What is a Concrete Foundation?
A concrete foundation is essentially the bottom layer or structural base of a building and transmits the weight (load) of the structure onto the ground. It also gives you a solid surface to build from, as well as protects against moisture damage, settlement, and other forms of movement. A well-designed and constructed concrete foundation is crucial for a structure to be safe, stable, and last as long as possible.
Foundation work in Renton is very different than most areas due to the high amount of clay soil, high water table, and heavy rainfall. Therefore, we have extensive knowledge and experience and pay great attention to detail on all projects.
Concrete Foundation Design: Engineered for Your Project
We custom-design each concrete foundation based on multiple critical factors:
Renton Soil Conditions: Since the local soil of our region is composed primarily of clay that expands and contracts depending upon the amount of moisture present, we consider these soil conditions as part of our designs by incorporating suitable reinforcing elements and types of foundations.
Building Code Compliance: We maintain up-to-date knowledge of all applicable building codes in Renton and King County so your foundation can meet or exceed any building code regulations.
Structural Requirements: The type of foundation needed will vary depending upon the size, weight, and intended use of the building. Therefore, we design a foundation specifically for your building.
Weather-Related Considerations: As heavy rainfall, periodic freezing, and moisture management are the primary weather-related issues we face in the Renton area, these weather conditions are considered in our designs.
Budgetary Constraints: While we strive to remain within your budget for the construction of your foundation, we do not compromise the structural integrity of the foundation.
When necessary, our team collaborates with structural engineers to determine an optimal foundation design for your specific project and site conditions.
Concrete Foundation Installation Process
- Preparation of Site and Testing: The first stage of the process involves taking soil samples to determine if the soil will be able to support the weight of the house; conducting a site survey to determine the lay of the land and how much work needs to be done to create a flat area that can accept the weight of the home; removing all debris (clearing); and leveling the ground (grading) to provide adequate drainage so that water does not accumulate around the perimeter of the home; and to create a solid base upon which to build the home’s foundation.
- Digging: Once we have the information necessary to complete the site preparation phase, we then dig the site down to the appropriate depth to accommodate the size and type of footings and slab we need to install.
- Footings Construction: We then pour and cure high-quality concrete into the footing forms and set the reinforcement bar in place for added strength to the footing.
- Forming Foundation Walls: Next, we form the walls using high-quality materials and forms that meet our specifications. In addition, we also include the placement of the reinforcement bar and make provision for plumbing and electrical lines, as well as apply waterproofing when necessary.
- Preparing Slabs: Prior to pouring the concrete for the slab, we compact the gravel base; lay a vapor barrier on top of the gravel base; complete the plumbing rough-in; and set the reinforcement bar in place.
- Pouring Concrete: Once the preparation work has been completed, we pour the high-quality concrete into the prepared areas and finish the surfaces to the desired smoothness and level.
- Curing and Protecting: After the concrete has been poured, we take the necessary steps to ensure it is cured properly and protected from the elements so it develops its full strength and durability.
- Exterior Waterproofing and Drainage: Finally, we install exterior waterproofing and drainage systems, carefully backfill the area to prevent any potential damage to the foundation.
We manage every step with precision, ensuring your foundation is strong, durable, and built to last.
Concrete Footings: The Foundation's Foundation
Footings distribute the weight of your structure to prevent settling and failure. They’re wider than the foundation walls or piers they support, spreading the load across a larger soil area.
Spread Footings: These are typically used to support individual columns or piers and help to distribute the point loads associated with these structures.
Strip Footings: This type of footing is commonly used in residential construction to support continuous walls of the home.
Raft Foundations: In this type of footing, the entire footprint of the building rests on the footing and is often used when the soil has very low bearing capacity.
Stepped Footings: Used to navigate sloping ground while maintaining the required depth of the footing.
Regardless of which type of footing is being installed, all footings are engineered based on the soil’s ability to bear the load, the loads imposed by the structure, and the applicable local codes. We also ensure that all footings meet the minimum required depth (in Renton, typically 18-24″ below grade), have sufficient width, and provide adequate reinforcement to meet the needs of each specific project.
Dealing with Renton's Soil Challenges
Renton’s clay soils present unique foundation challenges:
Soil Expansion/Contraction: Soils made from clay expand with increased moisture and decrease in size as moisture decreases. Reinforced methods of construction and designing the foundation to allow for these movements are implemented.
Drainage: Clay soils do not drain well. Grading to prevent water accumulation, installing drainage systems, and incorporating waterproof measures into the structure are used to manage water.
Capacity to Bear Loads: Soil bearing capacity is tested to determine how much weight can be applied, and then, the foundation is designed according to its bearing capacity; in some cases, a larger footing or an alternate type of footing may need to be utilized.
Proper Compaction of the Fill and Base Materials: Proper compaction of the fill and base materials is necessary for stability. To properly compact, we utilize the correct equipment and testing to establish if the material has achieved the required density for structural integrity.
