Product certification reference: C11X7622
Objetive: Measurement of water flow capacity of drenotube® ∅300 under compression.
Test description: Half metre drenotube samples were placed in a double wall semi circular box section. The inner wall is a perforated semi circular plate allowing to pass the water through it. On the top of the box was a shaft sealed 530 x 280 mm hydraulic steel moving plate able to compress drenotube® longitudinally. Different pressures were applied and flow rates for a fixed gradient were recorded.
Test procedure: Customised.

Objetive: determine the compressive properties of drenotube® after oxidative ageing.
Test description: To carry out the test, the sample has been compressed until its collapse. The ageing that has been applied to the samples was 70º C for 14 days. Tests were conducted at 6 and 10 kN and data was recorded and compared with original samples.
Test procedure: UNE-EN ISO 604:2010 (compressive properties)

Certification Body: AITEX Textile Research Institute
Product certification reference: 2010GT0187
Objetive: Determination of the water flow capacity of the particles in their plane. The purpose of this test is to determine the flow capacity that
presents the ensemble of EPS particles, which are an integral part of the drainage system of the drainage geocomposite
drenotube®. This ensemble of particles replaces the traditional gravel, allowing the water filtering into the central drainage
pipe.
Test description: To carry out the test, the test zone of the device has been filled with “EPS GRAVEL” until it has occupied all the volume. Subsequently it has been under increasing load with gradients of 0.1 and 1.0 The test has been carried out placing the sample between two rigid plates. Unable to perform the test at 20kPa/1.0 because it has been impossible to achieve this gradient as a result of the high flow capacity. The test was performed between 200 and 1000 kPa

Product certification reference: 2010GT0207
Objetive: The purpose of this test is to determine the variation in compression properties of the drainage geocomposite DRENOTUBE®, after an hydrolysis ageing. For this purpose, the results of compressive properties obtained from original samples (as 2010GT0206 report issued by AITEX), are compared with the obtained results of compressive properties of previously aged samples.
Test description: To carry out the test in both cases (original samples and hydrolsysis aged samples), the sample is placed in a semicircular base which has been made for this purpose. The compression is done with a hardened steel plate which compresses the sample vertically. The dimensions of this plate are 29 x 30 cm. To carry out the test, the sample has been compressed until its collapse. The ageing that has been applied to the samples has been 60º, 70º and 80º C for 28 days each one.

Objetive: The purpose of this test is to determine the variation in compression properties of the drainage geocomposite drenotube®, after a microbiological ageing by soil burial. For this purpose, the results of compressive properties obtained from original samples, are compared with the obtained results of compressive properties of previously aged samples.
Test description: To carry out the test in both cases (original samples and microbiological aged samples), the sample is placed in a semicircular base which has been made for this purpose. The compression is done with a hardened steel plate which compresses the sample vertically. The dimensions of this plate are 29 x 30 cm. To carry out the test, the sample has been compressed until its collapse. Exposure time: 16 semanas / weeks Tª / Temperature: 26 ±1°C H.R / Relative humidity: 95 ±5% Soil was acclimatazed prior to use for 4 weeks at 28 degrees C and (97%±2)% RH Test conditions: Moisture content 60 % of SMC After exposure any soil remaining on the specimens was removed and all specimens, including the control specimens, were submerged in a ethanol-water solutions (70: 30) for 300 seconds. The specimens were then cleaned under running water, wiped with absorbent paper and left to dry and condition before carrying out the tensile test.

Calculation & Conversion
Find a practical conversion table in the range of drenotube® corrugated pipe operation. Also equivalences between units. Please Click here
This is to calculate the Flow rate and speed of water according to pipe diameter, slope and interior roughness of the corrugated pipe. Please send us and enquiry to send you Mannings drenotube® calculator.
Pressure acting on drenotube® in the ground equals to pressure caused by the weight of soil above the drenotube® + hydrostatic pressure caused by the weight of the water above the drenotube® + pressure caused by the transport load on surface of the soil (live vehicle load). Please contact our Technical Service in case you need particular figures. We will need some data to estimate the underground pressure acting on drenotube® drainage – Depth of installation, Nature of soil and live vehicle load. Is groundwater level above drenotube® ? Distance?
It is applicable to the speed of water at the bottom opening of the geotextile and also at the perimeter of the corrugated pipe. Please contact our Technical Service for a calculation.
