INTERCHEM R

Interchem R, denoting “Rebuild”, is a general-purpose epoxy-mortar repair system used to rebuild severely gas attacked underground sewer structures which may also have some structural loss. Interchem R is recommended when the condition of the structure has deteriorated to the point where protection from Interchem P is no longer adequate.

Interchem R is a three-stage rebuild and coating system consisting of an;

1. Epoxy based primer
2. 20mm thick epoxy-aggregate filler
3. Epoxy glaze top-coat.

Prior to application the surfaces are cleaned with high pressure water. The epoxy primer provides Interchem R with a strong bond to the substrate. The epoxy- aggregate filler is mixed and applied by trowel in two layers each at10mm thick to achieve a final 20mm thick structure. The restoration is then finished by applying three coats of epoxy top-coat glaze.  The epoxy glaze gives additional surface protection against abrasion and chemical attack. The 3 layers of construction provide an optimum combination of features resulting in a finished product that is strong, tough, hard-wearing, durable and resistant to chemical attack.

Being epoxy based, Interchem R has excellent chemical resistance, higher abrasion resistance, higher resistance to cracking and longer expected service life compared to conventional cementitious repair methods. This means a higher quality restoration perfectly suited to sewer applications. 

Interchem R is easy to apply making it safe and low risk. It is applied by trowel to where it is needed meaning it can be used for localised patch repairs as well as reaching confined spaces which are beyond the reach of spray systems.

Interchem R rebuilds, seals, and protects severely gas attacked sewer structures cost-effectively renewing and extending the life of the asset. Typical applications are the rebuild of inspection pits , access chambers, manholes, box culverts sections, and localised repair of damaged sections of man entry size pipes.
