Rebound cracks are predominately horizontal cracks that occur 2-3” below the top of your pool steps. It occurs when the excess gunite bounces off the wall upon application that has a low cement to sand ratio and is weak in strength. Upon immediate visual inspection, it is impossible to see any issue. As the pool ages and settles with time, the steps built with low cement content don’t have the strength to withstand the stress and the weakest areas crack. Usually, the crack runs horizontally under the step.
So for this, you need to get your pool plastered again or get it fully repaired by the company specializing in pool repair services. But before you seek professional help from a pool repair company, check out the reasons for pool cracks:
• INADEQUATE BEARING OF THE SOILS OR SOIL RELATED ISSUES – When the pools are built, no one is bothered to take into consideration the soil over which the pool is being built. When you consider all the construction material and the pool water, then a pool can weigh more than 450,000 lbs. The soil in the Texas region is very reactive and that is why the soil cannot withstand the weight of the pool until and unless the soil is properly prepared. Moreover, the construction efforts put in by the company specializing in pool repair in Houston are always in place to deal with the soil issues and avoid any future problem like this.
• LACK OF TENSILE STRENGTH – Inadequate tensile strength and improper placement of reinforcing steel can also cause pool steps to crack. The rebar installed in older pools varies on its placement. Often rebar is installed in larger than 10”x10” on center grid patterns which are bad. 8”x8” on the center grid pattern is standard in today’s pools.
• INADEQUATE COMPRESSIVE VALUES OF THE GUNITE – Guinte application is considered great and perfect in pool construction if all rebound and trimmings are thrown out of the pool during construction. However, if this is done the total cost of the construction would increase. The areas of the pool that have rebound in them have no compressive strength and the pool structure is weak in that area. Hence, do not throw any of that dead material, instead, wind it up on the pool floor, steps, and benches of the pool and spa.
If your pool is also facing rebound cracks, it’s time to think about a pool remodel or pool repair. Cracks in swimming pools must be addressed to prevent them from becoming worse, such as allowing the pool to lose water. Water loss may not appear to be a concern; however, any amount of water loss over a period of time can result in the major structural problem for the pool.
