The pond liners membrane is based on ethylene propylene diene monomer (EPDM) synthetic rubber, a highly flexible yet stable waterproofing membrane with a proven performance history in exposed applications. pond liners retains its high flexibility even in cold weather. It can easily be shaped to fit the unique contours of any pond. Pond liners shows outstanding resistance to the harmful effects of ultraviolet radiation (U. V. ), ozone and other environmental conditions. pond liners exhibits a high tensile strength and an outstanding resistance to puncture and, once installed, requires little or no maintenance. pond liners is specially formulated to be safe for exposure to fish and plant life in decorative ponds while resisting microbial and algae attack. It is safe for fish and aquatic plants. Pond liners black color gives a natural look that blends with the algae that frequently grows after several months. The black color also lends greater U. V. protection while giving the illusion of greater depth. 0. 045 inch thick.

What is EPDM? EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e. ketones, esters, and alcohols). 2. What is the maximum size sheet for EPDM membrane? Sheets as large as 50 feet in width are produced mostly for use in ballasted and mechanically fastened applications. Narrower widths are also produced to offer applicators greater flexibility in positioning membrane. Narrower sheets are also produced without factory seams (seamless) for use primarily in adhered and mechanically fastened applications. The major advantage of seamless material is the elimination of factory splice T-joints that occur when factory seams intersect with field splices. This reduction in T-joints significantly increases the potential for watertight performance by eliminating potential “water channels” into field splices. Both narrow and wide sheets are manufactured in varying lengths from 50′ to 200′. 3. What size liner do I need? The formula for sizing a pond liner is: (Pond Length’) + (2 x Pond Depth’) + (2′) = Liner Length’ (Pond Width’) + (2 x Pond Depth’) + (2′) = Liner Width’ So… if you want a finished pond that is 12′ long, 7′ wide, and 3′ deep; then using the formula above, the liner size you need is: (12′) + (2 x 3′) + (2′) = 20′ Long (7′) + (2 x 3′) + (2′) = 15′ Wide This basic formula will work for ALL pond shapes. 4. How Many Gallons of Water does My Water Feature Hold? Rectangular Ponds Length x Width x Average Depth x 7.48 = Gallons Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is… 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons Oval Ponds Length x Width x Average Depth x 0.8 x 7.48 = Gallons Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is… 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons Round Ponds Length x Width x Average Depth x 7.48 =Gallons Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons Streams Length x Width x Average Depth x 0.25 x 7.48 = GALLONS =Gallons Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons 5. How deep should I make my water feature? For fish ponds, a depth of at least 18″, or deeper is recommended. Healthy fish LOVE to move up and down, as well as side to side! For water gardens, the water feature should have a depth of at least 12″, or deeper. Check your local fence requirements (building codes) and freeze line depth. 6. How Big of a Pump Do I Need? Minimum pump size is determined by pond type, water volume, head height and friction loss. The minimum pump size recommendations are: Water Garden, Few Small Goldfish Circulate total pond water valoume every 2 hours. Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall. Fish Pond, Several Small Fish Circulate total pond water valoume every 1 hour. Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall. Koi Pond, Several Large Fish Circulate total pond water valoume every 3/4 hours. Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall. Calculating Head Height Dynamic head pressure is found by taking the vertical height of your waterfall; the distance between where your pump is (typically in the skimmer) and where your waterfall is, and adding the static head pressure (pipe and fittings) 1’ for every 10’ of tubing and 1’ for every elbow or “T” fitting. Example: 3′ (vertical height) + 2.5 (25′ of tubing) + 2′ (for 2 elbows) = 7.5′ of Dynamic Head Pressure Note:It is important to take into consideration while calculating how much flow will be at the top of your waterfall by accounting for the head height due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump. 7. What Size Tubing Do I Need? Tubing Size Efficiency GPH Minimum GPH Maximum GPH 0.5” < 300 60 420 0.75” < 720 300 900 1” < 1,200 700 1,500 1.25” < 1,600 900 3,200 1.5” < 2,600 2,000 4,400 2” < 4,800 3,000 6,800 3” < 9,000 6,000 14,000 4” < 21,000 14,000 28,000 6” < 42,000 33,000 60,000 About Half Off Ponds Customer service is our business.
