Concrete Sealing and Sandblasting
Concrete Sealing and Sandblasting in Edmonton is a regular maintenance item for your household routine typically performed in the spring and summer months. However, Concrete is an absorbent material. All concrete has microscopic holes that act like a sponge absorbing and holding water. Typically, most exterior concrete has air entrainment for the Canadian freeze-thaw cycles. Consequently, without the protection of a concrete sealer, water can freeze inside the cavities and cause your concrete to pop, spall, pit, or even crack.
Concrete sealing is essential and The Concrete Doctors know how to help prevent that from happening by properly concrete sealing yearly with either water or solvent-based sealer. We recommend performing preventative measures such as filling the cracks in your concrete and preventing water penetration. The concrete’s surface will dramatically increase your concrete driveways and walkways’ lifespan.
CLEANING AND POWER WASHING YOUR CONCRETE
Using the wrong psi pressure when power washing your concrete can leave abrasion and line marks. Our services include pressure washing the concrete with hand-held power washers and walk-behind surface cleaners. We offer biodegradable cleaners to lift and remove contaminants or a weak acid-based cleaner.
CONCRETE SEALING EDMONTON
The Concrete Doctors offers two varieties of sealing.
The first is a deep-penetrating water-based concrete sealant, which is absorbed into the slab to protect the concrete and preserve its longevity. This concrete sealer provides a waterproof barrier. The typical application for this product is on broom finish sidewalks, patios, steps, and driveways. Due to the Canadian winter’s freeze-thaw cycles, it is suggested that the concrete is cleaned and sealed every 1 -2 years after this sealant is applied.
The second sealer is a product, which is a proprietary blend of chemicals manufactured with silane for its protective prosperities. This product acts as a densifier to the substrate, which chemically alters the concrete’s micro cracks and microscopic voids. This protects the slab to the point where it cannot absorb water and helps prevent spalling, cracking and forming a hydrophobic barrier. This is a one and done solution and would need to be reapplied in the future depending on traffic levels and chemicals exposure.
FILLING YOUR CONCRETE
Cracks in concrete are expected; most companies will provide control joints or saw cuts to prevent unsightly cracking across a large spanning area when the concrete is first poured. The critical goal is to lessen the impact of the freeze/thaw process. Proper maintenance of patching or filling combined with sealing is a crucial step to maintain your concrete’s integrity.

Sandblasting and dustless concrete blasting is one of the many methods used to texture the surface or remove old Concrete to prepare a base. The amount of sandblasting needed will vary from light cleaning to a deep penetration that exposes the rock aggregates. Concrete sandblasting is sometimes messy and dirty; however, the operation is not particularly complicated.
Most jobs will need 150-160psi, and we have the ability to deliver about 300 psi for each nozzle in action. We have various tips and nozzles so that the correct diameter is allow selected. When dealing with the high pressures of Concrete sandblasting, the hose lines will require adequate strength and reinforcement. Because the air is pushing abrasive material in the hose’s inside diameter, it is essential to have the right size and durability
The proper time to do the blasting depends on the location and project. The exact distance of spray pattern for dustless and normal sandblasting depends on the pressure being used, the concrete matrix’s hardness, and the abrasive’s cutting ability. An experienced Concrete Doctors operator can quickly determine the nozzle position to produce the specified surface finish expected.
