The microorganisms in the powder eat hydrocarbons in the oil and convert them into water and carbon dioxide. Let’s be honest, pouring laundry detergent on your driveway and washing it down the sidewalk is not the most environmentally friendly thing to do.ĮXIMO uses a natural process called bioremediation to breakdown the oil. It has been shown that laundry detergent is responsible for 50% to 75% of the phosphorus in lakes and rivers - leading to vegetation overgrowth and fish mortality. Or, you can find it in a 3 lb tub that will take care of large or continuous oil spots.ĮXIMO is safe for pets and the environment, unlike laundry detergent, dish soap or WD-40. It is available in a small 12 oz package that will give you enough cleaner to remove an average sized oil spot from under one vehicle. Our favorite brand of concrete cleaner is called EXIMO and can be found on Amazon ( check price). We prefer to use a natural waterless concrete cleaner because it is easy to use and better for the environment. Related: What’s the difference between 5w30 and 10w30? Step 1: Use a Natural Waterless Cleaner What you should do instead is use a product that is designed to naturally break down the oil, without all of the elbow grease or wasted water. That’s because none of those products were specifically designed to remove oil from concrete or asphalt. Unfortunately, none of these methods will effectively get rid of oil stains. If you’ve searched for ways to remove oil stains online, you’ve probably found a number of crazy ideas such as using: Finally a waterproof coating is applied.Do you want to remove oil stains from your concrete or asphalt driveway?Īre you tired of your Homeowners Association (HOA) telling you to clean up those unsightly stains? The surface area of the concrete structure can then be prepared by abrasive or water blasting and a fairing coat applied to bring the structure back to its original depth. Depending on the scope of works, cathodic protection (corrosion protection system) might be used before the concrete repair mortar of choice is used to fill out the repair area. The exposed steel would then be cleaned and prepared back to bright steel before treatment to protect it in the future. This, in turn, causes a high rate of failure to the surrounding area.Ī concrete repairs specialist will remove the area around the spalled steel, removing concrete back to sound substrate. As the concrete around the steel is broken down by carbonation the corrosive effects of the air and water rust the steel causing it to expand, spall and crack. As carbon dioxide travels deeper into the concrete it reaches the steel reinforcement embedded in the structure. ![]() Depending on the permeability, concrete carbonation may advance at a rate of 1 – 5mm per year. Alkalinity then reduces in the concrete and it starts to breakdown. This forms calcium carbonate that initially hardens the concrete, raising the compressive strength. Carbon dioxide slowly penetrates the surface of the concrete, reacting to moisture and calcium hydroxide that is found in concrete. In untreated concrete, the process of carbonation is nearly impossible to avoid once exposed to the elements. ![]() Why do you need a concrete repairs specialist?
