious waterproofing. Correct application sequence is critical to achieving rated hydrostatic resistance.

Lesson 1 • Sheet Membrane Installation

Applies torch-on, self-adhesive, and mechanically fastened sheet membranes with correct lap and seam procedures. Seam integrity is the most common failure point in sheet systems.

Lesson 2 • Membrane System Types and Selection

Compares bituminous, thermoplastic, EPDM, and liquid-applied membranes by performance and application. Selection criteria include exposure, movement, and overburden conditions.

Lesson 3 • Protection, Drainage, and Overburden

Installs protection board, drainage composites, and insulation over completed membranes. Overburden systems protect membranes from mechanical damage and manage water away from the structure.

Lesson 4 • Liquid-Applied Membrane Application

Covers polyurethane, PMMA, and elastomeric liquid membranes from priming through topcoat. Uniform film build and reinforcement at details are critical to performance.

Lesson 1 • Application Methods and Environmental Controls

Applies coatings by airless spray, roller, and brush under controlled temperature and humidity. Environmental conditions directly affect film formation and adhesion.

Lesson 2 • Protective Coating Chemistry and Types

Distinguishes epoxy, polyurethane, acrylic, and polyurea coatings by chemistry and performance profile. Chemistry determines chemical resistance, flexibility, and UV stability.

Lesson 3 • Mixing, Thinning, and Pot Life Management

Covers two-component mixing ratios, induction time, pot life, and thinning limits. Incorrect mixing is the leading cause of coating cure failure.

Lesson 4 • Chemical and Industrial Exposure Applications

Specifies coating systems for secondary containment, food-processing floors, and wastewater structures. Each environment requires validated chemical resistance and regulatory compliance.

Lesson 1 • Failure Analysis and Remediation

Diagnoses blistering, delamination, cracking, and pinholing in applied treatments and identifies root causes. Correct diagnosis prevents recurrence after remediation.

Lesson 2 • Leak Detection and Integrity Testing

Applies flood testing, electric field vector mapping, and tracer gas methods to locate membrane breaches. Early leak detection limits damage and repair costs.

Lesson 3 • Planned Maintenance Programmes

Designs inspection schedules, cleaning regimens, and reapplication cycles for each treatment type. Planned maintenance extends service life and reduces lifecycle costs.

Lesson 4 • Performance Reporting and Asset Management

Integrates treatment performance data into asset management systems and lifecycle cost models. Data-driven reporting supports capital planning and treatment renewal decisions.
