Waterproofing Course

Lesson 1 • Waterproofing System Categories

Introduces negative-side, positive-side, and integral waterproofing approaches. Provides a classification framework referenced in every subsequent chapter.

Lesson 2 • Water Behaviour and Building Science

Covers hydrostatic pressure, capillary action, and vapour drive as moisture forces. Connects physical principles to real-world intrusion patterns professionals must address.

Lesson 3 • Common Causes of Water Intrusion

Identifies design flaws, material failures, and installation errors that allow moisture entry. Builds diagnostic thinking used throughout the course.

Lesson 4 • Regulatory and Standards Overview

Surveys performance standards, building codes, and warranty requirements governing waterproofing work. Establishes compliance awareness applied throughout the course.

Lesson 1 • Substrate Condition Evaluation

Assesses surface soundness, contamination, and existing coatings that affect adhesion. Connects substrate condition to preparation requirements in the next chapter.

Lesson 2 • Site Assessment Reporting

Structures findings into professional reports with photos, measurements, and recommendations. Provides the documentation baseline for project planning and client communication.

Lesson 3 • Moisture Measurement Tools

Covers pin-type meters, non-invasive scanners, and relative humidity probes for quantifying moisture. Accurate readings prevent premature application failures.

Lesson 4 • Visual Inspection Techniques

Teaches structured observation of staining, efflorescence, cracks, and drainage patterns. Forms the first step in every site assessment workflow.

Lesson 1 • Cleaning and Contamination Removal

Covers pressure washing, chemical cleaning, and degreasing to remove oils, salts, and biological growth. Clean surfaces are the prerequisite for all subsequent preparation steps.

Lesson 2 • Mechanical Preparation Techniques

Teaches grinding, shot blasting, scarifying, and wire brushing to achieve required surface profiles. Mechanical methods produce the most reliable adhesion for membrane systems.

Lesson 3 • Preparation Quality Control

Establishes inspection checkpoints for cleanliness, profile, moisture content, and primer cure. Quality gates at this stage prevent costly failures after membrane installation.

Lesson 4 • Priming and Surface Conditioning

Explains primer selection, application rates, and drying requirements for different substrates. Primers promote adhesion and seal porous surfaces before membrane installation.

Lesson 1 • Liquid Membrane Material Science

Compares chemistry, elongation, and permeability of polyurethane, acrylic, and bituminous systems. Material knowledge drives correct product selection for each application scenario.

Lesson 2 • Curing and Environmental Conditions

Explains temperature, humidity, and UV exposure effects on cure time and final membrane performance. Environmental control prevents adhesion loss and surface defects.

Lesson 3 • Application Tools and Equipment

Covers rollers, brushes, squeegees, and spray equipment used for liquid membrane application. Correct tool selection directly affects film uniformity and coverage rates.

Lesson 4 • Film Thickness and Coverage Control

Teaches wet-film gauge use, coverage calculation, and multi-coat scheduling to achieve specified dry-film thickness. Insufficient thickness is the most common liquid membrane defect.

Lesson 1 • Self-Adhered Membrane Installation

Covers surface priming, release liner removal, and roller consolidation for self-adhered sheets. Proper technique eliminates air pockets and ensures full-surface bond.

Lesson 2 • Sheet Membrane Types and Selection

Compares modified bitumen, HDPE, TPO, and self-adhered rubberised asphalt membranes. Selection criteria include substrate type, exposure, and project performance requirements.

Lesson 3 • Torch-Applied Membrane Installation

Teaches torch flame adjustment, membrane heating, and lap welding for modified bitumen systems. Torch work requires precise heat control to avoid substrate damage or membrane burn-through.

Lesson 4 • Seam and Lap Quality Assurance

Establishes minimum lap widths, seam probing, and peel-test protocols for all sheet membrane types. Seam integrity is the most critical performance factor in sheet systems.

Lesson 1 • Foundation Waterproofing Systems

Covers crystalline, sheet, and liquid systems rated for below-grade positive-side application. System selection depends on hydrostatic head, substrate condition, and access constraints.

Lesson 2 • Below-Grade Moisture Challenges

Examines hydrostatic pressure, soil moisture, and seasonal water table fluctuation unique to below-grade environments. These conditions demand more robust systems than above-grade applications.

Lesson 3 • Negative-Side Waterproofing Methods

Addresses hydraulic cement, crystalline slurry, and injection grouting applied from the interior. Negative-side methods are used when exterior access is unavailable.

Lesson 4 • Drainage Board and Protection Layer

Explains dimple mat, drainage composite, and rigid insulation as protection and drainage layers over membranes. These layers prevent membrane damage during backfill and manage groundwater.

Lesson 1 • Roof and Deck Assembly Components

Identifies structural deck, vapour retarder, insulation, membrane, and protection layers in a complete assembly. Understanding the full stack prevents component incompatibility and thermal bridging.

Lesson 2 • Slope and Drainage Design

Covers minimum slope requirements, drain placement, and tapered insulation for positive drainage. Ponding water accelerates membrane degradation and must be eliminated by design.

Lesson 3 • Traffic-Bearing Deck Coatings

Addresses pedestrian and vehicular traffic coatings with wear layers, slip resistance, and crack-bridging capability. Traffic coatings must balance waterproofing performance with durability.

Lesson 4 • Roof Penetrations and Edge Details

Covers pipe boots, HVAC curbs, parapet walls, and edge metal integration specific to roof assemblies. Penetrations and edges are the highest-risk locations for roof membrane failure.

Lesson 1 • Closeout Documentation and Handover

Compiles as-built drawings, test reports, material data sheets, and warranty submissions into a handover package. Complete documentation protects all parties and enables future maintenance.

Lesson 2 • In-Process Inspection Protocols

Establishes hold points, witness tests, and daily inspection logs during installation. Catching defects during installation is far less costly than post-installation remediation.

Lesson 3 • Electronic Leak Detection

Introduces low-voltage and high-voltage ELD methods for pinpointing membrane breaches without water. ELD is essential for membranes under pavers, ballast, or green roof assemblies.

Lesson 4 • Repair and Remediation Procedures

Addresses patch material selection, surface preparation, and repair verification for each membrane type. Correct repair technique restores full system performance and warranty coverage.
