Concrete Slab Construction Process
The preparation of building a Sport Court is involves creating a proper foundation and for the post-tension concrete slab of the court. The “foundation” of the court’s slab is made up of three main components, the subgrade, subbase, and vapor barrier. The subgrade is the “earth” or area where the court will be built on. It is the existing soil/land where the area will sit. This area is first “graded” to level give the future concrete slab a proper slope, starting with the subgrade itself.
After the subgrade has been measured, leveled, and graded, the subbase is added. The subbase is a foundational base of support for the concrete slab that goes on top of the subgrade. The existing subgrade soil may be to weak, rocky, unstable, and maybe just not a proper foundation to support a concrete slab. This is where a different, proper subbase can be used to support the slab. For example, if the subgrade contains a lot substantially large rocks that do not allow for proper ground compaction or the slab will be used for the support of heavy loads, then it is necessary to use a subbase that is stronger then regular earth to support the load. Generally, the proper subbase material for a general purpose concrete slab is Aggregate Base Course (Commonly known as ABC). The subgrade should be compacted is possible and applicable. The subbase must be compacted.
The last foundational component necessary for the construction of a post-tension sport court concrete slab is a vapor barrier. A vapor barrier is a type of layer that goes between the subbase and concrete slab. Its purpose is to prevent vapor from the subgrade and subbase to travel up to the concrete slab. This is vital for sport courts because moisture that comes from the bottom of the slab, up and through the surface of the slab can cause the paint surface of the slab to “peel” and become unadhered from the court’s surface. The typical vapor barrier used for a concrete slab is a 10 mils polyethylene tarp. The tarp goes over the compacted subbase and should cover the entire subbase area.
Chainlink Fencing Construction Process
After the post-tension concrete slab has been built, the chain-link fence is the next process in the construction of a full Tennis court. Firstly fence post locations are measured following industry standards for chain-link fence construction. The court designer also has to decide on whether the light posts should be used as part of the chain-link fence framework itself (using light posts as fence posts in combination with the rest of the chain-link fence posts). After the fence post positions have been identified and marked, the holes for the posts footers must be dug. The fence posts holes should be dug with a slight angle towards the slab to allow the fence posts to be properly butted up against the concrete slab. Dirt removed from the digging process should be properly disposed of at a local landfill or other construction project in which the dirt material can be used.
The fence posts are usually purchased from the suppliers in longer sizes than what their installation sizes are. If this is the case, the fence posts must be measured and properly cut to the height that hey should have, including the depth at which they will be installed and the mark at which the posts are fush with the surface of the concrete slab. To reduce the possibilities of unchangeable sizing mistakes after installing the fence posts in their concrete footers, it is best to initially cut fence posts with an additional margin in measurement. It is better to have a fence posts that is a little taller than it should be, which can then later be cut to its prefect size once installed and set in its concrete footer.
After the fence posts have been cut and mark marked at the proper footer depth and the concrete slab’s surface level it is time to install the fence posts.
Resurfacing a court is the painting of the court. The reason that we do not call it “painting” is because a sport court’s surface is more than just pigment. It is a surface with special acrylic-polymer paint mixed with silica sand that results in a sport surface that is made to properly grip a players shoe and playing ball. It’s not just paint, but an actual playing surface made for playing performance.
The first step to resurfacing a court is to get a proper surface on the concrete itself for proper adhesion of the sport surface on the bare concrete. To do this, the concrete slab’s surface is floor sanded with a concrete 60-grit surface sander disk. After the surface is floor-sanded the court dust accumulated from the sanding is blown off.
The next step is to pressure wash the surface of the concrete slab to remove all dust that is still in the surface pours of the concrete and any other impurities that can cause poor adhesion of the playing surface with the concrete slab’s surface.
