About Waterproofing
Protect Your Home from Water Damage. How Does it Work?
Step 01 - COMPREHENSIVE INSPECTION & LEAK DETECTION
Effective waterproofing starts with diagnosing the true source of the problem. Lee personally conducts a thorough inspection of your basement, foundation walls, patio, or roof structure. We look beyond visible damp patches to identify the root cause—whether it's poorly graded soil, hydrostatic groundwater pressure, hairline foundation cracks, or failing external membranes. This detailed investigation ensures we don't just treat the symptoms; we permanently eliminate the source of water intrusion.
Step 02 - MOISTURE ELIMINATION & SURFACE PREPARATION
Before we apply a single drop of sealant, every surface must be completely clean and dry. Planet Painting uses industrial-grade pressure washing equipment and specialized mold-killing detergents to strip away dirt, algae, and organic growth. We also use grinding tools to mechanically open up narrow hairline cracks, preparing them to receive deep-penetrating injections. We then ensure the area is thoroughly dried out using powerful ventilation fans if needed, guaranteeing the sealant bonds directly to the concrete, stone, or masonry.
Step 03 - CRACK INJECTION & PRIMARY SEALING
For active leaks or structural cracks in foundation walls, Lee and our crew utilize professional high-pressure epoxy and polyurethane injection systems. This technique pushes the sealant deep into the crack, filling it completely from the inside out and creating a permanent, flexible waterproof bond. For larger surfaces, we apply heavy-duty, elastomeric liquid membranes or cementitious coatings that form an impenetrable, waterproof barrier against lateral moisture and ground seepage.
Step 04 - DRAINAGE & EXTERIOR REPAIRS
Sometimes, waterproofing requires fixing the land around your property. We assess and address external factors such as clogged or broken gutters, downspouts that discharge water too close to the foundation, and improper soil grading. If needed, Planet Painting can install or repair French drains, sump pump systems, and weeping tiles to actively redirect water away from your property, ensuring hydrostatic pressure never builds up against your walls again.
Step 05 - FINAL TESTING & LONG-TERM GUARANTEE
Once our waterproofing systems are fully applied and properly cured, we perform rigorous final testing. We simulate heavy rain events and conduct water flood tests on flat surfaces to ensure there is zero seepage or pooling. Lee walks through the entire installation with you, explaining our solutions. We back our premium waterproofing materials and professional installation with a comprehensive workmanship guarantee, giving you absolute peace of mind that your property will remain permanently bone-dry.

Waterproofing Solutions We Use
While our sealants may not offer a rainbow of hundreds of bright shades, Planet Painting provides access to a wide spectrum of professional-grade waterproofing materials carefully selected for their specific application. From deep-penetrating silicate crystallizers that seal concrete from the inside out to heavy-duty, rubberized elastomeric membranes designed to bridge expanding cracks, we have the right formulation for every surface, including foundations, flat roofs, patios, and basement walls.
Choosing the right waterproofing solution is about more than just color—it is about performance, thickness, and climate resistance. Lee personally guides you in selecting between trowel-applied cementitious coatings, fast-curing liquid polyurethanes, or clear penetrating silanes and siloxanes. We match the specific product to your exact moisture level and structural needs, ensuring you walk away with a durable, permanent, and perfectly tailored defense against water intrusion.
Materials
Materials & Tools
When it comes to waterproofing, the final appearance of a sealant can change drastically depending on the surface it is applied to, making real-world testing essential. That is why Lee brings actual physical samples of our waterproofing membranes, clear penetrating silanes, and tinted coatings directly to your property. We apply these test swatches side-by-side against your existing brickwork, raw concrete, or roof tiles, allowing you to see exactly how the product interacts with the unique texture, porosity, and existing colour of your materials before any permanent application begins.
While waterproofing products prioritise invisible protection over a vast palette of vibrant shades, we work with a specialised range of clear finishes, neutral tones, and subtle tints (including various greys, tans, and blacks) designed to blend seamlessly with your property. Testing these options on-site in natural daylight helps us assess not just the final aesthetic, but also how the product cures on your specific surface. With Lee’s expert guidance, you will confidently select a waterproofing solution that offers complete, permanent protection while subtly complementing the natural beauty of your home or business.
