One way to make normal concrete waterproof is to add a waterproofing admixture to the concrete mix. This admixture can help to reduce the porosity of the concrete, making it more resistant to water penetration. Another method is to apply a waterproofing sealer or coating to the surface of the cured concrete. This can help to create a barrier that prevents water from seeping into the concrete. Additionally, using a lower water-to-cement ratio in the concrete mix can also help to improve its waterproofing properties. **
