Let me start by saying I have a tremendous respect for landscape architects and their dedication and valuable contributions to the swimming pool industry. My goal here is to bring attention to companies that advertise as swimming pool architects who overlook best management practices that can compromise swimming pool structures.
Yes, it’s very important for a landscape architect to know municipal ordinances and where the sun rises and sets when designing a swimming pool. It’s also important to know where the swim-out and the dive rock should be placed. But shouldn’t you expect more from your landscape architect or pool designer? What about safety, proper equipment function, and construction techniques? Just because a landscape architecture firm has designed a lot of properties that included a swimming pool doesn’t necessarily make them experts who can manage or build your luxury swimming pool.
There are some NJ landscape architecture firms who claim that they can save clients money by managing their swimming pool project. They tell the client that they can send the job out to bid, get them the best price, and manage the construction for a percentage of the swimming pool construction costs. In many instances, the low bid pool builders (who will give the landscape architect that “best price”) sub contracts most of the construction out to smaller companies. So that means the sub contractor of the low bidder is being managed by a landscape architect who more than likely has no construction experience. Does anyone else see the problem with this?
If you’re going to spend fifty thousand dollars on a swimming pool and then add a fifteen thousand dollar waterfall or a twenty thousand dollar vanishing edge, I’m sure you want to enjoy it for many years to come. That’s questionable at best, given this scenario, As the degree of difficulty in luxury pool building continues to rise and the economy continues to remain weak, it has created the perfect storm in the luxury swimming pool market. Low and mid-market pool builders now claim to be high-end builders. They are running to the luxury pool market (because it’s the only pool market left) despite lacking the necessary skills to build these extremely involved structures! In addition to that there are certain landscape architects who claim to have experience managing swimming pool construction. It’s become confusing for the consumer, and unfortunately the end result is a lot of failing pools.
Swimming pools have been the dominant feature in back yard designs for many years. Over the last ten years we have built some of the most intricate structures garnished with some of the most lavish finishes. Unfortunately, we have also seen a larger number of failures in structures and finishes due to poor construction techniques. Here are five of the thirty issues that will ruin your swimming pool which most landscape architects fail to address in their design specifications:
Soil Stability – The failure of many pools and patios stems from the soil on which the structures are built. On all the landscape architecture plans we have bid on in the last ten years, I have yet to see one plan with any specifications regarding poor soil conditions.
Rebound – What is rebound and why will it destroy your pool? During the gunite installation material is pneumatically applied to create the pool shell. During the application, material that does not bond accumulates on the floor of the pool. This material is called rebound. Rebound should be discarded because it no longer contains structural qualities, but many pool companies don’t discard this material. They simply shovel the loose material into the walls and “flash” over it with fresh gunite. Once the material hardens it forms weak nonstructural pockets which can compromise the structural integrity of the pool vessel. This practice is against best management practices, but it is still a widespread problem in the industry.
Groundwater – How can groundwater compromise the inground swimming pool vessel? Gunite needs 28 days to properly cure, but the first 48 hours are the most crucial. Fresh gunite that is exposed to groundwater can be structurally compromised. As the water infiltrates the newly applied gunite, it basically washes out the concrete and leaves the weakened aggregate behind. The problem with this usually becomes apparent several years down the road when the homeowner decides to upgrade the pool plaster and drains the pool. Once the pool is drained, the pressure relief plugs which normally allow the groundwater to enter the pool vessel and reduce the pressure on the pool shell are rendered useless. If the groundwater reaches weakened gunite before the pressure relief plugs, the pool will crack under pressure where the groundwater compromised the gunite during installation. In other words, a cosmetic upgrade becomes a difficult structural repair.
Improper Sealing- Most companies don’t properly seal their pools, and some don’t seal at all. Some use generic sealers that only deal with positive water flow but fail to address the negative flow of water through the gunite shell. This can lead to plaster or tile damage or, even worse, the structural failure of the gunite.
Pump Size and Function – Undersized pumps in a spa will ruin the whole experience. What’s the right size pool pump for your spa? Spas are getting larger and more elaborate, and there isn’t much worse than getting in your spa and having weak jets. Ok, a cold spa would definitely be worse, but you can easily fix a heater. For pumps, it’s very expensive to have to redo the plumbing if the pump and piping is undersized.
The economy is still hurting and the mid and low swimming pool markets have been annihilated, so everyone wants to build luxury pools. Meanwhile these luxury swimming pools are getting more intricate and harder to build, and your everyday pool company is not capable of building these extravagant structures. Given the climate of this perfect storm, it’s extremely dangerous to let landscape architects who don’t have the proper build experience manage your swimming pool construction. While having a landscape architect is so very important (that’s why we have one on-staff), someone with the proper pool building experience must oversee construction to ensure the safety, durability and reliability of the pool. In my years in the pool industry I have never seen specifications come out of a landscape architecture office that address essential best management practices. Without these specifications, it’s easy for swimming pool contractors and subcontractors to make mistakes or drop their price, earn a bid, and do a half-hearted, poor job without the landscape architect ever realizing what’s going on. It’s a scary situation, and these 5 issues are just the tip of the iceberg.
