What happens when a joint in a precast manhole begins to leak? The answer is it may as well be leaking money.

About $22k could be lost yearly because of any ONE manhole leak at the rate of 10 gallons per minute. In the U.S, there are approximately 20 million manholes, and many of them have OVER 10 gallons of infiltration a minute. You can imagine the potential loss.

Generally, manholes leak because of either movement and settlement after installation or just plain bad installation. A leak can happen at any time. Thankfully, Alchemy-Spetec offers a quick and effective solution to this problem.

You can seal precast manhole joints using Spetec PUR GT380. It is a hydrophilic polyurethane material that cures to form a gel or a foam. Because it's a single-component material, you can install it easily without the need for mixing. It can easily penetrate joints before it eventually cures into place, thanks to its low viscosity.

Installation is simple.  There are only four steps:

1. Drill holes. Typically, four per barrel joint.
2. Flush the holes.
3. Install your injection port.
4. Inject the resin.

With Spetec PUR GT380, you can have confidence in your work because this is a durable, long term sealing solution that holds up against the harsh sewer environment.  And your clients will be delighted to stop losing money from leaking manhole joints.
