The Importance of Sealing Concrete

Concrete is the preferred material for driveways, sidewalks, pool decks, stoops, parking lots, warehouse floors, and factory floors due to its durability and long lifespan. However, without proper sealing, concrete is more susceptible to damage.

Despite its strength, concrete is a porous material that readily absorbs water. Water can erode the soil beneath concrete slabs and cause voids to form, compromising the stability of the structure. Additionally, water that remains on the surface can freeze and damage the concrete during colder temperatures. Beyond water, concrete surfaces can suffer from discoloration and damage caused by oil, fertilizer, salt, and chemicals.

Cracked and damaged concrete poses significant liabilities. Uneven surfaces from cracks become tripping hazards, allowing water to penetrate more easily, further eroding the soil and causing the slabs to collapse. This not only increases the risk of accidents but also leads to costly repairs.

Green Line Services provides top-notch concrete crack sealing services for all types of properties. Using polyurethane foam, we efficiently and effectively fill cracks in the concrete. If the concrete has already sloped or sunk, we can inject polyfoam into the soil below to level the slabs and reinforce the ground.

Benefits of Polyurethane Foam

  • Incredibly Durable: Polyurethane foam is long-lasting and can withstand heavy use.
  • Lightweight: The material is easy to handle and install.
  • Waterproof: It prevents water from seeping into the concrete and soil below.

Concrete Sealing FAQ

While concrete can still function without a sealant, sealing it is highly recommended. Concrete sealers extend the lifespan of concrete surfaces by protecting them from the elements. Acting as a protective barrier, sealers prevent the concrete from easily absorbing liquids and other harmful substances.

Green Line Services uses polyurethane foam to fill cracks and seal gaps in concrete. Polyurethane foam is a revolutionary material known for its durability, waterproof properties, and ease of installation.

Applying too much sealer on concrete can trap moisture underneath, which over time will cause the sealer to lose adhesion and become ineffective. Proper application is key to ensuring the longevity and effectiveness of the sealer.

It is recommended to seal concrete, especially outdoor surfaces. Outdoor concrete is exposed to the elements over the long term, making it more susceptible to deterioration and damage. Sealing these surfaces helps protect against weathering and extends their lifespan.

While the curing time may vary depending on the type of sealant used, it is generally recommended to stay off freshly sealed concrete for at least 24 hours to allow the sealer to cure and dry completely. In contrast, when polyurethane foam injections are used, concrete slabs are typically ready for traffic just 15 minutes after installation

Sealing concrete driveways, parking lots, pool decks, and other concrete surfaces is crucial because it protects the material from water, oil, salt, and other harmful substances. Without proper sealing, concrete is more susceptible to damage and cracks, accelerating the deterioration process.

It is best to seal concrete in the afternoon. The heat from the afternoon sun helps to dry out any moisture on the concrete, allowing the sealant to adhere better to the surface. This timing also prevents solvent bubbles, discoloration, and early evaporation, ensuring a smooth and effective seal.
