Concrete Garage Floor Slab – Tips To Get The Best

Concrete Garage Floor Slab

Are you thinking of repairing the concrete floor slab of your garage? Are the cracks and holes that keep appearing on your garage floor a constant headache to you? If so, you should consider opting for a brand new concrete garage floor slab instead of repeatedly repairing your old one. With good ground preparation, right concrete mix and high quality steel reinforcing mesh you can get a garage floor which would last for several decades.

There are certain important factors to be considered to ensure that the garage floor you are planning to construct will be of top-notch quality. Go through these tips that we have compiled, with useful insights from, if you are thinking of getting a new one for your garage.

Due diligence
It is always advisable to get the quotes from more than one contractor if you are planning to outsource the work. But, don’t always choose the lowest bidder. Instead, do some research and understand enough about this work to be able to ask the contractors the right questions. Choose the one who can answer your questions convincingly.

Garage floor level
Many contractors still stick to the old building codes that used to stipulate that you build the garage floor four inches below the ground floor level of your house. This was meant to prevent any spillage of gasoline or carbon monoxide in the garage from entering the house. But, now this building code is no longer applicable making it possible to have the entire house (garage included) built at the same level. A four inch step would cost more than a level slab. If your contractor insists on a different level for your garage, ask him to show the evidence that it is a legal necessity.

Prepare the ground well
Many a times, it is not the weight of the things kept or parked on top of the slab that causes it to crack. The soil that moves underneath the slab is the culprit in such cases. Make sure that the topsoil was removed to ensure good ground preparation. If the soil had not been previously dug-up, then add at least four inches of gravel or stone. If the soil was disturbed, then ensure that it had been compacted before the layer of gravel too gets compacted.

Get the right concrete mix
The concrete slab should be at least four-inches thick – or even thicker if heavier stuff are going to rest on it. The standards for the concrete mix is expressed in terms of ‘compressive strength’ which is essentially the amount of water in the mix. Adding more water makes it easier to pour the mix, but makes for weaker slabs. Adding plasticizers to the mix is the solution to retain the compressive strength of the mix while making it easier to pour.

Good reinforcement
Steel reinforcing mesh is used to add tensile strength to the slab. Make sure it rests in the middle of the slab and not sink to the bottom when the concrete is poured.

With these tips in mind, go and get a great concrete floor slab for your garage.
