The 90-minute rule refers to the industry standard that concrete must be placed and consolidated within 90 minutes of the water first being added to the mix at the batch plant. This time limit is critical because the concrete begins its initial set after this period, and exceeding it can compromise the material's strength and integrity. For homeowners in Walnut Creek and Contra Costa County, adhering to this rule is essential for a durable foundation. At Golden Bay Foundation Builders, we strictly monitor delivery and placement times to ensure compliance. For a deeper understanding of the entire process, we recommend reading our internal article titled How to Build a House Foundation: The Definitive Step-by-Step Guide, which covers all critical timing and placement standards.

Yes, damaged concrete can often be repaired, but the method depends on the type and severity of the damage. For minor cracks or surface spalling, professional resurfacing or epoxy injections are effective solutions. However, for structural issues like deep settling, severe frost heave, or extensive crumbling, a full replacement may be more cost-effective and safer. At Golden Bay Foundation Builders, we always assess the underlying cause first, as repairing symptoms without addressing the root problem leads to recurring failure. For homeowners in Walnut Creek and Contra Costa County, understanding the cause is critical.
