Square Dowel

Square Dowel

An engineered load transfer system for horizontal

movement in concrete slabs

The size and rectangular-shape of the Square Dowel

provides concrete joint stability, load transfer and

smooth slab-to-slab transition, without restraining

floor movement.

The plastic sleeve is nailed to lumber edge forms

before concrete placement and the steel plate

slides into the sleeve after forms are removed in

preparation for the adjoining slab.

The Square Dowel simplifies dowel installation,

eliminates slab edge drilling and reduces labor costs

for all types of ground level concrete slabs, including

floors, flatwork and pavement.

The plastic sleeve allows movement and the steel

plate provides maximum bearing, bending and

punching resistance, without the risk of slab interlock

common with other methods.

Rigid, high-density plastic sleeve quickly attaches to

edge forms and minimizes related labor costs.

A properly installed Square Dowel is recommended

for joints up to 0.20” wide and is suitable for all types

of ground level concrete slabs, such as jointed floors,

flatwork and pavement.

A Square Dowel installation conforms to ACI 302.1R

Guide for Concrete Floor and Slab Construction and

ACI 360 Design of Slabs-on-Ground.

03/261. Square Dowel Installation

Mark a horizontal line on formwork for the half

slab thickness. Mark a vertical line for the center-

to-center spacing of the dowel sleeve. Fasten

all dowel sleeves securely at each marked

location. Position and tie any remaining slab

reinforcement.

2. Place concrete normally, completely surrounding

each dowel sleeve location. All dowel sleeves

require adequate vibrator compaction to eliminate

any air entrapment under the sleeve. Do not

strike/damage dowel sleeves with the vibrator.

3. When concrete reaches sufficient strength,

adjoining slab base can be levelled and

compacted. Insert the steel plate dowels into the

sleeves by puncturing the protective cover strips.

The plate dowels should be completely inserted

into the sleeves.

4. Position and tie any remaining slab reinforcement.

The adjoining slab can now be placed against

the face of the first and the exposed steel plate

dowels. Place concrete normally, completely

surrounding each plate dowel location.
