Many people are still searching the internet for information on how to build a waterfall or koi pond. Unfortunately, there is very little information regarding professional construction. There are thousands of websites involved in marketing pond products to uninformed and unsuspecting customers.
The majority of these sites promote and advocate the use of rubber pond liners. Why? Because they sell them. Rubber liners are profitable, primarily because of the add-on products related to the pond liner industry best pedestal sumps. For example, when you construct your pond using a pond liner, you have no choice but to buy all of the related accessories such as a biofilter, special skimmers and drains, and the large variety of energy-sucking, inefficient, short-lived sump pumps.
Rarely do pond liner dealers or installers tell you the whole truth about the unpredictability of liners and sump pumps. Rarely do they acknowledge the truth about the vulnerability of liners after they are installed – whether it be attacks by rats, mice, ground squirrels, gophers, chipmunks or the sharp claws of animals that can puncture the liner in their attempt to get out of the pond after accidentally or purposely entering it. Animals burrow under the liner through the easy access of the loose rocks piled around the pond and waterfall. Against the coolness of the liner, they build their nests and raise their families that can then chew holes in the liner.
Over the past twenty years I have replaced countless leaky waterfalls and ponds constructed using rubber liners with concrete and rebar construction. In thirty years of building over 2,000 waterfalls and ponds, I have never had one crack or leak.
Liner advocates tell you their liner has a thirty to forty year warranty, but fail to mention it is against factory defects only. They don’t mention the other issues like rodents, heavy rocks stretching and ripping the liner, and damage from children with sharp sticks or garden utensils. I’ve seen it all!
Many water garden contractors will misrepresent the liner as the best construction material by saying concrete is expensive and it cracks. Yes, that is true, if you don’t build it properly using 3500 psi concrete and rebar 8 to 10 inches on center. Plus, they say the alkali poisons the water. That is true only if you don’t seal the concrete with a sealer after it is poured. Concrete construction costs 20-25% more than a liner, but it lasts for decades. You only have to replace one liner for the concrete pond to cost considerably less in the long run. In the past five years there have been scores of lawsuits against pond liner contractors and their clients win every time.
If your home has a basement you should be sure that you know about basement waterproofing. Basements are extremely susceptible to flooding, especially when the moisture and rain fall levels are high (like when the snow melts or in areas of the country where torrential downpours are common). Basement flooding can also be caused by water problems inside the house like leaking pipes. With your basement under the constant threat of water damage, you should be very interested in basement waterproofing methods.
The first step to waterproofing a basement after a leak occurs is to find out the exact source of the leak. External and internal basement waterproofing methods are effective and seem similar but they aren’t completely the same. Leaks that stem from structural integrity problems will have different solutions than leaks from household pipes or other internal sources.
There are three basic kinds of basement waterproofing. Interior sealants, interior water drainage and external waterproofing. You should look into each method of basement waterproofing to learn how best to ensure that your home isn’t at risk of severe water damage.
Interior Sealants aren’t technically basement waterproofing materials, but they can help you make do while you are working on other waterproofing methods. Usually an interior sealant is used to keep the atmospheric humidity levels in your basement down. The sealant can keep moisture from getting absorbed into the walls and floors of the basement. It can keep the moisture from spilling into other areas of the house as well.
Interior Water Drainage. Like interior sealants, interior water drainage isn’t technically a method of basement waterproofing, but it is usually used to help deal with basement water levels so most people have come to think of it as waterproofing. Usually interior drainage systems drain away most interior water by moving the water through the footers of the foundation and then out from underneath the basement floor. If you have a sump pump you can usually do this all by yourself. Just make sure that the drainage system will still be operational if the power goes off or if the sump pump fails temporarily.
Exterior Basement Waterproofing is the best method for basement waterproofing. This is the only basement waterproofing method to be recognized by the International Building Code as efficient enough to keep water from doing any intense structural damage to a building or home. Exterior waterproofing makes use of polymers or membranes that are used to waterproof the basement walls. These polymers can last thousands of years so they are seen as the best option for waterproofing.
