New Product - MoClip - Concrete Spacers











Principal corrosion and concrete deterioration protection is in the concrete cover over the reinforcement. Therefor material integrity of the concrete cover must be maintained.

iwi Group is a reseller of concrete spacers with wet-cast, high-performance concrete in various shapes to maintain the material integrity of the concrete cover. Placing rebar is quick, easy and accurate with the various fixing methods on the spacers.


With IWI’s concrete spacers, you can be confident that the reinforcement will be well-protected from corrosion, because:With IWI’s concrete spacers, you can be confident that the reinforcement will be well-protected from corrosion, because: Cementitious spacers encourage bonding to the surrounding concrete.Non-cementitious and non-bonding bar supports, even if rust-free, are susceptible to ingress of chlorides where they interface with the surrounding concrete. They are shaped for complete embedment and minimal visual effect on finished surfaces. High structural strength and stiffness support heavy construction loads and ensure proper positioning. Fewer supports may be needed compared with weaker and softer supports. MoClip or embedded tie wires ensure secure and proper positioning. Low absorption and permeability of air and chlorides. Low diffusion coefficients reduce diffusion of chloride ions through the concrete to the rebar. Longer resistance to chemical attacks than substitutes. High electric resistivity reduces the rate of corrosion. Thermal expansion compatibility with the surrounding concrete of the structure. Non-cementitious and non-bonding spacers with higher thermal expansion / contraction can cause separation with a slight gap that provides an ingress path for chlorides where the spacers interface with the concrete. Concrete spacers can be supplied with various types of concrete and colored concrete on request. Stock products are made with a 8000 PSI Concrete. 
Concrete spacers and bar supports are made of the same material as the poured concrete, so thermal expansion and contraction are equal. And because they are the same material, the concrete and spacers will bond. No gaps!
