FEATURE Commercial Swimming Pool Renovations Do’s and Don’ts By Shawn Still Association of Pool & Spa Professionals (APSP) – Georgia Chapter >> Georgia is the only state in the southeastern U.S. that does not have a uniform, statewide code for swimming pools. Therefore, counties should consider a number of factors when seeking contractors. 80 Swimming pool renovations break local government budgets across the country, and this trend continues to grow in Georgia. The reasons for cost overruns vary ranging from structural repairs to hydraulics to compliance with changing state and federal building codes. In addition to the growing number of unforeseeable expenses, there is no uniform commercial code in Georgia, with 27 of 159 counties following their own standards. The confusion for contractors and public health officials over the current code requirements, especially as it relates to the Virginia Graeme Baker (VGB) Act and the APSP/ANSI-7 Anti-Entrapment Standard, often leads to unqualified companies performing renovations. There are nine major phases to constructing a new pool: dig; plumb; steel; gunite; tile; coping; deck; plaster; and equipment. When working with a clean slate the margin of error is small. In renovation, particularly in pools more than 20 years old, there may be nine phases in addition to many more. Gutters crack or shift, decks heave, pipes are too narrow to meet current flow rate requirements, and interior finish options vary widely based on budget and longevity. Here are a few highlights to consider: Resurfacing: This is the most common renovation endeavor for commercial pools, whether using plaster, quartz, pebble or is a last resort situation, paint. The specification provided to the contractor should always require that a bond coat be sprayed or rolled over the existing surface once all loose or hollow substrate material has been removed. If the existing surface is only acid etched, count on the new surface debonding in a few areas within 12 months. If painted, then it must be first sandblasted back to the cementitious substrate before proceeding with the rest of the prep work. When the pool has more than two layers, even if properly bonded, it is a good idea to chip out back to the original gunite/concrete substrate because the added thickness of the new surface material will make all penetrations such as floor returns and lights, as well as all tile, look and feel very recessed. 1. GEORGIA COUNTY GOVERNMENT The life expectancy and warranty for these surfaces should follow these guidelines: a. Plaster: seven to 10 year life expectancy, one to two year warranty, depending on if drained in the off-season. Thickness one-fourth to three-eighths of an inch. b. Quartz: 10 to 15 year life expectancy, five to 10 year warranty. Thickness three-eighths to one-half of an inch. c. Pebble: 15+ year life expectancy, five to 10 year warranty. Average thickness five-eighths of an inch d. Paint: one to three year life expectancy, no warranty. In a balanced water chemistry environment, these finishes should last until the maximum range or beyond. National studies have shown that the cost to operate a pool year round is the same as winterizing with a safety cover. These same studies have shown that the most expensive way to operate a pool is to drain it at the end of each season and refill in the spring, due to the high cost of water, chemicals, and degradation to the surface. Balanced water chemistry should never be based strictly on pH, chlorine, alkalinity and calcium hardness, but rather a combination of all of these factors to be in range of the Langelier Saturation Index (LSI). The National Plasterers Council believes that in order for water to be considered balanced the LSI range must be between 0.0 and +0.3. The LSI assigns factors to TA, CH, water temperature and pH, which combine to give a target reading. Below 0.0 is acidic and above 0.3 is scale forming, or alkaline. Tile replacement: The cost to preserve waterline and racing lane tile is about half the price as to remove and replace. If multiple layers of plaster have already been installed, then the best course of action is to remove, brown coat, and set new. Installing tile over tile is a bad practice because the glaze on the surface of the tile does not allow the mortar to properly bond. The new tile should be set so that the face of the tile will allow the new interior finish to be applied flush without bulging or recessed under it. Main drains: The simplest way to explain the VGB Act and the ANSI-7 Anti-Entrapment Standard is to follow the guideline that the diameter of the suction pipe must be 1.5 times the 2. 3.
