Rebar is basically a reinforcing steel bar used for providing support to concrete structures. Rebar is used for supporting swimming pool concrete structures; it can be said that it is one of the most essential swimming pool building materials. A rebar is a bendable structure and thus it is used for constructing pools of different designs. It is used even while making pool steps. Read through the discussion below to know more about rebar requirement for San Antonio pool construction.

Rebar Size and Spacing

Pool builders use No. 5 rebar for constructing swimming pools. A No. 5 rebar comes with a diameter of 0.625” and it weighs between 1,000 and 1,100 lbs. For increasing a pool’s structural strength, it is extremely important to maintain accurate rebar spacing. For the majority of the locations, ideally there should be a gap of 2.5” between 2 adjacent rebars. However, the building codes in your area might suggest otherwise. Thus for determining the correct rebar spacing for the area in you reside in, you should seek help from an experience San Antonio pool builder.

Rebar Grading

The market houses rebar of three different grades; they are: grade 75, 60 and 40. The rebars of grade 40 are used for constructing swimming pools. A rebar of grade-40 is capable of yielding strength of as much as 40,000psi. Their code permitted strength, on the other hand, is 20,000psi. Here, PSI stands for per square inch.

Rebar Installation

One of the most essential steps of San Antonio pool construction is rebar installation. The size of a rebar should be similar to that of a regular steel bar. Their spacing should be decided according to the structural plan of the swimming pool. The rebar’s protection coverage should be mentioned in the pool’s structural plant or in the local code.

The pool construction workers tie the rebars in a place to prevent occurrence of any kind of movement or vibration. The rebar should be placed in such a way so that it enables proper encasement in shortcrete/gunite (concrete that get projected into the pool’s surface at an extremely high velocity). The installer will fail to encase the rebar properly only if there’s an issue with the reinforcement of the concrete. However, you will not face such problems if the entire construction work is carried out by a well known San Antonio pool construction company.
