Is concrete waterproof?

Concrete is incredibly durable and versatile, but it’s not bulletproof. Concrete can crack and stain over time if it is not sealed properly, especially when it is exposed to heavy amounts of water. Thankfully, there are ways to prevent these issues and protect the structural integrity of concrete. Let’s take a closer look at concrete waterproofing and the importance of specialty coatings. 

Concrete is not naturally waterproof

Concrete consists of water, aggregate particles, and cement. It can be poured into any shape imaginable and used for a variety of surfaces. As the concrete dries, it becomes porous, leaving it susceptible to water infiltration in the future. 

Concrete may appear waterproof during a heavy rainstorm because water pools on the surface. However, that doesn’t mean that there is no water below the surface. The concrete gradually absorbs water like a sponge, which could cause damage along the way.

Water can damage unprotected concrete structures 

Despite it being essential, water can be quite powerful. Though concrete is solid and tough, hit can still be damaged by water. As it soaks into the concrete, it erodes material inside the structure. This weakens the concrete and makes it more susceptible to water damage.

When left unprotected, concrete buildings are particularly susceptible to water damage. The water infiltrates the building, causing mold, mildew, surface stains, and much more. 

How to make concrete waterproof

The good news is that there are products available to make concrete waterproof. In some cases, special additives are mixed with concrete to make the final product less porous. In other cases, specialty coatings are applied on top of the concrete to seal it from water. 

The method for concrete waterproofing depends on where the concrete is located. Sidewalks and building exteriors receive different coatings than foundations or underground structures. If the concrete is exposed to persistent UV rays, the specialty coatings can also shield against sun damage.
