Your concrete isn’t just exposed to general wear and tear like a plant floor or warehouse. Your concrete takes a beating from steam, traffic, metal totes and the chemicals you’re processing. You need repair materials that can take it.
Here a few things to consider when planning your next repair project.
What is the predominant chemical or mix of chemicals that this area will have to stand up to? Your material will have to withstand exposure to these chemicals for a specified time.
Is this area a secondary containment, loading area, storage, processing floor or something else? This will add the effects of temperature, traffic and abrasion to your list of things to consider.
If your area is outside,
We all know that the key to the long term success of your joint sealant is it’s ability to stay bonded to the concrete sidewalls of the joint. But how do you make sure you have the best chance at superior bond in an existing joint. In one word, Prep. Preparation of the joint walls is critical and poor prep is a sure path to failure of the sealant.
Prep of your joints has to be done. And, the easier you make it, the better chance you have at success. There are many unique and high speed saws that are the latest and greatest for this job. But, you don’t have to break the bank to get it done. Chances are, you already have what you’ll need to clean and prep your joints. If you have a grinder, diamond blade, shroud and a vacuum, you have what you need.

Sealing joints in your concrete structures is key to prolonging the life of a concrete structures. Joints in slabs are critical for relieving stress to prevent cracking but they are also the weak point when it comes to traffic. Joints in containment structures are the main route liquids take to get to the ground. Not sealing these joints could lead to reportable leaks or even undermining of the structure if not addressed immediately.
Given that these joints are outside, there are a few things you need to know before you choose a sealant so you can be sure it will last.
They are very different when it comes to the range of movement they will see especially if they are exposed to direct sunlight. Control joints relieve stress in
Re-coating a secondary containment area seems to be pretty easy. I mean, it’s just paint right? Well, it may brush or roll on like paint, but chemical resistant coatings are much more. Before you jump into self-performing a coating like this, you need to consider that you might need a contractor. Here’s some things to think about.
If this going to be a simple re-application of primer and topcoat you should consider doing it yourself. Of course, there will be some prep required. But it should be easily done with the tools you have with some direction.
If the system is new and will require reinforcement at joints and transitions, you might want to get a professional to look at it.
You could probably self-perform if a grout type system is to be used if you have
The best way to deal with grout shoulders is to make sure you minimize the chances of cracking before you start. There are 5 things you should consider before you proceed with the placement of your grout.
Make sure you choose a design that is less prone to cracking. Minimize the size of the shoulders while still making it easy from a constructability standpoint. Think about how the grout will have to be placed and design access in your base plate or frame to make application and air evacuation easy.
Choose a product that will flow and fill your entire space between your base plate and the foundation. Visualize the flow and how it will move air from around the back-side of obstacles like shims and anchor bolts.

Choosing the right grout can be a challenge. That’s why we’ve put together this guide to help you make the right decision based on your project, application, and needs. Refer to the table below to determine which grout is right for you.

Voids between baseplate and grout may be discovered after grouting. These voids may be the result of obstructions, trapped air, or varying grout levels during placement.
There are basic steps to addressing these voids that are meant to ensure maximum contact between base and grout so unused forces are properly transferred to the foundation.
The most common method is sounding. Tap the plate and listen for hollow
Concrete is widely available, customizable to each application and affordable. These traits make it ideal for equipment foundations. It is also the most widely used method for adding mass to a critical piece of equipment or process skid. But, for all its positive traits, there are a few characteristics it’s lacking that would make it better. The truth is there are alternatives to concrete with most of the traits already discussed and other very desirable ones.
Below are five unique benefits to fast-setting concrete:
There are products and additives that can produce a concrete or concrete-like material that can attain an initial set much faster than convention mixes. Some as fast as just minutes. This is to allow for other work on the foundation to begin much faster.
