3 Ways to Prevent Spalling Concrete for Ronkonkoma, NY Residents

Spalling Concrete, like leakages and cracks, begins with moisture. Spalling occurs when water penetrates the concrete surfaces of walls, walkways, or pavements, leading to swelling of the layer.

Are the concrete surfaces of your home’s walls or pavements chipping and flaking away like old skin layers being molted? This occurrence is known as Spalling Concrete. A spalled surface appears, from a distance, like a depression into the concrete surface.

As concrete absorbs water (or moisture), the concrete itself undergoes chemical reactions. These reactions result in physical changes to its appearance.

To prevent spalls, use a water sealant. An effective water sealant, like the Basecrete Intercept or BRK 50, will limit the movement of water into the pores in your concrete surfaces.

A second approach is to ensure proper finishing procedures. An early finishing of concrete may trap air within the concrete, which causes the outer layer to break when exposed to freezing temperatures. Premature finishing can also trigger excessive bleeding, which combines with the trapped air to weaken the concrete. Let the concrete set properly.

Spalls are prevented when water is adequately drained off the affected surfaces. The drier a Spalling Concrete, the less prone to spalls. Ensure proper sloping of the concrete surfaces – particularly the pavements, walkways, and driveways.

Essential Tips for Repairing Spalling Concrete for Holbrook, NY Residents

Repairs for spalled concrete is primarily determined by the location and type of the concrete, and the severity of the spall.

When concrete surface spalls, the rebar may have been exposed to humidity and moisture, or the concrete joints may have been hurriedly cured. With time, the concrete expands, creating cracks within itself.

  • If you’re unsure of the duration of the spalling, contact an engineer or a professional in related field for a thorough assessment of the structure.
  • Assess the depth of the damage. Surface flaking can be repaired by applying a cementitious overlay. This will prevent the absorption of water or moisture. For damages more than 1/3” thick, the rebars should be reinstalled.
  • The degree of corrosion of the rebars will suggest a replacement or a cleaning. If removable, the rust should be completely cleaned and coated with rust inhibitors.
  • For walkways, driveways, and pavements, you should overlay the spalling region with cementitious products. To reinforce its effect, combine the cementitious product with a waterproofing product like the Basecrete BRK 50.
  • Before patching or overlaying concrete surfaces, ensure the region is cleaned of debris and loose particles. This will prevent sealing of dirt into the cracks.
  • The effectiveness of the cementitious products will increase with increased dryness of the concrete surface. Ensure the surface is dry before pouring your cementitious mix.
