Concrete - When and Where You Need It

U Cart Concrete Niagara Inc: Ready Mix Concrete in St. Catharines

Since 1976, U Cart Concrete in St. Catharines provides high-quality custom concrete, mixed to your specifications. We can mix from as little as ¼ yard to as much as 1 cubic yard at a time, generally within 10 minutes. We offer a variety of concrete products and mixes, crafted using material from prominent brands. Our Super Strength concrete is designed to withstand the elements, and is available with a mix ratio of up to 40 MPa. 

In the Mix

When we create a custom solution for your project, we can add various elements to the mix to ensure that the concrete retains its strength and durability for years to come. Examples include:

  • Fiber mesh 
  • Sika fiber 
  • Concrete weld chemicals, 
  • BASF air entrainment and Retarder

We can also mix colours into your concrete, or create a texture of raised aggregate pea gravel.

A Simplified Process

Customers have the flexibility of picking up a load of ready mix concrete using one of our specially designed U Cart Concrete trailers. The trailer rental is yours for two hours, allowing ample time to complete your project. Once you’ve finished your project, you are required to wash out the trailer with water and return it to U Cart Concrete in the time frame given.

Every batch is mixed individually to each customer’s specification and preference, allowing them to be tailored for different strengths and mixtures. Air entrainment is added to all mixes, and Propex Fibermesh® and concrete weld can be added by request. Please call for information on colouring requests.

Concrete Delivery

We also provide a concrete delivery system; the delivery charge varies depending on the city. Our trailer and delivery systems can be used in combination loads in order to speed up a project, save costs on travel, and for pure convenience. You tow the trailer and the delivery truck will follow, allowing you to stay on the job site while we return the emptied trailer. Our delivery trucks fit where our competitors will not, allowing you the option of pouring concrete directly into the form.

If you’re able to pick up your concrete by yourself, save on delivery costs by using one of our U Cart To Go trailers. Simply schedule an appointment to pick up your material, and drop by our plant with your vehicle. In order to carry the trailer, your vehicle must be equipped with a trailer hitch and a 2’’ ball. We then hitch the trailer onto your vehicle, load the concrete, and send you on your way.

Once you have the trailer in tow, you have a two-hour window in which you must transport the concrete to your work site, clean the trailer, and return it to our plant. Exceeding this time frame may result in additional costs.

More than Just Concrete

 As a complement to our custom concrete services, we also offer concrete blocks for various uses. Available in various levels of strength and consistency, our concrete blocks are ideal for building walls, curbs or steps.

If you have any questions for us, please call us any time to place an order. We will be glad to assist with free advice, estimates, measurements, and reservations.
