A retaining wall can fail long before the blocks or concrete lose their structural integrity, primarily because trapped water has no escape route. This demonstrates the critical difference between a wall that suffers from hydrostatic pressure due to trapped water and one strategically designed with proper drainage features, including...

Here's an excellent video from Florian (follow) that shows charged water on the left and neutral water in the right. This is a visual confirmation of two known effects; Electrostatic induction and dielectric relaxation time. Electrostatic induction is like when a hair-rubbed balloon sticks to the wall, despite the wall being neutral; the balloon causes charges in the wall to polarize so the wall side near the balloon turns negative and the other side of the wall is positive. That's electrostatic induction and that's why you have raindrops that stick to a car window for hours of wind and gravity, rain has a small negative charge. Wouldn't work with tap water. Now, if you remove the balloon, the wall doesn't return to a neutral state immediately. It'd happen quickly if we had a balloon on the other side of the wall, but by itself this can take seconds, minutes, hours or even days, depending on the material and thickness. Glass is quite slow, and you can see the electric forces holding each other will hold off gravity for some time; and that the water greatly prefers not to be broken off, water is like an uncountable number of those walls in series, and they all cling to each other in proportion to how many balloons we have, ie how many excess electrons we have. Furthermore, when the water is extremely charged, it will not even leave the thin remnant layer of water that trails behind, as the cohesive internal forces outweigh those by induced to outside neutral surfaces.

Apparently, I saw this video online and I decided to share. What this worker is applying is called bitumen, or what many of us know as bituminous coating. Most people think a wall is a solid, impenetrable block, but in reality, it is more like a sponge. Concrete and blocks have microscopic pores that pull water from the earth through a process we call capillary action. This thick black substance is the shield that stops that water from climbing up into the house. It is not about making the wall look good because this part will be buried under the dirt forever. It is about creating a skin that water cannot breathe through. When do you need to do this? The need for this arises because the soil is a very aggressive environment. Water is not your only enemy.. The ground also contains salts and sulfates that want to eat away at the cement. If this moisture finds its way to the steel bars inside the columns, those bars will start to rust. And when steel rusts, it expands, and that expansion is what cracks the concrete from the inside out. This coating is the only thing standing between your foundation and that kind of slow destruction. Thats is why if you see wet patches at the bottom of your walls inside your house, it usually means someone skipped this step or did it poorly during construction. You can apply this anytime you are building parts of a structure that will stay in contact with the ground. It is common in areas where the water table is high or where the soil stays damp for most of the year. This is a one-shot opportunity. Once you backfill the soil, you can never go back to fix it without a lot of expense and a lot of digging. It is about having the foresight to protect the heart of the building while it is still exposed. Please don’t ignore this if you need to. If you ignore it now to save a bit of money, you will be funding the future decay of your own home. I hope this helps.

From Great Wall Gardens Residents Athi River Great Wall Gardens Management Office Great Wall Gardens Cc: Ederman (Developer) Dear Management Team. Subject: Urgent Meeting Request Regarding Water Issues We hope this message finds you well. As residents of Great Wall Gardens, we are writing to request your presence at an urgent meeting scheduled for Saturday, 18th May 2024, starting at 9 AM. Thismeeting will take place outside the management offices. The primary aim of this gathering is to address the numerous and ongoing issues related to our water supply that have significantly impacted our daily lives and well-being. The following critical points need to be discussed:Water Unavailability: Residents have experienced frequent and prolonged periods without water, severely disrupting our daily activities; 1. Low Water Pressure: When water is available, the pressure is often so low that it becomes unusable for household needs. 2. Misleading Information from Management: We have encountered numerous instances of false or misleading information regarding the water supply situation. 3. High Water Bills: Despite the poor service, residents have been receiving exorbitantly high water bills, which are unjustifiable. 4. Dirty Water: The quality of water provided is frequently substandard, with residents reporting dirty and unclean water. 5. Consistent Same Figure Bills: There is an unusual consistency in the billing amounts, raising concerns about their accuracy and fairness. 6. Estimated/Cooked Water Bills: Many residents believe that the bills are not based on actual consumption but are arbitrarily estimated or manipulated. 7. Smelly Water: The water often has an unpleasant odor, making it unfit for use. Faulty Meters: There are widespread issues with faulty meters, leading to false readings that do not match actual household consumption. 8. Lack of Communication & Water Rationing Schedule: There is a significant lack of communication from management regarding water rationing schedules, leaving residents unprepared for water outages. These issues have caused immense frustration, inconvenience, and distress among the residents. We believe it is essential to address these concerns urgently and collaboratively to find sustainable solutions. We earnestly request your attendance at this meeting to engage in a constructive dialogue and work towards resolving these critical issues. Your presence and cooperation will demonstrate a commitment to transparency and accountability, which are vital for rebuilding trust with the residents. Thank you for your attention to this matter. We look forward to your positive response and meaningful participation on Saturday. Yours sincerely, Concerned Great Wall Gardens Residents.

In the first video, people in Donetsk are seen greeting a water tanker. In the second video, during the rain, people try to collect at least a drop of water because the water pipeline from the Siverskyi Donets was destroyed by the Russians. When Donetsk was not occupied by Russia, the city hosted the European Football Championship, as well as concerts by Rihanna and Beyoncé. Now, there is no more running water in the city. According to the schedule, water only appears in taps once every three days, and even then it doesn’t reach every household, so water has to be delivered by tankers, with long queues forming for it. People use plastic bags as toilets, and this filth spreads everywhere. This is happening not only in Donetsk - water is supplied once every two days in a number of other cities, including Mariupol. This is how Russia 'liberated' Donbas. Why is this happening? In the past three and a half years - since Russia launched its full-scale invasion of Ukraine in February 2022 - reservoirs in Donetsk Oblast have significantly dried up. The water supply system from the Siverskyi Donets River was destroyed. The region’s reservoirs and underground water sources are not enough to meet the needs of the population, in part due to the extensive network of coal mines. When the self-proclaimed “DPR” and “LPR” were created in 2014, Ukraine did not cut off this water channel, as it was still supplying water to Mariupol, which remained under Ukrainian control. But at the start of the Russian invasion in February 2022, the situation changed: the Russian army, during its offensive, destroyed a unique hydraulic structure that had supplied the region’s largest cities with water. The Russian authorities decided to build a new canal - the Don–Donbas canal - which was supposed to begin in the Rostov-on-Don area. It soon became clear that the new water pipeline, first of all, could not provide the region with the necessary amount of water, and second, it was built with numerous violations, with a large portion of the budget embezzled during construction. Crimea is also suffering from a water shortage, and the situation is worsening. One of the reasons why Russia is striving to seize southern Ukraine is that it sees this as a way to "solve the water issue" for the occupied territories.
