We have 2 divisions within the company, Basement Authorities which specializes in basement waterproofing, structural foundation repair, dehumidification and helical piering and NuRock Creations which specializes in Decorative concrete, outdoor living, decorative hand carved structural retaining walls, and flat work.

"It has two years of trying to work with Robert Nelson of RWN over simple installation of stairs. In emails he said he would remove the and redo the steps but he never returned. Steps were supposed to replicate in color and texture of two granite steps in place. As you can see in the photo they aren't. Frustrated I asked Small Claims court to help. Thankfully they did and in my favor."

Concrete Leveling questions, answered by experts

Yes, you should seal your exposed aggregate concrete to keep it protected from the elements and reduce the risk of cracking and concrete spalling. You’ll need to invest in the cost of resealing your concrete about every three years to keep it in good condition. Unsealed exposed aggregate concrete is susceptible to water damage, stains, chips, cracks, and abrasion. Sealers are available in various finishes and levels of gloss. Outdoor exposed aggregate concrete should be sealed with a non-yellowing, UV-resistant sealer to preserve the look of the finish.

You should put gravel that is 3/4 to 1 inch under a concrete slab. However, depending on the project, local building codes may dictate the proper gravel size and shape. Some concrete slabs that do not hold significant weight may have a subbase of sand. Also, keep in mind that the subbase you choose will affect the cost of your concrete patio, walkway, or driveway.

In most cases, yes, sealing concrete will stop spalling. However, it’s not a perfect solution—it may only delay spalling. Call your local concrete repair contractor for quotes on the best sealing options to prevent spalling.

Like all concrete, pervious concrete is susceptible to cracking due to expansion and contraction from freezing and thawing or heavy weight. Pervious concrete, however, is less likely to crack due to moisture intrusion than traditional concrete since pervious concrete is designed to drain and hold water in the material’s voids.

Concrete houses will last for between 75 and 150 years, depending on the environmental factors in your area. Unlike lumber in stick-built houses, concrete doesn’t rot, and it’s more resistant to wildfires and earthquake damage, so you’ll almost always get a longer lifespan from a concrete house than you would a traditionally framed one.
