Stop Water Leaks Around Basement Pipes and Form-Tie Holes

Water leaking around basement pipes or form-tie holes is a common problem in poured concrete basement walls. Often, the hole for the pipe is cut or formed larger than the pipe itself, leaving a small gap around the pipe that water can easily follow. In other cases, temporary fixes like hydraulic cement or patching compounds are applied, but they eventually loosen or crack. Leaks can also develop when old pipes are replaced or moved, breaking the original seal.

Over time, hydrostatic pressure forces water through these openings, leading to damp spots, active leaks, or standing water near the pipe. Patching from the inside with hydraulic cement or caulk rarely provides a lasting solution because these materials can’t reach deep into the wall or hold up under water pressure.

The PipeTite DIY Injection Kit provides a permanent, professional-grade fix by injecting expanding urethane foam directly into the leak path. The resin expands to fill the space between the pipe and the surrounding concrete, bonding tightly and sealing the leak from the inside out — a permanent way to stop water leaks around basement pipes.

Key Benefits of the PipeTite DIY Injection Kit

• Permanently seals active or recurring leaks around basement pipes.

• Repairs leaking form-tie holes and small voids.

• Expands to fill the entire gap for complete waterproofing.

• Bonds to wet surfaces and all common pipe materials.

• Works in wet or dry conditions.

• Easy DIY application with a standard caulking gun.

Together, these features make PipeTite a reliable, permanent solution for homeowners and professionals alike.

How to Seal Leaks Around Basement Pipes Using Low-Pressure Urethane Injection

This complete do-it-yourself injection kit permanently repairs pipe penetrations and leaking form-tie holes in poured concrete or brick walls. Using low-pressure injection, the single-component urethane resin flows into the smallest voids and reacts with water to expand forcefully — filling the entire gap between pipe and concrete.

As it cures, the foam forms a flexible, closed-cell structure that adheres tightly to wet concrete and pipe surfaces. The result is a watertight, flexible seal that prevents future seepage, even under active water pressure.

Why PipeTite Works Better Than Surface Repairs

• Expands deep inside the wall, sealing hidden voids and cracks that surface patches can’t reach.

• Bonds tightly to wet concrete and all common pipe materials, including PVC, copper, and steel.

• Permanently stops water seepage around basement pipes, conduits, and form-tie holes.

• Won’t loosen, crack, or separate like hydraulic cement or caulk.

• No excavation required — repair leaks from inside the basement using a standard caulking gun.

Ideal Applications for PipeTite Urethane Injection

• Leaks around water, sewer, or electrical service lines where they enter poured concrete basement walls.

• Rusted or leaking form-tie holes and tie-rod points in poured concrete foundations.

• Pipe penetrations through poured concrete walls where water seeps around the pipe.

• Small voids or honeycombed areas in poured concrete near utility penetrations.

(Note: Not recommended for hollow block or masonry walls — expanding foam may escape into open cores.)

What’s Included in the PipeTite DIY Injection Kit

• One cartridge of expanding urethane foam (single-component, water-reactive).

• Surface sealer jars for mounting injection ports and containing the resin.

• Injection ports and accessories for controlled delivery.

• Step-by-step instructions for a professional-grade waterproofing repair.

All you need is a standard caulking gun — no special tools or prior experience required.

Permanent Results Using Professional Injection Technology

Once cured, the injected foam forms a dense, flexible barrier that blocks groundwater from entering through pipe openings, form-tie voids, or small cracks near penetrations. This is the same urethane injection method used by professional waterproofing contractors — now made simple for homeowners as a reliable DIY repair system.

Seal Basement Pipe Leaks and Form-Tie Holes from the Inside

Surface patches, caulks, or hydraulic cement only provide temporary relief — they can’t reach the leak path inside the wall. Urethane injection seals the source of the problem and stays flexible to accommodate minor movement or temperature changes. It’s the proven professional method — now available in an easy, affordable DIY kit.
