Review the following frequently asked questions to learn more about the technical details, preparation, and maintenance involved in our concrete slab services. If you require further general guidance, please visit our general concrete repair FAQs.
For standard residential applications like patios, sidewalks, and shed bases, a concrete slab is typically poured to a thickness of four inches. This depth provides ample strength for foot traffic and light storage. However, if the slab will support passenger vehicles, heavy equipment, or a hot tub, our concrete slab services generally recommend increasing the thickness to five or six inches for enhanced structural integrity.
Yes, a properly compacted gravel sub-base is critical to the success of any flatwork project. A granular base promotes proper drainage, keeps moisture away from the bottom of the concrete, and provides a stable, even surface that resists the shifting caused by Ontario’s freeze-thaw cycles. We thoroughly excavate the topsoil and compact the gravel base as a foundational step in our concrete slab services.
The choice between wire mesh and steel rebar depends on the slab’s intended use and load requirements. Wire mesh is highly effective for minimizing shrinkage cracks and holding the concrete together in lighter applications like patios. Steel rebar offers superior tensile strength and is recommended for load-bearing slabs, driveways, and garage floors. We assess your specific project needs during the planning phase of our concrete slab services to determine the best reinforcement.
Concrete hardens quickly but cures slowly. You can typically walk on a new slab within 24 to 48 hours. However, it takes approximately seven days to reach 70% of its strength, at which point light vehicles or structures can be introduced. A full cure takes 28 days. Our concrete slab services include specific guidance on curing timelines to ensure you do not inadvertently damage the surface by loading it too soon.
Vapor barriers, or vapor retarders, are highly recommended and often required by building codes for interior slabs, garage floors, or basement foundations. They prevent ground moisture from migrating upward through the porous concrete, which can cause dampness, mold, or damage to interior floor coverings. If your project involves an enclosed space, we integrate heavy-duty vapor barriers directly into our concrete slab services.
While spring, summer, and fall are ideal, concrete can be poured in colder temperatures using specialized winter techniques. This involves using heated water in the concrete mix, adding accelerating admixtures, and insulating the slab with thermal curing blankets immediately after pouring to prevent freezing. Winter concrete slab services require precise timing and careful temperature management to guarantee structural integrity.
As concrete cures, it naturally shrinks slightly, which can cause stress and random cracking. Control joints are deliberate, straight cuts made into the surface of the slab. They create a weakened line that encourages the concrete to crack neatly inside the joint rather than randomly across the visible surface. Proper joint placement is a critical aesthetic and structural element of our concrete slab services.
Yes. Proper preparation is essential, so our team manages the entire excavation process. We dig out the organic topsoil, level the ground, install the required gravel sub-base, and responsibly remove and dispose of all excess soil and debris from your property. Our turnkey concrete slab services mean you do not have to hire a separate excavation contractor.
In London, Ontario, water in the ground freezes and expands during winter, pushing upward on structures. When it thaws, the ground settles. This cycle can crack or heave poorly supported concrete. Our concrete slab services counter this by using deep, compacted, well-draining granular bases and air-entrained concrete mixes that provide microscopic pockets for freezing water to expand into without breaking the slab.
It depends on the extent of the damage. Minor surface spalling, scaling, or hairline cracks can often be effectively repaired or resurfaced. However, if the slab is suffering from deep structural failure, significant sinking, or heaving due to a collapsed sub-base, a full replacement is the safest and most cost-effective long-term option. We evaluate the condition carefully during our concrete slab services consultations.
No, water should not pool on a correctly installed slab. During the formwork phase, our team carefully calculates and implements a slight grade—typically an unnoticeable slope of about one-quarter inch per foot—to ensure rainwater naturally flows off the concrete and away from nearby building foundations. Precise levelling and grading are fundamental components of our professional concrete slab services.
To maximize the lifespan of an exterior slab, we recommend applying a high-quality penetrating concrete sealer approximately 30 days after the initial pour, once it has sufficiently cured. Following that, resealing the surface every two to three years helps block moisture penetration, resists UV fading, and prevents oil stains. Ongoing sealing is a simple maintenance step we highly recommend alongside our concrete slab services.
Permit requirements depend entirely on the size, location, and purpose of the slab. Small backyard patios or garden shed bases generally do not require a permit. However, large structural slabs, garage foundations, or slabs poured near property lines and municipal easements often do. We can advise you on local building codes and municipal requirements when planning your concrete slab services.
Absolutely. Concrete does not have to be plain grey. Integral liquid colors can be mixed directly into the concrete before pouring, providing a uniform hue. We also offer decorative finishes such as exposed aggregate, stamped patterns that mimic stone or brick, and classic broom finishes for slip resistance. Custom aesthetics are a popular feature of our concrete slab services.
We actively monitor local weather forecasts before scheduling a pour. If light, unexpected rain occurs after the concrete is placed, we use protective waterproof coverings to shield the wet slab. Heavy rain on fresh concrete can wash away the top layer of cement paste, leading to a weakened, dusty surface. Our concrete slab services prioritize ideal weather windows to ensure flawless finishing.
Sinking, also known as settling, is almost always caused by poor sub-base preparation or soil erosion. We prevent this by removing unstable organic topsoil, laying a deep bed of compacted granular gravel, and ensuring adequate drainage away from the slab to prevent water pooling underneath. Proper base engineering is the most critical element of our long-lasting concrete slab services.
A floating slab rests directly on the ground without deep frost footings, moving slightly as the earth freezes and thaws. It is commonly used for detached garages, sheds, or patios. A foundation slab, or monolithic slab, features thickened edges that extend below the local frost line to provide rigid, unmoving support for permanent living structures. We provide concrete slab services for both engineering styles.
Winter maintenance is minimal but important. We strongly advise against using harsh chemical de-icing salts on exterior slabs, especially during the first year, as salt can cause the surface to scale and flake. Instead, use clean sand for traction and a plastic snow shovel to avoid metal gouging. Protecting the surface is an essential part of the care advice provided with our concrete slab services.
Yes, provided the slab is engineered for that specific weight. If you plan to install a hot tub, vehicle hoist, or heavy machinery, you must inform us during the planning phase. We will adjust the concrete slab services to include a thicker pour, stronger concrete compression strength (PSI), and heavy-duty steel rebar reinforcement to safely support the concentrated static load without cracking.
Preparation is simple. Ensure that the project area is clear of personal items, patio furniture, and vehicles. Identify any known underground utilities, sprinkler lines, or dog fences before our excavation team arrives. Providing a clear access path for the excavation machinery and concrete delivery trucks helps ensure our concrete slab services proceed efficiently, safely, and entirely on schedule.
