Permalink   
 


Water tank waterproofing is serious work and it should be applied when the event asks for it. But if we talk about various types of water tank, the method for Water Tank Waterproofing in Karachi is different for the different water tank. In practice, there is this change of method, techniques as well as product in some form. But the object never changes whenever some hire a waterproofing company, he’s looking to repair home and areas where damage might exist. There is also an important concept during the fixing of the water tank, that the damage can only be fixed if there is low to moderate damage over the walls and base of the structure, cause if the damage exceeds from an allocated threshold, the waterproofing product won’t bear much fruit. Below are some of the technicalities involve during the waterproofing services for the water tank.

Stores more than just water

In short, there are usually two types of water tank usually found on people homes, overhead and underground water tank. The overhead water tank is located at the top of the home, usually found on large residential apartments which are made from the concrete structure. Then there comes underground water tank, and just like the name suggests, the underground water tank usually stores the water as a staging area which comes either from state-owned water facility or either from sub-level extraction, usually from well. Any case, the water tank stores water, but since we know that in today’s garbage infested water sources around Pakistan, the water also throws away some garbage in the form of plastic or unwanted clutter that clogs up pipes, and ruins the water tank structure to greater intensity.

Size of the water tank

Since we are talking about the differences that might exist between underground and overhead water tank in Pakistan, let’s start with the size of both the water tanks. Comparatively, the size of the underground water tank is way larger than the overhead tank. The main reason usually is to have additional storage capacity if in any case the water transfer is delayed from state-based water pumps or wells, unlike the overhead water tank, the water is already on the transfer stage to respective homes, or if we are referring to a single homeowner, the overhead water tank size become smaller. In short, the greater the size of the overhead water tank, the more damage it will show, but for underground, the damage from water tank could be largely ignored since its way down the underground and doesn’t affect anyone if there is leakage present.

Possibility of two-way waterproofing

As we talked about the difference is waterproofing method, here is the biggest one when compared to the underground and overhead water tank in Pakistan. The underground main affected areas are usually its walls, but since they are also hidden way underground, the effect is minimized and less amount of waterproofing chemical is being used to fix it. As for the overhead water tank, there is more damage response, and chemical application is preferred to undergo interior and exterior walls. This two-way waterproofing is valid for overhead water tank and in some cases a must-have method based on the damage of the water tank.

Filling joints and cracks

The major damages which are usually found over the water tank around the homes are cracks and openings due to decaying concrete walls. These cracks then even make things worse if left unattended. The only option viable in terms of cost and effectiveness is through waterproofing chemical application. When we talk about overhead and underground water tank, the main difference is the amount of product being used over its repairing works. That means, underground cracks are usually more hidden as compared to overhead water tank, but in anyways, whenever a waterproofing product is applied over any of the water tanks, the complete area is covered to ensure not only the damaged area is fixed but also the area where damage could arise is also kept in check.

Limitation of products

There are various types of product to be used for waterproofing purposes. The water tank in general only uses bitumen based waterproofing since the effectiveness is more robust than another form of products available in the market. So there are even the products of various quality, like bitumen membrane and modified bitumen. This is an important concept to understand whenever waterproofing is applied, the product never applies over the dual type of product. So liquid-based waterproofing is the limit when we talk about overhead and underground water tank waterproofing in Pakistan.

Water tank waterproofing is serious business

A waterproofing company is necessary to carry out this process if we want to have a flawless chemical application which bears fruits. Cause not only we are dealing with a water tank which contains water 24/7, but the chemical nature must also be handled with great care. Since the water that comes out from water tank can be consumed for domestic purposes, the chemical used to ensure waterproofing solution is followed according to the requirement of the customers, the product doesn’t come in the way for having a good waterproofing for a water tank in Pakistan.
