Koi Pond - Dispelling Myths About Concrete

What do some liner promoters and salesmen say about professional pond installations using concrete and rebar, plus mortar to hold the rocks? (1) 'One challenge with concrete and mortar construction is regarding cement alkali leaching out for the effort after construction, poisoning the pond water with high alkalinity. It also leaves unsightly white deposit build-ups at the points of exit and on leading of rocks associated with waterfall.' NOT TRUE! If the concrete you use to pour the shell is a 7-sack mix with 40% pea gravel and stealth fiber mix, the concrete is so dense that no leaching can even occur. Also, because of the density of the concrete, it is not only just waterproof, but stronger than normal 5-sack mix used to pour driveways, patios and sidewalks. Finally, if you coat the finished surface with Thoro-seal, among the non toxic concrete sealers, it cannot leach. (2) 'When make use of mortar mix to secure the rocks in a waterfall, the water that soaks into the porous mortar joints, leaches out alkali and phosphorescence that poisons the pool. TRUE in the past, but not anymore. Regular mortar is porous, allowing water to pass through, dissolving and collecting the cement residue. This had been a major concern of mine for numerous. After the completion of a waterfall, I would have to run the waterfall for two or three weeks, shutting it off every 4 or 5 days, and acid-clean the white alkali residue off the rocks that had built up. Then, when we were finished, we will have to acid clean and rinse out it. Twelve years ago I discovered a secret formula may well render the mortar mix non porous and waterproof. It also makes regular mortar mix three times stronger. It is produced by adding one 45# bag of thinset (used to apply porcelain tile to a shower wall) to two bags of type S mortar mix. Once it cures, it becomes so dense, it is totally waterproof and won't leach any alkali after it cures (3 to 4 days). In addition, this mix is indeed so strong in its holding ability that after it cures, a sledge hammer can be remove a rock. In most cases, the rock breaks up before coming free of the secret formula mortar. It is not waterproof, but it bonds very well with all types and textures of rocks. It will provide a watertight barrier that comes in handy when building rock damns in the waterfall. The main feature of my special formula, is that it allows for far more creativity. You can easily raise the water level above the confines of the concrete shell without water leaking through the mortar joints, just like the case of regular type mortar preparation. This special mix is not for sale in the stores, and not will be, because I give the formula away cost! This discovery has revolutionized the effectiveness of mortar mix and its capability to bond, waterproof, and stop alkali leaching. A Dramatic Test A 4,000 gallon damages was converted into a concrete koi pond with two large waterfalls, held together with my new mortar mix, and an 8' x 12' area. The rocks surrounding the island, were also held by the formula. Once the project was completed, all of the surfaces presented a quick, mild acid wash, as well as the pond was filled and dechlorinator was added. The next day, $3,000 worth of my own private koi fish were transferred into the concrete koi pond. They both swam calmly around the island, inspecting every nook and cranny. None of these experienced any stress to begin with remained of temporary quarters for 90 days with no incidents. If it dramatic demonstration was inadequate to convert the skeptics, nothing might. So exactly what is the bottom level? Pond liners cannot be guaranteed in order to not leak, with regard to myriad of reasons. Concrete and rebar ponds, if built properly, will stay leak-free for decades, if not generations. You be the judge. You are the one investing your dollars and time into the software.
