The Lesa Systems Ltd chart for type, size and spacing of dowels in floor slab joints is based on the best technical information available.

During 2002, the Queensland University of Technology carried out load transfer capacity tests on a range of shear dowel types.

The tests indicated that dowels in sleeves with "thick" plastic walls have a dramatically reduced load transfer capacity.

NOTES ON DOWEL TYPES
* These dowels do not allow lateral movement. This may contribute to slab cracking.
(1) Formwork penetration is required with these dowels.

Thicker slabs?

For information on slabs thicker than 200 mm please contact us or make an enquiry.

Notes on dowel types:

*These dowels do not allow lateral movement. This may contribute to slab cracking.

(1) Load Plate baskets are fully pre-assembled in cage form. (Load Plates are ex 50 x 10 mm steel bar.)

(2) Cost covers dowels and support components only - site assembly required.
(These dowels can be supplied pre-assembled ex factory. Assembled prices generally exceed load plate basket prices.)
