Joint Sealants

AG manhole units can be jointed quickly and easily using extruded butyl rubber sealants.

Butyl rubber has an excellent reputation for longevity and offers many advantages over oil mastic type sealants, providing flexibility and cost savings.

  • Produces seal without squeeze-out, reducing the volume of sealant required.
  • Forms an immediate seal.
  • Low temperature flexibility.
  • Resistant to hardening after aging.
  • Permanent flexibility.
  • Various sizes to suit needs.

Tokstrip and primer are also available.

Manhole Steps

A system that offers the contractor the advantages of a durable plastic encapsulated rung.

All AG manhole rings are supplied with eyelets to enable single fixing of either single or double steps on site.

  • They can be quickly and easily installed by semi-skilled labour.
  • There are fewer joints which reduce the likelihood of infiltration.
  • All concrete manhole units can be ordered from one source.
  • There is a reduced risk of on-site damage and pilferage.

Manholes with Ladders

A flexible, convenient solution.

A system that offers the contractor the advantages of a durable plastic encapsulated ladder without the need to specify an exact length or fit for each individual manhole. They're quick and easy to insert, providing savings in labour costs.
