D&N CONNECTIONS LLC We are committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade, combined with ability, is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business. Our Professional Excavation Services: Site preparation and demolition Grading and leveling of land Trenching and underground utility installation Drainage work and site stabilization Land clearing and tree removal Road and driveway excavation Pond and swimming pool excavation Rock and boulder removal Backfilling and compaction Snow removal and de-icing Emergency excavation services

"To say that our experience with D&N was a disaster is an understatement. Last July, we hired D&N to grade our yard, install french drains, and install a retaining wall and fence. When we met with D&N, we were told that this would be a quick job and should only take a few weeks. We then found out that they would be subcontracting our retaining wall. We were pleased, as our meeting was very professional. That's where it ended. Not only was it impossible to coordinate with their team, we were constantly told that they would be out to work and then wouldn't show up. A few months in, we find out that this is a side gig for they're team and they all have full time jobs. Fastforward to 8 months later, the job was "finished." During spring, we notice that the french drains are not working properly. When we reached out to D&N, we were told that they had nothing to do with it. Absolutely unprofessional. We've spent weeks fixing issues that should have been taken care of. Do not hire!"

Retaining Wall Installers questions, answered by experts

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

Poured concrete is likely the cheapest way to build a retaining wall, as this material costs anywhere from $6 to $8 per square foot. The next best budget-friendly option is to use landscaping timbers. These timbers are great for DIY projects, as they don’t require tools to successfully build a retaining wall. Landscape timber costs around $10 to $14 per square foot. Depending on your chosen garden style, you can also go with natural stones or concrete blocks. Natural stones can be expensive if you buy them, but they’re a lot less costly if you can source them from your property. 

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.

Generally, a railroad tie retaining wall consisting of a single line of ties should be between 3 and 4 feet tall—and the height often tops out at around 6 feet. You can go taller, but you may need additional footings and reinforcements, including a second layer of railroad ties to support the added weight of the soil it’s holding back.
