Books and Resources to Start Strong
Before you invest in equipment, you need to understand the business fundamentals of basement waterproofing. These books will teach you the technical knowledge, business operations, and sales strategies that successful basement waterproofing contractors use to build profitable companies.
Residential Waterproofing: Durability, Functionality, and Aesthetics by Peter Sjöstrom and Magne Helland-Hansen
This book covers the science and methods behind waterproofing systems—both interior and exterior solutions. You’ll learn how water moves, where it penetrates, and why certain techniques fail. Understanding the technical side makes you credible with customers and helps you diagnose problems correctly.
The Basement Survival Manual by Dan Kolars
This practical guide focuses specifically on basement issues and solutions. It covers foundation problems, moisture control, and repair techniques in straightforward language. For a basement waterproofing startup, this is one of the most directly applicable resources you can own.
The Contractor’s Legal Kit by Daniel Ambrosio
You’ll need contracts, liability waivers, and proper business structure from day one. This book provides templates and guidance on protecting yourself legally. Waterproofing work carries risk—having proper contracts in place saves you thousands if something goes wrong.
Running a Contracting Business by David Jobson
This book covers scheduling, estimating, pricing, and managing crew labor—all critical to a contracting business. You’ll learn how to bid jobs profitably and organize your operations so you can scale beyond just doing the work yourself.
Equipment You Need
Basement waterproofing requires specific tools and materials depending on the methods you offer. You don’t need everything at once, but you’ll need quality equipment that performs in damp, confined spaces. Below is what separates professional contractors from DIYers.
Diagnostic and Inspection Tools
- Moisture meter: Detects water and dampness in walls and concrete. Essential for identifying problem areas before recommending solutions.
- Thermal imaging camera: Shows cold spots where water infiltrates or air leaks. Helps you see problems customers can’t.
- Borescope or inspection camera: Looks inside cracks, joints, and small spaces without breaking walls open.
- Flashlight and headlamp: Basements are dark. Get powerful LED lights that mount on your head or body so your hands stay free.
- Measuring tape and level: Standard tools for assessing foundation slope, crack size, and wall alignment.

Crack Repair and Sealant Application
- Caulking guns: For applying polyurethane sealants, silicone, and epoxy. Get both standard and powered versions for high-volume jobs.
- Chisel set and pry bars: Remove old sealant, open cracks wider for better filler penetration, and remove debris from joints.
- Grinder or rotary tool: Cleans cracks and prepares surfaces for sealants. A 4.5-inch angle grinder handles most basement crack work.
- Wire brush and cleaning tools: Remove loose concrete, old sealant, and dust from cracks before applying new material.
- Injection ports and epoxy injector: For high-pressure crack injection systems. Allows you to seal cracks from the inside out.

Waterproofing Membranes and Sealants
- Polyurethane sealants: Flexible, long-lasting, and adheres to wet or damp surfaces. Industry standard for foundation cracks.
- Epoxy injection systems: For structural crack repair where you need permanent bonding.
- Liquid waterproofing coatings: Painted or sprayed on interior walls to create a moisture barrier.
- Basement paint and primer: Moisture-rated products designed for damp basements and concrete surfaces.
- Hydraulic cement: Fast-setting repair material for quick patches and emergency water entry points.

Drainage and Interior Solutions
- Sump pump (submersible and pedestal types): For interior basement drainage systems. Have options for different pit depths and water volumes.
- Drain tile and perforated pipe: PVC pipe for routing water toward sump pits and away from foundation.
- Dehumidifier (commercial-grade): Controls moisture and prevents mold in finished basements. 40-70 pint capacity for typical basement sizes.
- Vapor barrier plastic sheeting: 6-mil polyethylene for basement floors and walls to block ground moisture.
Safety and Protection Gear
- Respirator or N95 masks: Concrete dust, mold spores, and chemical fumes require respiratory protection.
- Safety glasses and goggles: Protect eyes from grinding debris, sealant spray, and dust.
- Work gloves (nitrile and heavy-duty): Thin gloves for handling sealants, thicker ones for rough concrete and sharp edges.
- Steel-toed boots and knee pads: Basements are wet and unforgiving. Proper footwear prevents injury.
- First aid kit and eyewash station: Chemical exposure is possible—have supplies to rinse and treat minor injuries quickly.
Measuring and Documentation
- Smartphone or digital camera: Document all jobs before, during, and after. Photo evidence protects you and satisfies customers.
- Moisture meter with data logging: Records readings over time to show humidity trends.
- Notebooks and forms: Paper-based or digital job tracking for estimates, inspections, and follow-ups.
What to Buy First vs Later
You don’t need to stock every tool and material before your first job. Start lean, add equipment as jobs demand it, and invest in quality where it matters most.
- First (before your first job): Moisture meter, basic hand tools, caulking guns, safety gear, polyurethane sealant, concrete cleaner, headlamp, and measuring tape. Budget roughly $800–$1,200 for these.
- After your first 3–5 jobs: Angle grinder, injection system equipment, commercial dehumidifier, and sump pump options. Add these as customers request specific solutions.
- Later (after 10+ jobs): Thermal imaging camera, borescope, epoxy injection equipment, and commercial-grade coating applicators. These tools pay for themselves when you handle premium or specialized work.
New vs Used Equipment
Where you buy matters. Diagnostic tools, safety equipment, and sealants must be new and reliable—you can’t risk using a faulty moisture meter or expired sealant. Savings aren’t worth the liability. However, some items can be sourced used without compromising quality.
Buy new: All diagnostic tools (moisture meters, thermal cameras, borescopes), sealants and adhesives, safety equipment, and dehumidifiers. These directly affect your credibility and customer outcomes. Used versions may be calibrated incorrectly or degraded. Can buy used: Hand tools, ladders, caulking guns, some power tools, and storage equipment. Check function carefully and replace anything with visible damage. Used grinders and sanders work fine if the motor runs smoothly. Avoid used respirators or safety gear—this is personal protective equipment that you can’t verify the history of.
Where to Buy
- Home Depot and Lowe’s: Quick access to sealants, safety gear, basic tools, and cleaning supplies. Good for learning product brands available in your area.
- Grainger: Industrial-grade tools and equipment. Better selection than box stores and faster shipping for contractors.
- Concrete and masonry suppliers: Local suppliers carry waterproofing membranes, epoxy systems, and specialty sealants contractors use. Build relationships here.
- Waterproofing-specific distributors: Companies like Xypex, Basement Systems, and Sika sell direct to contractors. Prices and selection are better than retail stores.
- eBay and Facebook Marketplace: For used hand tools and equipment. Meet in person, test the item, and only buy if satisfied with condition.
- Pawn shops and tool rental outlets: Source used power tools at 40–60% of retail. Quality varies, so inspect thoroughly before buying.
