To ensure your concrete patio, driveway or sidewalk stays looking like new longer, and to improve the longevity of the surface, steps should be taken to ensure your concrete is treated appropriately. Freshly poured concrete is very susceptible to damage and should be treated gently for at least the first 30 days after pouring.
New concrete is highly saturated with water, and the water in it can freeze when the temperature drops. For this reason alone, concrete should not be poured in the late-Fall in climates such as that of Northern Virginia. While concrete that has been allowed to properly dry is perfectly suitable for winter conditions, proper materials and installation techniques must be used.
For the best results from concrete, request your contractor uses only concrete with a minimum compressive strength of 4,000 pounds per square inch. This not only provides a stronger surface, it also helps protect the material from salt damage in the winter. Here’s why.
Concrete is a porous material, which absorbs liquids rather quickly. When salt, commonly referred to as rock salt, is used to melt snow and ice on concrete, the salt melts and is absorbed by the concrete as well. When the water/salt mixture enters the pores of the concrete it becomes a mush-like substance. As the temperature drops, the mixture freezes, expands and can break the concrete apart creating cracks and spalling. When concrete with a minimum compressive strength of 4,000 pounds is used, the material is compressed tighter, allowing it to repel more water than is absorbed. This reduces the likelihood of salt damage.
To avoid salt damage to your concrete consider using an alternative to salt such as sand. Sand obviously will not melt ice or snow, but instead provides traction for driving and walking while not harming your concrete or surrounding landscape.
