Sealants - Fire Stopping Systems

CRI has been reinstating fireproofing on steel structures, vessels, furnaces, boilers and tanks by removing expired and damaged fireproof protection and replacing it with new cementitious fire protection material. The bulk of these projects have been done on petrochemical refineries.

Our expertise encompass the supply and installation of the following sealant fire stopping systems.

PYROPRO® – HPE

PyroPro® HPE Sealant is a water based acrylic sealant used to reinstate the fire resistance of wall and floor constructions in apertures when penetrated by single or multiple services. PyroPro® HPE Sealant has been developed utilizing specialist intumescent technologies which result in the sealant expanding in the presence of heat or fire to reinstate fire resistance where combustible services are present. The expansion of PyroPro HPE is fast acting and up to 25 times. The expanding sealant fills the void left by combusting materials and remains in place, exerting a pressure on the surrounding substate upholding the fire resistance of the compartment.
