With V Works Mobile Mix Concrete, the customer only pays for the concrete that is used. When the job is completed, the concrete mixer is turned off. There is no waste and no paying for unused concrete! With drum trucks, the customer pays for any unused or extra concrete, increasing costs. V Works Mobile Mix Concrete trucks can deliver small loads or be used as a batch plant at the job site to produce up to 60 yards of concrete, per truck, per hour. This saves the customer time and money. V Works is a residential/commercial contracting mobile mix concrete and excavating company with 20 employees. Our jobs require 50% down at the beginning of service and the remaining balance will be billed and mailed to the customer. We offer promotions of a 10% discount to our Vets and Senior Citizens with proof of ID such as military card and driver's license. Even though you could possibly be a Senior Citizen and Vet you are only able to use a 10% discount and not a combination of both.

Foundation Repair questions, answered by experts

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Yes, you can live with a cracked foundation—in fact, most people do. Virtually all foundations crack from normal settlement, and while settling cracks benefit from sealing to prevent water and moisture intrusion, most aren’t an issue. If you have structural cracks in your foundation, it might be safe to live in your home for some time, but you should address them immediately to prevent structure collapse and major property damage.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
