Geotextile membrane installation is easy and doesn’t require a lot of effort or a long time. For some people who have entered the world of geotechnics, they are already familiar with the term geotextiles.
Geotextiles are generally used in civil engineering projects, especially those related to geotechnical problems. Geotextiles themselves are textile materials that usually pass water safely and are then installed together with foundations, soil, rocks, or other geotechnical materials. It is an integral part of the structural system.
Various Steps for Geotextile Membrane Installation
Perhaps some people don’t know or understand the installation of a geotextile membrane. Especially for those of you who are laypeople and have not yet entered the world of geotechnical engineering. There are many types of geotextiles, based on the method used to combine ribbon filaments into a sheet structure. The first type of geotextile is non-woven and woven geotextile.
Woven geotextiles are made from monofilament, multifilament, fibrillated yarns, or pieces of film and tape. The weaving process for woven geosynthetics is the same as making ordinary textiles.
Non-woven geotextiles use advanced technology, where polymer fibers are pushed out and twisted continuously. Next, the mass of filaments becomes one by a mechanical process using hot pinpricks. Immediately, here are some correct geotextile membrane installations:
Geotextile Released Freely
The first installation, namely the geotextile, must be removed loosely without excessive wrinkles or folds. You must roll out the geotextile with the machine perpendicular to the pile axle as shown in the plan drawing. So the perpendicular and parallel directions on the machine must be opposite to each other.
Geotextiles Must Not be Dragged
The second step in installing the geotextile is that it must not be dragged through the mud on sharp objects that could damage the geotextile. So the backfill layer should be placed on top of the geotextile as best as possible. So that at least a layer 200 mm thick is between the steel chain wheel and the geotextile.
Mound of Soil Based on Manufacturer’s Recommendations
The next stage of geotextile membrane installation is to hold the geotextile in place until the cover embankment material has been determined and must be suitable for the soil mound based on the manufacturer’s recommendations.
Damaged Geotextiles mMust be Repaired by The Contractor
If the geotextile is torn or even has holes or the joints are damaged, it must be repaired by the contractor at no cost to the Works Director. The repair should include an additional geotextile of the same type placed over the damaged area. The patch should be sewn on all edges.
Embankment Construction Must be Symmetrical
Meanwhile, you must carry out embankment construction symmetrically at all times to prevent the collapse of the local bearing capacity under the embankment. So any backfill that you place on top of the geotextile must be spread immediately. Mounding of stockpiled soil over geotextiles is not permitted.
The Vibrating Compactor Must Not be Used
Things you must check when geotextile membrane installation. To produce an embankment up to at least 0.5 m of the embankment that has covered the bottom geotextile layer and at least 0.3 m of the embankment that has covered the next layer of geotextile above the bottom geotextile. Therefore you should not use a vibrating compactor.
Geotextiles in Pretension Before Deployment
Lastly, the geotextile must be pre-stretched before spreading using methods 1 and 2. So the choice of method depends on whether or not there are mud waves when spreading the first and second embankments.
If the mud waves, deposits arise when pushed on the first layer of geotextile. Then you should use method 1. However, a mud wave does not form during embankment during the pushing process on the first layer of geotextile.
So you must use method 2 from the beginning to the top layer of covered geotextile with a minimum thickness of 0.3 m. After making the work floor if you need it, you lay the first layer of geotextile using the transverse direction of the pile and sew it together. You stretch the geotextile manually to ensure that wrinkles do not form.
Those are the correct steps in the correct geotextile membrane installation. You can apply it, but if you still don’t understand, it’s a good idea to ask someone who has experience for help.
