The National Association of Realtors® reports that foundation cracks form over 85% of new home problems. Based on this figure, it is obvious you must be on the lookout to protect your precious investment.
Capitalizing on Foundation Repair Expertise
It becomes easier if you notice foundation problems early in order to call a foundation crack repair contractor to avert further damage. Foundation cracks are primarily caused by excess moisture, poor concrete laying, tree roots in the proximity, house settling and soil shrinkage, among other issues.
Professional Foundation Cracks Repairs
An established foundation contractor has prerequisite tools and skills to identify problems and promptly implement the ideal solutions. Some permanent techniques used in foundation crack repair include:
The application of epoxy and other sealants in foundation repair has always been shrouded in controversy. Professional contractors’ bodies such as Concrete Foundations Association (CFA) argue homeowners risk covering underlying problems when they use epoxy to fill cracks.
As such, only a foundation contractor should apply epoxy injection repair because they will have corrected the cause of the crack. The process also involves cleaning and pressure epoxy injection, which only a professional can handle.
This is another foundation crack repair, but again are always at logger heads regarding whether it is better than epoxy or not. While epoxy restores your foundation’s structural integrity, polyurethane foam fills the crack with an expanding resin to accommodate soil movements as seasons change.
This is part of the more advanced foundation crack repairs and requires high expertise which only a certified foundation contractor can guarantee. It involves drilling both sides of a crack and grouting in using metal units that spin this crack. Such anchoring requires extensive excavation and specialized equipment, but the end result is worth the effort as tensile strength is re-established.
Drilling and Key-Plugging
If cracks run in a straight line and are accessible at one end, drilling is done down the length of the crack and plugging is done using a grout key. This key is instrumental in avoiding transverse movement of concrete blocks adjacent to the crack, which can exacerbate the foundation crack.
This advanced foundation crack repair is used for very wide cracks and involves cleaning of the crack, fitting of grout nipples at intervals astride the cracks and sealing of the crack with grout, flushing the crack and sealant and then intense testing to confirm strength of the built-up seats.
Well, you have to agree these techniques are skill-intensive and if you really value your investment, then forget DIY and hire a foundation expert; they are worth every dollar.
