Our Resources Common Myths About Repairing Trenches That Stay Wet

Concrete & Floor Repair

Maintaining your trench drain in your facility is a necessity. Damaged trench drains could lead to unpleasant odors and allow bacteria to grow. With all the USDA regulations, cleaning, flooding, or rinsing your trench is a daily routine. This means there is not a lot of time for this area to be dry for repair. Fast application, rapid installation, and quick curing are three things you are going to want to reduce time out of service for your trench and to ensure a complete repair. Doing it yourself means you can make the repairs on your own time and stay on budget without having to hire a contractor. Luckily, there are materials that you can easily apply while the trench is still wet.

Here are a few myths about the materials commonly used to repair trenches:

Myth 1: “Materials can’t bond if the concrete is wet.”

Traditionally, most materials used to repair trenches require the trench to be dry. This means that the area of the drain has to be out of service for some time to ensure the material used to patch the trench can bond. There are now products that can be applied to wet surfaces and even under water that will achieve a tenacious bond.

Myth 2: “Trench repair is a multi-step process that takes a lot of time.”

These products have fillers in them and lend themselves to application as a trowelable lining. As long as the trench hasn’t been compromised (holes through the wall) it can be as easy as smearing the lining on the floor and then up the walls to form an impervious liner.

Why it’s important:

Being able to repair your trench while it’s still wet can be the answer to an on-going problem that seemed to not have a good answer short of tearing out the floor. Also, doing the repair on your own time and not having to hire a contractor reduces your overall budget. This product is innovative and pretty easy to apply. Think of the other fires you could put out with the time that you now have since the trench is back in service.
