How much does it cost to patch a concrete driveway?
Patching a concrete driveway is somewhat similar to sealing an asphalt driveway. It is something that is quite possible to do on a DIY basis, but it is a bit more demanding than simply spreading an asphalt sealant.
For the purpose of this discussion we will take a look at the costs and requirements for patching a concrete driveway on a DIY basis. The measurements of the drive are 15'x50' (or 750 square feet) which is a somewhat standard set of dimensions for a residential driveway. The average costs for such work are around $3 to $5 per square foot, which is around 50% of the average price for hiring a contractor to tackle the work. This means that it will cost less than $300 to do the work independently.
According to DoItYourself.com it requires only a few basic tools and materials to perform such a repair. Including:
- Tools - a hammer and chisel are necessary for undercutting large cracks or holes prior to filling, a wire brush, a shop broom, a tire pump or garden hose for eliminating debris, concrete adhesive (usually the acrylic resin types work best), a paint brush, pre-mixed concrete patching (for small jobs) or a combination of Portland cement along with sand and gravel, and plastic sheeting; and
- Concrete patch - as mentioned above it is necessary to understand the size of the repairs and the amount of patching that will be required. When holes or cracks are substantial the homeowner is going to have to make a standard mixture of one part Portland cement, two parts sand and three parts gravel adequate to the needs of the job. This is not a costly repair and the RSMeans cost calculation software places it at roughly $3.20 per square foot.
Enhancement and improvement costs
- Resurfacing - in addition to making DIY repairs on the concrete driveway it is also a good idea to consider doing a resurfacing too. This will usually require power washing, crack repair with reinforced fabric, grinding of the polymer sealants, filling of holes and then the application of a surface polymer. This is something usually done by licensed contractors with experience in handling the somewhat difficult chemicals. According to ConcreteIdeas.com a simple thin resurfacing will cost only $2.25 per square foot, and if color or patterns are imprinted in the surface it will only increase it $4 to $8 instead. This tends to be a practical solution for homeowners looking to increase curb appeal while simultaneously effecting concrete repair.
- Upkeep - one of the most costly mistakes made by homeowners who have just completed a concrete patching project, or even an entire resurfacing, is to wait only two days before using the drive. All concrete must cure for at least five days before it can be safely used, and during this time it should be kept undercover and continually dampened to allow the bond with the original concrete to become firm and permanent.
