IMPORTANT NOTICE:

Please ensure that you build up the wall as you place the blocks. Do not lay the full first row, then the second, etc.
Build up as you build out, otherwise you run the risk of the blocks not locking properly.

Gravity Block Walls

A gravity wall is a wall designed on mass and weight of the materials in the wall. Gravity walls require – NO TIE BACKS – and are usually applicable in a “cut slope” situation.

Gravity walls save considerable cost on excavation and structural backfill.

Mechanically Stabilized Earth

MSE (Mechanically Stabilized Earth) Walls, or tieback walls, are best used in “fill” slope situations. They are built with a combination of blocks and GEOGRID tiebacks.

TerraBlock units are an excellent replacement for small block walls as an installer is able to place 12 square feet of face at a time. Typical installation estimates are 10-15 blocks per hour.

MSE walls incorporate GEOGRID products to reinforce the wall. These grids allow walls to be built vertically, with a minimum amount of block.

Testimonials

“In 2010, after researching the market for vendors who could supply us solid poured concrete blocks, we came across DNM Systems. David, from DNM, was quick to respond to our initial message and scheduled a site visit to determine the best block to meet our requirements. We agreed that the “Terra Block” would best suit our needs to create physical partitions and barriers between work areas within our facility. We were quoted competitive rates, ordered blocks and contracted DNM for delivery and set up. All the staff at DNM are very pleasant and professional to deal with. Our order was ready within a week and delivered promptly. DNM sent 2 very skilled personnel to set up the blocks at our facility and the setup was completed as scheduled. David once again visited the facility to ensure the work was completed on time and as planned. Since then, DNM have become a preferred vendor and we have purchased nearly multiple blocks and will continue to use their services."

"I have used your blocks on many occasions for retaining walls, yard improvements and to address safety concerns. Delivery was second to none based on the size and volumes never delaying any projects and always just in time. Your onsite consultations were most helpful in planning and determining the best approach. Prices were very competitive as all our work is tendered and our contractors are some of the largest. Please find attached some pictures of our success (below)."

"Awesome! I'll definitely be calling you guys soon for more blocks! Thanks for everything :)"

"Your blocks have exceeded my expectations and you were great to work with. I have referred you to another pool company. Thanks for your help.

We have been extremely impressed with DNM Systems. From calling the company, talking to the administrative staff, ordering blocks, delivery of blocks, the company is excellent to work with. The blocks are very easy to work with, they go up without problems and are versatile for all types of situations.

We have been using the TerraBlocks and StoneTerra Blocks for a couple of years now and have had no issues. We have done a number of projects with DNM Systems, including: The St. Lawrence SeawayRegional Road 81, Freeman Herbs The Optimist Park in Niagara Falls... and many more.
