Concrete And Plastic Spacers Starting At 15 Cents Each

Spacers

The use of spacer in the forming before your pouring, guaranties the concrete recovering needed to comply with the position of the rebar. This position is responsible for the mechanical properties of the final concrete body. Yes, it is that important to use spacers.

Plastic spacers:

These all purpose spacers are the most extensively used for concrete walls, columns, beams, etc, both on site and in pre-cast for a wide variety of reinforcement bar diameters. Designed to allow unimpeded concrete flow through the spokes and to assure the minimum contact to the formwork and maximum load capacity.

Design to keep distances for concrete covering of 2,5 cm and 3,5 cm; Other sizes can be made on order.

Concrete spacers:

The main characteristics are:

• natural bonding with concrete
• suitable for horizontal or vertical fixing of bars
  
• a minimum strength of 180/cm² after 28 days
• an identical co-efficient of expansion and contraction to that of your site concrete.
• An alternative spacer for supporting mesh in slabs, columns, beams, and any concrete body.
• Has a wide base for use on polythene membranes, sand or hardcore.
• Available sizes of:  10mm, 25mm, 35mm, 50mm, 75mm. Other sizes made on order.
