Question 1

What are these covers mostly used for?

Accepted Answer

Manhole covers are designed to serve as an effective temporary barrier, preventing debris and other contaminants from entering sewer systems and preventing gases from entering the environment during construction or maintenance. Place the cover over the open manhole or area to be covered. Covers are available as 40” x 40” squares or 36” circles.

Question 2

Are these covers water resistant and reusable?

Accepted Answer

Yes, these covers are made from heavy-duty 18 oz vinyl that is water-resistant and reusable. They help prevent water from entering exposed manholes or drains. Giving the manhole cover a quick spray-off with a hose and a wipe-down is a good way to keep it in optimal condition for reuse.

Question 3

How do I choose between a round and a square cover size?

Accepted Answer

Check the area. Most city and rural manholes are round, so the 36” round cover fits best to prevent leaks. Use the 40” x 40” cover for square manholes and drains. Measure to determine what solution fits you best. Squared edges or round curves at the drain or access point can help narrow the choice. Norseman accommodates custom sizes on request.

Question 4

Do I need any tools or special equipment to install it?

Accepted Answer

You don’t need tools or special equipment for our manhole covers. Our round and square covers have either silica-sand-filled or 5/8” rope perimeters. Silica sand and rope keep the cover's shape, while nylon web handles make it easy to move.

Question 5

What’s the primary use of a temporary manhole cover?

Accepted Answer

A temporary manhole cover is ideal in construction situations when sewer or plumbing work is being performed beneath a street or road surface, and keeping debris, water, or other contaminants out of the workspace is necessary to protect workers below.
