Your homes foundation is the base on which everything else is built, so it can be considered the most important part of your home. Whether your need to repair your foundation, install one, raise it or level it, you want to be sure that you hire the absolute best person for the job - which is not always the cheapest nor is it the most expensive! The key to a successful foundation is the experience that your contractor possesses and the references they can provide. Their relationships with others are important as well as one person cant take on a job this large by themselves. They need to have established relationships with people you can trust.
Whether you are installing a foundation that will accommodate a basement or crawl space or if your foundation will be a concrete slab, it is important to do whats best for your home as well as your geographical area. Soil implications may dictate the type of foundation that you will have to install. Basements are great for the Northern areas whereas crawl spaces are better for the middle portion of the country. If youre in the South, you probably will need to install a slab. Slabs are the least expensive option, but if you think you might want to have a basement for extra living area, you should consider that as well. For foundation installation you might need to pay for an architect, a landscaper (to adjust grade if needed) as well as people to deliver the supplies as well as install them. Continue Reading
Concrete often fails due to poor soils, voids, tree roots, moisture, etc. Settled concrete generally create a vertical displacement, which is a huge liability, especially if this is your sidewalk or driveway.
Mudjacking is also known as: slabjacking, concrete raising, and pressure grouting. Mudjacking is a cost-effective alternative to replacing concrete. Mudjacking (or concrete raising) can usually be done for less than half the cost of pouring new concrete. However, the savings may be even greater since concrete raising eliminates the costs of demolition, removal, and landscaping. Mudjacking is the process of pumping a water, dirt and cement mixture under a concrete slab in order to lift it. Once the mudjacking is complete, both the concrete slab, and the soil beneath it, will be much more structurally sound.
Polyurethane concrete raising achieves the same results as traditional mudjacking with a lightweight material that requires smaller and fewer injection holes. Also known as Foam Lifting, polyurethane concrete raising is the latest and greatest concrete repair method. Essentially, foam is injected into the soil, which will result in filling and expanding into all the voids, lifting and aligning the concrete, stabilizing the soil and concrete from moving again. This method is more expensive than mudjacking.
Piering is another type of concrete foundation raise repair. This method involves using jacks to raise the sunken part of the foundation. This is a delicate process as raising the foundation too quickly can cause further damage. Once the foundation has been brought back up to grade piers and footing are installed to support the foundation and keep it in place and is the most expensive means to raise your foundation.
If you have poor soil, you may need other remedies besides solely raising your concrete. Concrete raising may only be a temporary solution. Be sure to address this with your contractor.
Foundation drainage refers to any system designed to divert or direct water away from a foundation. Such drainage includes systems installed outside the edge of foundations as well as systems that are installed under foundations.
In many areas the ability of soils to support a foundation is affected by the amount of water in the soils. Too much water can cause soils to be muddy, and a foundation can sink. Too much water, and expansive soils will lift a house up. Good foundation drainage helps to keep excess water away from a foundation and to prevent problems.
The cost of foundation drainage normally starts at around $1,500 and goes up from there depending on the amount of yard contouring or French drains that need to be installed. More elaborate drainage systems cost more.
