Floor Slab Crack Stitching
Crack stitching. Stitch interior floor when floor heaving is caused by foundation settlement around the perimeter foundation walls. This downward movement of the foundation walls will break and compromise the stability of residential homes or commercial building structures. Vertical breaks on the viewable exterior foundation walls can be easily identified; more numerous these breaks mean the movement continues, accelerating downward. (Also known as settling cracks).
Because the outward pressures of interior floating floor slabs, specifically stem wall construction, will follow the foundation vertical wall down, causing random sporadic floor heave cracks, the interior floating floor slab construction joint next to the interior foundation wall will slip.
It will look like the interior floor is moving upwards at heave as the exterior foundation continues moving down. (foundation settlement left and or right of heave crack on exterior) As the foundation wall vertical cracks become more numerous, from excessive moisture holding and penetrating to the subgrade supporting structure, where roof rainwater concentrates and or dirt grading is negative to the foundation wall, interior water lines are in imminent danger of breaking. If interior water lines break, expansive soils (if present), may exacerbate the heaving cracks on interior floor slab.
Foundation inspection by highly skilled evidence-based foundation expert James Belville can identify the warning signs. Rain gutters and dirt grading is recommended if evidence suggests heave cracking. Crack stitching methods using steel rebar or carbon fiber for repairs.
Residential and Commercial (Key Way) Joint Heave Crack Stitching
Key ways are a tongue and groove joint. Tongue and groove provide a mechanical interaction between two adjacent concrete slabs. Key ways are often put in longitudinal construction joints to transfer load between two paving lanes. Load transfers across the joint, reducing-edge stress. Stress reduction helps prevent cracking that might result from heavy loads. Some construction joint details include tie bars with a key way. The key way provides interlock, while the bars hold the joint tight. A key way also helps keep the two slabs at the same level, preventing any faulting that might develop along the construction joint due to differential subgrade settlement. This type of key way is used in residential home floors as a control joint with tongue and groove properties to help adjacent slabs from heaving elevation changes. By installing this type of tongue and groove key way on interior floating floor slabs (introduced while pouring), the interior floor is then compromised and is likely to heave at the location of the key way joint.
Heave Crack Identification
(1). Keyway heave joint cracks can easily be identified. The cracks in the tile or floor, for example, will be in a straight line. Tile cracking and/or grout joints.
(2). Random sporadic cracks can easily be identified by the definition of sporadic. (Occurring at irregular intervals or only in a few places; scattered or isolated).
Heave Crack Grinding, Crack Stitching, and Floor Leveling Methods
These cracks can be ground and leveled for tile, carpet, or wood flooring without expensive analysis and push pier installation. Epoxy crack stitching using #4 steel rebar is recommended.
