Cracks that are the result of drying shrinkage, thermal fluctuation or other minor causes usually result in minimal damage. But, if they widen over time they can cause water seepage and compromise structural integrity. Foundation and slab cracks aren’t only undesirable to look at, but they reduce the value of the home or building.
After identifying the problem, we begin surface preparation. The most critical aspect of a concrete repair and restoration is preparing the substrate properly. The final overlay is meant to coincide with existing concrete, but it must have a solid base to bond to. That’s why Valroc Development LTD. only uses the best machinery for this thorough job. The basic steps include:
- Cleaning the concrete and stripping all coatings, sealers, and paints
- Removing failing concrete, such as spalling or delamination
- Filling cracks to ensure the overlay doesn’t mirror them
- Profiling the concrete surface to improve the overlay’s grip
During the repairing process, the cracks and flaws are fixed but remain noticeable and unattractive. That’s why we have a variety of overlay options to have the surface updated, stylish, and new. The types of overlays we provide are as follows:
Microtoppings or skim coats: Can either be textured or smooth. These are easy to incorporate color and marble-like appearances, as well as accent with stains and dyes. They are polymer-based, which makes them much more flexible than other systems. Can also be applied to wall surfaces.
Spray-down systems: Ideal for stencil use. They can either be pre-colored or have the color mixed in, as well as combined with stains, dyes, or tints. The finish is textured and durable, making it a very common application for pool decks, driveways, and sidewalks.
Stampable overlays: Can be used to create very realistic textures that resemble brick, stone, slate and a variety of other options. There are many options for color, including colored liquid, powdered releases, dyes, sealers, stains, and broadcast pigments. Stamped overlays are applied thick enough to cover imperfections in the concrete substrate.
Self-leveling overlays: Perfect for saw cut or engraved designs. Integral pigments and stains are used to achieve color. Generally used for sound yet worn concrete surfaces and correcting uneven floors.
Underlayments: Provides a level base to restore structurally sound yet worn concrete. Acts as a smooth preparation for floor coverings.
