<p>The invention concerns a method for casting bi-constituent solventless resin with a low pressure bi-constituent pump for protecting in situ underground cables, said cables being electric or telephone cables or even optical fibres. The cast resin can be pure or filled. The fillers can be selected according to the properties for which protection is sought (fire resistance, protection against nuclear radiation, electromagnetic armouring). A resin mortar can also be produced by incorporating aggregates in the resin. The invention discloses several processes for producing said mortars during casting.</p> |
