What Is Allowable Soil Bearing Pressure?

Allowable soil bearing pressure is the safe load soil can support under a footing. Here's how it's determined and why foundation design depends on it.

What Are Compaction Recommendations?

Compaction recommendations specify how fill and subgrade must be densified for stable support. Here's what they mean and why testing confirms them.
