A beautiful stone paver patio is a cornerstone of many home renovations, offering a durable and elegant outdoor living space. Homeowners are increasingly choosing interlocking concrete pavers for their aesthetic versatility and structural strength. However, the dream can quickly turn into a frustrating problem when those same pavers begin to sink, creating an uneven and hazardous surface.
This common issue is not a flaw in the pavers themselves, but in the foundation beneath them. For residents in San Carlos and the surrounding region, Exterior Pavers Designs Inc. provides a specialized approach to hardscape construction that addresses the root causes of sinking to ensure a lasting patio.
Why Patio Pavers Start to Sink Over Time
When you see a sunken paver, it is natural to assume the stone itself has failed. However, the issue almost always lies with the base. According to the ASTM C936 standard set by the Concrete Masonry & Hardscapes Association (formerly ICPI), concrete pavers are manufactured to withstand a minimum average compressive strength of 8,000 psi (approximately 55 MPa), with typical industry ranges between 40 MPa and 60 MPa. This means individual pavers can withstand immense vehicular and pedestrian weight without cracking.
