Segmental Retaining Walls

SEGMENTAL RETAINING WALLS

RETAIN-A-ROCK™ IS A COMPLETE SEGMENTAL RETAINING WALL SYSTEM DESIGNED AROUND A 24 SQUARE FOOT BLOCK. END BLOCKS, TOP CAPS, AND HALF BLOCKS ARE READILY AVAILABLE TO COMPLETE ALMOST ANY DESIGN.

  • Retain-A-Rock™ is a segmental retaining wall system which relies on its mass and interlocking design to provide stability without the use of mechanical tiebacks.*
  • Our precast retaining wall system is designed for any application, commercial, residential, and shoreline protection.
    Significant installation savings, other systems require between 5-12 more blocks to equal one 24 square foot Retain-A-Rock™.
  • True gravity walls, eliminating the use of mechanical tie-backs and geo-grid up to 15 feet in most cases.
  • Unique hollow design provides integrated drainage system and maximizes freight costs (230 lbs/sq. ft.).
  • Blocks are self-aligning, locking each layer into the one below ensuring precise layout.
  • 6000 psi high strength concrete designed to withstand freeze/thaw cycles.

A TRUE GRAVITY RETAINING WALL

Design Concrete’s precast retaining wall blocks provide a true gravity retaining wall system and are quickly becoming a standard in the industry. Retain-A-Rock™ offers many advantages over other retaining wall systems, with a staggering 24 square feet of face per block, our segmental precast retaining walls can be erected much faster than other smaller block systems. While Retain-A-Rock™ was designed for large commercial retaining wall projects it’s advantages can be used by anyone.
Retain-A-Rock™ is installed using equipment which eliminates costly manual labor that is required for most retaining wall systems. Our product has the ability to create 15 foot high retaining walls without the use of geo-grid in most applications. Higher retaining walls can be achieved without mechanical connections, using geo-grid.

Retain-A-Rock™ is a complete segmental retaining wall system designed around a 24 square foot block. Accessories are readily available to complete almost any wall, including end blocks, top caps, and half blocks. The blocks are cast in a high quality mold, formed to maintain accuracy on every piece. The quality of precast versus poured in place concrete ensures the long life of the retaining wall blocks.

Upon installation, the blocks are filled with specified aggregate to create a self-draining wall system and achieving a 100% connection between blocks. All components are produced in our CSA certified facility and are designed to comply with the Ontario Highway Bridge Design Code. With professional engineering assistance available we look forward to working with you on all of your concrete retaining wall projects.

GABION BASKET ALTERNATIVE

Our Retain-A-Rock™ retaining wall system can also be used as a cost effective alternative to gabion baskets. Traditional gabions have been used for many years for commercial, industrial and road projects as a way to create gravity retaining walls. Gabion retaining structures are filled with rock at the project site by hand, which leads to extensive manual labour. Retain-A-Rock’s hollow design provides an effective drainage system without the time consuming manual labour associated with gabion retaining walls.

Design Concrete now offers anti-graffiti treatments for our concrete products which can be applied during the production process.  This eliminates any time period for taggers to vandalize the wall after installation but before the treatment can be applied. Spray paint or other permanent marking products then sit on top of the surface coating allowing for easy removal.

 

Our standard anti-graffiti solution is a semi-permanent, non-toxic product which is safe for the environment.  When graffiti is applied to the wall it sits on top of the surface coating. The graffiti marking is then removed along with the sacrificial coating. The coating is then re-applied to the affected portion of the wall ready to protect against the next graffiti attack.

Standard features include…

  • Non-toxic formulas available that will not harm the environment
  • Coating can be applied during production, eliminating window of opportunity for vandals
  • Coating will not affect the original colour of the surface
  • Different packages available for removal and maintenance
  • Variety of options available to suit any specific needs
  • Other anti-graffiti options are available to meet different project requirements.

FREQUENTLY ASKED QUESTIONS

What are the standard precast retaining wall block sizes?

Design Concrete’s Retain-A-Rock system is designed around a 24 square foot (face) block; the dimensions are 3’ high x 8’ long and 44” deep. Also available are half blocks (12 sq. ft.) end blocks, and top caps to complete almost any design.

Can I have the product customized?

Customizations can be made to incorporate railings and structures on any Design Concrete retaining wall or product; half blocks and top caps can be used to achieve a wide variety of heights and any other requirements you may have.

Where is the product manufactured?

All of Design Concrete’s products including precast retaining wall blocks, are manufactured in one of our CSA certified facilities and are held to the highest quality standards. Our production plants are located in Seaforth – Ontario.

Why are precast concrete products better?

Precast products offer many advantages over pour in place concrete. Precast simply means the concrete product was manufactured in a plant before hand, as opposed to being cast on-site.

“Because precast concrete products typically are produced in a controlled environment, they exhibit high quality and uniformity. Variables affecting quality typically found on a job site –temperature, humidity, material quality, craftsmanship – are nearly eliminated in a plant environment.”
(NPCA – www.precast.org)

Does Design Concrete install the product, or do I?

Design Concrete can provide products on a supply only basis or supply and installation. If you require installation services please contact our office so we can find a pre-qualified contractor who has worked with us in the past and knows Retain-A-Rock best.

How much manpower and equipment is required for installation?

The majority of the installation process is accomplished with an excavator which eliminates extensive manual labor that is normally associated with average size retaining wall blocks. With 24 square feet of retaining wall installed with one block, the advantages don’t take long to stack up; along with your wall.

How long does it take to install a modular precast retaining wall?

Installation times are always dependent on the size and location of the project. For most projects a general guide of 1200 square feet of precast retaining wall per day can be installed.

What area does Design Concrete service?

Design Concrete’s main service area encompasses Ontario, Quebec, Michigan and surrounding areas; however due to the specific nature and quality of our products, we have shipped as far away as Montana and California.

What is the smallest order I can place?

Standard size products are always kept in stock which allows Design Concrete to supply almost any size of project; large or small. Custom products are made on a “by order” basis and can be ordered in almost any quantity.

How much does it cost?

Costs for production can change depending on variables which fluctuate on a regular basis (i.e. commodity prices). For the most up to date pricing information please contact the Design Concrete office at 1-877-253-4577 or send email to info@designconcrete.ca

Do I have to make shipping arrangements?

Although generally Design Concrete handles the shipping logistics for their customers, you may make delivery arrangements of your own, if you have the means to do so.

How can I get a quote?

To provide an accurate quote we will require certain information regarding your project. Please contact one of Design Concrete’s sales staff for a Retain-A-Rock quote at 1-877-253-4577.
