Concrete cracks create direct pathways for water to enter basements, crawl spaces, and structural walls. In Lewes and surrounding neighborhoods, shifting soil, coastal moisture, and hydrostatic pressure make these issues worse over time.
Platinum Roofs uses professional-grade injection systems, including KEMKO-based solutions, to seal cracks internally and stop water intrusion at the source.
These systems expand within the crack, bond to the surrounding concrete, and create a long-term watertight seal.

Concrete crack injection is a targeted repair method that seals the full depth of the crack from the inside. Systems like KEMKO are injected under pressure, allowing the material to expand and bond within the crack to block water completely.
This process avoids unnecessary excavation while still addressing the root of the problem.
Crack is evaluated to confirm injection suitability
Injection ports are installed along the crack
KEMKO-based material is injected into the crack
Expansion creates a sealed, watertight barrier


Concrete crack injection requires precision and the right materials to be effective long-term. Platinum Roofs applies proven injection systems designed specifically for structural leak remediation, not temporary fixes.
Our team focuses on identifying the true source of water intrusion and applying the correct solution based on how the structure is performing.
Certified installation for injection systems
Experience with residential and commercial structures
Accurate diagnosis before repair begins
Concrete naturally develops cracks over time, but in coastal areas like Lewes, those cracks are more likely to allow water intrusion due to constant moisture exposure and soil pressure.
Once a crack forms, water can move through it and spread behind walls, into crawl spaces, or across foundation surfaces. Without proper remediation, this leads to repeated leaks and long-term damage.
Hydrostatic pressure forcing water through cracks
Soil movement and seasonal expansion
Moisture exposure from coastal conditions
Small cracks expanding over time

Concrete crack injection is a repair method that fills cracks internally using specialized materials such as KEMKO-based systems. These materials expand within the crack to seal leaks and stop water intrusion at the source.
Yes. Crack injection seals the full depth of the crack, while surface patching only covers the outside. Injection systems provide a longer-lasting solution for water intrusion.
Most structural cracks can be repaired using injection, but the crack must be evaluated first to confirm the right approach.
When properly applied, injection systems are designed to stop water intrusion long-term by sealing the crack internally.
High-quality injection repairs can last for many years, especially when the underlying cause of the crack is addressed.
