SealBoss ® 1510 Water Stop Foam Ceiling Crack Leak Repair

Job Walk Shopping Mall Los Angeles

A concrete crack in the concrete ceiling in a busy shopping mall was actively leaking. Cracks were described as fine and hairline. A two‑person crew mobilised with SealBoss 1510 Water Stop Foam and SealBoss Packer Evolution 13‑100 AL ports performed a hydroactive polyurethane injection during the designated maintenance window.

Following the repair, a job walk was conducted to inspect the injection site. Correct packer placement was observed and it was, verified that foam had fully expanded, and confirmed that the ceiling was completely dry before reopening the area for traffic.

Injection Procedure

After tracing the crack, technicians marked drill points and hole were drilled at an approximately 45‑degree angle to intersect the crack mid‑depth, then fitted with SealBoss 13‑100 AL packers.

Working from the end showing the strongest water flow, the crew pressurised SealBoss 1510 with the injection pump at up to over 1,000 psi. Resin disappeared into the concrete and re‑emerged at the next packer, or beyond, confirming full penetration. After completing the first pass, they paused to allow the foam to expand, then repeated the sequence. Selected ports accepted a third shot to ensure a dense seal.

SealBoss Guideline Leak Seal Injection

Guideline - Leak Sealing Injection

This jobsite picture depicts one of the more challenging overhead leak sealing injection applications in a confined space with limited resources, very active water leaks and standing water in the structure. The contractor is using a button-head packer set-up for a secure and leak free connection of the hose to the injection packer. On the ceiling of the structure you can see previous injection points and cured foam that formed around the injected cracks while expanding and creating a compression seal. The contractor is covered in impervious protective clothing to protect himself from water and liquid product during the injection process. It is during jobs like this, when you appreciate a complete injection system that is proven, reliable and durable.

This is our compact guideline to waterproofing and leak sealing injection. From choosing product and equipment to job prep and the injection procedure itself, we cover many important product features and provide valuable information to assist you in making your application a successful one.
