Concrete Forms Tips

Single Sided Problem Solving

Every day, cities are expanding and rebuilding in order to accommodate growing populations. As a result, there has been a spike in the number of specialized construction projects, and specialized construction problems. The most common issue arising during expansion is the challenge of adding concrete to an existing material or surface for construction. What makes this so challenging is figuring out how to secure and hold the formwork in place.

Secure SolutionsSingle Sided Problem Solving



The solution is securing the existing surface using properly functioning ties. Surfaces like rock are known to be very stables surfaces, while others can cause difficulties. Take worn concrete for example. Having concrete that has been exposed to the elements and other harsh conditions over many years may have weakened the material, making the tying an issue.

Single Sided Forms

Another option is to use Single sided wall forms. These forms are perfect for use in underground subways, basements, or any place where new concrete must be placed against preexisting concrete. Usually this process is done without the usual form ties to help prevent adjoining concrete stresses. However, one-sided wall forming without ties can often lead to bulges or blow-outs. To solve this, contractors must use either bracing or special formwork components.

Blind Sided Forms

When forming against a preexisting foundation wall, if space allows, there is a possibility that two-sided forms can be used. The blind-side, or the back-side, between the old and new wall can be formed with instruments similar to those used for one-sided forming. However, blind-side wall forming can be pretty complex since there are several methods that have been proven to work.

One of the most crucial parts of a successful blind-sided forming project is getting the ties into place and anchored. Some contractors develop their own forms using metal staying-place forms with ties welded to them or ties slipped through holes then hooked on rods behind the metal forms.

Forming America has the ultimate solution for the blind sided anchoring issue: the Seawolf Blindsided Wall Forming System. This system takes a unique approach to one sided wall forming that eliminates the need for “weld-on” ties, anchors, or “A-frame” supports. As a result, using the Seawolf Blindsided Wall Forming system can dramatically reduce labor and equipment costs.

If you choose to go with traditional single sided forms, there are several beneficial methods, types of materials, and forms of equipment available to help make one sided forming more of a routine matter. However, there are still things that need to be watched for. Professionals advise using ties of adequate strength and following the builder’s recommendations. Also, watch the rate of placement, which avoids overloading of the ties and forms. The existing side will not have the stability and strength of the formed side.
