⚠️ Surface Repairs Over Structural Problems Always Fail
The most common concrete repair mistake is applying a surface treatment or partial-depth patch over damage that extends through the slab or is caused by base failure. The patch bonds initially but fails quickly as movement continues beneath it. 633 Asphalt always probes and assesses the underlying slab and base condition before specifying any repair — to ensure the fix we recommend will actually last.
Concrete Repair Materials — Matched to the Job
Repair material selection significantly affects longevity, return-to-service time, and how well the repair integrates with the surrounding concrete. We select materials to match the repair depth, exposure conditions, and traffic timing requirements of each project.
Fast-Set Concrete
Rapid-Set Repair Mortar
Achieves 2,500–3,000 PSI in as little as 1–4 hours. Used when return to traffic is critical — parking lots, driveways, commercial access routes. Requires careful temperature management during Oklahoma summers.
Best for: Time-critical repairs, parking lots
Standard Mix
Portland Cement Concrete
Standard 4,000 PSI concrete mix for full-depth panel replacements and large partial-depth areas where rapid open time is not needed. Air-entrained for Oklahoma freeze-thaw durability. Most economical per cubic yard for large-volume repairs.
Best for: Full-depth panels, large areas
Polymer Modified
Latex-Modified Mortar
Polymer-modified repair mortars have enhanced bond strength to existing concrete, reduced permeability, and improved freeze-thaw resistance. Well-suited for thin partial-depth repairs and horizontal surfaces exposed to Oklahoma de-icers.
Best for: Thin patches, high-exposure surfaces
Injection Resin
Epoxy / Polyurethane Injection
Low-viscosity epoxy for structural crack bonding in dormant cracks. Polyurethane foam for active cracks and water infiltration. Both are injected under low pressure through surface-mounted ports spaced at crack width intervals.
Best for: Dormant structural cracks
Silicone
Self-Leveling Silicone Sealant
Flexible, self-leveling silicone for horizontal joints requiring maximum movement accommodation — typically wide expansion joints around structures. Silicone does not degrade with UV exposure and outlasts hot-pour rubber in wide-movement joints.
Best for: Wide expansion joints, structural interfaces
Signs Your Oklahoma Concrete Needs Repair
If you observe any of the following, schedule a free assessment before the next Oklahoma winter — freeze-thaw cycling will worsen every item on this list between now and spring.
🪨Concrete surface flaking, pitting, or breaking away
🔲Visible cracks wider than a credit card thickness
📐Height difference between adjacent slab panels
💧Water pooling on the concrete surface after rain
🔩Rust stains on concrete surface from rebar below
⚙️Joint sealant missing, cracked, or pulled away from edges
⬇️Settled or sunken slab sections creating a trip hazard
🕸️Map cracking or fine surface crazing across large areas
