Reinforce Under-Supported Floor Systems
Support jacks are used to restore and reinforce crawlspace load paths where beams or joists are under-supported. Correct installation improves floor performance and reduces progressive structural deflection.
What Support Jacks Address
- Localized floor sag: Low points caused by inadequate or degraded support.
- Over-spanned framing: Structural members performing beyond intended load conditions.
- Progressive deflection: Movement that continues during seasonal moisture cycling.
Installation Principles
- Load path evaluation: Confirm framing stress points and support requirements.
- Base preparation: Provide stable footing/transfer surface for jack loads.
- Controlled adjustment: Gradual correction to reduce finish stress upstairs.
- Long-term stabilization: Lock support system for ongoing structural performance.
Pair Structural Work With Moisture Control
Structural reinforcement performs best when crawlspace moisture is controlled. We often combine support-jack projects with encapsulation and dehumidification.
Related Risk Context
- Moisture and wood behavior: Cyclic swelling/shrinkage can worsen framing movement.
- Settlement coupling: Floor sag can coexist with broader foundation settlement patterns.
If needed, we coordinate with foundation inspection and foundation stabilization recommendations.
