Slab Waterproofing Course

Lesson 1 • Concrete Slab Anatomy

Covers the structural layers and components of cast-in-place and precast slabs. Understanding slab composition is prerequisite to selecting compatible waterproofing systems.

Lesson 2 • Waterproofing System Categories

Introduces the major families of waterproofing systems used on slabs. Students gain a classification framework used throughout the entire course.

Lesson 3 • Water Intrusion and Slab Damage

Explains how water penetrates concrete slabs and triggers deterioration mechanisms. Establishes the problem context that justifies all subsequent waterproofing interventions.

Lesson 1 • Crack and Joint Repair Before Waterproofing

Addresses repair of active and dormant cracks and joint preparation prior to membrane application. Unrepaired defects telegraph through membranes and cause premature failure.

Lesson 2 • Mechanical Surface Preparation Methods

Trains students on shot blasting, scarifying, grinding, and diamond grinding equipment. Each method produces a specific profile and suits different slab conditions.

Lesson 3 • Pre-Application Site Inspection

Teaches systematic inspection of slab surfaces before any waterproofing work begins. Identifies defects that must be remediated to ensure membrane adhesion and performance.

Lesson 4 • Moisture Mitigation Strategies

Covers methods to reduce substrate moisture to acceptable levels before membrane installation. Excess moisture is the leading cause of adhesive membrane failure.

Lesson 1 • Sheet Membrane Types and Selection

Compares modified bitumen, HDPE, TPO, and EPDM sheet membranes for slab applications. Selection criteria include exposure, traffic, and compatibility with overburden.

Lesson 2 • Torch-Applied Membrane Installation

Trains safe torch application of modified bitumen membranes including flame control and adhesion verification. Torch work requires strict fire safety and heat management discipline.

Lesson 3 • Seam Testing and Quality Control

Covers destructive and non-destructive seam testing methods and documentation requirements. Verified seams are the primary defense against water infiltration at membrane joints.

Lesson 4 • Primer Application for Sheet Membranes

Covers primer types, application rates, and flash-off times required before sheet membrane installation. Correct priming is mandatory for full-bond and partial-bond systems.

Lesson 1 • Application Methods and Thickness Control

Trains squeegee, roller, and spray application techniques with wet-film thickness gauging. Consistent thickness across the entire slab surface is critical to uniform performance.

Lesson 2 • Cure Monitoring and Protection

Covers cure time verification, environmental condition limits, and temporary protection of freshly applied membranes. Premature traffic or rain exposure destroys uncured liquid membranes.

Lesson 3 • Liquid Membrane Chemistry and Types

Explains the chemistry of one- and two-component liquid membranes and how cure mechanisms affect performance. Chemistry knowledge guides product selection for specific exposure conditions.

Lesson 4 • Mixing and Pot Life Management

Covers accurate mixing ratios, mechanical mixing procedures, and pot life monitoring for two-component systems. Incorrect mixing ratios produce under-cured membranes with no waterproofing value.

Lesson 1 • Curing and Performance Verification

Addresses wet curing requirements for cementitious and crystalline systems and field performance tests. Inadequate curing prevents full crystal development and reduces long-term effectiveness.

Lesson 2 • Integral Crystalline Admixture Installation

Covers batching crystalline admixtures into fresh concrete at the plant or on-site. Proper dosing and mixing ensure uniform crystal distribution throughout the slab.

Lesson 3 • Crystalline Waterproofing Mechanism

Covers how crystalline admixtures and surface treatments react with water to form insoluble crystals that block capillary pores. This self-sealing property distinguishes crystalline from film-forming systems.

Lesson 4 • Mixing and Applying Cementitious Coatings

Step-by-step mixing and brush or spray application of two-component cementitious coatings. Correct water-to-powder ratio and wet substrate conditions are mandatory for adhesion.

Lesson 1 • Pipe and Conduit Penetration Sealing

Trains installation of pipe boots, clamping flanges, and liquid-applied collars around penetrations. Each penetration type requires a specific detail to handle differential movement.

Lesson 2 • Drain Body Integration

Covers clamping ring drains, sheet-flashing drains, and retrofit drain inserts for waterproofed slabs. Drain-to-membrane connection is a critical detail that must be watertight and serviceable.

Lesson 3 • Expansion Joint Waterproofing Systems

Covers preformed expansion joint covers, hybrid seals, and flexible membrane bridges for moving joints. Joint systems must accommodate cyclic movement without fatigue failure.

Lesson 4 • Construction and Control Joint Sealing

Addresses sealing of construction joints and saw-cut control joints with backer rod and sealant. Proper joint geometry and sealant selection prevent adhesion failure under cyclic stress.

Lesson 1 • Insulation in Inverted Roof Assemblies

Covers the inverted or protected membrane assembly where insulation sits above the waterproofing layer. This configuration protects the membrane from thermal cycling and UV degradation.

Lesson 2 • Drainage Composite Systems

Explains geocomposite drainage mats that manage water above the membrane and direct it to drains. Proper drainage prevents hydrostatic buildup that can lift or degrade membranes.

Lesson 3 • Protection Board Selection and Installation

Covers rigid and semi-rigid protection boards that shield membranes from puncture during overburden placement. Board selection depends on membrane type, traffic load, and overburden depth.

Lesson 4 • Plaza Deck and Podium Assembly Design

Integrates membrane, drainage, insulation, and finish layers into a complete plaza or podium deck assembly. Students sequence layers correctly and coordinate with structural load limits.

Lesson 1 • Flood Testing Procedures

Trains the setup, monitoring, and documentation of flood tests for horizontal waterproofed slabs. Flood testing is the most definitive proof of system integrity before overburden is placed.

Lesson 2 • Documentation and Warranty Compliance

Covers the records, photos, and test reports required to support manufacturer and contractor warranties. Complete documentation protects all parties and enables future diagnostic investigations.

Lesson 3 • Pre-Installation Quality Checks

Establishes the inspection checklist for substrate, materials, and environmental conditions before work begins. Catching deficiencies before application prevents costly remediation after the fact.

Lesson 4 • In-Process Inspection Techniques

Covers wet-film thickness checks, seam probing, and visual inspection during active installation. Continuous in-process monitoring catches defects before they are buried under overburden.
