Our Concrete Foundations Service

Every successful foundation project begins with meticulous site preparation and layout. Our process starts with a thorough evaluation of your construction plans and the building site. We clear and grade the land to create a stable, level base for the foundation. Our team uses precision instruments to accurately lay out the exact dimensions of the foundation according to the architectural drawings. We stake out the perimeter and interior load bearing points with extreme care. This step is critical, as the accuracy of the entire structure depends on a perfectly square and correctly dimensioned layout. We also coordinate with other trades to plan for the placement of underground plumbing and utilities.

The next step is the excavation and construction of the footings. Footings are the wide bases at the bottom of the foundation walls that distribute the building’s weight over a larger area of soil. We excavate trenches for the footings to the depth specified by the engineering plans, ensuring they are below the frost line to prevent shifting. We then build formwork for the footings and install steel reinforcement bars, or rebar, within the forms. This rebar provides the tensile strength needed to resist soil movement and prevent cracking. The quality and proper placement of the footings are fundamental to the stability of the entire foundation.

Once the footing forms are in place, we pour the concrete. We use a high strength concrete mix specifically designed for footings to ensure maximum durability. The concrete is carefully placed into the forms and consolidated to remove any air pockets. After the footings have cured sufficiently, we begin constructing the formwork for the foundation walls themselves. We use professional grade forming systems to ensure the walls are straight, plumb, and have a uniform thickness. We install all necessary window and door openings, known as bucks, as well as anchor bolts for attaching the building’s frame to the foundation.

Reinforcement and waterproofing are key components of our foundation wall process. We place a carefully engineered grid of horizontal and vertical steel rebar within the wall forms before the pour. This steel reinforcement is what gives the concrete walls the strength to resist the immense pressure from the surrounding soil. For basements, we also install a waterproofing system. This typically involves applying a waterproof membrane to the exterior of the foundation walls after the forms are removed. We also install a foundation drainage system, such as a French drain, around the perimeter to collect and divert groundwater away from the foundation.

The pouring of the foundation walls is a highly coordinated and critical event. We schedule the concrete delivery and use a concrete pump to efficiently and evenly fill the tall wall forms. Our experienced crew works the concrete as it is being poured to ensure there are no voids or honeycombing. We carefully monitor the pour to maintain the integrity of the formwork under the extreme pressure of the wet concrete. The top of the wall is expertly troweled smooth and level, ensuring a perfect surface for the home’s sill plate to rest on. Our precision and attention to detail during the pour guarantee a solid, high quality wall.

After the concrete walls have cured and gained sufficient strength, we begin the careful process of stripping the forms. This reveals the finished concrete foundation. We then proceed with backfilling, which is the process of placing the excavated soil back in place around the new foundation walls. We do this in controlled layers, or lifts, compacting each layer to prevent future settlement. We also ensure the final grade of the soil around the foundation slopes away from the house. This is a crucial step for ensuring proper surface water drainage and keeping your basement or crawl space dry.

Our service also includes the pouring of the basement or garage slab floor. We start by installing a layer of crushed stone for drainage and a vapor barrier to block moisture from rising from the ground. We then place reinforcement, such as wire mesh or rebar, and pour the concrete for the floor. The floor is expertly finished to be smooth and level, providing a durable and usable surface. Upon completion of the entire foundation, we conduct a final inspection and cleanup, leaving you with a perfect foundation that is ready for the framing carpenters to begin their work. Our commitment to 5 star service ensures a clean and professional job site.

A Homeowner’s Guide On Concrete Foundations in Pittsburgh

Common Concrete Foundations Questions

The foundation is the unseen hero of your home, providing the essential support for the entire structure. A well built foundation is critical for the safety, stability, and longevity of your investment. Homeowners and builders in Pittsburgh often have important questions about this crucial stage of construction. Here are some of the most common inquiries we receive about concrete foundations.

There are three primary types of concrete foundations used in residential construction: full basement, crawl space, and slab on grade. A full basement foundation involves creating a deep excavation and pouring concrete footings and tall foundation walls that form a full height room beneath the ground floor of the house. This is a very popular option in Pittsburgh and other northern climates. The main advantage of a full basement is the significant amount of extra space it provides. This space can be finished to create additional living areas or used for storage and housing mechanical systems like the furnace and water heater.

A crawl space foundation is a shallower version of a basement. The footings and foundation walls are constructed similarly, but the walls are much shorter, typically creating a space that is only a few feet high between the ground and the home’s floor joists. This space allows for access to plumbing and electrical wiring but is not tall enough to be used as living space. Crawl spaces are generally less expensive to construct than full basements because they require less excavation and concrete. They also elevate the house off the ground, which can be beneficial in areas with damp soil.

A slab on grade foundation is the simplest and often the most affordable type. In this design, the footings and the floor are created as one single, thick slab of concrete that is poured directly onto a prepared gravel base on the ground. The edges of the slab are thickened to create integrated footings. There is no space underneath the house. This type of foundation is common in warmer climates where the ground does not freeze deeply. While less common for primary homes in Pittsburgh, slab on grade foundations are often used for garages, sheds, and home additions where a basement is not necessary.

Preventing foundation cracks starts long before any concrete is poured. One of the most important steps is proper site preparation and soil compaction. The soil that the foundation will rest on must be stable and well compacted. If the soil is loose or improperly graded, it can settle unevenly under the massive weight of the house, causing stress that leads to structural cracks. A professional foundation contractor will ensure the subgrade is prepared to the correct specifications. The design of the footings is also critical. They must be wide enough to properly distribute the load over the specific type of soil at the building site.

The design of the concrete mix and the quality of the pour are also crucial for preventing cracks. A proper concrete mix will have the right balance of cement, sand, aggregate, and water to achieve the specified strength. Too much water in the mix can significantly weaken the concrete and lead to excessive shrinkage and cracking as it cures. During the pour, it is essential to consolidate the concrete properly using vibrators to remove any trapped air pockets. Cold joints, which are weak spots that can occur when one layer of concrete starts to harden before the next layer is poured on top, must be avoided through careful planning and execution.

Finally, proper reinforcement and curing are key to a crack resistant foundation. Steel reinforcement bars, or rebar, must be placed correctly within the footings and walls according to the engineering plans. The steel provides the tensile strength that concrete lacks, helping it resist the forces that cause cracking. After the concrete is poured, it must be cured properly. This means keeping the surface moist for a period of time to allow the concrete to hydrate and gain strength slowly. If concrete dries out too quickly, it is much more likely to develop shrinkage cracks. RMK Services employs all of these best practices to build strong, crack resistant foundations.

Rebar, which is short for reinforcing bar, is a steel bar used to provide reinforcement in concrete structures. Concrete is a material that has incredibly high compressive strength, meaning it is very strong under pressure and can support immense weight. However, concrete has very low tensile strength, which means it is weak when it is being pulled apart or bent. This weakness makes unreinforced concrete susceptible to cracking from forces like soil pressure, settlement, and thermal expansion and contraction. This is where rebar plays its critical role.

Steel, in contrast to concrete, has extremely high tensile strength. By embedding a grid of steel rebar within the concrete, we create a composite material called reinforced concrete. The steel and concrete bond together to create a structural element that is strong in both compression and tension. The rebar takes on the tensile loads, resisting the pulling and bending forces that would otherwise cause the concrete to crack and fail. This allows the foundation to safely handle the complex stresses it is subjected to from the weight of the house and the pressure of the surrounding earth.

In a foundation, rebar is strategically placed in the areas that will experience the most tension. This includes the bottom of the footings, where the foundation bends under the weight of the walls. It is also placed horizontally and vertically throughout the foundation walls to help them resist the lateral pressure from the soil pushing against them. The size, spacing, and placement of the rebar are carefully calculated by a structural engineer based on the specific loads and conditions of the project. Without proper steel reinforcement, a concrete foundation would not have the strength and durability required to safely support a home.

The timeline for building a concrete foundation can vary significantly based on several factors. The size and complexity of the foundation are the biggest determinants of the schedule. A simple, small rectangular foundation for an addition will take much less time than a large, complex foundation for a custom home with multiple corners and levels. The type of foundation also plays a major role. A slab on grade foundation is the quickest to install, while a full basement foundation is the most time consuming due to the extensive excavation, formwork, and multiple concrete pours required.

Weather is another major factor that can impact the construction timeline, especially in a place like Pittsburgh. Heavy rain can delay excavation and turn the site into a muddy mess, making it unsafe and difficult to work. Concrete cannot be poured in freezing temperatures without taking special precautions, as the water in the mix can freeze and ruin the concrete before it has a chance to cure properly. These weather related delays are common and must be factored into the overall project schedule.

Generally speaking, a typical full basement foundation for an average sized home might take anywhere from two to four weeks from the start of excavation to the completion of backfilling, assuming good weather. This includes time for excavation, forming and pouring footings, forming and pouring walls, allowing for curing time, waterproofing, and backfilling. A project manager at RMK Services would provide you with a detailed schedule for your specific project. We work efficiently to keep the project on track while never compromising on the quality and safety standards that are essential for building a solid foundation.

The frost line, also known as the frost depth, is the depth to which the groundwater in the soil is expected to freeze during the winter. When water in the soil freezes, it expands with incredible force. If a building’s foundation is placed on soil that is above the frost line, this frost heave phenomenon can cause serious damage. As the soil freezes and expands, it can lift the foundation upwards. Then, when the soil thaws, it settles back down. This repeated cycle of lifting and settling can cause the foundation to crack, shift, and become unstable, leading to major structural problems throughout the entire house.

The depth of the frost line varies depending on the climate. In colder regions like Pittsburgh, the frost line is much deeper than in warmer southern climates. The specific frost depth for a location is determined by local building codes, which are based on historical weather data. In the Pittsburgh area, the frost line is typically considered to be at least 36 to 42 inches below the ground surface. This means that the bottom of a foundation’s footings must be placed below this depth to ensure they are resting on stable, unfrozen ground all year round.

Placing footings below the frost line is a fundamental and non negotiable requirement of building a safe and durable foundation in our climate. It anchors the building to soil that is not subject to the powerful forces of frost heave. This ensures the foundation remains stable and stationary throughout the seasons, preventing the structural damage that can result from frost related movement. Any reputable foundation contractor like RMK Services will be intimately familiar with the local frost line requirements and will ensure your foundation is built in full compliance with all building codes for your safety and peace of mind.

A French drain is a simple yet highly effective system used to manage groundwater around a home’s foundation. It consists of a trench that is dug around the perimeter of the foundation, either on the exterior or interior. The trench is lined with a special filter fabric, filled with gravel, and contains a perforated pipe. The purpose of the system is to collect subsurface water that is moving through the soil towards your foundation. The water enters the perforated pipe and is then channeled away by gravity to a safe discharge point, such as a storm drain or a lower point on the property, or it is directed to a sump pump to be pumped away.

Whether you need a French drain depends on the specific conditions of your property. They are highly recommended for any home with a basement, especially in areas with heavy clay soil or a high water table, which are common in the Pittsburgh region. These conditions can lead to significant hydrostatic pressure, which is the pressure exerted by water in the soil against your foundation walls. This pressure can force water through even the tiniest cracks in the concrete, leading to a wet basement. An exterior French drain installed at the level of the footings is the best defense against this pressure.

An exterior French drain is typically installed at the same time as the foundation is being built and waterproofed. It is the most effective way to keep groundwater from ever reaching your foundation walls. An interior French drain can be retrofitted into an existing basement that is experiencing water problems. It works by collecting water that seeps in at the joint where the wall meets the floor and directing it to a sump pump. An expert from RMK Services can assess your property’s drainage, soil type, and water table to determine if a French drain is a necessary component for keeping your basement dry and your foundation protected.

The cost of a new concrete foundation is one of the most significant expenses in a home construction project, and the price can vary dramatically. The primary factor influencing the cost is the size and type of the foundation. A larger house requires a larger foundation, which means more materials (concrete, rebar, formwork) and more labor. As discussed earlier, a full basement foundation will be the most expensive option due to the large amount of excavation, formwork, and concrete required. A crawl space will cost less than a basement, and a simple slab on grade foundation will generally be the most affordable option.

The complexity of the foundation’s design also has a major impact on the cost. A simple square or rectangular foundation is much easier and faster to form than one with many corners, steps, or curved walls. The soil conditions at the building site can also affect the price. If the site has poor soil that requires extensive excavation and replacement with engineered fill, this will add significant cost. Similarly, if the site is on a steep slope, it will require a more complex and expensive stepped foundation and additional earthwork. Any required permits and engineering fees are also part of the overall cost.

Because there are so many variables, it is impossible to give an accurate cost estimate without detailed architectural plans and a thorough site evaluation. At RMK Services, we provide detailed, itemized quotes based on your specific project plans. Our estimates are transparent and comprehensive, covering all aspects of the foundation construction from excavation to backfilling. We use our experience building foundations in the Pittsburgh area to provide competitive and fair pricing. Investing in a high quality foundation is critical, and we are committed to delivering exceptional value and a product that will last a lifetime. We also offer free in person consultations to review your plans.

The consequences of an incorrectly poured foundation can be severe and can compromise the integrity of the entire home. If the foundation is not square or level, it will create enormous problems for every stage of construction that follows. Framers will struggle to build straight walls, leading to issues with installing drywall, windows, doors, and cabinetry. This can result in a cascade of cosmetic and functional problems throughout the house, from sloping floors to doors that do not close properly. These issues are very difficult and expensive to correct after the fact.

More serious problems arise from structural mistakes during the foundation pour. If the concrete mix is improper, if the reinforcement is placed incorrectly, or if the concrete is not cured properly, the foundation may lack the required strength. This can lead to major structural failures, such as large cracks, bowing walls, or severe settlement. A weak foundation cannot adequately support the weight of the house, which can result in sagging floors, cracked drywall throughout the interior, and windows and doors that become difficult to operate. These are signs of a serious structural problem that can be very expensive to repair.

In the worst case scenario, a foundation that is poured incorrectly can lead to a home that is unsafe to occupy. A bowing basement wall could eventually collapse, or severe differential settlement could compromise the entire structure. Repairing a failed foundation is a massive and invasive undertaking, often involving extensive excavation, hydraulic lifting of the house, and the installation of new support piers. This is why it is absolutely critical to hire an experienced, licensed, and reputable foundation contractor like RMK Services. The foundation is the most important part of your home, and it must be built correctly from the very beginning.
