5 Key Elements of Successful Single-Sided Construction
Single-sided construction, otherwise known as blindsided construction, makes building in difficult locations possible. These locations usually consist of concrete forming in urban areas where the concrete structure being built butts right up to another surface. This surface forms the blindside of the form, with just one single side of forming holding up the other side. Single-sided applications can also include geographical hurdles, such as rock or soil as the blindside of the concrete forming. There are 5 key elements that that you should think about when tackling a blindsided wall system.
Evaluate the Surface and Use the Right Anchor
The three types of surfaces that form the blindside of single-sided construction consist of concrete, rock, and dirt. Each surface type requires the use of a unique anchoring system. Tying into old concrete can be difficult if it has been weakened by elements and harsh conditions. The same can be said of rock surfaces that easily crumbles, or a sandy soil that gives way when a hole is drilled into it. In situations like these, grout or epoxy-bonded anchors can be used since they don’t exert lateral stress on compromised surfaces. Mechanical anchors are better suited for areas with hard rock surfaces or solid concrete.
Select the Forming System and Material That Will Provide the Most Versatility
A versatile forming system will improve job safety and efficiency. Some streamlined systems are designed to work well with minimal accessories and supports to save on equipment costs and time.
Provide for Waling and Bracing
Providing mounting for waling and bracing is important. Walers are brackets that connect to the form to provide connection for wood or aluminum bracing to prevent Make sure that there is a space for this reinforcement at proper intervals to maintain a straight pour.
Use Ties with the Correct Strength Rating
Ties should always be rated to handle the load that the concrete pour provides, and should be adequately spaced. Otherwise, the risk of losing time due to a collapse rises exponentially. For this reason, it is also important to inspect the formwork one final time before the pour.
Watch Rate of Placement and Don’t Overload
The rate of placement is just as important as making sure that the single-sided formwork and ties are rated to hold the weight. It’s important to monitor the formwork to detect any failure points while the pour is ongoing. Because formwork always presents a risk, make sure to develop an exclusion zone around the formwork to keep personnel safe.
