Pond Liner Calculator
In this pond liner calculator article, we answer the following frequently asked questions
1. How is a dam liner calculated?
The formulae adopted depends the shape of the water pan. The water reservoir’s dam liner is calculated differently for a circular or oval water pan vis a vis that of a square/ rectangular one. Similarly, a square water tank has a different formulae from a circular one. A water pan with slanting edges has a different formulae from that with straight edges. Whether the water reservoir or tank is for irrigation, domestic or industrial application, the formulae is the same
I. Square/ rectangular water reservoir or tank pond liner calculator
a. Square/ rectangular pond liner calculator for straight edges: Total length in meters: (length + 2depth + 2meters). Total width in meters: (width + 2depth +2meters). The additional 2meters on each side are for the overlap which is tucked in a trench for water reservoirs. For tanks, it’ll be 0.5M. Multiplying the total length with the total width gives the pond liner area in meters
Tucking is in a trench all around the water pan
b. Square/ rectangular pond liner calculator for slanted edges: Total length in meters: (base length + 2slanting depth + 2meters). Total width in meters: (base width + 2slanting depth +2meters). Multiplying the total length with the total width gives the pond liner area in meters
II. Circular pond liner calculator
Diameter + (2height/ depth) + (1meter). The 1meter is the external allowance that goes outside the tank as shown in the image below
2. How do I calculate how much pond liner I need?
The size of the pond liner is according to the water pan or water tank area. The size of the water pan or tank is by volume, shown as; length by width by depth/ height. The liner size is by area, shown as; length by width. For this conversion, the formulas shown above work
The larger the water pan or tank, the larger the pond liner required
Dam Liner Company In Kenya
Grekkon Limited is the foremost dam liner company in Kenya. From material selection, to welding and installation, our professional teams train growers on all these aspects. It ensures that they make the right choice and why. This is according to the size and nature of their irrigation water reservoirs and tanks. These dam liners in Kenya are UV treated, HDPE geomembrane material in varying thicknesses and weights as tabulated below
Liner Thickness | Liner Weight/ M SQ |
0.5mm | 460g |
0.75mm | 880g |
1mm | 910g |
The UV treatment reduces radiation damage which is high in tropical countries
Dam Liner Prices In Kenya
Our dam liner cost in Kenya is broken down into; material, welding, and installation. Once a grower procures a dam liner, s/he will have it welded if the width exceeds 8M. If the farmer chooses for us to install, then the cost of installation applies.
Liner Thickness | Material Cost (KES) |
Welding Cost (KES) |
Installation Cost (KES) |
AMOUNT (KES) |
0.5mm | 220 | 25 | 25 | 270 |
0.75mm | 300 | 25 | 25 | 350 |
1mm | 380 | 25 | 25 | 430 |
Dam Liner Installation
Our dam liner rolls are 8M wide. So for any width beyond this, the additional size has to be welded on. Welding is carried out fully in the ware house for small liners, and partly in the field for large liners. This is to reduce bulkiness during transportation to site
When installing a dam liner in a reservoir, trench round about the reservoir. This anchor trench is where the liner will be tucked for support. The diagram below illustrates the trench dimensions
The video below shows a farmer in Nandi county recounting the benefits he has received 2 years later after having his dam liner installed by Grekkon Limited

- How to select the right dam liner according to ; the reservoir size, surface texture, and one’s budget
Greenhouse Paper In Kenya
Grekkon Limited’s greenhouse paper in Kenya is of various rent characteristics. These characteristics determine it’s overall performance on the crop. The paper choice is the same irrespective of the greenhouse type by shape, or by structural material. Our greenhouse paper price in Kenya is Kes 96/M sq irrespective of the polythene properties.
Greenhouse Paper In Kenya; Properties
- Thickness. 200 microns/ 0.2mm
- Colour . Clear or yellow
– clear paper allows more light. This is good for fruiting crops such as tomato, strawberry, capsicums, and peppers. This is because more light has higher photosynthesis, which equates to more food for the plant. It is necessary for bi-color or multi -color flowers to enhance the different colors
– yellow paper will be for leafy vegetables, herbs, spices, and mono color flowers. These require less food as they are not fruiting
3. Width 5.5M, 8M, 16M. This not split but supplied as such to the grower
4. Roll length of 100M. The roll is cut as per client’s ordered length
5. UV treated. UV treatment blocks off excess UV light which in turn enhances the greenhouse paper lifespan. Our UV treatment is for 3 years/ 36 months. This warranty is on the paper
6. Anti-drip properties. Anti drip treatment prevents dew drop lets from forming on the greenhouse paper. Dew formation is as a result or crop respiration which releases moisture from the plant. Dew droplets falling or crops in the greenhouse pr-dispose the crop to fungal infections. The droplets also refract light, limiting the amount of light falling on the crop
How to choose your greenhouse polythene
- By crop. Is it a leafy or fruiting vegetable? Is is s mono or bi/ multi-coloured flower? This determines the paper color
- By width. There are different widths to choose from based on your greenhouse structure size
When the greenhouse paper tears, we provide a greenhouse repair tape that has the same characteristics as the greenhouse paper

The rain hose pipe price is not a good cost comparison to either drip or sprinkler irrigation. Rather, consider the set up and operational cost per acre under each method of irrigation
Rain hose works well with crops that thrive under sprinkler irrigation. Examples are; onion, garlic, cabbage, traditional vegetables, leafy vegetables and others. Crops that are susceptible to fungal infections if the leaves remain wet for long are irrigated with drip. Examples are; green beans, potato, strawberry, tomato, capsicums, peppers and others

Irrigation Company In Eldoret
The story of an irrigation company in Eldoret begins five years ago. In 2017, two Kenyan agri-prenuers came together to establish an irrigation systems firm to serve small to medium scale commercial farmers in Kenya. This was by providing tailored professional irrigation systems set up solutions that were within these farmers’ budgets. At the same time, improving the clients’ overall yield, and income from farming. The motivation to focus on this niche was because of the presence of large international irrigation service providers. Their clientele were the large ornamental, cereal and vegetable growers. Smaller growers had to fend for themselves because they were never a priority for these large corporates.
The other objective was to do further by offering expert irrigation, greenhouse, water pumps, and dam lining expertise. This is to small scale to medium scale commercial farmers, who had no professional entity to consult for such. It was through physical site visits to carry out assessments, provide advice, and carry out irrigation project reviews afterwards. And so, Grekkon Limited – Irrigation Hub was born.
The headquarters are Nairobi, Kenya’s capital. In April 2018, Grekkon Limited opened Eldoret irrigation hub along Kapsabet road in Kaburwa area within Eldoret municipality.
In mid-2021, the company opened a sub-branch in Eldoret town central business district. This is to serve farmers picking none bulky items such as irrigation fittings and accessories. The new sub-branch is located in Sugarland plaza, along Oloo street.
The irrigation company in Eldoret serves growers in; Nandi, Usain-Gishu, Bungoma, Trans-Nzoia, West Pokot, Turkana, Elgeyo Marakwet, and Baringo counties. These counties have varying climatic conditions and weather patterns. Those in the south are green with predictable rain patterns, hose in the north are arid and semi-arid locations.
