People who use the phrase 'as strong as concrete' are clearly not aware that the material is porous. The process of concreting itself is such that it leaves behind pores that water can permeate through. The quantity of water may be negligible at first, but when exposed to water for few years, the pores start becoming bigger and then you're going to have a problem.
It is advisable to use a sealer as soon as the concreting project is completed. In case you hadn't done it then, and your floor has already started leaking, better do it now than later. The sealers are acrylic, water-based solutions used to fix leaky floors. They are made basically from resin material. The other advantage is that it gives your concrete floor a really good finishing touch. It protects the concrete from dust, moisture, acid spills, and more or less everything!
Film Formers:
Like the name suggests, film former sealers create a film on the surface of the concrete, protecting it from everyday wear and tear, and stops water and other impurities from permeating the surface. It creates a luster on the surface and is used more extensively on colored concrete floors to enhance the color visibility. So, if your floor is to have that glossy look, film formers are the thing for you.
Again, a very self-explanatory name. Penetrates get into the pores that allow water in and fill and block them. Unlike film formers, they do not lend a lustrous, shining finish to the floor. These will give your floor a matte finish.
Another thing to think about is Acid Concrete Stains. These stains will enhance the aesthetic value of your floor and are a good substitute to carpeting. Acid staining can be done in any required pattern and is used especially on homes and offices.
How to Apply
  • Choose the type of sealer (film former/penetrate) which is most suitable to the sealing work. Clean the floor. Remove any signs of accumulated dirt with a high pressure washer to avoid sealing the dust as well. Wash the floor again with a combination of water and vinegar so that any lime that may have come to the surface will be removed.
  • Depending upon the sealer, you may need a brush or a sprayer that will help you to apply it onto the floor. Directions for the same will be given on the can. Allow the coating to dry. The drying time is sealer specific and may range from one day to seven days. You may also need to apply a second coat and wait again. Once the sealing is done, clean the floor yet again.
  • After the floor is sealed and ready, if you want, you can color it with the stain. You can apply the stain as a straight color or in a pattern or design. And your waterproof concrete floor is ready!
Make sure that the sealer is uniformly applied. If it does not get applied uniformly, then you run the risk of having to go through the entire process again. While this is a generic process, follow the manufacturer's instructions for some specific aberrations.
