Concrete Work
It typically takes 28 days for most concrete and mortars tocure to the designed strength. However, most mixes will continue to harden over time. Temperature, humidity and other factors can affect cure time and overall strength. Make sure to ask what your mix design can handle.
The minimum temperature should be 5 degrees, which applies to air, mix and substrate. This temperature should not only take place during the application, but up to 24 hours after application. Once the temperature drops below 5 degrees it will stop curing and could potentially damage the concrete cell matrix.
Proper surface preparation is just as critical as choosing the right mix design. For new concrete slabs, excavate the area to remove grass and black earth to the clay. Ensure that the excavated area is pitched in a direction where water will run away from the building. Mark the perimeter of the new slab with stakes and string a level line between them. This will help ensure the forms are level. Lay a gravel base in the excavated area 3-4 inches in depth. This will help with any water flow or substrate movement and prevent the concrete from buckling. Remember to allow enough depth for both the gravel bed and a minimum of 4” inches of concrete. Place forms in the desired area using wooden or metal forms, assuring that they are level and square and all corners are sealed so no material can escape once placed. Screw or secure the forms together and now you’re ready to pour!
In Canada, pouring concrete outside is a challenge. The Spring and Fall are the best times of year for pouring concrete using best industry practices.
Concrete Sealing
There are two main types of sealers: penetrating sealers, which penetrate into the pores of the concrete to provide long-lasting protection, and topical sealers, which form a protective film on the surface of the concrete.
Concrete sealers create a barrier that repels water, preventing it from seeping into the concrete and causing damage. They also resist staining by preventing liquids and contaminants from penetrating the surface.
The best time to seal newly poured concrete is after it has cured completely, typically within 28 days. This allows enough time for the concrete to reach its maximum strength and for any moisture to evaporate.
The frequency of resealing depends on factors such as the type of sealer used, the amount of traffic the surface receives, and environmental conditions. Generally, concrete surfaces should be resealed every 1-3 years for optimal protection.
Yes, concrete sealing can enhance the appearance of the surface by adding a glossy or matte finish, enhancing the color, and bringing out the natural beauty of the concrete.
Factors to consider include the type of concrete surface, environmental conditions, desired level of protection, appearance preferences, and the specific requirements of the project.
Yes, penetrating sealers penetrate the concrete substrate to provide protection from within, sealing up the pores, while topical sealers form a protective film on the surface of the concrete of exposed or stamped concrete, which is an acrylic style.
When sealing decorative concrete, it is important to choose a sealer specifically designed for use on coloured or stamped concrete to avoid altering the appearance or causing discoloration. A sealer with UV inhibitors may also be necessary to protect against sunlight fading.
To maintain the sealer's effectiveness and prolong its lifespan, it is important to regularly clean the concrete surface to remove dirt, debris, and stains. Depending on the type of sealer used, periodic reapplication may be necessary to replenish the protective coating.
The lifespan of concrete sealers varies depending on the type of sealer used, environmental factors, and maintenance practices. Generally, penetrating sealers last longer than topical sealers because the surface protection wears off. That’s why The Concrete Doctors has regular customers who seal every 1-2 years.
While concrete sealing can help prevent surface damage such as staining and spalling, it cannot prevent cracks from forming due to structural issues or settlement. However, it can help minimize the effects of freeze-thaw cycles and other environmental factors that contribute to cracking.
Some sealers may increase the slipperiness of the concrete surface when wet, especially glossy, or high-sheen sealers. However, slip-resistant additives are available that can be mixed into the sealer to improve traction. Often clients ask us to use sand which is great option!
Yes, concrete sealers can be applied to coloured or stamped concrete to enhance and protect the surface's appearance. However, to avoid altering the colour or texture, it is important to choose a sealer specifically designed for use on decorative concrete. This is where experience counts.
Before applying a concrete sealer, the surface should be thoroughly cleaned to remove dirt, oil, grease, and other contaminants. Any existing sealers or coatings should be removed, and the surface should be allowed to dry completely.
Mild temperatures above 5 degrees with low humidity and dry conditions are ideal for applying a concrete sealer. Extreme temperatures, high humidity, rain, or freezing temperatures can affect the sealer's performance and curing.
Some concrete sealing products contain volatile organic compounds (VOCs) or other chemicals that can be harmful to the environment and human health. It is important to choose low-VOC or eco-friendly sealers whenever possible and follow proper application and disposal procedures.
The drying and curing time for concrete sealers varies depending on factors such as temperature, humidity, and the type of sealer used. In general, the surface should be allowed to dry for at least 24-48 hours before light foot traffic and 72 hours before heavy use or exposure to water.
The process for applying concrete sealer typically involves cleaning the surface, allowing it to dry completely, applying the sealer with a brush, roller, or sprayer, and allowing it to dry and cure according to the manufacturer's instructions. Multiple coats may be necessary for optimal protection.
Concrete Mudjacking
Mudjacking, also known as slabjacking or concrete leveling, is a process used to raise and stabilize sunken or uneven concrete surfaces. It involves drilling holes into the concrete and injecting a mixture of cement, soil, water, and other additives beneath the slab. As the mixture fills voids and compacts, it lifts the concrete to its original position.
Mudjacking is suitable for a variety of concrete surfaces, including sidewalks, driveways, patios, and foundations, that have settled or become uneven due to soil erosion, poor compaction, or other factors. It is particularly effective for lifting concrete slabs that have sunk due to soil settlement.
Some benefits of mudjacking include cost-effectiveness compared to full slab replacement, minimal disruption to the surrounding area, quick turnaround time, and the ability to lift and level concrete surfaces without major excavation or demolition.
Mudjacking can provide long-lasting results, with many repaired surfaces remaining stable and level for several years or more. The durability of the repair depends on factors such as soil conditions, water management, proper installation techniques, and maintenance.

Mudjacking typically does not significantly change the appearance of the concrete surface, as the 16. Will mudjacking change the appearance of my concrete surface?Mudjacking typically does not significantly change the appearance of the concrete surface, as the repair is focused on lifting and levelling rather than altering the texture or colour of the concrete.
After mudjacking, it's important to monitor the repaired area for any signs of settling or movement and address any issues promptly. Regular maintenance, such as cleaning and sealing, may also help prolong the lifespan of the repaired concrete surface.
Concrete Repair
Concrete repair involves restoring damaged or deteriorated concrete structures to their original condition or improving their performance. This can include repairing cracks, spalls, or other damage using various techniques such as patching, overlaying, or epoxy injection.
Concrete repair is suitable for concrete structures that have experienced damage due to factors such as freeze-thaw cycles, structural movement, chemical exposure, or aging. It is often preferred over full replacement when the damage is localized, and the structural integrity of the concrete can be preserved.
Concrete repair offers several benefits, including cost-effectiveness compared to full replacement, minimal disruption to surrounding areas, preservation of existing structures, and the ability to address specific areas of damage without affecting the entire concrete surface.
The lifespan of concrete repair depends on factors such as the extent of damage, the quality of materials and workmanship, and environmental conditions. Properly performed concrete repairs can last for many years, especially when combined with regular maintenance.
Concrete repair techniques can be used on a variety of concrete surfaces, including driveways, sidewalks, parking lots, bridges, and building structures. The specific repair method will depend on factors such as the type and extent of damage, as well as the condition of the concrete.
Concrete repair can be environmentally friendly when performed using sustainable practices and materials. Repairing damaged concrete structures helps reduce the need for new construction, conserves resources, and minimizes waste.
The time required before the repaired area can be used depends on factors such as the type of repair and the curing time of any materials used. In many cases, the repaired area can be reopened to traffic or foot traffic within a relatively short period, typically ranging from a few hours to a few days.
Factors that can affect the cost of concrete repair include the extent of damage, the size and complexity of the repair area, accessibility, the type of repair method used, and local labour and material costs.
