Damaged Driveway - Repair Or Replace? Three Things You Must Consider

Your driveway is the entrance to your home and one of the first things to get noticed by visitors. If the driveway is busted or overwhelmed with unappealing cracks it can leave an unpleasant impression. More often than not, this is a problem that goes unaddressed.

If you have a driveway that is cracked or busted and are ready to address the problem you have two basic choices, replace or repair. Three things you must consider when making the decision to replace or repair.

1. Most driveways are a minimum of four inches thick. Natural stresses caused this four inch thick slab of concrete to literally tear itself apart. These stresses include expansion and contraction due to heat and cold, the weight of vehicle traffic, and movement of the substrate. Any crack repair material placed within these fractures will undoubtedly suffer a similar fate as the original slab of concrete, failure.

2. Driveway replacement can be expensive but if performed correctly can provide you with fifty plus years of solid use. If you decide to replace a concrete driveway make sure the contractor uses a four thousand psi mix of concrete poured at a minimum of four inches; furthermore, steel reinforcement should be added for increased tensile strength to compliment the already high compressive strength of concrete.

3. Over time, a driveway's surface can become weathered and lose its finish. There are a variety of overlays available. Although relatively expensive, when compared to the cost of replacement, these overlays can be a viable option. I don't suggest overlaying cracked or busted concrete; however, if the desired effect is simply a nicer finish then overlay can do the trick.

Concrete repair can be a risky endeavor. Far too often, I see a repair gone wrong, a costly mistake that never should have been attempted in the first place. Every day, home owners waste money on costly repairs that fail. That being said, cracks can be filled to prevent moisture penetration and good concrete can be overlaid for aesthetic appeal.

Many times, due to budget restraints, the best solution is to simply cut out and replace only the most severely damaged sections. This way, you spend less money and the repair is solid.

Why You Should Consider Staining Your Concrete Floor

Acid staining can make a common concrete floor into look like expensive natural stone flooring. Not only is it a fraction of the price, but for people allergic to carpeting materials it's a godsend. Another great application is in houses with radiant floor heating. Radiant heating is at its most efficient when insulating floor coverings like tile or carpet are minimized.

The process of staining a concrete floor, while not overly complex, can be tough to get the results you want from. Most folks are probably better off hiring a professional contractor. It's a risky project for the do-it-yourselfer.

If you're not familiar with it, concrete stain isn't a paint or finish coat. It involves a chemical reaction on cement materials. Typically a water-based solution of hydrochloric acid and inorganic salts, the stain reacts with minerals and lime in the concrete aggregate, and the result of the reaction is coloring. It works on new or old concrete, and is fairly durable if you maintain it with sealer or wax, since it won't stain or chip. It can also be applied to both interiors and exterior floors. Walkways, bathrooms, entrances, driveways, living rooms and patios are all fair game.

When it's finished, stained concrete looks a little like marble, but more dappled and less uniform. The concrete will mostly be earthy brown tones, with hints of red and green. It's possible to make your own tint stain by mixing colors, or applying at dissimilar rates. When you stain a concrete floor, though, don't expect the stain to be uniform or have an even tone. Plan your room décor and color scheme accordingly, because you'll get dissimilar reactions from different areas of the concrete, and even a seasoned pro will be hard pressed to predict what the final result will be.

Surface prep for acid staining concrete depends on what condition your slab is in. Newly poured concrete only needs is be allowed time for curing- three weeks after pouring- then some rinsing and scrubbing. Older concrete is a different story. Thorough cleaning is required because any dirt, grease, paint, sealer or even curing agent will keep the stain from penetrating and reacting as it should. Do a little test area to make sure it's ready.

Newer poured concrete will require less stain than older floors, but in general, a gallon of water added to one gallon of stain will cover around 400 square feet. Apply the stain with a non-metallic brush or broom, working in the cooler morning or evening hours, rather than in the heat of the day. Be careful to protect yourself from spillage, drips and fumes from the acid stain, and follow the manufacturer's precautions.

After application, you need to cleanup by sweeping away any leftover stain and residue with a broom. When the floor is thoroughly dry, it is a good idea to apply a sealer agent and then wax it.

If you are in the market for natural stone flooring, a new look for your basement or patio, or just looking for new remodeling ideas, stained concrete is certainly something you should look into.
