A concrete slab on grade is defined as a slab, supported by ground, whose main purpose is to support the loads by bearing on the ground. Residential slab on grade foundation systems generally consists of a concrete slab supported on the exterior by a perimeter concrete footing and in the interior by isolated pad footing or continuous interior footings.
Common indications of damaged slab on grade foundations are wavy slab surface, cracked drywall or stucco, and movement of the framing. Determining the causes of foundation damage is critical for determining the integrity of the structure.
Our licensed engineers can perform the necessary structural inspection for when the slab on grade damage is suspected. Our reports can help with an escrow to close, provide guidance for foundation contractors, or provide peace of mind for our client.
Raised foundations consist of exterior concrete foundation walls or wood framed stem wall/cripple walls and interior pad footings. The exterior foundation typically supports the gravity and lateral forces of the structure and the interior pad footings typically support only gravity loads.
Common indications of raised foundation damage are wavy raised floor surface, cracked drywall or stucco, and movement of the framing.
Our licensed engineers are able to assess the foundation system from the crawlspace. We will make qualitative assessments of the existing foundation system and provide our engineering opinion regarding the structural integrity of the residence.
