Renton Concrete Services is your go-to choice for all of your concrete slab needs. Whether it’s a patio in your backyard or a foundation that will stand the test of time, we have got you covered with quality concrete slabs to help make your dreams a reality.
A concrete slab is a flat and horizontal surface formed by pouring concrete. It has many uses as well as durability; concrete slabs are the base that supports all types of structures and open areas of your home or yard, such as a shed, patio, pool deck, or garage.
The concrete slabs we install at Slab King in Renton have been designed with the elements of Renton in mind, including its wet winters and rich clay soils, so your slab will be level, stable, and continue to function well for years to come.


We offer a range of concrete slab designs to suit different purposes and conditions:
Flat Standard Slab: Most residential construction is done using standard flat slabs with reinforcement.
Thick Edge Slab: Additional edge support is added when heavy load bearing is required (e.g., garage, etc.).
Post-Tensioned Slab: This type of slab has advanced reinforcement for extreme soil conditions.
Monolithic Slab: A foundation and slab are cast at one time, providing an efficient method.
Independent Floating Slab: An independent slab that will allow for settlement of the ground under it.
We work closely with each customer to select the proper concrete slab design for their project based on the intended use, the soil conditions they have, and the applicable local building codes.

We can do every step of the way, from providing you with a free quote to doing the final inspection to ensure that your project is done on time and completed at the highest level.
