Installation
MegAtec 340 is supplied in A01 (floor to floor) and A02 (floor to wall) variants, in 25, 38 or 50 mm heights. When specifying, add the required height to the product reference — for example MegAtec 340 : A01-075-050 denotes a 75 mm gap joint 50 mm high. Send us your gap width, movement class and traffic loading and we will confirm the reference and return the CAD detail.
Applications
The MegAtec 340 on our projects
Nine of our written-up projects use the 340.
A clause written to the MegAtec 340 data sheet
Worked for a 100 mm floor joint. Change the gap and the movement for each location on the joint schedule and leave the rest. It names what the joint must do rather than who makes it, so an alternative has to match the performance, not just the description.
Each requirement is explained in how to specify an expansion joint. Writing to a CPWD tender? See the DSR items. See also expansion joints in buildings and the types of expansion joint.
