Flood Grouting Systems:
Pool & Low Pressure Plumbing
What Is Flood Grouting?
Flood Grouting is a two part liquid system that repairs leaking pipes. The ingredients are environmentally friendly. The repair is made to the outside of the pipe and therefor does not reduce the flow of water through the pipe after the repair is completed. The patch that is formed on the outside of the pipe is similar to sandstone and does not shrink or expand after hardening. The repair process is performed with two people, takes less than a day to perform and cures within a couple of days.
For Pool Line Repairsyou will be able to make use of the line 72 hours after the repair.

What Is “Trenchless Repair”?
In order to Flood Grout the pipe that is leaking you simply pour the products into the pipe at the highest point in the pipe and pump it out from the lowest point. You do not need to dig the pipe up in order to do the repair…you work with the two ends of the pipe that are exposed to the surface.
For Pool Line Repairs this means that your expensive pool deck does not get damaged in anyway…no unsightly patches!
How Does It Work?
Once you have determined that a particular line is leaking and it has been isolated, you need to pump out the existing fluid in the line.
Once this has been completed you should flush the line with water to clean out and loose debris, by measuring the volume of water required to fill the line you will also be able to get a better idea of the extent of the damage and the quantity of product required to carry out the repair.
After the line is flushed and water removed the first product (PG1) is poured into the line from the highest point…by using a valve at the lowest point you are able to bleed out any air that might get trapped in the line. You continue to fill the line as the product oozes into the ground through the leak in the pipe.
When the product level remains constant – this process can take up to 45 minutes – you then pump out the product that is in the line from the lowest point and salvage this material for later use. At this time you then flush the line with water and you pour in our second product (PG2) and repeat the process.
In some cases you repeat the process a third time using our first product (PG1) to ensure that the repair is totally effective.
The first step in answering the question “Is Your Pool Leaking” can be done by doing a very simple test, it is called the Bucket Test.
The bucket test is used to determine whether or not you are losing water due to a leak or simply evaporation.
- Take a mop bucket or a 5 gal pail and fill it approximately 2/3rds with pool water.
- Place the bucket on the second step in your pool so that the bucket is partially submerged in the pool. By doing this both bodies of water are at the same temperature and they are subject to the same rate of evaporation.
- Now Carefully mark the water level on the outside of the bucket using a felt tipped marker or a piece of tape, do the same for the water level on the inside of the bucket.
- Allow at least 24 hours and check the water level’s relative to the marks you made previously.
- If the water level is still at the mark both inside and out or the level has dropped the same distance then you do not have a leak, but
if the water level has dropped more on the outside of the bucket than the inside you have a pool leak!
Watch the bucket test demonstration:
Once you have determined the pool is losing water, Leak Detection is required to isolate the source(s) of the leak. Leak detection companies have sophisticated equipment to locate where a leak is in a plumbing line or in vinyl liners. Pressure tests will also need to be performed on the pool lines.
Call a qualified Leak Detection company that provides a thorough inspection and testing of plumbing lines, skimmers, pool equipment, pool liners or shells.
Leaks that loose pressure quickly and where only a low pressure reading can be obtained, it is recommended that a camera inspection be performed in order to better understand the extent of the damage. In a lot of these cases our “Block & Seal” product should be used prior to flooding the lines with PG1 and PG2.
