R-Tie and Core Width Options
Perhaps R-WALLs biggest design advantage lies in the innovative design of its R-Tie. The R-Tie length can be easily altered and this simply alters the width of the concrete core achieved, as illustrated below.
159mm 6" R-Tie
159mm or 6 inch Concrete Core
212mm 8" R-Tie
212mm or 8 inch Concrete Core
262mm 10" R-Tie
262mm or 10 inch Concrete Core
313mm 12" R-Tie
313mm or 12 inch Concrete core
The R-Tie has been designed to allow concrete to flow easily through the cavity. The protected design keeps core congestion to a minimum, helping to achieve a complete and uniform fill efficiency. An individual R-Tie has been tested to hold up to 250kg in weight - that's the weight of a small motorbike!
R-WALL does not require the addition of reinforcement as standard. However the R-Tie has specific locators where reinforcement/Re-Bar can be placed and secured to ensure correct covers of concrete are achieved.
Moveable cavity R-Tie's
Perhaps R-Ties biggest advantage however is the versatility it offers within build. The R-Ties can be moved within the cavity to accommodate almost anything. The pictures below demonstrate just some of the reasons why this functionality is so important.
