Pools and Spas

What Does "Trenchless" Repair Mean?

Trenchless refers to a repair method that does not require digging. When using our system we don’t have to dig up your garden, cut into concrete decks around the pool causing unsightly patches or structural concrete underneath the pool or spa. Our system is easy to apply, very fast and you don’t even have to drain a single drop of water out of your pool. The repair process is usually accomplished within one day.

The liquids in our system are 100% environmentally safe and made from common additives found mostly in the food industry. Our unique trenchless swimming pool repair system doesn’t effect the inside diameter of the pipes either. There is a reason why your pool contractor installed a 2inch pipe and not a 1 ¾  inch pipe.

How Does It Work?

We developed a unique system that allows us to repair your pool without even draining the water! The damaged pipe will be blocked on the side of the pump, special pipe plugs with hoses will be attached to the outlets in the pool and the pipe system will be flooded with two environmentally friendly liquids. The system forms a natural stone around the pipe as soon those two liquids meet with the soil. The repair is made to the outside of the pipe!

The Advantages:

  • Absolutely NO digging
  • NO concrete work
  • Work done in ONE day
  • No loss to the inside diameter of the pipe
  • No draining of the water

What Can Be Repaired In Pools:

  • Return Lines
  • Suction Lines - Skimmer, Main Drains and Additional Suction Lines
  • Spa and Stair Jets
  • In Floor Cleaning Systems
  • Vacuum Lines
  • Spas
  • Waterfalls
  • Fountains

Material Stability

POOL PIPE GROUT is resistant to substances like chloride that can occur in swimming pool pipe systems. The conglomerate that is formed by our process is similar to sandstone and does not contract after hardening. It does not dissolve, is stable in form and remains permanently environmentally neutral.

Pool Leaks

Here are clues that might indicate a pool leak:

Algae or other persistent water quality problems indicating imbalances in the chemistry that can occur when a leak prevents the water level from staying constant;

Loose tiles or cracks in the pool deck;

Cracks and gaps in the bond beam; or

Water-saturated soil in localized areas around the pool, pool pumps or plumbing.

If you suspect your pool is leaking, there are several reliable ways to check. Try one of these approaches:

Use a grease pencil to mark the water level of the pool at the skimmer. Check the mark 24 hours later. Your pool should lose no more than 1/4 inch per day. Otherwise, a leak is indicated.

The bucket test: Place a bucket filled with pool water on a pool step (weight it with a rock or brick). Mark the water level on both the inside and the outside of the bucket. The starting point levels should be about the same. Check the mark 24 hours later. If there's a greater drop in the line on the outside of the bucket, a leak in the pool is indicated.

When in doubt call a leak detection company to further assist you in determining if your pool has a leak and where.

Determining The Location Of The Leak

If you determine that your pool is losing water, turn off the filtration system and note where the water stops dropping.

If the water stops at the skimmer, the leak is probably in the filtration system. The lines may crack at vulnerable elbows and fittings that are under stress from shifting soils.

If the water stops at the light, the leak is probably there.

If the water drops below the light, then there may be a leak in the drain at the bottom the pool.

If you suspect you have a leak in the filtration system these clues may help you pinpoint the location:

If you see bubbles in the return water when the pool's pump is running, it's likely there's a leak in the suction side of the filtration system.

If the pool is losing more water while running the pump, then water is being lost on the return side of the system.

Swimming Pool Tips

Want to save money, energy and water while properly maintaining your swimming pool? To help you we put together money-saving tips on these important topics: pool covers, leaks, pumps and filter systems.

Pool Covers

Using a pool cover regularly reduces evaporation by 90 to 95 percent.

Without a cover, an average pool of 18 feet x 36 feet loses about 1 inch of water per week in the peak of summer. This can add up to an annual water loss of 7,000 gallons.

One of the most important benefits of using a pool cover can be enhanced safety.

You can cover a pool without being concerned about gaseous exchange, unless you are using chlorine gas. If you are using chlorine gas, you should let it air.

Pumps, Filters and Water Quality


A pump should be able to circulate pool water at least every 24 hours, but every 8 hours is preferred.

Most existing pool pumps are over sized for the size of the pool and plumbing, which reduces filter effectiveness and causes more wear and tear on plumbing.

For the average 1-1/4 inch to 1-1/2 inch plumbing pipes, a pump of only 1/2 horsepower is needed. Many pool owners have bigger pumps, which dramatically increases electrical pumping costs. For example, a 1/2 horsepower pump will cost about $300 per year to run, while a 3/4 horsepower pump will cost $450.


Current cartridge filters are now almost as effective as diatomaceous earth filters, are much easier and safer to maintain, and require very little water for cleaning.

Each time you backwash sand and diatomaceous earth filters you use about 500 gallons of water.

Water Quality

Proper chemical balancing can prevent and cure most water clarity problems.

When is it appropriate to dump your pool water? Not as often as you may think. Pools can often go 10 or more years without draining and refilling. Here are some guidelines:

When the total dissolved solids (tds) get too high.

Water quality problems often can be solved by draining only a portion of the water.

If you have to drain your pool, make sure you take steps to prevent the pool shell from popping out of the ground. Using a hydrostatic valve or drilling holes in the bottom of the pool can prevent this problem.
