INJECTION SUITABILITY

When Concrete Crack Injection Makes Sense

A crack can become a pathway for water when it extends through a concrete wall or structural assembly. Injection may be appropriate when the crack is accessible, the surrounding concrete remains serviceable, and the water-entry path can be identified.

Lewes properties include crawl-space homes, older foundations, multifamily buildings, and commercial structures. Each crack needs to be evaluated based on its movement, width, water activity, location, previous repairs, and surrounding material.

When water is entering through a wall-to-floor joint, penetration, multiple cracks, or a broader below-grade condition, foundation leak repair may require a different approach.

Injection may be considered when:

  • An isolated crack is visibly leaking

  • The crack is accessible from the interior

  • The surrounding concrete remains in serviceable condition

  • Water is following a traceable crack pathway

  • Previous surface patches have not reached the full crack

  • The condition does not show major displacement or deterioration

PRESSURE-INJECTION PROCESS

How the KIP Pressure-Injection Process Works

Platinum Roofs uses the KIP pressure-injection process for eligible leaking concrete cracks, including suitable cracks as small as .002 inches.

The goal is to place compatible repair material into the crack and water pathway rather than covering only the visible surface. The exact setup depends on the crack, concrete, access, and water conditions.

Injection points are positioned along the affected area, and material is introduced under controlled pressure so it can move through the crack. The process may include:

  • Inspecting the crack and surrounding concrete

  • Preparing the surface and injection area

  • Placing injection points along the crack

  • Introducing compatible material under controlled pressure

  • Monitoring material movement through the crack

  • Completing a final review of the treated area

SELECTING THE RIGHT REPAIR

When Injection Is Not the Right Repair

Concrete crack injection is a targeted repair, but it is not appropriate for every water-intrusion problem. A visible crack may be only one part of a larger condition involving joints, deteriorated concrete, masonry, structural movement, drainage, or multiple water pathways.

When the surrounding assembly is moving, displaced, deteriorated, or leaking through several areas, broader structural leak repair or a complete leak-remediation assessment may be needed.

Injection may not be the right direction when:

  • The crack shows ongoing movement or displacement

  • Concrete or masonry around the crack is deteriorated

  • Water is entering through several joints or penetrations

  • The source is plumbing, drainage, condensation, or roofing

  • Previous repairs prevent proper access to the crack

  • The problem involves a larger structural assembly

Frequently Asked Questions

What is concrete crack injection?

Concrete crack injection places compatible repair material into an eligible crack under controlled pressure. The goal is to fill the pathway within the concrete rather than covering only the visible surface.

What is the KIP crack-injection system?

The KIP system is a pressure-injection process used for eligible leaking concrete cracks. Platinum Roofs can use the process on suitable cracks as small as .002 inches, depending on the crack, concrete, access, and water conditions.

Can an actively leaking concrete crack be injected?

Some active cracks can be treated through pressure injection. Suitability depends on the crack size, movement, concrete condition, access, water activity, and condition of the surrounding structure.

Can every concrete crack be repaired with injection?

No. Cracks showing continued movement, displacement, widespread deterioration, inaccessible pathways, or broader structural problems may require another repair method.

Is crack injection better than surface patching?

Injection and surface patching serve different purposes. A surface patch treats the visible face of the crack, while pressure injection is intended to place material within an eligible crack. The correct method depends on the source and condition.

Does concrete crack injection strengthen the structure?

Some injection materials may contribute to restoring continuity within a crack, while others are primarily intended to stop water movement. Structural concerns should be evaluated separately before assuming injection will restore the affected assembly.

Can crack injection be used in crawl spaces and commercial properties?

Yes. Platinum Roofs provides concrete crack injection for eligible cracks in homes, crawl spaces, multifamily buildings, businesses, and commercial structures.

How long does a concrete crack-injection repair last?

Service life depends on the crack, movement, surrounding concrete, water pressure, material used, and whether other contributing conditions remain. Platinum Roofs evaluates these factors before recommending injection.

How do I request a concrete crack-injection assessment?

Request an assessment online or call Platinum Roofs at (302) 226-4510. Share where the crack is located, whether it actively leaks, when water appears, and whether previous repairs have been attempted.
