How Do Concrete Contractors Construct a Concrete Chimney?

A concrete chimney is a great choice for a new or remodeled home. However, the concrete will shrink and crack during the construction process, causing the crown to deteriorate. Concrete Companies in Queens NY ensure that the crown slopes away from the flue. In addition, they see to it that the cement is cured properly to prevent water from sitting on it. If you are not comfortable with the idea of a concrete chimney, you can consider a metal or asphaltic-rubberized membrane.


In forming a concrete chimney, the first step is to make sure the chimney has the proper size. Ideally, the height should be at least eight feet. A specialized form is needed for large-diameter chimneys and accelerated schedules. The slipform construction method involves continuous pouring of concrete into one single form. The shell taper is controlled using an integrated hydraulic jacking system. Lasers continuously monitor the alignment of the concrete and formwork.

The form is an essential part of the chimney’s construction since it will determine the final appearance. Wood forms are generally smaller and cannot be directly attached to the edge of the chimney. Instead, they are supported by roof supports. Nails are set in the inner sides of the wood forms and the top course of masonry. After installing the forms, it’s time to add the flue liner. The finished product should look like a professional installation.

The concrete chimney cap is essential to prevent water from entering the home through the chimney. This allows water to corrode the surrounding bricks and can lead to further damages. Over time, the bricks in your brick fireplace may spall, allowing water molecules to erode them. If the chimney is not properly capped, you will find brick pieces on the roof or gutters. If the chimney cap is made of clay, the cement may not cure completely and it could lead to a hazardous situation for your home.

In addition to the chimney’s exterior, the concrete chimney’s interior is just as important. It protects your home from harmful gases from inside your home. It’s also a great choice for tall chimneys. Depending on your needs and your budget, a slipform is a great option for an accelerated schedule. However, this method of construction is very labor-intensive and requires experienced workers. In the end, it will last for many years and look beautiful.

During freezing weather, water can seep into the concrete chimney cap, and it can even cause the masonry to collapse. If you are building a chimney with a wooden cap, the wood form has no supports, so the roof supports must be used to support the form. If you’re using a metal chimney, you must also use a metal or a wooden form.
