Repair and restroration of swimming pool


5 reasons why swimming pool leaks

We will introduce 5 major causes of swimming pool leaks. If it is found that the water in the pool is missing more than 2-3 centimeters per day of water level within a day or 10 centimeters per water level reduction within a week. We found that your pool may have a leaking problem. We would like to classify leakage into 5 topics as follows:

  • Device problem or mechanical issue

  • The problem of leakage caused by the structure of the pool

  • Problem from water system 

  • Leakage problem from broken pipes

  • There is a problem with the pipe connection point.

Problems with leakage from the device

This is a problem caused by the equipment used in swimming pools such as automatic water filling device or the vortex system used in the swimming pool or equipment that helps to remove sediment from the pool, the water pump system, which, if any such equipment is damaged, will inevitably lead to leakage in the pool._cc781905-5cde-3194-bb3b -136bad5cf58d_

The problem of leakage from the swimming pool structure

It is well known that reinforced concrete structures are not 100% waterproof and structural problems such as cracks, cracks or joints in concrete that are not installed with equipment or waterproofing materials will cause leakage. Yes, and repairs are difficult.

The problem of leakage under the pipe system under the pool floor.

The piping system under the pool floor involves a complex piping system. After prolonged use, corrosion occurs. As a result, the pipe breaks. cracks or leaks under the pool floor system A sonar leak detective device must be used for further investigation and correction.

Leaking pipe and elbow problem

It can be solved by extracting and replacing broken pipes.



Problems arising from the construction of the swimming pool

Problems or defects encountered in swimming pool construction, both during construction and after use are countless as swimming pools involve a wide variety of construction materials and also require maintenance costs. Care throughout the lifespan In this article, we will focus only on the construction of structures and finishing materials, but not on the parts of complex systems and equipment. By requesting to separate parts of the system in another article 

Before going on to discuss the problems that must be faced in the construction of the swimming pool. Let's first understand the structural swimming pool design. We found that the concrete structure is subjected to loads in several ways: lateral soil pressure. Water pressure acting on the inner pool The suction force caused by sucking water out of the pool creates negative pressure, or the weight of the water acting on both vertical and horizontal structures. 


The goal of the pool design is Strong structure to withstand all conditions of use There is no leakage or outflow of water through the structure or even equipment. The structure must be resistant to rust and have no long-term deterioration issues. 


How to prevent water from leaking joints of swimming pool walls and floors

The seam in the swimming pool has two important parts: .

  1. A joint that occurs during concreting or a construction joint is a joint caused by a stoppage due to concreting. According to the amount of prepared concrete will be poured. Therefore, there will be a joint between each pouring. We recommend using rubber waterproofing or pvc waterstop to seal the joints before concrete is poured. This rubber seal will help prevent water pressure from entering the area most vulnerable to leakage is this area. 

  2. Spaced joints for installation of equipment, water pipes, sewage pipes, sewers, drainage pipes, electrical pipes or various fountain equipment. This is usually a pipe that goes through a wall or concrete floor. For pipes, we will use a variety of waterproofing materials, such as swollen rubber, wrapped around the pipe, after that, when the pipe has penetrated, then use a waterproofing tape cloth over it again. After that, sealant or pu grout can be used to cover the surroundings again. How do leaks occur in these areas because they are the connections between concrete and equipment or pipes? Therefore, have the pool contractor identify these points, when there is a leak, it will be difficult to find the leaking point and difficult to repair the water leak. It also costs a lot to repair.


swimming pool waterproofing

After the walls and concrete floors have been cast and the joints have been installed waterstop, it is time to make the waterproofing system for the swimming pool. (Waterproofing for swimming pool) around the wall and floor Allow the concrete to dry for at least 14 days before applying the waterproofing system. Swimming pool waterproofing requires the use of good and suitable waterproofing materials as the pool is constantly immersed and repairs or repairs are costly. Therefore, the selection of waterproofing materials for swimming pools is a special consideration. Therefore, we recommend to use 2 layers of waterproofing material to prevent double leakage as follows:

  1. Membrane waterproofing is a woven roll that can be attached to the concrete surface by using a tile adhesive mortar. This waterproofing fabric Able to withstand the flexibility, twisting or shrinkage of the pool structure when the load is applied, and does not allow water or steam to escape. waterproof fabric Installation to overlap 5-10 cm. This type of waterproofing system cannot be purchased in the market or building material stores. often have to be imported from abroad And this type of waterproofing is much better than a paint or coating system because it is durable and waterproof, of course, every square meter that is laid, plus it has a longer service life than other types.

  2. Waterproofing type (coating type waterproofing) is a cement-based, two-component waterproofing. The installation is applied to the surface of 2 or 3 coats according to the design and depth of the pool wall. This type of waterproofing depends on the solution mixing and the thickness of each coat. 

Once the waterproofing system has been installed in the swimming pool Curing the material according to the specified time and method. Wait for at least 5 days to set before tiling. The curing time should be checked with the waterproofing manufacturer. Immediate tiling may result in negative consequences, such as loose tiles. surface subsidence etc. 

Checking for leaks before tiling

Once the waterproofing system has been installed If you want to check for water leaks We should do this before tiling. Swimming pool leak test We will use the water to fill up and run the pool system to have real pressure according to the actual usage. The most popular is to keep the water in and run the system for at least 24 hours in order to check the pool for leaks. If the trapped water has decreased significantly. should be corrected By focusing on cracks, joints, welds, equipment, pipes, and fix the leakage. or if it is a leaking structure, for example Any cracks in the pool structure after full water filling can be repaired by repairing the epoxy injction or polyurethne injection structure. The reduced water should not exceed the normal evaporation of the water. If there is a significant reduction then the leak should be found and repaired. 

In the event that, after checking, there is no degradation that is too high can be laying tiles

Fixing leaks in swimming pools

Where water seeps through cracks, fissures, crevices and swimming pools are not buried in the soil or the pool structure rises above the soil. where we can see the leak clear water seepage There are water stains around the pool. We can repair this leak by compressing a water-based release agent or a polyurethane foam injection or epoxy injection water-stopping resin. edit like this You don't have to go into the pool to do anything. but repair outside the swimming pool Fixing the pool water leak this way. Need to see the water stains seeping out. in order to compress the liquid along the cracks seen Therefore, there are many pools, most of which are buried underground and cannot be explored outside. This type of repair requires dismantling the tiles inside the pool and then making a full waterproofing system. pour water again which is very costly 

After each method of repairing water leaks Water can also deflect the seepage to see other places with cracks or other leaks. therefore need to be repaired until the structure has no cracks. Once the repair is complete, it can be used normally. and check every 3-5 years 

Swimming pool tiling and grout

swimming pool tiling Two important materials involved in waterproofing are Tile adhesive mortar and tile grout The principle is simple. Choose the type of tile adhesive mortar used for swimming pools. Which will be tougher and more durable than general crab glue Both have more opacity than water. Therefore, choose to buy materials according to the specification. The same goes for the sealant. Choose a tile grout that is suitable for swimming pool applications. which is more durable than conventional. 

The tiling is to be covered with all adhesive mortar. The level and plummet must be decorated with cement mortar. Do not use cement-sand or steamed buns. Because it will cause it to fall off easily. Plus, the level may be distorted according to the skill of the tiler. In case the surface to be laid is distorted both vertically and level, check again.
