3-Year Workmanship Warranty on Every Pour

Most concrete problems trace back to what's under the slab, which is why this warranty is about base preparation, reinforcement and installation — the parts you can't see once it's poured — and not just the finish on top. The terms below are the same ones printed in the Terms & Conditions that come with your estimate.

What's Covered

For three years from completion, if any of the following is caused by our workmanship, we repair or replace the affected area at no cost to you:

• Sinking or settling slabs caused by improper base preparation.
• Uneven slabs resulting from installation error.
• Structural cracks caused by inadequate reinforcement, improper joint placement, or substandard installation practices.
• Incorrect slope or drainage grade that does not meet the agreed-upon specifications.
• Improper finishing including broom finish inconsistencies, stamped pattern misalignment, or exposed aggregate defects caused by workmanship.
• Any other defect directly attributable to ZBL Concrete & Design's craftsmanship or installation methods.

What Concrete Does Naturally (Not Covered)

Concrete is a natural product. These are normal behaviors of the material, not defects, and they're excluded:

• ✕ Hairline cracks — Small surface cracks are a natural result of the curing process and do not affect structural integrity. They may appear within days, weeks, or months after installation.
• ✕ Spalling — Surface flaking or peeling from freeze-thaw cycles, de-icing chemicals, or harsh weather.
• ✕ Chipping — Minor chips or surface damage from impact, heavy objects, normal wear and tear, or improper use of de-icing products.
• ✕ Color variations — Slight differences in color or shading across the surface from curing conditions, moisture levels, or material composition.
• ✕ Efflorescence — A white powdery residue that can appear as moisture evaporates through the concrete. Natural and temporary.

Other Exclusions

• ✕ Damage caused by third parties, acts of nature, or events beyond our control.
• ✕ Modifications or alterations made to the concrete after installation by anyone other than ZBL Concrete & Design.
• ✕ Normal wear and tear over time.
• ✕ Damage resulting from failure to follow the care and maintenance instructions provided.
• ✕ Subgrade or soil conditions that were not disclosed or were not reasonably discoverable at the time of installation.

Your Part: Keeping the Warranty Valid

• Let it cure — Minimum 7 days before foot traffic and 30 days before vehicle traffic, as directed at completion.
• No de-icing salts the first winter — Use sand for traction the first winter season; no salts or de-icing chemicals on new concrete.
• Seal it — Apply (or have us apply) a concrete sealer as recommended to protect against weather damage, then reseal every 2–3 years.
• Tell us early — Notify ZBL Concrete & Design of any concern within a reasonable time so it can be inspected before it gets worse.
